Zillow vs. Redfin vs. Realtor.com vs. Google: Where Agent Reviews Come From
Same agent, six different review counts. Here's why, and which ones to trust for what.
Look up one agent on six sites and you'll get six different pictures. That isn't the agent being inconsistent. Each platform collects reviews in its own way, and the way it collects them decides what the number means. Here is how to read each one.
Zillow
Zillow reviews are submitted through the agent's profile and Zillow asks the reviewer to describe the transaction. Agents send review requests to clients directly, so the reviews skew positive but are almost always from real clients. The profile also carries a sales history pulled from listing data, which makes Zillow the best place to check whether reviews and sales line up. Strength: volume and transaction detail. Weakness: agents control who gets asked.
Redfin
Redfin publishes reviews for its own employed agents and for partner agents it refers clients to. Those reviews are collected after every Redfin transaction whether the client is happy or not, which makes them less filtered than most. For agents who don't work with Redfin, there is nothing there. Strength: less selection bias. Weakness: covers only part of the market.
Realtor.com
Realtor.com reviews come through its agent profiles and its own review-request tools. Counts are usually lower than Zillow's for the same agent, and the profile includes recommendations, which are shorter endorsements. It also shows listing activity. Treat it as a second source that should broadly agree with Zillow; if it doesn't, ask why.
Google reviews are attached to a business profile, which for an agent may be their own name, their team, or their brokerage office. That is the main thing to check: a brokerage with 400 reviews tells you nothing about one agent inside it. Google is the easiest platform for anyone to leave a review on, so it collects more complaints than Zillow does. Strength: the unhappy clients show up here. Weakness: figuring out whose profile you are looking at.
Yelp
Yelp filters reviews aggressively, and reviews from people without a Yelp history often end up in the "not recommended" section. Counts are low for most agents outside big metro areas. When Yelp reviews exist, read the filtered ones too; they are often the most candid. Strength: candor. Weakness: thin coverage.
Experience.com and other survey tools
Some brokerages send every client a survey through a third-party tool and publish the results. Because the survey goes to everyone, the response rate and the distribution of scores are more meaningful than a hand-picked testimonial page. If an agent quotes a rating from one of these, ask how many surveys it is based on.
The agent's own website
Testimonials on an agent's site are chosen by the agent. They are useful for seeing what kind of client the agent wants to attract and which neighborhoods they claim, not for judging service. Sales volume claims on agent sites are usually accurate but often describe the team rather than the individual.
Putting them together
The picture you want is: strong review counts on at least two platforms, recent dates, a Google profile with no unanswered complaints, and a sales record on Zillow that matches the price range the agent advertises. When those four agree, you can trust the recommendation. When they don't, the disagreement is the thing worth asking about in your first conversation.
