Fix in this order

Ranked by how much each one costs the score, not by where it sits on the page.

  1. Rank trendFail-9 pts

    BSR #471 against a 90-day average of #366.

    Rank is a sales proxy, so a rank drifting away from its own 90-day average means units are going somewhere else. Establish whether it is price, stock, a competitor launch or advertising before it compounds.

  2. Product descriptionFail-6 pts

    No product description found.

    The description field is indexed and still shows on mobile even when A+ is present. Leaving it empty gives up both.

  3. Title lengthWarning-4 pts

    180 characters against the 75-character Item name field.

    Amazon generates its own split for titles over 75 characters and applies it after 14 days if nobody objects. Write the Item name and Item highlights yourself.

  4. Review velocityWarning-3 pts

    584 new ratings in 90 days against 810 in the 90 before.

    Reviews arriving more slowly than they used to is the earliest signal that sales are slowing, and it shows up before the rank does.

  5. Bullet pointsWarning-3 pts

    4 of the 5 bullet points Amazon allows.

    Unused bullets are indexed space given away. Fill all five, one benefit each.

  6. Offers on the listingWarning-2 pts

    2 active offers on this ASIN.

    Every extra seller on your ASIN is a share of your own Buy Box and a floor under your price. Brand Registry and a Transparency or Project Zero enrolment are what remove them.

Amazon reports 8,000 bought in the past month. At the current price that is roughly $79,920 of monthly sales on this ASIN alone, which is the figure the points above are costing a share of.

What passed (7)
  • Pass Images: 27 images on the listing.
  • Pass Video: 11 videos on the listing.
  • Pass A+ content: A+ content is published.
  • Pass Rank for its own keywords: Best position #2 for its own item type keywords.
  • Pass Star rating: 4.4 out of 5.
  • Pass Review volume: 29,283 ratings.
  • Pass Buy Box: A Buy Box offer is active.
Not scored (1)
  • Backend search terms: Amazon does not publish backend search terms for a listing you do not own, so this could not be scored.

Audit coverage

What the score is built from

  1. 01Content: title against the 75-character Item name field, bullets, images, video and A+.
  2. 02Discoverability: description, published search terms, and where the ASIN ranks for its own category keywords.
  3. 03Reputation: rating, review volume, and whether reviews are arriving faster or slower than they were.
  4. 04Commercial: Buy Box, competing offers, and rank against its own 90-day average.
  5. 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.

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.

Public inputs only

No account access required

The tools work with ASINs, Amazon URLs, keywords, and calculation inputs. Never paste passwords, tokens, or private account exports.

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?

Revenue Calculator, Rating Calculator, Merge Rating, and Title Analyzer currently use Amazon US. Listing Audit, ASIN Inspector, Keyword Analyzer, and Keyword Tracker support the United States, Canada, and Mexico.

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.
