What is Indexing in SEO? (Google Indexing in SEO)

Your latest blog post went live three weeks ago. You crafted every word, optimized your keywords, and built quality backlinks. But when you search for it on Google, nothing shows up.

The culprit? Your page isn’t indexed.

Here’s the reality: only 64.86% of new pages get indexed within the first 30 days, and 76.81% within three months. Even worse, 21.29% of indexed pages eventually get deindexed.

This guide cuts through the complexity. You’ll learn what indexing actually is, why it matters, how to check your status, and how to fix indexing problems that block your content from reaching searchers.

What Is Indexing in SEO?

Indexing in SEO refers to the process where search engines organize and store information about URLs. Think of it as Google’s massive library system. Before your content can compete for rankings, it must first make it onto the shelf.

When Google crawls your page, it analyzes the content, images, metadata, and structure. That information gets stored in Google’s index, a database exceeding 100 million gigabytes.

The Simple Truth About What Is Indexing in SEO

Content that’s not in the index has zero possibility of ranking for a search result. Every other SEO tactic becomes worthless if your pages aren’t indexed, including:

• Keyword optimization
• Backlink building
• Technical improvements
• Content updates

Well-indexed websites rank higher in search results, which increases visibility and drives more traffic to your site, leading to more conversions and sales.

How Indexing Differs from Crawling

People often confuse crawling and indexing. Here’s the distinction:

Crawling is discovery. Search engine bots (crawlers or spiders) systematically browse the internet to discover and access web pages.

Indexing is storage. After crawling, search engines analyze the page and decide whether to add it to their index.

Ranking is positioning. Indexed pages then compete for placement in search results based on relevance and quality signals.

You can’t skip steps. A page must be crawled before it can be indexed, and it must be indexed before it can rank.

How Google’s Indexing System Actually Works

Google’s index is a database of web pages that Google knows about. Once pages are indexed, Google can use information about their content to decide whether to show them in search results.

The Three-Stage Process

Stage 1: Discovery

Google finds your URL through:

• Links from other websites
• XML sitemaps submitted to Google Search Console
• Internal links on previously indexed pages
• Direct submissions via URL Inspection Tool

Stage 2: Crawling

Google has sophisticated algorithms that define which URLs should be prioritized. Googlebot visits pages that meet the priority threshold. Not all discovered pages get crawled immediately or ever.

Stage 3: Index Building

Google analyzes the page content, extracts text and media, processes the HTML, and stores this information. Search engines use an inverted index (reverse index) where pages are stored by keywords rather than requiring searches to sift through individual sites.

What Google Stores in the Index

For each indexed page, Google catalogs:

• Page content (text, images, videos)
• Metadata (title tags, descriptions)
• Page structure (headings, links)
• Load speed and Core Web Vitals
• Mobile usability
• Structured data markup
• Last modified date

Current Indexing Reality: 2025 Data

The numbers reveal the challenge:

• 14% of pages get indexed within the first week
• 27.4 days average indexing time
• 93.2% of pages that will be indexed are indexed within 6 months
• 13.7% of indexed pages get deindexed within 3 months

Google’s John Mueller states that indexing a new page can take anywhere from several hours to several weeks. But when weeks turn into months, you’ve got a problem.

The 10 Most Common Indexing Issues (And How to Fix Them)

1. Noindex Tags Blocking Pages

The Problem: A meta robots tag or X-Robots-Tag HTTP header tells Google not to index the page.

How to Check: Use the URL Inspection Tool in Google Search Console. Look for “Page is not indexed: Excluded by ‘noindex’ tag.”

The Fix: Remove the noindex directive from pages you want indexed. Check your:

• Meta tags: <meta name="robots" content="noindex">
• HTTP headers
• Plugin settings (especially SEO plugins)

2. Robots.txt File Blocking Crawlers

The Problem: Robots.txt files that block important pages confuse search engines and affect their ability to crawl and index your site.

How to Check: Visit yoursite.com/robots.txt and look for Disallow directives that might block critical pages.

The Fix: Update your robots.txt file to allow crawling of important content. Use Google Search Console’s robots.txt Tester to validate changes.

3. Low-Quality or Thin Content

The Problem: Low-quality content includes content that provides little value, content generated solely to manipulate rankings, or content that lacks originality, credibility, clarity, or expertise.

How to Check: Pages with under 300 words, duplicate content, or minimal value often show “Crawled – currently not indexed” status.

The Fix:

• Expand thin content with substantial, original information
• Add data, examples, expert insights
• Create high-quality content that aligns with E-E-A-T criteria
• Consider merging similar pages into comprehensive resources

4. Duplicate Content Problems

The Problem: Multiple pages with identical or very similar content split ranking signals and confuse indexing.

How to Check: Search for exact phrases from your content in quotes. Use tools like Screaming Frog to identify duplicate title tags and descriptions.

The Fix:

• Implement canonical tags pointing to the preferred version
• Use 301 redirects for unnecessary duplicates
• Apply parameter handling in Google Search Console

5. Poor Site Architecture

The Problem: Googlebot may become lost in intricate webs of inner pages with too many layers, especially in sites without a flat design where each page is only a click or two from the homepage.

How to Check: Audit your site structure. Pages more than 3-4 clicks from the homepage often struggle with indexing.

The Fix:

• Create a flat site architecture
• Build a logical internal linking structure
• Fix orphan pages by adding internal links pointing to them
• Ensure important pages are linked from the homepage or main navigation

6. Mobile Optimization Failures

The Problem: Google uses mobile-first indexing, so Googlebot crawls the mobile version of your website first. Poor mobile experiences prevent indexing.

How to Check: Use Google’s Mobile-Friendly Test tool and check Mobile Usability reports in Search Console.

The Fix:

• Implement responsive design
• Ensure mobile and desktop content match
• Fix viewport configuration issues
• Optimize mobile page speed

7. Slow Page Speed

The Problem: Web crawlers stick to a crawl budget. If your website takes too long to load, crawlers may run out of time.

How to Check: Run Google PageSpeed Insights. Scores below 50 indicate serious issues.

The Fix:

• Compress images
• Enable browser caching
• Minimize CSS and JavaScript
• Use a Content Delivery Network (CDN)
• Upgrade hosting if necessary

8. Server Errors and Downtime

The Problem: Pages returning 4xx or 5xx status codes can’t be indexed. Google’s indexing pipeline doesn’t consider URLs that return a 4xx status code for indexing, and URLs already indexed that return a 4xx code are removed from the index.

How to Check: Monitor the Coverage report in Google Search Console for server errors.

The Fix:

• Fix broken pages (404s) with redirects or restored content
• Resolve server configuration issues causing 500 errors
• Monitor uptime and address hosting problems

9. Missing or Incorrect XML Sitemap

The Problem: An XML sitemap helps Google navigate the structure of your website. Without one, Google may miss important pages.

How to Check: Look for your sitemap at yoursite.com/sitemap.xml. Verify it’s submitted in Google Search Console.

The Fix:

• Ensure your sitemap is updated and includes all important pages
• Submit it in Google Search Console under the Sitemaps section
• Remove URLs you don’t want indexed
• Keep the sitemap under 50,000 URLs per file
• Update it when adding new content

10. JavaScript Rendering Problems

The Problem: Content rendered only through JavaScript may not be indexed if Google can’t execute the scripts properly.

How to Check: Use the URL Inspection Tool and compare the rendered HTML with your source code.

The Fix:

• Implement server-side rendering or pre-rendering
• Use dynamic rendering for search bots
• Ensure critical content appears in the initial HTML

How to Check If Your Pages Are Indexed

Method 1: Site Search Operator (Quick Check)

Type site:yourwebsite.com into Google. This shows all indexed pages from your domain.

For specific pages: site:yourwebsite.com/specific-page-url

Limitation: This method shows approximate results and isn’t perfectly accurate.

Method 2: Google Search Console (Most Accurate)

Step 1: Navigate to the Pages report under Index in the left sidebar.

Step 2: Review the summary showing indexed vs. not indexed pages.

Step 3: Click on specific issues to see affected URLs.

Step 4: Use the URL Inspection Tool for individual pages:

• Enter the URL
• Check indexing status
• Review any coverage issues
• See last crawl date

Method 3: Third-Party SEO Tools

Tools like Ahrefs, SEMrush, and Screaming Frog can:

• Track indexing changes over time
• Identify patterns in indexed vs. non-indexed pages
• Alert you to deindexing events
• Compare your indexed pages to competitors

How to Get Your Pages Indexed Faster (Proven Methods)

1. Submit Your URL for Indexing

You can ask Google to index your URL through Google Search Console.

Process:

1. Open URL Inspection Tool
2. Enter your page URL
3. Click “Request Indexing”
4. Wait for confirmation

Important: If there’s a reason Google will prefer to skip indexing this particular page, it will often tell you why in the details.

Limitation: You can only request a limited number of URLs per day. Use this for high-priority pages.

2. Build High-Quality Internal Links

Providing a good network of internal links means Google bots will discover your web pages more quickly and improve your crawl budget.

Best Practices:

• Link to new pages from your homepage
• Add contextual links from related high-authority pages
• Include new content in your main navigation or category pages
• Update old content with links to new pages

3. Create and Optimize Your XML Sitemap

Your sitemap serves as a roadmap for crawlers.

Optimization Checklist:

• Include only canonical, indexable URLs
• Remove parameter URLs
• Set priority tags (though Google mostly ignores these)
• Update the <lastmod> date when content changes
• Submit the sitemap immediately after publishing new content

4. Improve Page Quality Signals

Google may slow down how it indexes your site after it calculates your site’s value compared to the rest of the web and competitors.

Quality Improvements:

• Add original research or data
• Include expert quotes and citations
• Ensure comprehensive coverage of topics
• Update outdated information
• Add images, videos, and other media
• Improve E-E-A-T signals (credentials, author bios)

5. Build External Backlinks

Links from other sites signal that your content deserves to be in the index.

Tactics:

• Share new content on social media
• Reach out to industry sites for mentions
• Guest post with links back to your content
• Create linkable assets (data, tools, resources)
• Get featured in roundups or resource lists

6. Maintain Publishing Consistency

Google’s John Mueller noted: “It’s really hard to call a site authoritative after 30 articles, and especially if you’ve stopped publishing for a while, I can see how Google might be a bit more conservative with indexing.”

Strategy:

• Publish on a consistent schedule
• Don’t go silent for long periods
• Build content depth before expanding topics
• Demonstrate ongoing site maintenance
