There's more than one way to get internet leads. The long and short of it is that they all cost money, and they are all similar in quality. My realgeeks site: phoenixrealestateandhomes dot com is fetching 70 - 110 leads per month all from organic search.
Not all real estate websites are alike
The truth is that most real estate websites do nothing more than act as an invisible billboard. The realgeeks websites have awesome search functions that visitors love (much better than Zillow). The capture features on the RG sites are what makes agents like me rave about the platform. There's nothing that compares on the internet, and that's a big deal when you are competing for traffic in an ultra-competitve market like Phoenix metro.
