Features & Benefits
What is the Parts Compatibility Finder and how will it help me?

The PCF tool will scan all of your live listings on eBay and provide suggestions for vehicle parts compatibility for both cars and motorcycles. The eBay Store Performance Dashboard will monitor your listings to ensure you have your compatibility up to date, as well as monitoring for part numbers, keywords, shipping options and more.

We make it simple to state which vehicles your parts are compatible with, and for buyers to find the right parts for their vehicles.

  • Easily match parts to compatible vehicles
  • Eliminate need for multiple listings
  • Boost in 'Best Match' and 'Organic' search
  • Competitor analysis
  • Visibility and Confidence

Interpret & Match
What makes a confident match and when to edit the data to get more matches using the system?

Your parts compatibility listings get a boost in 'Best Match' and 'Organic' search, and you can use your 80-character title for popular search elements like brand or part number to better market your listing. It also becomes available on eBay My Garage, increasing visibility.

Data shows an average of 27% increase in sellers conversion rate when using the Parts Compatibility Finder.

The data is provided in a seller hub report format , ready for upload to eBay directly, or with some manipulation, your listing tool of choice.

We also provide a detailed log file which highlights how we decided on the match, allowing you to review the matches in more detail, and identify where matches have failed and opportunities to add more data to assist.

We recommend using it whenever you have listed new products, and also at least twice a year in March and September for new vehicle registration plates.

A better way for sellers to list parts that fit a variety of vehicles

The parts compatibility finder will scan your live listings and attempt to source fitment/compatibility data for your listings. It does this by using any vehicle information you may already have in your titles (e.g. Audi A4 Avant 2009), and any part related information you have in your item speciifcs (e.g. Brand MPN, EAN, Part Numbers, etc)


Pro Tip: Having compatibility on your listings is the equivalent of item specifics for your eBay listings.

"Aspect Finder+ has been a very handy tool for us. The export function is easy to use and makes it possible to export the item specifics in file exchange format, edit in Excel in bulk and upload again via eBay file exchange. It works a treat!"


"Using Optiseller allowed us to quickly identify and update all required Item Specifics for all of our listings. The support from Optiseller was great. The tool was simple to use, and the ability to download a CSV file directly for uploading to file exchange made it very easy to update in bulk. This has had a positive increase in sales for us, as listings are now appearing higher in eBay's search engine. I am now keen to establish other tools offered by Optiseller that we can utilise to our advantage."


"We find the Optiseller tool very useful, and the team very responsive. Our external systems are the "master" data rather than eBay, but even so, we find that Optiseller is effective at guiding our efforts when it comes to Item Specifics. All in all, a great help!"


"Aspect Finder+ is a fantastic tool. The new items sold/quantity column is a fantastic addition, and we find the eBay category lookup tool particularly useful for populating our item specifics using Volo. In the first two months of using the tool we noticed that around 100 listings we optimised sold more in 8 weeks than in the 12 previous months."
