Campaigns using RTB and Prebid integrations support a set of bidding rules that give you enhanced control over both the price you receive from demand partners and the behavior of outbound bids.
How to Add a Bidding Rule
To add a bidding rule:
-
Go to the RTB / Prebid campaign.
-
Navigate to Basic Settings > Bidding Rule.
-
Click + Rule.
-
Select the desired rule.
-
Click Save.
Available Bidding Options
1. Bid Pricing Rules (Ad Request Level)
-
Min/Max Bidfloor
-
Acts as a pre-filter at the ad request level.
-
Applied before any other rules (e.g., override floor).
-
Ad requests outside this range are filtered out before proceeding further.
-
2. Response Bid Rules (Bid Response Level)
-
Min/Max Response Bid
-
Applied at the response level.
-
Filters incoming bid responses based on the specified bid value range.
-
3. Fixed Floor
-
All incoming bids will be overwritten with the fixed value you set.
-
Example:
-
If you set $5, all bids will be sent to demand as $5, regardless of the original bid value (even if your supply partner sends a higher bid, the outbound bid will be always $5).
-
4. Override Floor
-
Only bids below the specified value are overwritten.
-
Higher bids remain unchanged.
-
Example:
-
You set $5. Incoming bids:
-
$2 → overwritten to $5
-
$5 → unchanged
-
$7 → unchanged
-
-
5. Add to Floor Price
-
A fixed amount is added to all incoming bids.
-
Example:
-
You set $5. Incoming bid is $2 → outbound bid becomes $7.
-
How These Rules Work with Tag-Based Supply Sources
When you connect tag-based supply sources to an RTB/Prebid campaign:
-
With "Fixed CPM/Floor price" pricing type - the system uses the advertiser floor CPM (defined on the supply source) as the base for all incoming bid requests.
Example Scenario
You set $5 as the minimum bidfloor, but the supply source has an advertiser floor CPM of $2:
-
All requests below $5 (e.g., $2) will be filtered out.
To Fix This, You Have Two Options:
-
Increase the advertiser floor CPM on the supply source to $5
-
Use the Override Floor set to $5 on the campaign
-
Requests under $5 will be overwritten to $5
-
Requests of $5 or more will remain unchanged
-
- With "Share of revenue" pricing type - the system will use minimum possible bid of $0.01 (since there is no inbound bidfloor)
- With "Dynamic floor" - the system will sends bidfloor dynamically based on the inbound ad request.
Important Best Practice
Do not use the Min Bidfloor and Override Floor together.
Why?
-
If you set both to $10:
-
The Min Bidfloor filters out all requests under $10
-
The Override Floor never gets a chance to apply
-
Recommended Approach:
-
If your goal is to only send requests at or above $10, use Override Floor = $10 only.
-
All requests below $10 will be adjusted
-
No requests will be filtered out
