Selecdoo Growth Engine · Pay per sale
Extra sales.
You only pay when you sell.
Additional sales channels for your shop – on our budget, at our risk. You pay the normal commission on real sales. Nothing else.
First things first
The promise in three sentences
Additional reach via search, shopping and social – publishers cover the budget and the risk.
You only pay the normal commission on confirmed sales.
Your only step: grant shop access once. Selecdoo connects everything else for you.
The balance
What you gain. What you don't take on.
What you gain
- Revenue potential from channels you do not run yourself.
- The customer lands in YOUR shop.
- The customer data stays with you.
- No cash flow commitment.
What you don't take on
Upfront: €0
- No additional click budget
- No upfront cost
- No campaign management on your side
- No changes required to your existing Google Ads setup
- No channel you have to keep if it does not pay off
Process
How it works
Selecdoo only needs shop access via the Shopify Partner Portal and connects everything for you.
- Step 1
Grant shop access
Via the Shopify Partner Portal. Nothing else to prepare.
- Step 2
Done – your commission rate stays
Your existing commission rate applies – no additional one is needed. Everything stays as it is. Selecdoo handles the integration, the feed and the additional tracking pixel completely.
The CSS model
More coverage in the auction — without bidding against yourself
Via CSS your products are represented a second time in the shopping auction — through a separate, independent channel. The share that would otherwise go to competitors shrinks. Your own campaigns stay untouched.
Standard Google Shopping campaign
With the CSS partner
Your own coverage stays at 30%. The additional 15% comes from the CSS channel — at the expense of competitors, not of your campaigns.
A different channel
The model runs through a separate, independent channel — apart from your Google Ads account.
A parallel auction
There is no bidding against your own campaigns. You never bid against yourself.
Additional yield
Merchants using the model report incremental sales compared with their own campaigns alone.
Quick activation
Live within a few days. No upfront cost, no hidden fees.
The coverage figures are a model example explaining the mechanics — not a guaranteed result. How large the additional share is in your category depends on assortment, price position and competition. The CSS model itself is a market standard and is also used by large retailers and marketplaces such as eBay.
Potential example with a good assortment fit
What this can add up to
Model scenario based on Selecdoo benchmarks and industry figures – not a guaranteed result. Actual numbers depend on assortment, margin and branded search demand. With a weaker fit they will be lower.
Starting point: D2C shop, average net basket €75, own Google and Meta campaigns running. From around 30,000 visitors per month the system pays off – below that there is not enough data for AI targeting.

At 11% commission plus a 30% network fee your effective cost ratio stays constant at 14.3% of the net basket — regardless of volume. Revenue-to-cost ratio: 6.99x. Worst case: 0 sales = 0 cost.
Result from practice
Not a model — measured

Transparency — this is what runs
Additional reach channels are used on your behalf – among them search engine ads (including your brand name as a keyword), Google and Microsoft Shopping via CSS, and social retargeting. For this, an additional tracking pixel is placed in your shop. All advertising costs are borne by the respective partner. You pay commission on confirmed sales only. Post-view is never used — Selecdoo rules it out on the technical level.
In addition — not instead
"And what if you're already running Google Ads?"
Perfect. The Growth Engine doesn't replace your existing setup. It adds another performance-based sales channel.
Most stores here already run Google Ads or work with an agency. Those campaigns stay exactly as they are. The publishers use their own media budget — and you only pay when a confirmed sale comes out of it.
"Will I end up paying for sales I would have got anyway?"
Nobody can honestly claim that for every single sale — which is exactly why you should measure it. What matters is not how many sales the publishers book for themselves. What matters is whether your store generates more profitable revenue overall with the extra channels.
Don't take our word for it. Measure it.
Compare before and after launch: total revenue, orders, cost and — if available — new customers. If a channel adds no economic value, there is no reason to keep scaling it.
"Will this make my Google Ads agency look worse?"
No. Nobody takes over your existing Google Ads account. Your agency keeps running and optimising its campaigns exactly as before. The publishers work alongside them, with their own budget.
Two channels in the same market can influence each other. That is why the overall result is what counts afterwards: does your store make more money with all channels running together?
"You also bid on my brand name — won't that drive up my click prices?"
Honest answer: in search, a publisher ad can appear next to your own. So we won't claim there is zero interaction. Two points matter:
- The click budget is paid by the publisher — not by you. You only pay once a sale is confirmed.
- Your branded searches are being worked anyway: by marketplaces, comparison sites and competitors. In that case it is better that the click ends up in your shop.
Shopping/CSS works differently: there, only one bid for your products enters a given auction — you are not bidding against yourself.
"And what if my own campaigns would have got that sale cheaper?"
Possibly. The difference is not in a single sale — it is who fronts the media budget:
And when a sale does happen, you know your cost share upfront: 14.3% of the net basket — fixed, no matter how many clicks it took.
The publisher carries the media-budget risk. You only pay once the sale is made.
"Do you count sales where someone merely saw an ad?"
No. Post-view is never used — Selecdoo rules it out on the technical level. Commission only arises from a real click on an ad plus a confirmed sale in your shop.
No post-view. Excluded by design.
"Are you just going after my existing customers?"
No. The social channel runs on lookalike audiences: people who resemble your best customers but don't know your shop yet. The goal is new customers.
That takes a few weeks of pixel data — which is why the channel is switched on after search and shopping. And since the publishers only earn on a sale, they have no interest in burning budget on audiences that go nowhere.
Lookalikes bring you buyers who don't know your shop yet — on publisher budget, billed only when a sale happens.
At the end of the day, only one question matters.
Does your store make more money with all channels running together than it did before?
Your Google Ads agency keeps optimising your existing budget. The publishers risk their own media budget. You compare the overall revenue and cost impact — and only scale the channels that make economic sense for you.
You can start this small
You don't have to restructure anything or hand anything over. A four-week test is enough.
- 1Grant shop access once. Selecdoo connects the feed and the pixel.
- 2Let it run for four weeks — on publisher budget, at no cost to you.
- 3Compare the numbers. Keep, scale or switch off channels individually.
No contract, no upfront cost, your existing commission rate. If you work with a Google Ads agency, they don't have to hand anything over — the additional channels run alongside and should be measured by the numbers just like any other performance channel.
FAQ
Working together
All channels together
Search, shopping, display and editorial reach can be combined. Each of these channels runs on top of your existing setup, on partner budget, and is billed per sale — with the fixed-price packages, at the price agreed in advance. None of it replaces what you already do today.
What each channel contributes
- Shopping via CSS and the Microsoft network capture demand that already exists.
- Display placements on comparison platforms decide who makes the shortlist.
- Editorial reach and newsletters create demand that would not have existed otherwise.
- Fixed-price packages secure a firm date when a launch or peak week is coming up.
At the end of the day, only one question matters.
