• How spiders work. Search engines gather data regarding a single website by sending an electronic spider to visit the site and copy its content that is stored in the search engine's database. Commonly identified as 'bots', these spiders are designed to follow links from one page to the next. As they copy and absorb content from one page, they record links and send other bots to make copies of content on those linked pages. Starting in the top left hand corner, a spider will read site content line by line from left to right. In case columns are used (as they are in most sites), spiders will track the left hand column to its end before moving to central and right hand columns. If a spider encounters a link, it will record that link and send another bot to copy and record data found on the page the link leads to. The spider will proceed through the site until it records everything it can possibly find there.
• How search engines figure out what pages relate to which keywords and phrases.
