campaignCriterion.bidModifier returns 1 while UI shows 0%

[Tiana S.]

Hi there,

Question about the campaign_criterion.bid_modifier field. When requested from the API's ad_schedule_view resource, I get back 1 as value. But when checking the bid modifier in the ad schedule overview of the Google Ads UI, it's all 0%.

Is this intended or known behavior?

I can provide more information privately of course.

Thanks in advance!

The way it works in API is different from UI.  Here are examples of how the 2 values are mapped:

• UI value of 0% = API value of 1
• UI value of -10% = API value of 0.9
• UI value of 10% = API value of 1.1
• UI value of 800% = API value of 8

You can easily translate between the 2 values using the above logic.  This applies to all bid modifiers.

Apologies, the last bullet point should say an API value of 9!

Hi Tiana and Oliver,

I reproduced both your findings that the API returns the actual formula to calculate the adjusted bid based on a multiple of the standard bid, while the UI returns the  percentage differential between the standard bid and the adjusted bid. This appears to be working as intended.
