Rotating offer slots
A slot is a placement on your site that automatically rotates the best-paying eligible offer for each visitor.
The simplest way to earn is to grab embed code for a specific offer and paste it on your site. That works, but it means you have to manually swap snippets when you want to try different offers. Slots solve this: paste one snippet, and we automatically rotate the best-paying eligible offer for each visitor.
How slot selection works
Each time a visitor loads your page, the slot snippet asks our ad server: "Of all the offers that fit this slot's rules, which one has the highest expected earnings for this visitor?" We pick the winner based on:
- The visitor's country, device, and language (we won't serve a US-only offer to someone in Canada).
- The slot's allowed offer types (you decide which types - coreg, CPA, CPC, CPM - are eligible).
- The offer's bid, weighted by its type's typical engagement rate (a $1 coreg with ~20% opt-ins is worth more than a $1 CPC with ~1% click rate).
Creating a slot
- Click Slots in the left nav.
- Click + New slot.
- Pick a friendly name (just for you - visitors never see it) like "Sidebar - right rail" or "Article footer".
- Pick which site the slot is on.
- Choose which offer types you'll allow. This is the important decision.
- Save. You'll get a unique slot key - copy it from the Slots list or click Get code.
Choosing the right offer types
The default is "all types allowed" - coreg, CPA, CPC, and CPM. That maximizes the eligible pool, but it means a coreg yes/no widget might appear where you'd rather see a banner. Tune the type filter to the placement:
- Sidebar / banner-style placement: uncheck Coreg. You only want display offers there.
- Post-signup / thank-you page: coreg-only is often best. The user is already in a "what's next" mindset, and yes/no opt-ins outperform banners in that context.
- Inline article / content area: all types fine. Display ads work; if a coreg offer wins the auction it'll render inline too.
Slot snippet vs. specific-offer snippet
You can still grab a snippet for a specific offer (see Installing the embed code). The difference:
| Use this when… | Specific-offer snippet | Slot snippet |
|---|---|---|
| You want a specific advertiser's offer in a specific spot | ✓ | - |
| You want to "set and forget" - rotate automatically | - | ✓ |
| You want to test which offers earn best on a given page | - | ✓ |
| You want to swap offers without touching your site's HTML again | - | ✓ |
For most publishers, a slot snippet is the better default. The specific-offer snippet is mostly useful when an advertiser has asked for a guaranteed placement, or when you're A/B testing offers manually.
The site key is in the slot
You don't need to manage site keys yourself when you use slots - the slot already knows which site it's on. Just paste the slot snippet on that site and earnings get attributed automatically.
Managing a slot
Click any slot's name on the Slots page to open its detail view. From there you can:
- See which offers can serve right now - a live preview of every active campaign that matches the slot's type filter, sorted by payout. Useful for sanity-checking your filter before going live.
- Get code - copy the slot snippet for this placement.
- Edit the slot's name, parent site, or allowed offer types. Changing the type filter is the easiest way to fix "wrong kind of ad showing up in this spot" without recreating the slot.
- Disable or Enable the slot with one click. A disabled slot stops serving immediately; the snippet on your page renders nothing until you flip it back.
Seeing what's serving
The Reports page can pivot earnings By offer so you can see which offers are winning the auction in each slot. If a slot is dominated by one offer, that's a sign the rest of your eligible pool isn't competitive - try widening the type filter to bring more offers into the auction.
