If the product you are selling is hvac service chapel hill, then you want to hire a good content writer to write pages on your site that use a set of proper keywords that will drive customers to your site. It is a given that you are probably not the only HVAC business selling your services online, so it is important to be creative with keywords. Instead of using HVAC services as the main keyword, you may choose to use "HVAC services in California," or "cheapest HVAC services available." A keyword does not have to be a singular word, it is a word or phrase that will drive traffic to your website when a customer searches that product online.
