Why Do Ratings for the Same Hotel or Restaurant Differ Across Platforms?
The same property almost always scores differently on Google, TripAdvisor, Booking.com and Yelp — not because one platform has bad data, but because each draws reviews from a different pool of guests, uses a different rating scale, and weighs recency differently. Below is a live, continuously-updated leaderboard of the real properties in ReviewsMerger's database with the biggest gaps between their highest- and lowest-scoring platform.
The Biggest Rating Gaps We're Tracking Right Now
Ranked by normalized point gap (0-100 scale) between a property's highest- and lowest-rated platform. Only properties with at least 20 reviews on two or more platforms are included, so a single outlier review can't create a misleading gap.

| C Living 3 - Al Malqa | Riyadh | 69/100 | Google 4.9 | TripAdvisor 1.0 | 78 |

Why the Same Property Scores Differently on Each Platform
The short version: Google collects reviews from anyone with a Google account who's visited, TripAdvisor skews toward trip-planners writing longer reviews, Booking.com only allows guests who booked and stayed through the platform, and Yelp's reviewer base is smaller and more North-America-centric in the GCC market. Different pools, different math, different number. For the full structural breakdown of what each platform measures, see how Google, TripAdvisor and Booking.com actually compare.
How Big a Gap Is Normal — and When It's a Red Flag
A gap of a few points is completely normal — it just reflects a different mix of reviewers. Gaps like the ones in the leaderboard above are worth a closer look because they mean the platforms genuinely disagree, not just about a few points, about the guest experience itself. Before assuming something is wrong, check the review count on each platform: a wide gap next to a lopsided review count (e.g. 500 reviews on one platform vs. 20 on another) usually points to a newer platform listing still catching up, not manipulation. A wide gap where both platforms have deep, comparable review counts is a genuine signal that the property performs very differently for different types of guests — which is exactly what ReviewsMerger's Trust Rating is designed to average out.

FAQ
Why do ratings for the same hotel or restaurant differ across platforms?
Right now the widest gap we track is C Living 3 - Al Malqa in Riyadh, rated 4.9 on Google but only 1.0 on TripAdvisor — a 78-point gap once both are normalized to the same 0-100 scale. See the leaderboard above for more real examples, updated live from ReviewsMerger's database.
How big a rating gap is normal, and when should it worry me?
A few points is routine — see the "How Big a Gap Is Normal" section above for how to read a larger gap in context of each platform's review count.
Does a big rating gap mean a property is faking reviews?
Not usually. Most large gaps come from a genuine difference in reviewer composition between platforms, not manipulation — see "How Big a Gap Is Normal" above for the review-count check that helps tell the difference.
How is the rating gap on this page calculated?
Every platform's rating is converted to the same 0-100 scale ReviewsMerger uses for its Trust Rating (Google, TripAdvisor and Yelp are out of 5; Booking.com is out of 10), then we take the difference between a property's highest- and lowest-scoring platform. Only platforms with at least 20 reviews count, so a single early review can't distort the ranking.
How often does this leaderboard update?
It's queried live from ReviewsMerger's database on every page load — not a fixed snapshot — so it reflects current ratings and review counts as they change.
Can I check the rating gap for a specific property?
Yes — ReviewsMerger's Compare tool shows any hotel or restaurant's live Google, TripAdvisor, Booking.com and Yelp scores side by side, and every property page shows its own cross-platform breakdown.
