Audit coverage
What the score is built from
- 01Content: title against the 75-character Item name field, bullets, images, video and A+.
- 02Discoverability: description, published search terms, and where the ASIN ranks for its own category keywords.
- 03Reputation: rating, review volume, and whether reviews are arriving faster or slower than they were.
- 04Commercial: Buy Box, competing offers, and rank against its own 90-day average.
- 05Every check that public data cannot answer is left out of the score instead of counted as a failure.
Reading the score
- 85–100 Strong. Nothing on the page is holding it back.
- 70–84 Solid. Real gaps, none of them urgent.
- 50–69 Needs work. Something here is costing sales.
- 0–49 At risk. Fix the listing before spending on traffic.
The score measures the listing against the checks above, not against the other listings in your category. A competitor can score lower and still outsell you.
Enter an ASIN and the audit scores the listing out of 100 across content, discoverability, reputation and commercial signals, then ranks what to fix by what each failure costs. It also checks the listing against itself, because a description that disagrees with an attribute is now an answer Amazon’s assistant gives a shopper.
Why an agency gives these away
These are the checks our specialists run on client accounts before they change anything. Opening them costs us little and answers a seller straight away, without an account connection, a trial, or a sales call first. Some of those answers turn out to be worth a conversation, and that is the whole trade.
Built for decisions
Results with context
A metric is useful only when you know what produced it. Results connect product, market, cost, listing, rating, and visibility signals instead of returning one unexplained score.

Free tools FAQ
Are the UNITIX Amazon seller tools free?
Yes. All seven are free: Listing Audit, Revenue Calculator, ASIN Inspector, Keyword Analyzer, Keyword Tracker, Rating Tools, and Title Analyzer. The rating tools include two modes.
Why does an agency publish free seller tools?
These are the checks UNITIX Agency specialists run on client accounts before they change anything, and they are cheap to open to everyone. A seller who runs one gets a straight answer at no cost. Some of them find a problem worth a conversation, and that is the whole trade.
Do I need to connect my Seller Central account?
No. The tools accept public ASINs, Amazon product URLs, keywords, and the cost inputs needed for a calculation. Do not enter Seller Central credentials.
Which Amazon marketplaces are supported?
Listing Audit, ASIN Inspector, Revenue Calculator, Rating Calculator, Merge Rating, and Title Analyzer cover the United States, Canada, Mexico, the United Kingdom, Germany, France, Italy, and Spain. Keyword Analyzer and Keyword Tracker cover the same eight. They read Amazon's search terms report, which we hold for all eight.
Where do I start if I do not know what is wrong?
Run the Listing Audit. It scores one ASIN out of 100 across content, discoverability, reputation, and commercial signals, and orders the fixes by what each one costs. The other tools answer a question you already know to ask; this one tells you which question to ask.
What can the Rating Tools calculate?
Rating Calculator estimates how many new 5-star ratings an ASIN needs to reach a target. Merge Rating combines multiple ASIN rating distributions using their rating volumes instead of a simple average.
The tool found a problem. What comes next?
Share the result with UNITIX and we will tell you whether the constraint is advertising, listing conversion, competition, or account structure.
