Never, ever, EVER repeat content on your website. Major search engines HATE duplicate content and will, at best, ignore it or, at worst, punish you for it. Even large sites have been penalized for having the same article posted more than once. If you must post similar content, entirely rewrite it to be original.
To optimize your search engine results you should always try to use the most “common terms” related to your search. For example, if you are looking for someone to fix your toilet, you should search for a “plumber” instead of “someone to fix your toilet”. Also, do not type in full sentences. Try to decrease your search to a few terms.
If your site serves a market or audience with established ezines, contribute articles and other information with backlinks to your site. Ezines will be saved forever and they can be accessed forever. Someone may find you years later!
