Zillow Rental Manager does not add significant value beyond the sites owned by Zillow. It also makes for a very poor listings page, as it is Zillow's experience and not yours.
Therefore, we recommend that you Turn Off Zillow Rental Manager Listing Syndication and Transition to ShowMojo.
If you do have your own website, you should also Optimize Your Website for ShowMojo.
Finally, if you really believe you need to keep Zillow Rental Manager syndication running, then be sure to Send All Zillow Rental Manager Inquiries to ShowMojo.
