A great source of industry info is WAV Group. Here is a relevant data piece on IDX.
>>This is a rather obscene notion, but sometimes the best way to innovate is to ask a bunch of questions about the status quo. For brokers and MLSs to innovate, they need to question the effectiveness of IDX. I would not question its value. Rather, I believe that it has uncompromising value to MLS participants and subscribers. I question how we can make it more valuable. Perhaps it is time for a reboot. A reboot is a process where you turn something off and turn it back on to stop routines from running that undermine the operation of the machine. Some Background Here is a little background on how the consumer’s online behavior is measured. This is important to understand because if you don’t, you will take some consumer statistics for facts when they really are not. For example, according to ComScore, 1 in 3 consumers visit the top 3 real estate websites: Zillow.com, Realtor.com; and Trulia.com. The education about this stat is in the statement “according to ComScore.” You see, ComScore only counts using survey data. They put a tracking cookie in a bunch of consumer browsers and watch how they behave. Using a little bit of data, they estimate a lot trends. The second thing that you need to know about ComScore is that they only track the top 100,000 websites in America. That means that they only track a thin number of real estate websites. Only huge broker, franchise, and a couple of MLS consumer sites even get counted. Taken out of context, ComScore data would yield that IDX is useless to most agents and brokers because nobody goes to those websites. That is incorrect. ComScore is not counting IDX sites. In truth, nobody really is. Reboot Idea Number One – Start Counting What is really great about IDX is that permitted use is structured in a way that benefits all participants in the program. There is an agreement. What if that agreement required that you install a tracking code on every site that displays IDX data. You have seen reports from portals about the number of times that a listing appeared in search results and the number of times a listing detail page was viewed. If that data were counted for every IDX site in every MLS across America, I would expect that the total amount of traffic would be very different than what ComScore is […]<<
