While indexing websites, search engine crawlers emphasize on indexing web pages without impacting the experience of the website visitors. They adhere to the crawl rate limit to collect information from a website at the maximum fetching rate. The number of URLs on a website crawled by search engine crawlers like Googlebot on a single day varies based on a number of factors including the size of the website. The website owners and webmasters can easily make Googlebot crawl additional URLs on a website by increasing crawl budget.
According to Yoast.com, “Crawl budget is the number of pages Google will crawl on your site on any given day. This number varies slightly from day to day, but overall, it’s relatively stable. Google might crawl 6 pages on your site each day, it might crawl 5,000 pages, it might even crawl 4,000,000 pages every single day.”
However, the definitions of crawl budget differ across websites. Google advises webmasters not to focus on and worry about crawl budget. But the webmasters cannot improve the search engine visibility and ranking of websites without focusing on crawl budget optimization.
Unlike other website statistics, crawl budget cannot be measured and expressed as a single number. The webmasters can use crawl budget as a parameter to measure search engine ranking and performance of a website based on two important factors – how many pages search engines index from the website and how frequently search engines crawl web pages from the website.
As noted earlier, major search engines like Google recommends webmasters to ignore crawl budget while implementing search engine optimization (SEO) strategies. But Google clearly mentions that crawling and indexing of a website is impacted by a number of factors – low quality content, on-site duplicate content, soft error pages, hacked pages, complex navigation structure, and infinite spaces.
The webmasters cannot get regular search engine traffic to the website without resolving the issues that make it difficult for search engines to index and crawl important web pages on the website quickly and efficiently. While implementing a SEO strategy, they can make it easier for search engines to crawl more web pages by increasing crawl budget consistently. There are a number of reasons why the webmasters must focus on crawl budget optimization as an important aspect of SEO.
The webmasters add new web pages and update existing web pages regularly to keep the website visitors engaged. But the potential visitors cannot see the new pages and updated pages unlike search engines index and crawl them. The webmasters can make the search engines index all pages on the website simply by focusing on increasing crawl budget.
Many websites these days are developed with thousands of web pages. Likewise, many websites allow visitors to read content and information in their preferred languages. While indexing a website, crawlers adhere to the crawl rate limit set of search engines like Google. The webmasters can make the crawlers index all web pages on a large website quickly by optimizing crawl budget.
Google recommends webmasters to update website content frequently to deliver relevant and up-to-date search results. But the changes and updates made to the website will not reflect on search results if the search engines do not crawl the web pages efficiently. Crawl budget optimization helps webmasters to make the changes made to the website appear on search engine results pages.
While implementing SEO strategies, webmasters focus on adopting the latest search engine guidelines and implementing white hat SEO techniques. But the webmasters cannot leverage the white hat SEO techniques fully without optimizing crawl budget. They must focus on crawl budget optimization to make the search engine index all web pages on the website before applying various SEO techniques.
While crawling a website, search engines refer to its Robot.txt file to understand the URLs that can crawl and can’t crawl. The webmasters can easily make the search engines crawl all URLs on a website by allowing them to crawl all important pages on the website fully and freely. The unrestricted access will make the crawlers gather information about the pages to be crawled. However, the webmasters must keep the Robots.txt file up-to-date using a robust website auditor tool.
As a series of redirects, redirect chains redirect the search engine crawler from one page to multiple pages. Hence, search engine crawlers find it challenging to crawl all URLs on the website in a short amount of time. The webmasters can easily optimize crawl budget by keeping the number of redirects in the redirect chain low. It is also advisable to reduce the number of redirects in the chain two. The decrease in number of redirects will make the search engine crawler new and additional URLs quickly.
A website’s crawl budget is directly impacted by HTTP response codes ranging from 400 to 599. Also, specific error pages like 401 and 410 impacts the crawling budget. While implementing crawl budget optimization, the webmasters must focus on indentifying and fixing both client errors (400-499) and server errors (500-599). They can easily identify the client and server errors using a widely used website audit tool.
While crawling a website, the search engine crawlers consider and treat each URL as an individual web page. Hence, crawlers need additional time to crawl websites with multiple URLs. While optimizing crawl budget, the webmasters must focus on conveying URL parameters clearly to the search engines. They can further use canonical URL tag to eliminate content duplication issues when multiple URLs display similar and identical content.
The sitemaps convey important information about a website – web pages, images, videos and other files – to the search engines. The webmasters often ignore the significance of updating the sitemap each time each time the website is updated. When the sitemap is not updated frequently, the search engines do not crawl the new URLs. The webmasters can easily optimize the crawl budget by keeping XML sitemap up-to-date. They can use widely used WordPress SEO plugins like Yoast to create the sitemap on the fly and update the sitemap automatically.
Many websites these days deliver information and content in multiple languages. The search engine crawlers often fail to distinguish between localized pages and universal pages on a website. While implementing crawl optimization, the webmasters can make it easier for crawlers to identify and distinguish the localized pages using hreflang tags in the header. The hreflang tags will make the crawler distinguish between region-specific and region-specific web pages while crawling the website.
While indexing a website, search engines often ignore thin content pages and duplicate content pages. The webmasters cannot increase crawl budget without removing all duplicate content from the website. Likewise, they must prevent the search engines from indexing the thin content pages. At the same time, it is also important for webmasters to add value to the thin content pages by replacing the short form content with long form content.
Often ecommerce websites make it easier for customers to find more relevant products by supporting URLs with parameters. But the number of URLs increases significantly as the customers use a wide variety of parameters. The increase in the number of URs impacts the crawl budget directly. While implementing crawl budget optimization, the webmasters must prevent the search engines from crawling the URLs with parameters by adding nofollow attribute and making changes to the Robot.txt file.
While implementing crawl budget optimization, the webmasters must separate indexable pages from non-indexable pages. They must remember that the indexability of a website is impacted when it contains more non-indexable pages. Hence, they need to indicate the error pages, redirects and non-indexable web pages clearly to the search engine. Also, the webmasters need to ensure that the indexable web pages are not referencing to the non-indexable web pages. They can easily distinguish the non-indexable pages by making changes to the Robots.txt file.
While exploring ways to increase crawl budget, the webmasters must focus in enhancing the website’s online reputation by building high quality external links. Despite frequent search engine algorithm changes, external link building has remained an effective SEO technique. The webmasters can use backlinks as a robust tool to convey the popularity and reputation of their websites to search engine crawlers. The webmasters must implement external link generation strategy to make the search engine crawler visit the web pages frequently and improve the crawl budget consistently.
Often crawl budget is impacted hugely by a number of crawl errors. There are a number of reasons why search engine crawlers visit and crawl certain websites. The webmasters can easily identify the crawl errors using Google search console. Google search console highlights the crawl errors by producing index coverage report. The webmasters can refer to the index coverage report to understand if the submitted pages have crawl issues. Also, they can use the tool to request Google to index and crawl the web pages by sending an email.
The loading speed of web pages directly impacts their search engine visibility and user experience. Also, the website’s loading speed affects the crawling budget by preventing the search engine from crawling more pages quickly and efficiently. Hence, the webmasters can easily optimize crawl budget and improve the website’s search engine visibility by making the web pages load faster. They must use online tools to measure the loading speed of web pages frequently. Also, they must keep in place a strategy to speed up the web pages.
Major search engines like Google do not index websites frequently if they are not secure. The webmaster must remember that security issues impact the website’s credibility and decrease crawl budget. They must explore ways to make Google trust the website by adhering to the latest search engine guidelines related to web security. For instance, Google recommends website owners to boost website security using HTTPS instead of HTTP. However, the webmasters must leverage security tools and services to monitor website security continuously and resolve security issues proactively.
The most effective way to increase crawl budget is to publish fresh content regularly. The search engines index and crawl websites that post fresh content on a regular basis. In addition to removing duplicate content, the web masters must explore ways to keep the website fresh. They can easily keep the website fresh by posting new blogs and adding new web pages. However, the webmaster also have the option to increase crawl budget by modifying or updating existing content and getting backlinks from new websites.
As an important concept in SEO, crawl budget impacts the number of URLs on a website crawled by search engine crawlers like Googlebot. Google does not consider crawl budget as a key ranking factors. Also, it advises webmasters to ignore crawl budget. But no webmaster can divert more and regular search engine traffic to the website without optimizing crawl budget. Hence, they must focus on crawl budget optimization while implementing and updating SEO strategies.
