I'm not sure if the people who bashed this place expected some sort of miracle, but I have a site with lots of links and I've been using Enterurl.com for about a year now and my site is listed in a lot more place and have gained in search engine ranking since I've been using their service. I tried two other places and got no results, but Enterurl has given me measurable results. I recommend the place. Their sales guy took the time to recommend some changes in the meta tags on my page to help out. I like them.
