Since Zillow acquired Trulia, all updates to your Trulia listings are now made within your Zillow account.
All of the data/property listings that Trulia has comes directly from Zillow.
Most important is to make sure that your profile is 100% complete on Zillow and also insure that your listings are connected to your profile.
In 2019, Zillow and Trulia are the number 1 and 2 top real estate websites for online searches.
Whether you love or hate them, it doesn’t matter. Because they dominate real estate searches you must make sure your profile and listings are all squared away.
