How Googlebot visits your site

Accessing Site by Googlebot: Googlebot shouldn’t access your website more than once every few seconds on average. It run simultaneously by thousands of machines located near the sites to improve performance and scale as the web grows.

Googlebot can crawl the first 15MB of an HTML file or supported text-based file. After the first 15MB of the file, Googlebot stops crawling. Other web crawlers may have different limits.

To find out how often Googlebot visits your site and what it does there, you can dive into your log files or open the Crawl section of Google Search Console. Googlebot crawls from IP addresses in the United States available in JSON format.

Note that Google does not share lists of IP addresses that the various crawlers use since these addresses change often. To find out if a real Googlebot visits your site, you can do a reverse IP lookup.

Spammers or fakers can easily spoof a user-agent name but not an IP address. You can verify if a web crawler accessing your server really is a Googlebot. There are two methods for verifying Google’s crawlers viz. Automatically and Manually.

You can also use the robots.txt to determine how Googlebot visits your site. There are better ways to prevent your site from being indexed.
