Same ad rate, same listings, bigger advertising line on your monthly fees. If that's what you've noticed since the start of the year, you're not imagining it, and it's not something you did. eBay changed how it decides which sales an ad "caused" — and the new definition catches a lot more of your ordinary sales than the old one did.
What actually changed
On January 13, 2026, eBay rolled out a new attribution model for Promoted Listings Standard general ad campaigns on ebay.com, ebay.ca, and cafr.ebay.ca (the change had already landed in other countries earlier). It replaced the narrower model that had been in place for years, and eBay's own seller announcement spells out the new rule plainly: a sale is now attributed to your ad, and charged the ad fee, if any buyer purchases the promoted item within 30 days of any click on that ad — not just the buyer who actually clicked it.
The item just has to be actively promoted at the moment of the click and still promoted at the moment of the sale. Who clicked, and whether the buyer who eventually paid ever saw the ad at all, no longer matters.
Why that's a much bigger net than it sounds
Under the old model, an ad fee generally required a real line from click to purchase — someone clicked your promoted listing and that same shopping session or that same buyer went on to buy it. Plenty of your sales never touched a promoted click at all: a buyer searching directly for your title, a repeat buyer who bookmarked your store, a sale on a multi-quantity listing where only the first unit ever got clicked from an ad slot.
The new rule pulls all of those into the ad fee. If any click landed on that listing in the last 30 days — from anyone, for any reason — the next sale of that item is attributed, whether or not the buyer who paid ever saw the promotion. eBay's own community forum and reseller trade press have tracked the same pattern in the markets that got this change first: attribution rates that used to run around 50% of sales climbed to 80–90% or higher in most categories once the new window took effect. Nothing about your ad rate setting changed. The share of your sales it now applies to did.
A worked example
Say you run a Promoted Listings Standard campaign at a 6% ad rate on a listing you have three units of, each selling for $40.
- Day 1: a shopper clicks your promoted listing, browses, and doesn't
- buy.
- Day 4: a different buyer finds the same listing through a plain
- search, no click on the ad, and buys one unit.
- Day 19: a third buyer, also arriving without clicking the ad,
- buys another unit.
Under the attribution rule that applied before January 13, 2026, neither of those two sales would likely have been charged an ad fee — no buyer clicked the ad and then bought. Under the current rule, both are attributed, because a click landed on that listing within the prior 30 days and the item was still being promoted at the time of each sale. That's 6% × $40 = $2.40 in ad fees on each of two sales — $4.80 — that the old model wouldn't have charged, on top of whatever the ad legitimately did generate. Run that across a store with dozens of active promoted listings and steady repeat or organic traffic, and the advertising line on your monthly invoice grows without you touching a single setting.
What to actually do about it
- Check your attributed-sales percentage in Seller Hub's ad reports,
- comparing a recent period to one from before mid-January 2026. If it
- jumped sharply while your actual click-through traffic looks about the
- same, this is why.
- Re-run your ad rate math with the new attribution rate in mind. A 6%
- rate that penciled out when it applied to roughly half your sales costs
- meaningfully more once it's applying to 80%+ of them. Lowering the rate
- is the lever you have — the attribution rule itself isn't something you
- can opt out of on a General campaign.
- Watch multi-quantity and duplicate listings closest. A single click
- on a listing with several identical units on sale can now generate an ad
- fee on every one of those units sold in the following 30 days, not just
- the one the click led to.
- Don't assume your ad rate is still doing the same job it was in 2025.
- The rate hasn't moved. What it's charged against has.
eBay has said its ad rate and attribution terms can change without advance notice to sellers under its current marketing terms, so treat this as a number worth rechecking periodically rather than a one-time fix.
PalmFlow logs Promoted Listings spend against the sale it's attached to, the same as final value fees and shipping, so when eBay's attribution rules change what counts as an ad-driven sale, it shows up in your real per-item margin instead of getting buried in one lump advertising total for the month.
