Next, we learned what is search
engines. Basically, a search engine is
a software program that searches for sites based on the words that you
designate as search terms. Search engines look through their own databases of
information in order to find what it is that you are looking for.
Search
engines automatically create website listings by using spiders that
"crawl" web pages, index their information, and optimally follows
that site's links to other pages. Spiders return to already-crawled sites on a
pretty regular basis in order to check for updates or changes, and everything
that these spiders find goes into the search engine database.
