Do You Understand The "Comment Line"?

Sticking to the topic of search engines, here's a tip that while not really effective anymore on the major search engines may still have some benefit on some of the second tier search engines.

The <!...comment line...> Are you aware that anything entered into your webpage that starts with an "!" is invisible to the viewer? Any tag that starts with "<!" is called a 'comment tag'. You can put pretty much anything you want into a comment tag although they are most widely used for placing extra keywords, or just another place to have your main keywords be seen by a search engine. The tag would look something like this: <!-- make money, business opportunity, cashflow, online marketing, make more money -->
