What actually determines a REVIEWS.io rating
REVIEWS.io's own Fake Review Policy states that a widget displaying an average star rating "will use an average of all approved reviews, not a subset" — a plain arithmetic mean, not a weighted or Bayesian score like some competing platforms use. There's no documented recency decay or phantom-review dilution: every approved review counts equally, for as long as it stays approved.
A review counts toward a business's rating and review total from the moment it's submitted. The one timing wrinkle: 4- and 5-star reviews publish immediately, while 1-, 2-, and 3-star reviews can take up to 14 days to appear publicly as REVIEWS.io runs its automated fraud-detection checks. That's a publication delay, not a scoring adjustment — but it does mean a fresh negative review may not be visible yet even though it already exists in the system.
- Simple average — the published rating is an arithmetic mean of all approved reviews, with no weighting or decay applied.
- Mandatory full-invite — REVIEWS.io requires businesses to invite every customer who transacted, not a hand-picked subset, so the rating reflects the whole customer base rather than a curated slice.
- Publishing delay on lower ratings — 1–3 star reviews can take up to 14 days to go live while fraud checks run; 4–5 star reviews publish immediately.
- Verified Buyer status — reviews left in response to a post-purchase invite carry a "Verified Buyer" badge once proof of purchase is confirmed, which shoppers weight more heavily than unverified content.
- Moderation, not deletion — a genuine, verified, factually-correct review is never removed for being negative; only reviews that breach the published Fake Review Policy are eligible for removal, and only REVIEWS.io's moderation team can approve that.
