Overview

Product research and eBay SEO from a single keyword.

What it does

RankHero's eBay Product Research turns a single keyword into a full market readout plus an eBay SEO checklist: pricing, competition, best-fit category, the item specifics Cassini expects, and the title language top listings repeat. Stop guessing what to list at and how to title it.

Why eBay SEO matters

eBay's Cassini search engine, the heart of eBay SEO, ranks listings on title relevance, price competitiveness, item specifics, and conversion. Listing in the wrong category, mispricing against the median, or missing required specifics quietly buries your listing in search, even when the product is great.

Getting started

How to use it.

  1. 01

    Enter a product keyword

    Type the product term a buyer would actually search, e.g. "vintage levis 501" or "pokemon card binder". Specific beats vague.

  2. 02

    Read the market snapshot

    Use the median price as your anchor and the price range to bracket competitive listings. The trend chart shows whether demand is rising or seasonal.

  3. 03

    Match the category and specifics

    List in the suggested category and fill every Required item specific. Recommended specifics are optional but lift visibility in search.

  4. 04

    Borrow the title keywords

    Weave the high-frequency title terms into your listing title. These are the eBay SEO keywords Cassini already rewards. Sample listings show how competitors arrange them at the price you're targeting.

FAQ

Frequently asked questions.

eBay SEO is the practice of optimizing a listing so it ranks higher in eBay's Cassini search engine. The main levers are listing in the correct category, filling required and recommended item specifics, writing a title with the keywords buyers actually search, and pricing competitively against the market median. This tool surfaces every one of those signals from a single keyword.

It gives you the four inputs Cassini cares about most: the best-fit category and category ID, the full list of required and recommended item specifics for that category, the title keywords top-ranking listings actually use, and the price range the market is converting in. Apply them to a listing and you've covered the core of eBay SEO.

Live eBay Browse and Taxonomy APIs. Listings, prices, shipping, the suggested category and item specifics are all pulled in real time from the marketplace, with no cached or scraped data.

We split the active listing prices into three zones so you can see where the market clusters at a glance. Bargain is the lowest third of prices, Midrange is the middle, and Premium is the top third. The dots show every individual listing. Gaps and clusters tell you where pricing competition is thickest and where there's room to land.

Required specifics must be filled. eBay won't let you publish without them, and they directly affect search filter eligibility. Recommended specifics aren't mandatory but lift visibility in Cassini search and let your listing match more buyer filters, which is one of the strongest eBay SEO signals. Fill as many as you can.

We pass your keyword to the Google Ads Keyword Planner API and pull back up to 50 closely related searches, scoped to the country of the marketplace you selected. Your seed keyword is filtered out, and each suggestion comes back with its real Google average monthly search volume, so you can spot adjacent terms with demand and weave the strong ones into your title, description, and item specifics for stronger eBay SEO coverage.

Usually yes. eBay's category suggestion is based on what live listings for that keyword sit in, and category fit affects search filters and item specifics. Override only if your product is genuinely a niche variant that belongs elsewhere.
