I have been using WCA blissfully unaware of the impending doom! As it gives me what I need in terms of SERPS when searching for hotels and restaurants in towns and cities, even without the Commercial Intent feature which I do not need anyway. But I do hope that Jon will come with with an alternative to WCA in due course.
I am not an affiliate but I also use SEORankfinder.com by Chris Ramsey which gives the position, title and description from Gxxgle for a URL and keywords also Cherry Picker Software.com which was a freebie and also Traffic Travis (Free-Version 3) features Page Analysis amongst other useful tools. Version 4 is being launched on May 2nd
I had a look at Majestic SEO before and it looks good but I decided to stick with WCA!
I respect Jon and his integrity as a marketer and when I get an email from Jon I know it will be another GEM he has come up with! Like many others, I follow Jon Leger!
