Why this is a snapshot, not a trend
This is a snapshot of one shared review period. The source has no earlier matching period, so this article does not measure change over time.
What operators can compare with their own reviews
The measured sample gaps are service (Tripadvisor higher by 23.34 percentage points), food consistency (Tripadvisor higher by 17.47 percentage points), and wait time (Tripadvisor higher by 10.77 percentage points).
The remaining measured sample gaps are location (Tripadvisor higher by 9.29 percentage points) and atmosphere (Tripadvisor higher by 7.05 percentage points).
Then calculate the same topic shares for the same period on each platform. Check praise and complaints separately for service, food consistency, wait time, location, and atmosphere, and treat these unmatched sample gaps as questions rather than performance targets.
In this source, atmosphere, food consistency, and service appear in both praise and complaint evidence. Compare both sides before interpreting the sample gaps.
Use cleanliness complaint (0.07 percentage points) and atmosphere complaint (0.39 percentage points) as close-sample references when checking whether platform mix is shaping the comparison.
Limitations
The platform samples use different review and business denominators and do not match businesses one by one. Differences describe the samples, not platform effects.
The topic analysis is smaller than the broader summary, so its percentages do not describe every review in the full coverage.
Methodology and source notes
Topic shares use distinct reviews from the shared review period. Each review has equal weight.
