Comscore, as anyone who has used it will attest does not give a very reliable report on the traffic numbers - Google Analytics does the job for us. But how reliable is it with respect to studying competitor growth trends? When Comscore reports that company A has dropped more than company B - does it make sense to assume this relative performance to be true with actual traffic numbers as well?
