I've read so many different things about SEO to do's and not to do's I can't get it straight. I see Adrechelle built your website , she should be able to answer any questions you have about SEO on your site.
When reading up on SEO for my website I found that it's not so much what you have in the meta tags anymore , it's more of what your content is on your website. How it all works, I have no idea and if I do figure it out I'm sure it will all change tomorrow.
Sorry I could not help.
Edit: Maybe I can help a little about how it will help you.
If you website is SE friendly then you should be hitting on the first page of a google or yahoo search in your area , my area would be "carpet cleaning bay city" . I come up first on google. Now in my website I have some key words like Carpet Cleaning | Bay City | .
But ask Andrechelle , she nows her shtuff
