I think you (as many do) have a misunderstanding of Google. Google is NOT the traditional search engine that most optimizers were used to (pre-google). Ranking is not based on metatags or keywords and so on. Google ranking comes from number of times your website is hit by links from other sites. It is more a popularity contest. If you want to raise your google ranking try to get your site linked off other sites (your chamber of commerce, agencies within your market areas, other companies) and so on!
