Hi Friends,

Spiders, Bots and Web-crawlers all mean the same thing. They are automatic programs which go through every website.
They perform their actions in different steps:
First, they crawl any site. (It takes around 4-weeks on average to crawl the entire web).
They download the content on their specific servers.
They index the content( with the help of other tools) according to Keywords.
They are very complex, programs with proprietary algorithms.
