Think of the right keywords as the Open Sesame! of the Internet. Find the exactly right words or phrases, and presto! hoards of traffic will be pulling up to your front door. But if your keywords are too general or too over-used, the possibility of visitors actually making it all the way to your site - or of seeing any real profits from the visitors that do arrive - decreases dramatically.
Your keywords serve as the foundation of your marketing strategy. If they are not chosen with great precision, no matter how aggressive your marketing campaign may be, the right people may never get the chance to find out about it. So your first step in plotting your strategy is to gather and evaluate keywords and phrases.
