Googlebot is software created and used by Google to collect material from the Internet to create a search index for the Google search engine. This term refers to two types of different scanners at once: desktop computers and mobile devices.
The robot, using the results of previous sessions, analyzes each individual site and replenishes the database with new files from the Sitemap. The crawler also scans pages for third-party links and adds them to the list of sites to crawl.
Site administrators can interact with this bot and show it the necessary information in different ways, or even refuse to check it all together.
If certain lines of code in the site parameters allow Googlebot to access a web page, it initially saves it in Google’s index. This is how the bot scans the global web.
Google is constantly updating the program by adding computing power. At the moment, the system is spread across a huge number of data centers, so it can scan tens of thousands of web pages at the same time.
