IDX means Information Data Exchange. Any MLS that exchanges information with a real estate technology company is engaged in an Information Data Exchange. Any company I have put into this category is there because the main selling feature of their website packages is the search experience. The secondary services they offer often include lead generation, which makes understanding the difference between real estate website providers a little difficult. IDX/Search vs Lead Generation Companies One main way to define a true lead generation company is the way that they support the website. Both InboundREM and BoomTown provide end-to-end solutions where the only task the client has to do is manage leads. Boomtown and IREM both require some learning, but this is a managed process with resources dedicated to stepping you through the process. ALL other providers make the client LEARN how to get leads from their website. If you fail to follow these companies’ tutorials (if there are any), they will promptly tell you the reason you’re not getting leads is your incorrect use of the website. IMO, a true lead generation company takes all that guesswork away from the client. The only service education should be educating real estate teams on how to access and work leads. A quick way to identify how RICH a real estate IDX website search experience is supposed to be is the price. Prices range from $0-5000 for setup and monthly costs of $56-1000.
