eBay offsite ads: how they work, what they cost and whether to opt in

What are eBay offsite ads?

eBay offsite ads are adverts for your listings that eBay places on websites and platforms outside eBay, so shoppers can reach your item from somewhere other than eBay search. You do not build the ads or choose the sites. eBay creates them from your existing listing details, mainly the title, photos and price.

The pricing logic is pay on results. You are charged only when a buyer clicks one of these ads and then buys the item. If nobody clicks, or somebody clicks and does not buy, there is no ad fee for that click.

That sounds like free exposure, and it is not. The fee is taken from the sale, so every ad sale is a sale on a thinner margin. The real question is whether the ad brings buyers you would not otherwise have had.

The details differ between eBay.co.uk and eBay.com, and eBay changes them from time to time. This article explains the mechanics and the decision. For the current rates, eligibility and settings on your own account, check eBay's pages and your Seller Hub.

How do eBay offsite ads work?

A shopper searches or browses on an external site and sees an ad for your item. They click it, land on your eBay listing and, if they buy, you pay the ad fee. Here is the sequence in plain steps:

1. Eligibility. eBay decides which listings and which sellers can be advertised. Not every listing will be used.
2. Ad creation. eBay builds the ad from your listing content. Your title, photos, item specifics and price are what shoppers see, so listing quality matters.
3. Click. A shopper clicks the ad and arrives at your listing.
4. Sale. If that shopper buys within eBay's attribution window, the sale counts as coming from the ad.
5. Fee. eBay charges the ad fee on that sale. It appears as a selling cost on your account.

An attribution window is the period after a click during which a purchase is credited to the ad. eBay sets the length, and it is stated on its advertising pages. For Promoted Listings general campaigns, eBay says the window is 30 days from the click. Check the offsite ads page for the figure that applies to offsite ads.

Where do the ads appear?

eBay decides this, not you. You cannot normally pick a particular site or ad slot for an individual listing. Because you control the listing but not the placement, the most useful thing you can do is make the listing itself strong: clear photos, a title buyers actually search for and accurate item specifics.

What do eBay offsite ads cost?

You pay a percentage of the sale when an ad click leads to a purchase. The exact rate depends on your marketplace and account, and eBay publishes and updates it. On some accounts eBay sets the rate. On others you may have a choice within a range. Look in Seller Hub for what applies to you, and read eBay's current offsite ads page for any cap per item.

For comparison, eBay states the rules for its general Promoted Listings campaigns: you pay only when the promoted item sells within 30 days of a click, and the fee is the ad rate as a percentage of the item's total sale amount, including item price, postage and taxes, at the rate in effect at the time of sale. You can read that on eBay's Promoted Listings page. Offsite ads are a separate product, so confirm on eBay's own offsite ads page how the fee base and rate work for them before you rely on the same assumptions.

Two points to keep in mind when you read the fee:

• The ad fee is charged on top of your normal selling fees, not instead of them.
• Fee bases can include postage and taxes, so the ad fee can be bigger than the same percentage of the item price alone.

How much of my margin do eBay offsite ads take? A worked example

Example: this uses hypothetical numbers and a hypothetical rate for the arithmetic only. It is not eBay's actual rate. Check eBay's fee pages for real figures.

Suppose an item sells for £30.00 in total, including postage. You pay £17.00 to source it. Assume a hypothetical eBay selling fee of 12% of the total, which is £3.60, and a hypothetical ad rate of 10%, which is £3.00.

An ad sale earns £3.00 less than the same sale without the ad. Whether that is acceptable depends on one thing: would this sale have happened without the ad?

Incremental sales decide the result

Continue the example. Suppose in a month 10 sales are credited to ads.

• If only 2 of the 10 would have happened anyway, then 8 are new sales. Without ads you would have made 2 sales at £9.40, which is £18.80. With ads you make 10 sales at £6.40, which is £64.00. You are ahead by £45.20.
• If 8 of the 10 would have happened anyway, then without ads you would have made 8 sales at £9.40, which is £75.20. With ads you make £64.00. You are behind by £11.20.

The numbers are invented, but the shape is real. Ads pay off when they bring new buyers, and cost you when they take credit for buyers who were already on their way.

Should you opt in to eBay offsite ads?

Opt in when your margin can absorb the fee and you want reach beyond eBay search. Opt out, or keep the programme limited, when your margin is thin or when most of your sales already come from repeat or direct buyers. Use this table as a starting point:

Do not decide on instinct. Run it as a test: set a start date, note your sales and profit before, and compare after a full period that covers your normal buying cycle.

How do you opt in or out of eBay offsite ads?

In most accounts you manage this in Seller Hub, in the Marketing or Advertising area. Menu names change, so look for an entry named Offsite Ads or Promoted Offsite. There you can see whether you are opted in, which rate applies and the status of your listings.

Whether you start opted in depends on your marketplace and account. Do not assume. Open the settings and check today, because ads you did not know about still cost margin.

Once you know your status:

1. Find the setting and write down what it currently says.
2. Find the rate or rate range that applies to you.
3. Check whether eBay allows opting out at account level, and whether there is any notice period or time before a change takes effect.
4. Record the date you change anything, so you can compare results later.

How are offsite ads different from Promoted Listings?

Promoted Listings place your item higher inside eBay, in search results and on item pages. Offsite ads place your item outside eBay. Both are paid for through results, but they reach shoppers in different places.

Because the placement differs, the sales you get can differ too. A buyer already on eBay and searching for your product may be reached by Promoted Listings. A shopper who starts on another site may be reached by an offsite ad. For how general and priority campaigns charge, read our guide to eBay Promoted Listings general vs priority campaigns. To set a sensible rate ceiling for on-site promotion, see how to choose a Promoted Listings ad rate.

Do not stack ad products without checking the rules. eBay explains how overlapping ads are handled on its advertising pages, so read them before you promote the same listing in more than one way.

How do ad fees fit with sourcing from Amazon?

If you source from Amazon, ad fees land on top of a cost that can move. Amazon prices change, and your margin changes with them. A sale that left £6.40 at one price can leave far less at another.

First, the rule. eBay's drop shipping policy allows dropshipping from a wholesale supplier. Listing an item on eBay and then buying it from another retailer or marketplace that ships directly to your customer is not allowed. Whatever your sourcing, you are responsible for the safe delivery of the item within the time stated in the listing and for the buyer's overall satisfaction. Read the policy for eBay.co.uk or eBay.com before you decide how to supply your listings. Paid traffic does not change this.

More ad-driven sales also means more orders to deliver on time. Late delivery and defects count against your seller record, and eBay may restrict selling or raise fees for sellers who fall below standard. Check the current thresholds on eBay's seller performance pages before you push for volume.

If you use Dropizon to reprice from Amazon readings, set your minimum profit floor with the ad fee in mind, so that a sale from an ad click still leaves the profit you need. The formula is yours to set. See how Dropizon works for the pricing and guard details.

What to do next

Work through this checklist before your next decision on offsite ads:

• Open Seller Hub and write down whether you are opted in and which rate applies to you.
• Calculate profit per sale with the ad fee included, using your real costs and eBay's current fee pages.
• Identify your products with the thinnest margin and decide whether they can carry any ad fee at all.
• Fix listing basics first. Photos must be at least 500 pixels on the longest side, and titles can be at most 80 characters. Ads built on a weak listing waste clicks. Our guide to eBay listing conversion rate shows what to change when views do not turn into sales.
• Run a dated test and compare sales and profit before and after, not just the number of ad sales.
• Check that your delivery promises hold up if sales rise.

Fee rules, eligibility and settings change, so confirm the details on eBay's own pages and in your account rather than relying on any third-party summary, including this one.
