Certain spiders then read the information in the tags as a way to help them index the site. See how easy and lucrative it is to advertise your auto products and services on the Information Superhighway. First place a number of related links on your site, and then contact those sites asking for a reciprocal link. You'd be surprised how many people are willing to do this. Once you are in an engine, check your site at least once a week.

Pages disappear from catalogs. Links go screwy. Watch for trouble, and resubmit if you spot it. The engines have grown smart enough to realize some sites only change content once or twice a year, so they don't visit regularly. Resubmitting every month or two will ensure that your site's content is kept current.
