Why Is Googlebot?
Googlebot is a web crawling software. Search bots (also known as spider or webcrawler) collects information about the web page used to supply Google Search Engine Results Pages (SERP).
webcrawler uses algorithms to determine which sites to browse, what rates to browse, and how many pages to bring. Googlebot starts with a list generated from previous sessions. This list has then been augmented by the sitemaps provided by webmasters. This software crawls all linked elements in webpages, notes new sites, updates to sites, and dead links. The information collected is used to update the index of Google's web.
Googlebot makes webmasters an index within their defined limits in robots.txt files. A webmaster should keep pages hidden from Google Search, for example, he can block Googlebot in the robots.txt file in the top-level folder of the site. To prevent Googlebot from following any link on a given site's page, it can include the nofollow meta tag; To prevent bots from following the different links, webmasters can automatically add rel = "nofollow" to the link.
By showing a user-agent Googlebot, a site's webmaster can track visits to computers every few seconds on google.com. Generally, Google tries to index the excess of a site because it can do without affecting the bandwidth of the site. If a webmaster realizes that Googlebot is using a lot of bandwidth, then they can set a rate on Google's search console homepage, which will remain effective for 90 days.
Presenting at the 2011 SearchLove conference, Josh Giardino claimed that Googlebot is actually a Chrome browser. This would mean that Googlebot not only has the ability to browse pages in lessons, as do crawlers, but also run scripts and media as other browsers do. That capability can allow Googlebot to search for hidden information and do other things that are not accepted by Google. Giardino said that Googlebot may be the root cause that the company created Chrome.
