3 types of Search Engines

1.       Spiders
The search engine sends out a ‘spider’ or ‘robot’ that records all the text on your website. That text is then indexed in a database, categorized by keyword, and given a relevancy ranking. A higher relevancy ranking makes your pages appear higher when the search engine returns results to a visitor.
a.       Main Engines – Google, Yahoo, MSN
b.      Benefits – These are the Big Three and they cover 95% of all search engine traffic. Concentrate your efforts here and forget about the little guys.

2.       Directories
Directories have websites submitted to them for review. The best directories are reviewed by hand and disallow affiliate sites or sites with little or no content. Most directories get very little traffic but, since the included websites are reviewed for quality, the Big Three consider them a good source to find new websites. Getting listed in directories is the most common way to build link popularity.
a.       Main Engines – Business.com, DMOZ.org, GoGuides.com, JoeAnt.com, Gimpsy.org
b.      Benefits – While these engines don’t get a lot of traffic other search engines use their results. Spider engines like Google consider directories to have high quality content and often index the directory’s additions.

3.       PPC – Pay-per-click search engines sell ranking by keyword in an auction format. If you want to have a high ranking you simply bid more for that particular word. These results appear at the top or side of the regular listings.
a.       Main Engines – Yahoo Search Solutions and Google Adwords. Shopping PPCs  or price comparison engines, include Shopping.com, Nextag.com, and Pricegrabber.com.
b.      Benefits – Getting listed in a Directory or Spider engine can take weeks or months and getting a good ranking can take up to a year of trial and error. With a PPC listing you’re up and running in under a week and you can get exactly the keyword and ranking you want.
