I'm looking to try new SEO ranking software. We've used ranktracker in the past but would like to try some alternatives. It must have features specifically designed for use with clients - for example setting up reporting for individual clients that runs automatically and is sent directly to the client. Our clients aren't SEO clients as such, they're our advertisers and we have an optional SEO rank tracking service.
I'm not looking for free solutions (although not opposed to them), but would prefer a one time cost solution rather than a recurring thing.
