I'm not sure where REA and Fairfax get their figures from, but RNT get there figures from "AC Nielsen Market Intelligence Duplication Report May 2015".
They may use the same source, but I reckon these figures could easily be fudged up to make it look good.
I've probably viewed the rent site about 1,243,983 times myself - Lol.

The biggest challenge that Rent has to overcome, which makes them a higher risk stock, is moving free listing agents over to paid subscriptions. Currently most agents are signed on for free - rent is going to "upgrade" them over to paid subscriptions. IMO they will nail this goal, due to the viewings rent is getting, even before commercialisation, but it will be a gradual process so as to not lose business.
