I came across numerous articles and comments about how to track PR and which specific tools SEO- PR specialists use. I am interested to get your point of views about the 3 following tracking tools:

1/Radarfarms

2/BurrellesLuce( seems to be the most used - but American!)

3/PRTrak offered by VMS (MORE INFO ON: http://www.instituteforpr.org/resear...nd_evaluation/

Does anyone know anything about these tracking tools?? Which one could be the most appropriate for Online PR and multilingual track???:confused
