How to Get Your Blog Indexed by Google丨Complete These 6 Steps for 100% Indexing

To have a blog indexed by Google, you need to ensure the following:

• ​Submit an XML Sitemap, which increases the indexing rate by over 50%.
• ​Optimize Robots.txt to avoid blocking key pages.
• ​Acquire a large number of backlinks from unique domains (DA≥1), with 300-500 or more, which speeds up indexing by 3-5 days.
• ​Publish original content (≥800 words), which increases the indexing rate by 70%.

According to official Google data, there are over 3.5 billion search queries every day, but only 5%-10% of web pages make it to the first page of search results. For a new blog, Google takes an average of 14-30 days to complete the first index, and technical errors can cause 80% of pages to fail to be indexed.

Data shows that websites that submit a sitemap using Google Search Console (GSC) have an indexing speed increase of over 50%; for every 1-second delay in mobile loading speed, the bounce rate increases by 32%.

For websites with a logical internal linking structure, the crawler’s crawling depth increases by 3 times, while pages with at least 20 high-quality backlinks see an average ranking increase of 11 positions.

Ensure Your Blog Can Be Crawled by Google

Googlebot crawls over 130 trillion web pages every day, but about 25% of websites fail to be indexed due to technical issues. Data shows that for blogs that do not submit a sitemap, the indexing rate decreases by an average of 40%; for websites with robots.txt blocking errors, crawl requests are directly reduced by 75%.

Poor mobile compatibility can cause 53% of users to bounce within 3 seconds, which indirectly lowers the crawler’s crawling frequency.

HTTPS-encrypted pages have a 15% higher indexing priority than HTTP pages, and pages that take longer than 3 seconds to load have a 50% lower probability of being fully crawled by Google.

Server Stability and Response Speed

Googlebot has a clear threshold for server response time. If the average response time for five consecutive crawl requests exceeds 2 seconds, the crawler will actively reduce its access frequency. According to HTTP Archive data, 89% of the top 1000 blogs worldwide have a server response time of under 800 milliseconds, while websites with delays of over 1.5 seconds see their index volume decrease by an average of 30%.

When choosing a hosting service, it’s recommended to prioritize testing TFFB (Time to First Byte); the ideal value should be below 600 milliseconds. For example, using Cloudflare’s CDN can compress global access latency to 200-400 milliseconds, whereas unoptimized shared hosting can be as high as 1.5-3 seconds.

Correct Configuration of Robots.txt

By default, the robots.txt generated by CMSs like WordPress may contain incorrect rules, such as mistakenly blocking CSS/JS files (accounting for 17% of cases), which prevents Google from rendering the page layout. The correct way is to only block sensitive directories (like /wp-admin/), but keep /wp-content/ and /wp-includes/ open to allow resource loading.

You can use Google Search Console’s “robots.txt tester” to verify rules in real-time. Data shows that after fixing errors, crawl volume increases by an average of 65%. Note: Even if robots.txt allows crawling, if a page is marked as noindex, it will still not be indexed—these are independent mechanisms.

Avoid Misusing noindex and Login Walls

About 12% of WordPress users mistakenly add a noindex tag to their entire site due to plugin conflicts or theme settings. You can check the page source code for <meta name="robots" content="noindex"> to confirm. Another common issue is “partially blocked content,” such as requiring users to scroll, click “expand,” or register to see the full text, which results in Googlebot only crawling 30%-50% of the page content.

The solution is to use “structured data markup” (like the isAccessibleForFree property for Article) to explicitly label the access permissions.

Sitemap Generation and Submission

The XML sitemap must contain all important URLs, and a single file should not exceed 50,000 links or 50MB in size (if it does, you need to split it). Data indicates that for blogs without a submitted sitemap, Google takes an average of 22 days to discover new pages, while submitting one shortens this to 7 days. Dynamically generated sitemaps (e.g., via the Yoast SEO plugin) are more reliable than static files, as they can automatically reflect the update frequency (<lastmod> tag).

Note: A sitemap only provides “suggestions”; actual indexing still depends on page quality and crawler priority.

Mobile Adaptation and Core Web Vitals

Since the full activation of mobile-first indexing in 2021, Googlebot defaults to using a mobile user agent (UA) to crawl pages. If the mobile version has missing content or a messy layout, it directly leads to 38% of pages being demoted. In Core Web Vitals, LCP (Largest Contentful Paint) should be below 2.5 seconds, FID (First Input Delay) should be less than 100 milliseconds, and CLS (Cumulative Layout Shift) score should be controlled to be below 0.1.

For example, converting above-the-fold images to WebP format can reduce LCP time by 40%, while lazy-loading non-critical JS can improve FID by 20%-30%.

URL Structure and Internal Link Optimization

Dynamic parameters (like ?sessionid=123) can cause the same content to be indexed repeatedly, wasting crawl budget. You should use a canonical tag (<link rel="canonical">) to specify the preferred version, which can reduce duplicate pages by 70%. For internal links, each article should contain at least 3-5 relevant internal links so that the crawler can reach all important pages within 3 clicks.

Tests show that URLs with more than 4 levels (e.g., /cat1/cat2/cat3/post/) have a 60% lower crawl probability than a flat structure (/blog/post-title/).

HTTPS Encryption and Security Protocols

Websites that do not enable HTTPS will be marked “not secure” by Chrome, and their Google indexing priority will be reduced by 15%. Let’s Encrypt provides a free certificate. After deployment, you need to ensure a site-wide 301 redirect from HTTP to HTTPS and update the protocol in the sitemap.

Mixed content (HTTPS pages loading HTTP resources) triggers browser warnings and causes an LCP delay of 0.8-1.2 seconds. Using Security Headers (like Strict-Transport-Security) can further strengthen the security rating.

Monitoring and Troubleshooting Tools

Google Search Console’s “Coverage report” lists all indexing errors, such as “Submitted URL blocked by robots.txt” (accounting for 34% of error types) or “Page with noindex tag” (accounting for 28%). Regular checks can reduce undiscovered crawl issues. Log analysis tools (like Screaming Frog) can simulate crawler behavior. Data shows that after fixing 404 errors, the effective crawl volume increases by an average of 45%.

For large websites, you can use the Indexing API to push updates for high-priority pages in real-time.

Actively Submit Your Content to Google

Google processes over 5 billion search queries every day, but the average natural discovery cycle for new pages is 14-30 days. Data shows that for websites that do not actively submit content, only 35%-50% of pages are eventually indexed, while for blogs that use Google Search Console (GSC) to submit a sitemap, the indexing rate increases to over 85%.

For pages manually requested for indexing through the “URL Inspection tool,” the average indexing time is shortened to 2-7 days, but the daily submission quota is limited by the site’s authority (new sites get about 10-50 per day, while high-authority sites can get up to 500 per day).

Google Search Console (GSC) Registration and Verification

GSC is a free tool provided by Google that covers 92% of key SEO data. Among the methods for verifying site ownership, HTML file upload (with a success rate of 98%) and DNS record verification (applicable to the entire domain) are the most reliable, while Google Analytics association verification may fail due to code deployment errors (accounting for about 15% of cases).

After verification, you need to confirm the preferred domain (with or without www) in the “Property settings.” Incorrect configuration can lead to duplicate content issues, causing a 20%-30% drop in index volume.

High-permission accounts (e.g., enterprise version) can enable “Enhanced reports,” which provide page-level crawl frequency and index status history.

Sitemap Generation and Submission Standards

The XML sitemap must comply with W3C standards and include the <loc> (URL), <lastmod> (last modified time), and <changefreq> (update frequency) tags. Dynamically generated sitemaps (e.g., via the Yoast SEO plugin) are more reliable than manually created static files, with a 75% lower error rate. A single file is limited to 50MB or 50,000 URLs; if it exceeds this, you must split it into sub-files and integrate them through an index sitemap.

Data shows that websites that submit a sitemap are indexed an average of 60% faster than those that rely on natural crawling, but note that a sitemap only provides a hint, and actual indexing still depends on page quality (about 40% of submitted URLs may be filtered).

Manual URL Submission and Quota Management

GSC’s “URL Inspection tool” allows you to directly enter a specific page address and request indexing, which has a higher priority than natural crawling. Tests show that the indexing probability for the first submitted URL of a new site is 90%, but the daily quota is limited (usually 10-50 times/day). Once exceeded, you must wait 24 hours for it to reset. For time-sensitive content (like news), you can use the “Indexing API” (which has a higher quota but requires technical deployment).

Common errors include:

• Submitting the same URL repeatedly (wasting quota)
• Submitting pages blocked by robots.txt (success rate is 0%)
• Submitting old links without updated content (Google may ignore them)

Indexing API

The Indexing API allows for programmatic URL submission, suitable for websites with a large volume of content (e.g., e-commerce or news platforms). After OAuth 2.0 authentication, a single request can push 100-200 URLs, and the indexing speed is 3-5 times faster than traditional methods. The API supports two request types: URL_UPDATED (to update an existing page) and URL_DELETED (to remove invalid content).

Data shows that websites using the API have their average indexing delay reduced from 72 hours to 6-12 hours, but misconfiguration (such as invalid JSON format) can cause 30% of requests to fail. The development documentation recommends using log monitoring tools (like Google Cloud Logging) to troubleshoot issues in real-time.

Sitemap and Internal Links

Websites that rely solely on sitemaps have a crawl rate of only 40%-60% for deep pages (e.g., below the third category level), while those that combine internal link optimization can reach 90%. It’s recommended to add a “related recommendations” module (at least 3-5 internal links) at the bottom of each article and use breadcrumb navigation (which increases crawl depth by 2-3 levels).

Pages marked with 1.0 in the sitemap do not directly improve ranking but can guide the crawler to prioritize them (homepage and core sections are recommended to be set to 0.8-1.0, and regular articles to 0.5-0.7).

Handling Index Exclusions and Coverage Reports

GSC’s “Coverage report” lists four types of issues: Errors (like 404s), Valid with exclusions (like duplicate content), Needs improvement (like noindex tags), and Indexed. Data shows that 62% of websites have “valid but not indexed” pages, mainly due to insufficient content quality or lack of crawl value.

Solutions include:

• Increasing the number of internal and external links to that page (to improve its importance score)
• Increasing content depth (e.g., expanding from 300 words to 1500 words)
• Using <meta name="robots" content="max-snippet:-1"> to enhance snippet display
• For pages mistakenly identified as “duplicates,” you can fix them with a canonical tag (rel="canonical")

Multi-language and Geo-targeting Submission Strategies

Multi-language websites need to create a separate sitemap for each language version and use the hreflang tag to specify the language/region relationship (e.g., <link rel="alternate" hreflang="en" href="...">). Incorrect configuration can lead to 50% of pages not being properly indexed. In the GSC “International Targeting” report, you can set a geographic target (e.g., target a .de domain to German users).

Note: This only affects the ranking in Google local search and does not change the index itself.

For global content, it’s recommended to use a generic top-level domain (like .com) and rely on hreflang tags.

Monitoring and Continuous Optimization

Check the GSC “Index status” chart weekly; the number of indexed pages for a healthy website should show a steady upward trend (with a fluctuation of less than 15%).

An abnormal drop may be due to:

• Server failure (spike in crawl errors)
• Mistakenly adding a noindex tag
• Algorithm updates (e.g., quality filtering)

For pages that are not indexed, you can use the “URL Inspection tool” to see the specific reason (e.g., “Crawled – not indexed” usually indicates insufficient content value).

For URLs that have not been visited for a long time (over 90 days), consider rewriting them or using a 301 redirect to a relevant page to free up crawl budget.

Create High-Quality, Original, and Relevant Content

Data shows that articles between 1,500-2,500 words on average rank 28% higher than shorter content, while pages with insufficient originality (duplication rate over 30%) have a 65% lower chance of being indexed.

User behavior signals are also crucial: pages with a bounce rate below 40% have a 3x increase in ranking stability, and content with a dwell time of over 3 minutes sees a 50% increase in click-through rate (CTR) in search results.

Keyword Research and Semantic Coverage

Google’s BERT algorithm can now understand over 90% of long-tail query intentions, and the effectiveness of simply matching keyword density (e.g., 2%-3%) has decreased by 60%. Effective practices are:

• Use tools (Google Keyword Planner, Ahrefs) to filter for long-tail keywords with a search volume of 100-1,000/month (e.g., “how to brush a cat’s teeth” instead of “pet care”). These keywords have a 35% higher conversion rate than generic ones;
• Naturally include the main keyword in the title (H1), the first 100 words, and H2/H3 subheadings, but avoid repeating it more than 3 times (which may trigger over-optimization filtering);
• Cover LSI (Latent Semantic Indexing) related words. For example, an article about “coffee machines” should include terms like “grind size” and “brewing pressure,” which can increase content relevance score by 40%.

Content Depth and Information Increment

Google’s “in-depth content” standard requires a page to provide more detail or a unique perspective than the TOP 10 results. Comparative analysis shows:

• Articles that include a step-by-step guide + data charts + case comparisons have 2.1 times higher ranking stability than pure text content;
• Adding original research (e.g., small survey data) can increase a page’s authority score by 25% (you need to state the data source and methodology);
• Video embeds (like YouTube tutorials) can extend the average dwell time by 1.5 minutes, but they need to be accompanied by a text summary (the crawler cannot parse video content).

Originality Check and Avoiding Duplication

Pages with a duplication rate of over 15% detected by Copyscape have a 50% lower chance of being indexed. Solutions include:

• Using tools like QuillBot to rewrite quoted content (maintaining the meaning but adjusting the sentence structure) has an 80% higher indexing rate than direct copy-pasting;
• Adding analytical commentary to public information (like product manuals) (e.g., “we found that the XX feature is more suitable for beginners”)—the original part needs to account for over 70% of the full text;
• Regularly updating old articles (at least every 6 months) and adding new paragraphs can re-enter the page into the index priority queue (the effect lasts for 30-90 days).

Readability and Content Structuring

Content with a Flesch Reading Ease score between 60-70 (middle school level) has the highest user engagement. Specific methods:

• Control paragraph length to **3-4 lines**; paragraphs longer than 7 lines increase bounce rate by **20%**;
• Use bullet points (•) or numbered lists (1.2.3.) to increase the scanning efficiency of key information by **50%**;
• Insert **1-2 images** (with alt text) for every 1,000 words; pages with mixed text and images have **120%** higher social sharing volume than pure text ones.

Matching User Intent and Content Type Selection

Google classifies search intent into four categories (Navigational, Informational, Commercial, Transactional). Misjudging the intent can cause a CTR drop of 60%. Examples of judgment criteria:

• A search for “iPhone 15 review” needs to provide a comparison table + pros and cons list (informational);
• A search for “where to buy cheap iPhone 15” should recommend a dealer price comparison + discount codes (transactional);
• A search for “what to do if iPhone freezes” needs step-by-step troubleshooting (use H2 to label “Solutions”).

Content Updates and Maintenance

• YMYL (Your Money or Your Life) content such as medical/financial topics needs to have data updated every 3 months (outdated information can cause a 75% ranking drop);
• Adding the last updated time to the top of the article (e.g., “Revised July 2024”) can increase the probability of Google re-crawling by 40%;
• For old articles with declining traffic, adding an “FAQ” module (FAQ Schema) can recover a 15%-25% click-through rate.

Structured Data Enhancement

• Pages with HowTo or Recipe structured data have a 90% higher rich snippet display rate in search results;
• Infographics get 3 times more natural backlinks than text (you need to provide embed code);
• Transcribing podcast content into text increases the indexing coverage from 20% for audio to 95%.

Content Quality Assessment Tools

• In Google Search Console’s “Search performance report,” pages with a CTR below 2% need to have their title/description optimized;
• A “Content rendering speed” of over 2.5 seconds in PageSpeed Insights leads to a 30% decrease in reading completion rate;
• Duplicate meta descriptions detected by Screaming Frog need to be modified (if they account for over 15%, they will dilute the page’s uniqueness).

Build a Strong Internal Linking Structure

Googlebot discovers and assesses page importance through internal links. Data shows that a well-optimized internal linking structure can increase the overall indexing rate of a website by 65% and improve the ranking stability of important pages by 40%.

Tests show that URLs with more than 4 levels (e.g., /category/subcat/page/) have a 60% lower crawl probability than a flat structure (/page-title/), and when each article contains 3-5 relevant internal links, the average number of pages viewed by a user increases by 2.3 times.

Internal Links

Directly affect three core metrics:

• Crawler efficiency: The probability of finding isolated pages with no internal links is less than 20%, while pages that can be reached within 3 clicks from the homepage have an indexing rate of 95%;
• Weight distribution: In Google’s PageRank algorithm, for every 1x increase in the number of internal links, the target page’s authority value increases by 15%-30% (but avoid over-interlinking, which can cause dilution);
• User behavior: Articles containing contextually relevant internal links have an average dwell time increase of 1.8 minutes and a bounce rate decrease of 25%.

Website Architecture Depth Optimization

• Flat structure: Ideally, all important pages should be reachable within 2-3 clicks from the homepage (e.g., Home >
Category > Article). Tests show that the crawl completeness of this structure is 70% higher than deep nesting (4+ levels);
• Breadcrumb navigation: Breadcrumbs with structured data markup (BreadcrumbList) can increase the weight transfer efficiency of internal links by 20% and reduce the number of clicks for users to return to the homepage (an average reduction of 1.5 clicks);
• Sidebar/footer links: It’s recommended to only place 5-8 core sections in the global navigation. Too many links (over 15) can lead to weight dispersion, causing a 10%-15% drop in the ranking of key pages.

Contextual Link Anchor Text Optimization

• Natural diversity: Exact-match anchor text (e.g., “coffee machine buying guide”) should account for 30%-40%, with the rest using partial matches (“how to choose a coffee machine”) or generic words (“click to see details”) to avoid being flagged for ranking manipulation;
• Relevance verification: The thematic match between the source and target pages of the link needs to be over 60% (you can use TF-IDF tools to check). Irrelevant links can cause user bounce rates to increase sharply by 40%;
• Position weight: Internal links in the first 100 words of the body text have a 3 times higher click-through rate than those at the end, but they must maintain content flow (forced insertion can disrupt the reading experience).

Content Hubs

• Hub page design: Summarize 10-20 articles on the same topic into a guide (like “The Complete Coffee Manual”) and link them bidirectionally with internal links. This can increase the overall ranking of that topic by 25%;
• Hub & Spoke model: The central page (Hub) allocates 50% of internal links to sub-pages (Spokes), and the sub-pages link back to the central page with 70%-80% of their links. This structure increases topic authority 2 times faster than a disorganized link structure;
• Update synchronization: When the hub page’s content is refreshed, all associated sub-pages can automatically receive a weight boost via internal links (an average 5%-10% ranking increase).

Avoid Common Errors

• Orphan pages: When the proportion of pages with no internal links pointing to them exceeds 15%, the overall indexing rate drops by 30% (you need to use Screaming Frog to scan and fix this);
• Duplicate links: When the same page links to the same target multiple times (more than 3 times), the weight transfer efficiency of additional links decays to below 10%;
• Low-quality associations: Linking from an authoritative page (like the homepage) to thin content (under 300 words) can cause the homepage’s ranking to drop by 8%-12% (prioritize linking to in-depth content of 1500+ words).

Dynamic Links and Personalized Recommendation Systems

• Algorithmic recommendations: Using user behavior data (like browsing history) to dynamically generate “you might like” internal link modules can increase the click-through rate by 50% (note that crawlers cannot parse links loaded by JS, so you need SSR or pre-rendering);
• Timeliness control: When a newly published article gets 5-10 internal links in the first week, its indexing speed increases by 40%, but you need to balance the quantity (adding over 50 new internal links per day may trigger a review);
• Broken link monitoring: Check and fix 404 internal links every month (if they account for over 5%, the crawler’s trust will decrease).

Acquire External Links

In Google’s ranking algorithm, the weight of external links accounts for over 25%. Data shows that pages with 100 or more effective external links have a 3 times higher ranking stability than pages without them. But not all external links have the same value—an external link from a domain that has not been indexed by Google has a voting power close to 0, while an external link from a website with a high indexing rate (>80%), even with a domain authority (DA) of only 1, can still pass on effective weight.

For anchor text distribution, brand terms (e.g., “Zhihu”) and generic terms (e.g., “click here”) should account for 60%-70%, and exact-match anchor text (e.g., “coffee machine recommendations”) should be controlled to be below 30% to avoid the risk of over-optimization.

The Underlying Logic and Indexing Principles of External Links

• Indexing is the prerequisite: The external link source page must be indexed by Google (you can check with site:domain.com). Unindexed external links cannot pass on weight (they account for about 40% of inefficient external links);
• Quantity first: Tests show that for every 1x increase in the number of external links, the ranking potential of the target page increases by 15%-20% (the marginal effect decreases, but continuous accumulation is effective);
• Anchor text diversity: In a natural backlink distribution, brand terms (e.g., “Taobao”) account for 35%, generic terms (e.g., “visit official website”) account for 25%, partial-match terms (e.g., “learn SEO techniques”) account for 30%, and naked URLs (e.g., https://example.com) account for 10%. When manually building links, you need to simulate this ratio.

High-ROI External Links

• DA > 1 is effective: For low-DA (1-10) but normally indexed websites, the cost per external link should be controlled between 8-12 USD, while the cost for high-quality resources with DA > 30 can exceed 40 USD/link (you need to weigh the ROI);
• Indexing rate check: Use Ahrefs/SEMrush to scan the target domain’s indexing rate (indexed pages/total pages). The value of external links from websites with an indexing rate below 60% decreases by 70%;
• Websites do not need to be relevant: Acquiring external links from websites in the same industry is difficult and not quantifiable. For example, if you want to get 10,000 links, you can’t find 10,000 peers, so getting dozens to hundreds of links is meaningless. The reverse link numbers for the Top 3 websites (in any industry) are very large and are not all relevant. Just follow the facts.

How to Acquire a Large Number of Backlinks

• Guest Post: Publish articles on industry websites that allow submissions and embed links. The average cost is 12-20 USD/article, and the article’s originality must be over 70% (checked by Copyscape);
• Resource Link: Find pages like “tool recommendations” or “learning materials” and submit your content (success rate is about 15%). The cost per external link is about 8 USD;
• Forum/Q&A Backlinks: Insert links when answering questions on platforms like Reddit or Quora. Note:
  • Only for relevant content (otherwise, the deletion rate is 90%);
  • External links with a nofollow tag can still bring traffic (accounting for 25% of effective external links).

External Link Costs

• Bulk purchase: Cooperate with small and medium-sized webmasters to buy links in a package (e.g., 50 external links/month). The unit price can be as low as 6-10 USD (you need to spot-check the indexing status);
• Automation tools: Use ScrapeBox to filter for blogs that allow comments (success rate is 5%-10%), but you need to manually review them to avoid spam domains;
• Content exchange: Provide high-quality content (like charts, research reports) to other websites for free in exchange for a natural external link (cost is 0, but it’s time-consuming).

Optimize Page Elements

When Googlebot parses page elements, the weight of the Title tag accounts for about 15%, while the Meta description, although not directly involved in ranking, affects over 35% of the click-through rate (CTR). Data shows that pages with keywords in the URL structure rank 12% higher than those with random character URLs, and websites with images lacking the alt attribute lose 60% of their image search traffic.

Under mobile-first indexing, pages that meet the Core Web Vitals have an average ranking increase of 7 positions, and an LCP (Largest Contentful Paint) of over 2.5 seconds can cause the bounce rate to increase by 53%.

Title Tag Optimization Standards

Google search results display the first 60 characters (the rest are truncated). Tests show that titles containing the target keyword and a length between 50-58 characters have the highest click-through rate (it’s 20% higher than titles that are too short/long), and placing the main keyword at the beginning of the title (in the first 3 words) has a 15% better ranking effect than placing it at the end, but it needs to be natural (e.g., “2024 Coffee Machine Buying Guide” is better than “Buying Guide: 2024 Coffee Machine”).

If the proportion of duplicate titles on the entire site exceeds 30%, it will trigger content dilution. It’s recommended to write each page’s title manually or use dynamic variables (e.g., “{Article Name} |
{Brand}”).

Meta Description

• Function: The description tag does not participate in ranking, but an increase in CTR can indirectly boost the ranking (when the click-through rate increases from 2% to 5%, ranking stability increases by 40%);
• Call to action (CTA): Descriptions that include action verbs like “learn now” or “latest data” have a 25% higher click-through rate than neutral statements;
• Length limit: Keep it between 150-160 characters (the rest will be truncated). For mobile, a more concise length (120-140 characters) is recommended.

URL Structure Standardization

Pages with the target keyword in the URL (e.g., /coffee-machine-reviews/) rank 8%-10% higher than those with random IDs (e.g., /p=123). URLs with more than 3 slashes (e.g., /category/subcat/item/) have a 30% lower crawl priority. It’s recommended to use a flat structure (e.g., /category-item/).

Dynamic parameters (?id=123) need to be specified with a canonical tag (rel="canonical") to avoid duplicate content issues (if it exceeds 15%, it will waste crawl budget).

Semantic Use of Heading Tags (H1-H6)

• H1 uniqueness: Each page should have only one H1 tag (with a content difference of no more than 30% from the Title tag). Multiple H1s can cause topic dispersion and a 5%-8% ranking drop;
• Hierarchical logic: H2s are for main sections, and H3s are for sub-paragraphs. Skipping levels (e.g., H1→H3) makes it difficult for crawlers to understand, and the content score will be reduced by 12%;
• Keyword distribution: Naturally including relevant keywords in H2s (e.g., “how to clean a coffee machine”) can increase the paragraph’s weight by 20%.

Image Optimization

Descriptive alt text (e.g., alt="home espresso machine operation demonstration") increases image search traffic by 40%. Blank or keyword-stuffed alt text is ineffective. The WebP format is 50% smaller in file size than JPEG. After LCP optimization, the user dwell time is extended by 1.2 minutes.

Lazy Loading: Lazy-loading images outside the first screen can reduce mobile FID (First Input Delay) by 30 milliseconds.

Structured Data (Schema Markup)

Article markup increases the rich snippet display rate by 90%. FAQPage can occupy more search result space (increasing click-through rate by 15%). Use the Google Rich Results Test to check for errors; invalid markup can lead to a 20% loss of potential impressions.

For product pages with changing prices/stock, use the offers markup and update it regularly to maintain search freshness.

How to Meet Core Web Vitals

• LCP optimization: Compress above-the-fold images + use CDN acceleration to reduce LCP from 3 seconds to 1.5 seconds, which increases ranking by 5 positions;
• FID improvement: Reduce third-party scripts (like social sharing buttons) to keep interaction latency below 100 milliseconds;
• CLS control: Reserve space for images/ads (with width/height attributes) to avoid layout shifts (the score needs to be <0.1).

Mandatory Mobile Adaptation Requirements

• Responsive design: Use @media queries to adapt to screens, which has a 60% lower maintenance cost than a separate mobile domain;
• Touch-friendliness: Button size should not be less than 48×48 pixels, and the spacing should be over 8pt, which reduces the miss-click rate by 40%;
• Font readability: Body text should be no smaller than 16px, and the line height should be 1.5 times, which increases the reading completion rate by 25%.

Through systematic page optimization, your content will get more stable performance in search results.
