Zillow (NASDAQ: Z) has become the place where most people start their homebuying journeys, with over 195 million unique visitors visiting the site on a monthly basis. For real estate agents, advertising on the platform can generate a host of new leads for customers, leads that until earlier this year they had been willingly paying up for.
But growth ground to a trickle in 2019, and though the situation seems to have stabilized in the third quarter, with revenue rising 5% to $241 million, Zillow may have another problem that could cause this once-lucrative revenue stream to come undone.
