How to Fill eBay Item Specifics (and Why They Matter)

Item specifics are the labelled details buyers filter by. Here's how Prelo fills them from evidence only, and how to fill the rest yourself.

Item specifics are the labelled details on an eBay listing: brand, type, colour, material, size. Buyers use them to filter search results, so a blank one can keep your item out of a filtered search. This tutorial shows how Prelo handles them. The item in the video uses example data.

The Item specifics card

Open a drafted item in Prelo and scroll to Item specifics. It shows how many of eBay's recommended specifics for that category are filled. Which specifics count depends on the category: eBay keeps a list for each one, so if the category is wrong, fix it first.

Filled only from evidence

Prelo fills a specific only when there's evidence for it:

  • something you typed,
  • something your title or description says,
  • or a reading from your photos that matches one of eBay's allowed values.

Everything else is listed under Missing — only you can confirm these. Some rows have a suggestion, with where it came from: your description, your title or the photos. Check it before you tap it. Choose or type a value and press Save. Filled specifics move under Show filled.

Required specifics

If eBay requires a specific and it's still blank, the card tells you. At publish, Prelo fills a best guess or "Does Not Apply". Size is never guessed.

In the editor

You can also edit specifics in the editor, under Item Specifics. Press Add for a new row, type the name, then the value. For more than one value, separate them with commas. The bin icon removes a row. They're sent to eBay with the listing.

New, branded items

For new items with a brand or barcode, a price check can also match the item to eBay's catalog and fill the blanks from there. Tutorial 10 covers that.
