Publisher Bidding allows you to adjust your CPC bids for individual publishers, giving you greater control over how your budget is allocated across your inventory. You can increase or decrease your bid for specific publishers based on their performance, or block publishers entirely from serving your campaign.
This feature helps optimise campaign performance by allowing you to invest more in high-performing publishers while reducing spend on lower-performing or less relevant inventory.
Enabling Publisher Bidding
Publisher Bidding is not enabled by default. It must first be activated by your Account Manager and can be enabled at either the Account level, Campaign level, or both.
Account-Level Publisher Bidding
When enabled at the account level, publisher bid adjustments apply across all campaigns within the account.
Navigation:
MyDianomi → Inventory → Supply Manager → Publisher Bidding
Use account-level bidding when you want to apply consistent publisher bid adjustments across your entire account without configuring each campaign individually.
Campaign-Level Publisher Bidding
When enabled at the campaign level, publisher bid adjustments apply only to the selected campaign.
Navigation:
MyDianomi → Ad Manager → View More → Publisher Bidding
Campaign-level bidding is ideal when individual campaigns have different objectives or require different optimisation strategies.
Using Both Account and Campaign-Level Bidding
Publisher Bidding can be enabled at both the account and campaign levels simultaneously.
When both are enabled:
- Account-level adjustments act as the default settings across all campaigns.
- Campaign-level adjustments can be applied to individual campaigns where different bidding behaviour is required.
- Campaign-level adjustments always take precedence over account-level adjustments for the same publisher.
This allows you to maintain consistent bidding rules across your account while making campaign-specific exceptions where necessary.
Reviewing Publisher Performance
Publishers are displayed based on the amount of traffic they have delivered to your campaigns, making it easier to identify your most significant traffic sources.
By default, publisher data is displayed for the last 30 days.
You can adjust the reporting period by selecting a different end date to review publisher performance over your preferred timeframe.
Adjusting Publisher Bids
You can increase or decrease your CPC bid for individual publishers using percentage-based adjustments.
For example:
| Publisher | Bid Adjustment |
| CNN | +25% |
| AP News | −15% |
Positive adjustments increase your competitiveness on a publisher, while negative adjustments reduce your bid without removing the publisher entirely.
Blocking Publishers
If you no longer wish to receive traffic from a specific publisher, you can block it with a single click.
Blocked publishers will no longer be eligible to serve your campaign until they are unblocked.
Publishers can be blocked or unblocked at any time.
Removing a Publisher Bid Adjustment
To delete an existing publisher bid adjustment:
- Edit the publisher's Price Adjustment.
- Tick Delete Adjustment.
- Click Save Changes.
Deleting the adjustment removes the custom publisher bid and returns bidding behaviour to the applicable default.
Important
If you set a 0% bid adjustment at the campaign level, this still counts as a campaign-level override and will take precedence over any account-level adjustment for that publisher.
If your intention is to revert to the account-level publisher bid, do not set the adjustment to 0%. Instead, delete the campaign-level adjustment so that the account-level setting can apply again.
Why Use Publisher Bidding?
Publisher Bidding allows you to optimise spend based on publisher performance.
Common use cases include:
- A publisher consistently generates strong conversion rates, so you increase its bid by 50% to win more traffic.
- Several publishers closely align with your target audience, so you increase their bids by 40% to maximise exposure.
- Another publisher delivers traffic but has a poor conversion rate, so you reduce its bid by 15% to improve efficiency.
- A publisher is not relevant to your campaign, so you block it completely.
Using publisher-specific bid adjustments enables you to allocate more budget to inventory that delivers the strongest results.
Measuring Publisher Performance
To understand how individual publishers are performing, you can:
- Use the Publisher Name macro, which passes the publisher name as one of your UTM parameters, allowing publisher-level analysis within your analytics platform.
- Enable Server-to-Server (S2S) Conversion Tracking, allowing publisher performance to be viewed directly within MyDianomi.
Using one or both of these methods makes it easier to identify which publishers are driving the best engagement and conversions, helping you make more informed bidding decisions.
Important: Combined Bid Adjustments
Publisher Bidding and Device Bidding are multiplicative, meaning their percentage adjustments are applied sequentially rather than independently.
For example:
- Base CPC: 1.00
- Desktop Device Adjustment: +100% → CPC becomes 2.00
- Publisher A Adjustment: +100% → CPC becomes 4.00
Both adjustments are applied together, resulting in a final bid that is four times the original base CPC.
When configuring multiple bid adjustments, keep this multiplicative behaviour in mind, as combined increases can have a significant impact on your effective bid.
