Most eBay sellers open Seller Hub to check orders & process shipments. The ones consistently growing their stores are doing something different they're treating Seller Hub as a data engine & using it to make every listing, pricing & advertising decision.
In 2026, Seller Hub is more capable than most sellers realise. Here's how to use it properly.
The Research Tab: Your Competitors' Sales Data, Free
Terapeak is eBay's built-in product research tool, available free to all Seller Hub users. It shows historical sold prices, sell-through rates & competitor listing data for any search term.
That means you can see exactly what price your category sold at over the last 12 months, which item specifics appeared in the top-converting listings & what percentage of listings actually sold the sell-through rate versus sitting live with no buyers.
Sourcing Insights, available to Store subscribers, extends Terapeak to category-level analysis: which product categories are growing on eBay, what item-specific combinations are most in demand & where there are inventory gaps categories with high buyer demand but low seller supply.
For any seller looking to expand their catalogue or source new product lines, this becomes a direct competitive roadmap.
Most sellers type in a product, glance at the average price & close the tab. The sellers winning their categories are reading the full data set — sell-through rates, condition breakdowns, Promoted Listings penetration & adjusting every listing decision accordingly.
With Rootamz, sellers can combine marketplace research, listing optimization, advertising strategy & data-driven growth solutions to scale smarter. As an Amazon Ads Verified Partner, Rootamz helps brands maximize their Amazon advertising performance through advanced campaign strategies, optimization & marketplace expertise.
The Growth Tab: Your Listing Quality Score & Why It Matters
The Growth tab assigns every listing a quality score based on completeness, item specifics, image quality & description depth. Listings with poor quality scores receive specific recommendations add these item specifics, improve this title, add more images that you can act on directly.
This isn't cosmetic. Improving listing quality scores is directly correlated with improved search ranking in eBay's Cassini algorithm, which prioritises listing completeness & relevance as core ranking factors.
The compounding benefit is in Promoted Listings. eBay uses quality scores combining ad rate, listing quality & seller metrics a strong seller with better listing quality can outperform sellers spending more on ads.
Fixing your Growth tab recommendations doesn't just improve organic rank it directly reduces what you need to spend on advertising to maintain visibility.
Work through the Growth tab systematically: item specifics first, then image count, then returns policy. These three fixes alone move most listings from a medium to a high quality score.
The Performance Tab: Find Where Your Traffic Is Actually Dying
The Performance tab gives you a quick overview of key indicators: sales trends, selling costs, traffic & your seller level Top Rated, Above Standard, or Below Standard.
Beyond the summary, the Listing Quality Report downloadable from Performance is where you find the category-level detail. It provides analysis of your top categories, showing what other sellers include in their listings & what's working in each category.
Pull this report monthly. Filter by listings with high impressions but low click-through rates these are listings that eBay is surfacing but buyers are rejecting at first glance.
That signals a title, pricing, or lead-image problem that data can diagnose.

What is the Growth tab in eBay Seller Hub?

How does eBay's Cassini algorithm use listing quality scores?
Cassini prioritises listing completeness & relevance. A higher quality score driven by complete item specifics, strong images, competitive pricing & an accepted returns policy improves organic search position. Quality score also feeds into Promoted Listings rank, meaning better-optimised listings need lower ad rates to achieve the same visibility.
