I am not very sure what is the purpose of this review, because it's not exactly a review, I just want to say if you are using a lot of rank trackers you are going to get crazy So I will present you screenshots from 8 rank trackers, both web-based and desktop based for 3 keywords, they are presented as "kw1" "kw2" "kw3" on the screenshots, they are not in order on all of the screenshots, so be careful The rank trackers are: Traffic Travis, Rankerizer, CuteRank, SerpAttack, Serpfox, Serpbook, Serpscan and MicrositeMaster, so 4 web-based and 4 desktop based. So let's start. Oh, maybe it's good to mention if there are paid/free. All of them are free but they have limitations, only Serpbook is paid but the trial is 0.95$ so I would consider it free. Traffic Travis Rankerizer CuteRank SerpAttack Serpfox SerpBook SerpScan MicroSiteMasters As you can see the rankings shown can vary, actually the difference is between the web-based and desktop based rank trackers. I did not use USA proxies for the desktop based programs. As I've mentioned this is not typical review, because I am not going in details explaining what I like and I don't like about each one of them. Which one is the most accurate, I wish I knew... but I don't. My advice is stick to one or two. I personally like the most SerpBook and Serpfox, but I would prefer Serpbook, because the rankings are updated on every 2 hours and Serfox updates the rankings on every 8-10 hours. But Serpfox has better graphics in my opinion. Cheers !
