My ROI on any paid zip codes was zero. I have closed several profitable transactions as a result of my contribution to providing value to the consumer.
The double edge sword for Trulia is that in order to stay in business they must have paid advertising. This comes from Agents, RealtyTrac, and others. The problem is that we must educate the consumer that the foreclosure offerings on RealtyTrac is a source of income for RealtyTrac. Also, Trulia allows the general public to advertise rentals which are mostly spam and and take advantage of the consumer. So we have to educate the consumer on that as well. The education on RealtyTrac and Rentals are not income producing for the agent, but helps rank the agent, and is a public service for the consumer.
Now there are tons of spammers posting in questions which have ZERO to do with real estate, sports or what ever the links are doing to scam, spam or otherwise take from the value here.
So with that bandwagon rant. I still support Trulia, I just don't pay. I want to protect our industry and that is a fine line.
