Crawl Budget

Date created: Dec 07, 2023  •   Last updated: Dec 26, 2023

What is Crawl Budget

A crawl budget refers to the number of page bots from Google crawl and index on a website within a given timeframe. It affects how often and how many of your pages are indexed by Google. For example, if your website has a large number of pages but only a portion of them are indexed, it may indicate that your budget is being allocated inefficiently. This means that Googlebot is not spending enough time crawling and indexing important pages on your website, which could impact your search engine visibility. Another key aspect of this budget optimization is monitoring your website's log files to track how search engine bots are crawling your site. This data can provide valuable insights into crawl patterns, potential issues, and areas for improvement. When you understand and manage your crawl budget, you boost the chances of showing your content to your target audience.

More about Crawl Budget

Google and Bing use their own algorithms to determine which pages to crawl, index, and rank. Understanding crawl budget and how it can impact your website's visibility will give you better control over how search engines perceive and rank your pages.

Let’s delve into what crawl budget is about and how you can leverage it for your website's optimization.

The crawl budget is influenced by two main factors:

Crawl Rate Limit: This aspect is encapsulated in the Server Health Factor (SHF) function, ƒ. The crawl rate limit is determined by how much the search engine's crawler can access your site without negatively impacting its performance. The SHF reflects this by considering server response time, error rate, and downtime frequency. A healthier server (indicated by a higher SHF score) suggests that the site can handle a higher crawl rate without issues.

The function ƒ could look something like this:

ƒ (Server Response Time, Error Rate, Downtime Frequency) = α x (1/Server Response Time) + β x (1/Error Rate) + γ x (1/Downtime Frequency)

Here, α, β, and γ are weights assigned to each factor based on their perceived importance.

Crawl Demand: This is represented by the Content Value Factor (CVF) function, g. Crawl demand is influenced by how valuable or in-demand your content is to the search engine. Factors like update frequency, page importance, and user engagement contribute to this. A higher CVF score suggests that the content is more valuable or in demand, which may increase the crawl demand.

The function g could be structured like:

g(Update Frequency, Page Importance, User Engagement)= δ × Update Frequency + ε × Page Importance + ζ × User Engagement

By combining these two aspects—SHF and CVF—the formula provides a holistic view of the crawl budget.

Best-in-class crawl budget utilization

A website’s optimal crawl rate limit is affected by several factors:

  • Optimal Page Load Time: Websites that load in under 3 seconds typically have a better crawl rate limit.

  • High Crawl Demand: Sites with regularly updated content, good user engagement, and strong backlinks tend to have higher crawl demand.

  • Efficient Use of Budget: Best-in-class websites have minimal duplicate content and broken links, ensuring that the crawl budget is spent on valuable, unique pages.

How Important is a Crawl Budget for SEO?

Basically, if Google doesn’t index a page, it won’t appear in search results. Whether you have a small or large website, you should make sure that your most important crawl pages are indexed and visible in search results.

Here are four key reasons crawl budget is important for SEO:

Prioritize crawling and indexing

Understanding your budget lets you prioritize the most critical things for crawling and indexing. As a result, search engines can efficiently spend time on your site to crawl and index important pages. This way, you make sure that your most important pages are indexed and visible in search results.

Prevent duplicate content issues

If a search engine bot spends too much time crawling and indexing low-value or duplicate content, it can dilute your website’s value. To avoid lower rankings and less visibility, you must optimize your budget and minimize duplicate content.

Optimize site structure

Crawl budget optimization can also help you identify any potential crawl issues. For example, if certain pages on your website are not being indexed, it may indicate a problem with the site structure or internal linking. Aside from boosting visibility, identifying and fixing these issues can help with user experience when browsing your site.

Boost indexation of new content

With the competitive digital landscape these days, getting new content indexed quickly can help you keep up with the competition. A good budget strategy can help with faster indexing, giving your new content a better chance of ranking higher in search results.

How To Find Your Website’s Crawl Budget

You can determine your website's crawl budget through tools, server log files, and third-party SEO apps. Let's take a closer look at each one:

Using search engine tools

Google makes it easy for site owners to monitor their crawl budgets through Search Console. The Crawl Stats report shows the number of pages crawled each day, kilobytes downloaded per day, and time spent downloading a page.

Bing has a similar tool called "Crawl Control," which provides data on the last 90 days of crawling activity and crawl rates for your site. It also offers the crawl limit number to control the pace at which search bots crawl your site.

Since these tools provide data directly from search engines, you can be sure that they are accurate and up-to-date. Monitor the reports and use the insights to improve your website's crawl budget.

Analyzing server log files

Server log files can give you a detailed view of how search engine crawlers interact with your website. These are text files that contain a record of every interaction between your website and the server. They include information like timestamps, the number of URLs visited, response codes, and more.

Analyzing log files can help you identify any crawl issues, such as pages with high load times or URL errors that could be hindering search engine bots from crawling your site efficiently. 

These files can also provide insights into which pages are most frequently crawled and how often, which gives you a better understanding of your website's overall health. Paying attention to site speed encourages Google to crawl your website faster.

Checking third-party SEO apps

SEO tools like SEMrush and Ahrefs can provide additional insights into your website's budget and how it's being utilized. They offer features like crawl budget trackers, crawl analysis, and more to help you optimize your website for search engines.

These tools are helpful, especially if you're not familiar with server log analysis or want a more user-friendly way to track your number and budget. They also offer other SEO features like keyword research, competitor analysis, and backlink tracking to make your overall strategy more effective.

How To Get Google To Crawl Your Website Faster

To get Google to crawl your website faster, focus on improving site speed and using internal links effectively. These strategies can get Google to crawl faster, thus improving your website's visibility.

Improve site speed

Google has stated that page loading speed is a ranking factor. If your website takes too long to load, it may cause search engine bots to crawl slower and may not have enough time to crawl all of your pages within their allocated budget.

To improve site speed, first, make sure your image sizes are compressed and optimized for the web so they don't slow down page loading times.

Second, use caching to store frequently accessed files on a user's device. This makes it quicker to load content when they revisit your site. Lastly, reduce redirects as much as possible since each redirect adds an extra step for search engine bots to crawl.

Maximize internal linking

Creating a clear and organized site structure with strategic internal links can help search engine bots to better crawl your website. It also helps distribute link equity, which is the value passed on from one page to another through hyperlinks throughout your site. As a result, you make it easier for Google to discover new content and index it faster.

Be careful, though, when adding internal links. Avoid excessive linking, and make sure the anchor text is relevant. Too many irrelevant internal links can dilute the value of your content and affect your search engine rankings. Worse, it can affect how your web visitors perceive your site and negatively impact user experience.

Optimize for mobile

Google has been doing mobile-first indexing for quite some time now. So, if your desktop site is well-optimized, but your mobile site isn't, you may lose out on potential traffic and visibility.

To avoid this, make sure your website is responsive and optimized for smaller screens. Test your website's mobile-friendliness using Google's Mobile-Friendly Test tool and make any necessary improvements. Also, prioritize mobile page speed by minimizing heavy elements and optimizing images for mobile devices.

Use NoIndex and NoFollow tags

NoIndex and NoFollow tags can help you control which pages search engine bots crawl and index, thus optimizing your website's crawl budget. 

For example, you may have duplicate content or low-quality pages that you don't want to be indexed, so using a NoIndex tag can prevent them from being crawled and redirect your budget elsewhere.

However, use these tags carefully as they can also impact how Google crawls and indexes your website. These can backfire when used incorrectly, so make sure to consult with an SEO expert before implementing them on your site. These professionals can assist you in properly implementing these tags to help optimize your crawl budget and improve your website's visibility.

Can I Increase My Crawl Budget?

While you can't directly increase your crawl budget, you can optimize your website to make better use of it. Many factors influence this number, so you must monitor your site regularly to make the most of your SEO strategy.

Have a clear website architecture

A well-structured website helps search engines crawl your pages more efficiently. Aim for a flat architecture where important pages are easily accessible. This means keeping your website's depth to a minimum and organizing content into clear categories.

The best way to do this is to create an XML sitemap to help search engines find all of your important pages. An XML sitemap is a file that lists all of your website's URLs and their respective metadata. It allows search engines to understand the structure of your site and crawl it more efficiently.

Another strategy is to use breadcrumbs to show your site's hierarchy and make it easier for users to navigate. Think of these as a trail that leads back to your homepage.

Breadcrumbs also help search engines understand how pages are related and make it easier for them to crawl your site. You can create breadcrumbs manually or use structured data to automatically generate them. As such, they're an excellent tool for improving your website's crawl budget since they improve both user experience and search engine bots' ability to crawl your pages.

Reduce duplicate content

Duplicate content can waste your crawl budget. This is because search engines can only crawl a certain amount of pages within their allocated time. If your site has duplicate content, search engine bots may spend more time crawling these duplicates instead of new or important pages. This ends up using your budget on pages that don't contribute to your rankings.

To reduce duplicate content, use canonical tags to indicate the primary version of a page to index and avoid having multiple URLs with identical content. Also, set up redirects for old or outdated  URLs to avoid duplicate content issues.

Manage redirects and broken links

Too many redirects and broken links can negatively impact your budget. If search engine bots encounter too many redirects or broken links, they may stop crawling your site altogether.

To avoid this issue, monitor and fix any broken links and minimize unnecessary redirects. Use tools like Google Search Console to find and fix broken links on your website.

Then,  use a 301 redirect to point old or outdated URLs to the most relevant and current page. This helps preserve link equity and also makes sure that search engine bots can efficiently crawl your website without encountering errors and maximize your crawl budget.

Use robots.txt file wisely

The robots.txt file is a tool that instructs search engine bots about which pages of your site they can or can't crawl. You should use this file wisely to avoid blocking important pages that should be indexed. 

Review your robots.txt file regularly to make sure it's not preventing search engines from crawling your high-priority pages and wasting your crawl budget.

Update content regularly

Regularly updating your content signals to search engine bots that your site is current and relevant, encouraging more frequent crawling. However, this doesn't mean you need to create new pages constantly. 

Instead, focus on updating existing pages with fresh information. You can also correct outdated data or add new insights to keep the content valuable and current.

Let's say you have a blog post about the top trends in your industry. As time passes, these trends may change. This is a good opportunity to update your content and provide the latest developments to your readers. It's a win-win situation; you provide value to your audience, improve your crawlability, and optimize your crawl budget.

Invest in quality backlinks

Backlinks from authoritative and relevant websites can also help increase your crawl budget. These high-quality backlinks signal to search engines that your site is valuable and trustworthy and encourage them to crawl it more frequently.

To attract backlinks, create high-quality and shareable content that others will want to link to. You can also reach out to other websites in your industry and offer collaborations or guest posts. Just make sure the backlinks are natural, relevant, and not spammy.

Another way to earn backlinks is by using social media platforms, where you can share your content and engage with your audience. This can increase the visibility of your website and potentially attract more backlinks.

Understanding and Managing Crawl Depth

Another factor that affects crawl budget is crawl depth. This refers to how many clicks away a page is from the homepage of a website.

In simpler terms: it's the level of a page's distance from the main page. 

For example, a page that you can reach directly from the homepage is at a crawl depth of one. The further a page is from the homepage (requiring more clicks to reach), the greater its crawl depth and use up your crawl budget.

Impact of crawl depth on crawl budget

Pages that are closer to the homepage (lower crawl depth) are often crawled more frequently. This is because search engines view these pages as potentially more important or relevant.

On the other hand, pages buried deep within a website, which require a higher crawl depth, might be crawled less often or possibly not at all if the budget is exhausted. As a result, it can take longer for new content or changes to be indexed and appear in search results.

Managing crawl depth for SEO

Managing crawl depth is crucial for optimizing your budget crawl, and it just involves the same strategies above. You keep important pages within a low crawl depth by organizing content logically and hierarchically. 

You can also use internal linking to connect related pages and create an XML sitemap to guide search engine bots to important pages.

Another way to manage crawl depth is by setting up pagination correctly. Pagination refers to the division of long-form content into multiple pages. Search engines may treat each page as a separate URL, which can affect your budget.

When you use rel="next" and rel="prev" tags in the HTML or implement pagination with JavaScript, you can indicate to search engines that these pages are part of the same content and should be crawled accordingly. 

Effective URL Management and Resource Allocation for SEO

Understanding how Google crawls and indexes web pages can make or break your SEO strategy. A key aspect of this process involves the efficient management of URLs and resources. This guarantees that your site's content is readily accessible and prioritized by search engine crawlers.

The role of URLs in SEO strategies

In SEO, URLs serve as the gateway for Google to access and evaluate your site's content. To optimize your site, you must structure URLs in a way that’s both user- and SEO-friendly. 

This would involve using clear, descriptive paths and avoiding overly complex or lengthy URLs. When you do this, you enhance the likelihood of your site being effectively crawled and boost its visibility in search results.

Maximizing crawls for enhanced visibility

For your site to receive adequate attention from Google's crawlers, you must focus on maximizing the number of effective crawls. You can do so by updating content regularly. With this, your site remains relevant and attractive to both users and search engines. 

Additionally, incorporating strategic internal linking within your site can guide crawlers to your most important pages to enhance the efficiency of each crawl session.

If you’re using WordPress, the platform offers numerous SEO advantages through the right themes and plugins. For example, you can significantly improve your site's crawlability and overall SEO performance with plugins designed for SEO optimization. These plugins can help you create SEO-friendly URLs and optimize your meta tags. They can even generate sitemaps, which are essential for guiding Google's crawlers through your site.

One popular plugin is Yoast SEO, which provides comprehensive tools for improving your on-page SEO. It helps in creating content that is both search engine and user-friendly. 

With features like keyword optimization, readability checks, and automatic generation of XML maps, Yoast SEO makes it easier for your content, whether blog posts or landing pages, to be found and understood by search engines.

Allocating resources strategically for SEO success

Effective resource allocation is another critical component of SEO. This involves prioritizing which pages and content types should be crawled more frequently. By directing Google's crawlers to your most valuable pages, you make sure that these key areas of your site receive the attention they deserve in search results.

In terms of advertising, overloading a page with advertisements can hinder the crawl process. As such, you must integrate advertisements in a way that does not detract from the user experience or impede the efficiency of website crawls.

Making the Most of Your Crawl Budget

Knowing and managing your crawl budget can help you optimize your website for search engines and improve its overall performance. When you implement these strategies, you can put your best foot or, in this case, pages out there and boost the chances of your target audience discovering them.

Keep an eye on your crawl budget by monitoring and optimizing your website. Even small improvements in your budget can lead to significant gains in visibility and traffic for your website.

Crawl Budget Frequently Asked Questions

What is crawl waste? How do I reduce it?

arrow-right icon

Minimizing crawl waste is a key part of SEO crawl optimization strategies. Crawl waste occurs when search engine crawlers spend time on parts of your website that don't add value to your SEO efforts. This includes crawling duplicate content, irrelevant pages, or pages with errors. 

When crawlers waste time on these pages, they might miss more important content due to the limitations of your crawl budget.

To reduce this, you must fix broken links, reduce duplicate content, and use the robots.txt file to guide crawlers away from low-value areas. By doing so, you instruct crawlers to focus on the content that matters most for your website.

What is my crawl rate limit?

arrow-right icon

The crawl rate limit is the maximum frequency at which search engine crawlers will visit pages on your website. This limit is set to prevent crawlers from overwhelming your server. As such, it makes sure that your website remains accessible and performs well for users even while search engine bots crawl through your pages.

Search engines determine the crawl rate limit based on how quickly your site responds to their crawlers. If your server is fast and reliable, crawlers may visit more frequently. However, if your server is slow or has a history of errors, the crawl rate limit may be lower to avoid causing issues.

You can sometimes adjust the crawl rate limit through tools like Google Search Console. However, it's generally best to focus on improving your server's performance and reliability. To do this,  consider using a content delivery network, which helps improve site speed and reduce server load.

You can also optimize multimedia, like images and videos, to improve page loading times. Moreover, redirects and caching can help your website respond faster to crawler requests.

Can frequent content updates increase crawl frequency?

arrow-right icon

Updating your website's content regularly can signal to search engines that your site is active and relevant. This can lead to more frequent crawling, as search engines aim to provide users with the most up-to-date information.

However, simply updating content isn't enough. The updates need to be significant and valuable. Adding quality content, fixing errors, and updating outdated information are effective ways to encourage more frequent crawling.

It's also important to promote your updated content through channels like social media and email newsletters. Increased traffic and engagement can further signal to search engines that your content is valuable, potentially increasing crawl frequency.

Is there a difference in crawl budget allocation between new and established websites?

arrow-right icon

New websites may initially receive a lower crawl budget compared to established ones. This is because search engines are still assessing the new site's reliability, content quality, and relevance to users.

As a new website proves its value through quality content, good user experience, and growing traffic, search engines may allocate a larger budget over time. Building a solid backlink profile and maintaining SEO best practices can accelerate this process.

Established websites, especially those with a history of providing valuable content and a good user experience, often have a higher budget. This is because search engines have already recognized their value and reliability, leading to more frequent crawling and indexing.
