Is it listed on Zillow? Expect responses from ppl to run a landing page then chat bots etc etc. Create 2 campaigns using the same ad, going to the Zillow Page. PUT the price in the ad. One engagement campaign, the other a traffic campaign(cause you can’t pixel Zillow. ). 100% without a doubt you’ll see the zestimate go up, saves on the page etc. I’d spend $50/day
