Listing Optimizer

Ad spend can only do so much for a listing that doesn't convert once a shopper lands on it. Listing Optimizer scores your catalog on the two things Amazon shoppers actually judge: how well your copy covers the keywords people search for, and how complete your listing data is against what Amazon asks for. That way, you know which listings are worth improving before you spend more on ads pointing at them.

Before you start​

  • At least one Amazon account connected
  • An active Selling Account connection: this feature needs listing and search data Amazon only shares with a connected Selling Account. Ads-only accounts see a banner instead of scores.

The listing table​

Every ASIN in your catalog gets a row with three scores:

  • Overall: the combined health score for the listing
  • SEO Coverage: how well your title, bullets, description, and backend keywords cover the terms shoppers actually search for that product
  • Attributes: how complete your listing's structured data is against what Amazon requires and recommends for the category

Alongside the scores, you'll see 30-day ad metrics (spend, sales, revenue) so you can prioritize by impact: a low-scoring listing with real ad spend behind it matters more than one that's not being advertised at all.

Filter by score band (Unscored, Needs work, Fair, or Good) to work through your catalog in priority order, or use the ad-metric filters to find spend concentrated on weak listings.

Scores load progressively: rows appear immediately with their image, title, and ad metrics, then scores backfill in the background as you scroll. A coverage line ("N of M listings scored") shows up whenever a score filter is active, since filters only search listings that have finished scoring.

How scores are calculated​

SEO Coverage starts from your product's top search terms: real Amazon search queries from Brand Analytics plus search terms that have actually converted through your ads. A term counts as covered when all of its words appear somewhere in your listing (title, bullets, description, or backend keywords), in any order. That mirrors how Amazon's search index works. Terms don't need to appear word-for-word: "Gift Set for Dungeon Masters" covers "dungeon master gift set" just fine. Placing a term's words in your title earns extra credit, since the title carries the most search weight. Each term is weighted by its search volume, so covering high-traffic terms moves the score more.

Attributes is based on Amazon's own category schema: attributes Amazon requires count for 80% of the score and attributes it recommends count for 20%. Purely optional attributes are shown in the grid but never counted against you: filling every field is not the goal, and the score doesn't pretend it is. The page shows the plain version too: "12 of 14 required filled."

Overall combines the two (60% SEO, 40% Attributes). When there isn't enough search data to measure SEO coverage (common for new or low-traffic products), Overall shows a dash with an explanation rather than a misleading substitute number.

Per-ASIN detail​

Click a row to open the detail view for that ASIN, with three tabs:

  • Keywords: a coverage table showing which search terms your listing covers, which words are missing, and where. Add your own target keywords, or dismiss terms that aren't relevant to your product. Both feed directly into the score. Dismissed terms sit in a collapsible list and can be restored anytime.
  • Attributes: Amazon's own compliance issues for the listing, plus an editable attribute grid so you can fill in missing fields without leaving SellerJar.
  • History: every change you've sent to Amazon through SellerJar, with the old and new values, when, and by whom. Any change can be reverted: the previous value loads back into the editor and goes through the same review and validation as a normal edit.

Editing your listing​

The preview panel lets you edit title, bullets, description, and backend keywords with live keyword-coverage highlighting as you type.

  • Character counters show Amazon's guidelines, not arbitrary limits. Bullets read "N / 255 recommended": 10-255 characters is Amazon's best-practice band, staying neutral throughout; going over turns advisory amber (the enforced cap varies by category) and only far past it turns red.
  • Compliance warnings check your draft as you type and come in two honest tiers: suppression risk for terms that can genuinely get a listing suppressed (medical claims, environmental claims, guarantees), and style suggestions for advisory wording that isn't a policy violation. Everyday words like "quality" are never treated as violations.
  • Empty fields that aren't really empty. Amazon stores listing content per marketplace: if your UK page shows bullets that were written on your US listing, the UK fields are genuinely blank on Amazon's side until you submit them there. The editor tells you when that's the case and offers one-click Copy from US (or whichever marketplace has the content) so you can submit it properly.

Vendor accounts can see scores and coverage, but edits must be pushed through Vendor Central. SellerJar doesn't support writing changes back for vendor listings.

Amazon's 2026 title changes​

Since July 27, 2026, Amazon caps product titles at 75 characters including spaces for every category except media (books, music, video, software), which stays at the older, longer limit. Listing Optimizer already enforces the new limit: the title field's live character counter and over-limit warnings are 75-char aware, and the AI title rewriter targets that budget by default, moving anything that doesn't fit into your bullet points instead of truncating it.

Titles still sitting over 75 characters are being gradually auto-rewritten by Amazon itself after that date. If Amazon rewrites one of your titles, you get 14 days to review the AI-generated change in Seller Central's Review Listing Changes before it's treated as final, so it's worth trimming titles proactively rather than waiting for Amazon's version.

Item Highlights is the separate 125-character field Amazon shows below the title in search results and on product pages, as long as the title fits the 75-character cap. SellerJar supports it end to end: the Preview panel shows an Item highlights box directly under the title, Optimize writes it together with the title so the two never repeat each other, your tracked keywords light up inside it, and Send pushes it to Amazon with the rest of your edits. The box only appears for product types where Amazon accepts the field (media categories and the SA, EG, TR and AE stores do not have it). Keywords placed in Item Highlights count toward your SEO score exactly like keywords placed in the title.
