I think traffic for lists like these is something of a red herring. Small fluctuations for low-traffic sites are almost entirely a result of randomness or sampling error. A better metric would be to divide the companies by traffic into nontrivial traffic(Alexa Rank<10,000) and trivial traffic for the rest. It would require some more research, but it would also be very helpful to separate consumer vs B2B companies and only compare consumer companies on traffic. Many of the companies on that list(including my company MixRank) appear to be doing quite poorly in terms of traffic until one realizes that each visitor to a B2B product is worth orders of magnitude more than a visitor to a consumer product.
