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 the 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.”
