This is the single most important tip I can give you. This is as it should be. I think this is ridiculous and if you're serious about running a legitimate internet business you'll find that, in the long run, you'll be much more successful by attracting people to your page that are truly interested in information about you and your product. So before you begin a search engine listing, anywhere, Remember that you should choose the key words that your customers would use to try to find an honest and reputable business page that really would provide them with what they're searching for. Then make your home page relevant to those key words.
First impressions are very important.
You not only want people to see your site listed, you want them to click on it and go to your site. So here is a simple little trick that works like a charm. Although there are hundreds of search engines each with their own policies and procedures, most engines search by relevancy. In other words, the more a site pertains to the key words the better chance it will come up first. So try to include your key words in your text as much as possible without being redundant.
