I’ve just joined as an internet marketing intern in a local company. My supervisor advised me to learn SEO. I’ve started reading stuff a day back and I’m confused with search engine spiders, crawlers and robots. Please explain me in easy words that what’re all these?

    Search engines work by sending out what are called spiders, crawlers, or robots. Whatever the name used they are essentially just computer programs that follow web links looking for pages to index. When they get to a page, they take a sort of picture of the page, indexing the information on it, and integrating it into their giant database of millions of websites. When you type a keyword into the search engines looking for websites with content on that topic, in a split second they go through billions of web pages that the spiders and robots have visited. Web pages are typically revisited every few weeks by these programs.
