I am unsure about advertising listings / ROI as we are an exclusive buyers agency with nothing to sell but my guess is the exposure to more buyers is positive (trulia ranks high on google).
People do tend to choose realtors based on friends / family suggestions and word of mouth. Buyer's should still beware and make sure they understand that - even if "referred" - in this business unfortunately not everyone's interests are aligned and 9 times out of 10 it is the buyer who ends up losing the most.
Interesting question and look forward to seeing other responses.
I found my broker through word of mouth referral from a co-worker and seemed to think most relatively established agents found most of their high probability of closing/intent to buy clients through word of mouth vs. online leads, but I could be totally wrong.
Just curious if agents are actually converting leads through these sites. It seems like buyers are using these sites + Redfin, MLS, etc. to research properties but are finding brokers through friends/family v. choosing one through these sites. Again, i could be completely off as my experience may be different from others.
If you are an agent - there is Agent-to-Agent option for posting.
I doubt buyers or sellers care for our ROI.
The best way to see what's working and what's not is to try and track the results.
If something does not work, then re-group and try something else.
Each area is different too. I notice that there are mostly buyers, no sellers through
the channels you mentioned.
Hope this helps,
