1. Your key words need to be found in the body of your document. If they are truly key words they will appear at least 3% of the time on your page.
2. Try and focus on getting traffic for relevant key words on your web site that do not have as much competition as others. For example, if you want to get a person to your web page when they type in the single search term “health”, you are going to have a tough time getting page 1 results. However, if you are offering manicures, you might want to attract people looking for information about “fingernail health”, which would be far easier. (A good test is to go to your favorite search engine and type in your key words and then look at the number of results displayed. The fewer there is, the easier it will be for you to get good results for your relevant key word searches.
3. You need to have a minimum of 100 words of text on your pages. Content is king.
