Hi Kim: Well, you've seen that responses to your question run the gamete from not doing anything to making big changes. Unfortunately, a lot of people think they know about
seo who don't know much at all. That's just life. There are all kinds of people of course in the world.
From experience with
seo over a number of years I can tell you this: Yes change the url to a really good name-- something that describes your business well and make it as short as possible. A check of your site's domain name in the whois directory shows it was registered in 2004. So that will help with the new site since the old one has already been through the aging process. Keywords are good but not necessary. Learning or hiring a good
seo are the key to make your site successful with excellent content of course. Look my sites up in G and you'll see how they rank for yourself for proof.
Whatever you do when you make a change make sure to do a 301 redirect from the old name to the new site. If you use the same site it will take a while for the se's to recognize the change. So be patient and work on more content to improve your site for the user's experience. There are 2 forms of
seo-- on site and off and you need to do both to be successful. Good luck with whatever you do!
