As an ad agency I've used a lot of seo tools and this one gets high marks!! The price is incredible and the information it provides is awesome. I ran across an issue that the platform that some of my sites were built on did not work with spidernow. I explained the issue to one of the Partners at Spidernow and they got right on fixing the problem. Really something I didn't think would happen. I'm super impressed with their customer service. I recommend this app to anyone who needs to seo their website whether its one site or one hundred. It's a great piece of software.
