Crawl Rate

The number of times Googlebot (Google’s crawlers) can crawl your site in a given time frame without overloading your servers. Google measures the time it has to wait between fetching information from your site to figure out how quickly the servers can work. Your crawl rate will go up if your server responds to Googlebot’s requests quickly, indicating that it can handle more requests. If your server is slow to respond to Google, Google will assume it’s pretty busy and crawl your website less frequently. A faster site provides a better user experience while also increasing the crawl rate (Googlebot perceives a fast site as a sign of healthy, non-overloaded servers). However, according to Google, crawl rate itself is not a ranking factor.
