I have done some work for one of my clients and I greatly improved their Google Ranking (it was kind of cool because I wasn't really trying). I would like to track their overall rankings on the web so that I can see how much it improves over time. I have google analytics running and run the "Site" and "links" searches through Google often, but would like an overall picture. Is there a site that can track all of this? If it works out good I would like to offer more SEO services to my clients and would like to have tracking to show them. Thanks everyone
