What actually shapes a Houzz profile
The star rating shown on a Houzz professional profile is a straightforward average of the 1–5 star scores that verified clients leave — Houzz hasn’t published a Bayesian or recency-weighted formula the way some review platforms have. Every review goes through a moderation check for spam and fraud before it posts, which Houzz says can take "up to 5-7 business days, depending on our current volume."
But the star average isn’t the only thing that determines whether a homeowner sees a pro in the first place. Houzz’s own guidance on how its Pro directory works points to several ranking inputs beyond reviews: the number and quality of photos on a profile, how often the community engages with those photos and answered Q&A, whether the pro displays the Houzz badge on their own website, how complete project entries are (cost and location), and how quickly a pro responds to messages from prospective clients. Reviews are one input among several, not the whole algorithm.
- Star rating — a simple average of the 1–5 star scores verified past clients submit; each client can review a given professional once.
- Review moderation — every submission is checked for spam and authenticity before it posts, a process Houzz says can take up to 5–7 business days.
- Directory ranking — a separate set of inputs beyond the star average, including photo count and quality, community engagement, Houzz badge usage, project-info completeness, and responsiveness to messages.
- Policy compliance — reviews that violate eligibility rules (wrong client/project, prohibited content, undisclosed conflicts of interest) are the documented basis for removal, not simply being negative.
