Understanding Googlebot: How the Search Crawler Indexes and Ranks Pages


Getting your website properly indexed by Google is crucial for achieving high search engine rankings and visibility. The Google index is the giant database containing all the webpages that Google knows about and can potentially rank and display in search results. If your pages aren’t in Google’s index, there’s no chance of them appearing for relevant searches.

There are a few key factors that may prevent Google from indexing your pages. One is if you have a robots.txt file that blocks crawling of certain pages or sections of your site. You may also use meta noindex tags on some pages, like contact or thank you pages, that tell Google not to index that content. Technical issues like site architecture problems or broken links can also lead to pages not getting crawled and indexed properly. Using duplicate or thin content across pages is another factor that can dilute the strength of your website in Google’s eyes.

Understanding what gets indexed by Google and optimizing your site to facilitate easy crawling is crucial for any website owner. In this post, we’ll explore the Google index more deeply and provide tips for improving your site’s indexing to maximize search visibility.

How Googlebot Crawls Websites

Googlebot starts its crawling process by visiting the most popular and authoritative websites on the internet. These are sites that have many high-quality external links pointing to them, indicating their trust and authority. Googlebot will crawl these sites more frequently to quickly index new content.

From these popular sites, Googlebot then follows the hyperlinks to find new webpages to crawl. It navigates across the web iteratively in this fashion, following links to discover additional websites and pages. This allows Googlebot to map out the connections of the broader internet.

As Googlebot crawls each page, it uses algorithms to parse and analyze page content including text, images, videos, and structured data. It also assesses page elements like titles, headings, links, and URLs.

Googlebot determines how frequently to re-crawl and re-index each page based on multiple factors:

  • Popularity and authority of the site
  • Frequency of page updates
  • Page performance and crawl rate
  • Relevance of page content to search queries
  • Quality of the page based on trust metrics

By continuously crawling in this methodical yet adaptive way, Googlebot maintains a fresh and comprehensive index of the constantly evolving web.

How Googlebot Stores Information About Websites

Googlebot stores the information it collects about websites in the Google Index. The Google Index is a large database that contains information about billions of web pages.

The information stored in the Google Index includes:

  • The URL of the page: This is the unique address of the page on the internet.
  • The text of the page: This includes all of the text that is visible on the page, as well as the text that is hidden in the code.
  • The keywords in the page: These are the words and phrases that are used on the page.
  • The links to other pages: These are the links that are on the page that point to other pages on the internet.

Googlebot stores this information in a variety of ways. Some of the information is stored in text files, while other information is stored in binary files. The specific way that the information is stored is not publicly known.

How Googlebot updates the Google Index

Googlebot updates the Google Index on a regular basis. This means that if you make changes to your website, Googlebot will eventually crawl the changes and update the information in the Google Index.

The frequency with which Googlebot updates the Google Index varies depending on a number of factors, such as the popularity of the website, the freshness of the content, and the relevance of the website to Google’s search index.

In general, Googlebot tries to update the Google Index as quickly as possible. However, there may be times when it takes Googlebot longer to update the Google Index, such as when there is a large amount of new content on the internet.

How to improve the chances of your website being indexed by Google

There are a few things you can do to improve the chances of your website being indexed by Google:

  • Make sure your website is well-structured and easy to crawl. This means using clear and concise URLs, avoiding duplicate content, and using relevant keywords throughout your website.
  • Use relevant keywords throughout your website. This means using the keywords that your target audience is likely to use when searching for your products or services.
  • Get links to your website from other high-quality websites. This will help Google to see that your website is important and relevant.
  • Submit your website to Google Search Console. This will allow you to track the performance of your website in Google search results and identify any problems that may be preventing your website from being indexed.

How Google Uses Google Index to Return Search Results

When you search for a keyword or phrase, Google uses the Google Index to find all of the pages that contain that keyword or phrase. It then ranks these pages according to their relevance to your search query. The most relevant pages are returned as the top search results.

Google uses a number of factors to determine the relevance of a page to a search query. These factors include:

  • The number of times the keyword or phrase appears on the page: This is the most important factor that Google uses to determine the relevance of a page. The more times the keyword or phrase appears on the page, the more relevant the page is considered to be.
  • The importance of the keyword or phrase on the page: The importance of a keyword or phrase is determined by a number of factors, such as the position of the keyword or phrase on the page, the size of the font, and the formatting.
  • The links to the page from other websites: The links to a page from other websites are also a factor that Google uses to determine the relevance of a page. The more links to a page from other websites, the more relevant the page is considered to be.

Other factors that Google may consider

In addition to the factors mentioned above, Google may also consider other factors when determining the relevance of a page to a search query. These factors may include:

  • The freshness of the content: Google prefers to return pages with fresh content, as this is more likely to be relevant to the user’s search query.
  • The quality of the content: Google prefers to return pages with high-quality content, as this is more likely to be helpful to the user.
  • The user’s location: Google may consider the user’s location when returning search results. This is because users in different locations may be interested in different information.
  • The user’s search history: Google may also consider the user’s search history when returning search results. This is because users who have searched for similar terms in the past are more likely to be interested in similar information.

How to improve your website’s ranking in Google search results

There are a few things you can do to improve your website’s ranking in Google search results:

  • Make sure your website is well-optimized for search engines. This means using relevant keywords throughout your website and making sure your pages are easy to crawl and index.
  • Create high-quality content that is relevant to your target audience. This is the most important factor that Google uses to determine the relevance of a page.
  • Get links to your website from other high-quality websites. This will help Google to see that your website is important and relevant.
  • Submit your website to Google Search Console. This will allow you to track the performance of your website in Google search results and identify any problems that may be preventing your website from ranking well.

How to Improve Your Chances of Having Your Website Indexed by Google

Here are some things you can do to improve your chances of having your website indexed by Google:

Make sure your website is well-constructed and easy to crawl

To increase your chances of getting indexed by Google, make sure your website’s structure and content are optimized for search crawlers:

  • Use clear, simple URLs that reflect the topic of each page. For example, name product pages with the product – this helps Google understand relevancy.
  • Avoid duplicate content across pages, as Google will only index the original version. Ensure each page provides unique value to visitors.
  • Organically work relevant keywords into page content to signal to Google what the page focuses on. But don’t overdo it – write for visitors first.
  • Include useful headers, meta descriptions, alt text and other elements to describe your content and make it easy to parse.
  • Structure your site navigation logically and include internal links between related content. This helps Google discover and crawl all pages.

By making your site easy for the search crawler to digest and understand through good technical optimization, you make it more likely your important pages will get properly indexed.

Use relevant keywords througout your website

When creating content, research relevant keywords that your target audience is likely to search for. Incorporate these organically throughout your site’s pages to signal relevance to search engines.

Some tips for choosing effective keywords:

  • Look for terms with decent search volume – enough people searching monthly to indicate interest and traffic potential. But don’t only go after ultra high-volume keywords if they are too competitive.
  • Evaluate competition for each keyword – how many other sites are trying to rank for it? Make sure you can reasonably compete.
  • Ensure keywords directly relate to your products, services or other offerings. Only target phrases relevant to your site’s focus and purpose.
  • Also consider keyword variations and long-tail keyphrases like “best practices for SEO” rather than just “SEO”. These can be less competitive.
  • Use keyword research tools to find search volume data and optimize target terms.

By identifying the right keywords to focus on during content creation, you can attract more opportunities for search visibility and traffic. Just be sure to keep the keywords organic and valuable for your human audience.

Get links to your website from other high-quality websites

Getting quality backlinks pointing to your site from external websites is a great way to boost your perceived authority and relevance in Google’s eyes.

Try to obtain links organically from reputable sites in your industry or niche. For example, if you run a content marketing blog, aim to be featured as a guest post author on other highly-ranked marketing blogs. Or seek citations from well-known directory and review sites related to your business category and location.

When reaching out for backlinks, focus on sites that:

  • Are topically relevant to yours – this shows shared expertise.
  • Have strong trust metrics themselves – authority passes through links.
  • Provide contextual links embedded naturally within content, not just a blogroll list.
  • Will drive interested referral traffic to complement search visibility.

Build relationships with other influencers and publishers in your space to collaborate on content promotion. Don’t simply spam low-quality sites. Quality over quantity applies to backlink building, so be selective.

Submit your website to Google Search Console

Register your website with Google Search Console – this free tool provides valuable data to help improve search presence.

Adding your site to Search Console allows you to:

  • See how your pages are indexed and if any are excluded from results.
  • Check if Googlebot can access all pages or if there are crawl errors.
  • View search analytics to see which queries drive traffic to your site.
  • Discover new link opportunities through backlink reporting.
  • Identify technical issues like page speed or mobile usability.
  • Request indexing of new pages.

Monitoring your site through Search Console gives visibility into how Google views and interacts with your site. Leverage the insights to diagnose problems that may be blocking pages from getting indexed fully. This can help boost your overall search rankings and visibility.

Just be sure to verify your site’s ownership in Search Console to access all features. Take advantage of this free and invaluable resource from Google.

How to Be Sure Your pages are formatted and Contain Unique Content

When creating and publishing webpages, keep search engine optimization best practices in mind to help Google properly index and rank your content. Using clear, concise URLs that reflect the topic makes it easier for Google to understand what each page is about. Avoid duplicating content across multiple pages, as Google will only index one version, so ensure each page offers something new and different for visitors.

Naturally work relevant keywords into your content to signal to Google the focus of that page. But don’t just awkwardly stuff keywords – write pages with your human audience in mind first, while also paying attention to search optimization.

Additionally, get creative with content formats – don’t just use blocks of text. Images, videos, data visualizations, tables, and other multimedia elements make for more engaging pages that encourage visitors to spend more time there. Just be sure to include descriptive alt text for accessibility.

Before publishing any page, be sure to carefully proofread the content to fix typos, broken formatting, and other errors that may frustrate users. Taking the time to polish the content will pay off by establishing your site’s expertise and professionalism.

Do your research before writing to deeply understand the topic and come up with fresh ideas and angles. Don’t be afraid to get creative and stand out from competitors with unique, original content. Use your own natural voice and style, while being honest and transparent about sources and opinions to build reader trust. By keeping these tips in mind as you develop pages, your site will be better structured to be properly crawled, indexed and ranked by Google.

How to Submit Your Pages for Indexing Using the Google Search Console

Google Search Console provides a valuable tool for requesting indexing of new or updated pages on your site. Here are the steps on how to submit your pages for indexing using the Google Search Console:

  1. Go to the Google Search Console website at https://search.google.com/search-console/about and sign in with your Google account credentials.
  2. Click on the “Index” tab in the left sidebar. This will take you to the section for requesting indexing.
  3. Next, click on the “URL Inspection” tool. This allows you to enter individual URLs you want indexed.
  4. Paste or type the full URL of the page you want to submit for indexing into the search bar (for example, https://www.example.com/blog/new-page).
  5. Finally, click the “Request indexing” button. This queues up the page to be crawled and added to Google’s index.

Google will then crawl the submitted page and add it to the search index. However, this process can take some time depending on the number of pages you’ve requested indexing for and the size of your overall website. Larger sites may take longer to crawl than smaller websites. But submitting URLs here is a great way to directly notify Google of new pages you want indexed.

How to Regularly Update Your Pages With New Content

Updating your website pages with fresh content on a regular schedule is crucial both for keeping visitors engaged and for search engines like Google. Here are some tips on how to build a sustainable process for regular content updates:

  • Set a defined schedule for updates based on your resources and needs – such as weekly, monthly or quarterly. Building a routine makes you more likely to stick to it consistently.
  • Before writing, research and analyze your target audience. What are their interests, pain points, and goals? What topics and types of content do they find most helpful? Tailor your updates for what your readers want.
  • Mix up your content formats to keep it interesting. Combine written posts or articles with videos, infographics, photo galleries, quizzes, interviews and more. Variety helps boost engagement.
  • Promote and distribute your new and updated content through email lists, social channels, paid ads and other means. Let your audience know there’s fresh material to explore.
  • Use analytics to see which update styles perform best. Monitor pageviews, time on page, shares, and links to see what resonates. Double down on what works.
  • Consider repurposing existing content. Turn old posts into videos or expand into a series. Refreshing evergreen content can be easier than creating from scratch.

Building a reliable content update process is challenging but worthwhile. The key is sticking to the routine, experimenting to find your audience’s sweet spot, and continuously optimizing based on data.

How to Avoid Using Robots.txt to Block Googlebot From Crawling Your Pages

While blocking Googlebot via robots.txt may seem like an easy solution, there are smarter ways to selectively prevent indexing of pages that don’t require completely restricting crawler access.

  • Use the meta robots noindex tag in the HTML head of pages you want to exclude. This tells all search engine crawlers not to index that page while still allowing it to be accessed.
  • Password protect private pages you don’t want indexed. Requiring login access will block Googlebot and other crawlers from being able to crawl or index the page content.
  • Create a robots.txt file but use allowance directives rather than blocking all access. Specify which bots can access which sections, pages or file types on your site.
  • Implement a content delivery network or CDN. CDNs cache site content on distributed servers, meaning Googlebot will fetch cached page versions rather than crawling your origin servers.
  • Use IP address filtering to block Googlebot and other crawler access to certain pages. This requires technical expertise but can allow access to human visitors.
  • Configure your web server to return 404 or 410 gone status codes for URLs you want to de-index. Googlebot should drop pages from the index when it detects those codes.
  • As a last resort, use the “noindex” directive within robots.txt for specific pages you want to block. This is less granular than the other options.

The key is using the right method for your needs while avoiding completely blocking Googlebot from crawling important sections of your site via robots.txt. A balanced approach helps maintain search visibility.


The Google index is the backbone of the search engine, enabling it to return relevant results for billions of queries. Optimizing your website to get properly crawled, indexed, and ranked in Google is foundational to driving traffic and visibility. By following best practices like good site architecture, quality content, and obtaining reputable backlinks, you can significantly improve your chances of ranking well. Monitor your site through Google Search Console to identify and fix any indexing issues. The search landscape is complex and ever-evolving, but focusing on great user experience and search engine compatibility will serve you well. With a comprehensive indexing strategy, you can unlock the full potential of Google to connect with your audience.
