How Does a Search Engine Index Web Pages?

There are four parts to an engine that you need to know about for optimization purposes:

• The spider is a program that goes out across the internet, looks for and gathers up web pages.
• The database is where the spider will store the pages that it finds.
• The search engine website is where searchers go to pull up information from the database.
• The algorithms are programs that determine which sites will come up when searchers type in a query at the search engine website.

There are two ways that your site can get into the database:

• The spider will automatically find your site from a link on someone else's site which is the path I recommend if you can get one or more quality inbound link(s).
• You submit your URL so that the spider will come out and find it.
