Search engine optimization - or SEO as it is abbreviated - is a science in itself. Search engine optimization is about how to get search engines like Google and Yahoo to "like" precisely your page in relation to what you want your customers to find you and why it is important that your website is search engine friendly.
If you are eg. plumber with the main customer circuit in Yourcity, you might want your potential customers to find you if they search for "plumber Yourcity" in Google. You can even test: Search on Google with a keyword for your services (such as Plumbing Yourcity): If you don't show at the top 3 pages of Google, is a small chance that those who are searching for your offer will find you this way. Then you may want to consider search engine-optimization of your pages.
