Keyword selection is another important factor used in SEO and driving potential customers to your site.  When setting up a website it is important to select 20 or 30 keywords that could be used to describe your business by potential customers that are searching for your products or services.  A good tip is to also look and see what your competitors are using as keywords when describing their products. 

Using a string of keywords either two, three, or four is also an effective way of increasing the chance that the potential customer will find your business specifically, as it narrows down the field of potential websites increasing your rankings on a search engine’s results page.
