How to Check a Seller's Review Score in 60 Seconds

A star rating on a seller’s own homepage is the easiest trust signal to display and one of the easiest to check — and almost nobody checks it. It takes about sixty seconds. Here is the method, and a worked example from our own register where the badge said 4.8 out of 5 and the platform it named had never heard of the company.

The check

1. Go to the review platform directly rather than clicking the badge. For Trustpilot the address is predictable: trustpilot.com/review/ followed by the seller’s domain. If that page does not exist, the profile does not exist.
2. Search the platform for the company name too, in case the profile sits under a different domain. A real business with hundreds of reviews is not hard to find.
3. Check the Better Business Bureau for the legal entity name, which is often different from the brand.
4. Look for a Google Business Profile. A claim of “300+ Google reviews” means there is a profile somewhere holding them.
5. Compare the seller’s own numbers with each other. Marketing counters are written by different people at different times and often disagree.

What that turned up for one seller

When we ran this against LVNG RX on July 26, 2026, the homepage displayed a Trustpilot badge reading “Rated Excellent, 4.8 / 5”. The Trustpilot page for its domain returned the message that the page could not be found, and a Trustpilot company search returned 138 results with no LVNG RX among them — the closest match being an unrelated shop in the Netherlands.

A second block on the same page claimed 4.9 based on more than 300 Google reviews, listing six named reviewers marked “Verified”. No Google Business Profile or review count surfaced for the brand. And two of those reviewer names were reused as the names attached to the before-and-after transformation photographs elsewhere on the site.

The same two first names appeared as verified reviewers and as the people in the transformation photographs.

Its self-reported counters also disagreed with each other: a hero line reading “10k+ trusted by thousands of members” sat on the same page as a counter reading “1,743+ patients supported”. Both cannot be describing the same business.

The distinction that matters more than the example

It would be easy to read the above and start treating every seller without visible reviews as suspect. That would be wrong, and it is worth being precise about why. There are two completely different situations here.

The check also works in the other direction, which is the part that makes it a method rather than a way of finding fault. Sprout Health, run through the identical process on July 14, 2026, turned out to have exactly what it implied: a real Trustpilot profile, 3.5 stars across 113 reviews, claimed in March 2026. A middling score that genuinely exists is worth more than an excellent one that does not.

Before-and-after photographs

These deserve their own note because they are the least verifiable thing on any of these websites. There is no registry of transformation photographs and no way to confirm one from the outside. What you can look for is internal consistency: names that also appear elsewhere on the site, images that recur across unrelated brands, and results presented without any indication of how typical they are.

Six sellers in our register carry a note about stock or reused imagery. That is not a large number out of 560, and the reason it matters is not the count — it is that a photograph is the most persuasive thing on a sales page and the least checkable. Weight it accordingly, which is to say barely at all.
