These little robots most likely to your website and also "review it" in much the exact same means as a human does, delegated right, leading to base. What these robotics locate they bring back to the "mothership," the internet search engine database. If Googlebot discovers your website about kitties, it will certainly report the site, its location (URL), its materials, and so on to Google's data source where it is saved.

All the searches you do hire data currently in the internet search engine's data source, not from a brand-new search of the whole internet.
