How to run a Parts Compatibility Finder report video

The Car Parts Compatibility Finder tool works as follows:

  • Scan your eBay store listings.

  • Extract vehicle information and parts-related information (if present) including Title, Brand, Parts Numbers (such as EAN, MPN) from your listings.

  • This information is then processed and used to lookup our data-sources for a match.

  • If a match is found, then we will return you a File-Exchange ready file with the relevant revise information for your listing which will include KTypes and Fitting position data.

For the tool to be effective, you should either have vehicle information in your listing Titles, or Product identifiers such as UPC, EAN or Brand & MPN in your item specifics.
As a note; the tool does not look at your description as that may contain other non-relevant information that may affect the reliability of the tool.

For vehicle information, the tool requires at least the minimum of Make, Model and Year or Year range to match on, but the more data you have within your listing, the more accurate the matches provided will be.

Below shows a few examples, as you go further down the list the matches are a lot better:

"Ford Mondeo Hatchback" - this would not match as it does not have any year info
"Ford Mondeo 2004" - this would match on Ford Mondeo models that started to be manufactured from 2004
"Ford Mondeo 2004-2007" - this would match on Ford Mondeo models available from 04-07
"Ford Mondeo 2004-2007 Hatchback" - this would match on Ford Mondeo models available from 04-07 with the bodystyle hatchback
"Ford Mondeo 2004-2007 Hatchback 2.2 TDCi" - this would match on Ford Mondeo models available from 04-07 with the bodystyle hatchback and 2.2 TDCi engine

As a note; Years can also be provided using 2 digits e.g. 02-04 02 04 etc.

The results can be filtered and exported by brand, category, sales performance.

The data can also be filtered for Listings that do not already have existing fitment, listings with increased fitment, catalog matches (relevant in certain regions only), and listings matched based on other listing data:

If an eBay ePID cannot be located, the tool will then attempt to source the fitment data using other marketplace data with stringent checks in place to verify that the data is valid for the product.

How to use the tool (for AU)

New users should sign up here - Optiseller sign up. You will receive an email confirming your details and instructions on how to login to the tool.

Please note: if you are on the white-listed eBay program, your store will automatically get processed and you can skip to step 3 below

  1. Once logged in you should subscribe to the "Parts & Accessories" Essential or Ultimate Plans:

2. Once signup is completed, you will see the store being processed on the home page, and when completed you will be able to access your report and download the results.

To run a Parts Compatibility Finder report for AU:

Select Region > AUS

Select Vehicle > Cars (or Motorcycles if you sell motorcycles)

Then you have an choice of 3 Reports to run:

1. Download All Listings - this downloads all your eBay listings up to a maximum of 150,000 listings.

2. Download Selected Listing - you upload a list of eBay item ID's via .CSV or .TXT format.

3. Download by Category - you can choose the categories you wish the download for.

Tip - For larger sellers due to the limits, Option 3 is the best option as it will allow you to focus on category by category, for example run a report Brake Pads, then run a report Brake Discs etc.

The report page allows you to view the results, filter and export data:

The key aspects of the results page are:


The guidance section provides a summary of the items scanned, how many matches and also suggestions for improvement. In this case we can see that there are 7484 listings that have partial vehicle data which suggests there are vehicles in the titles but not detailed enough or perhaps missing year information.

The log-file can be downloaded to view the exact details of matches and failures to match. The log-file can be quite interesting as it points out various missing items from your part data.

  • Total Products Processed: Total number of listings processed. If the tool is run multiple times, only listings that have changed in a way that would affect the chances of matching will be re-processed. For example the tool will not look at the same listing twice unless the title and part information have changed.

  • MVL: the different levels of match confidence using vehicle information to cross reference the eBay Master Vehicle List (MVL)

  • EasyProduct match: Items where we found at least 3 other listings with consistent fitment records.

The filters allow you to export via brand, category, listings with at least X sales, items that do not have any fitment, items which will increase the fitment, items matched with epids only, and items matched via other listings only.

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