What is Google Bot / crawler / spider? why is important in SEO?

Googlebot crawls web pages via links. It finds and reads new and updated content and suggests what should be added to the index. The index, of course, is Google’s brain. This is where all the knowledge resides. Google uses a ton of computers to send their crawlers to every nook and cranny of the web to find these pages and to see what’s on them. Googlebot is Google’s web crawler or robot and other search engines have their own.

Many of uses different platforms which are already griped by the bots so placing the link there would crawl faster with better rates over !
