Why can't I see suggestions in the Non Converting Keywords optimization?
It might be due to the following reasons:
Keywords that haven't received enough traffic to convert will not show up, even if they have zero conversions.
The keywords may not match the selected filter criteria. You can update the filters to see if it's the filters or the data which might be causing it. You can also enable the Turbo Mode to view more suggestions. In the Turbo Mode, the system lowers the threshold used to recommend suggestions. For example, in the Non-Converting Keywords optimization, you'll see all keywords that received at least 20 clicks but no conversions. *The Turbo Mode is not available for Microsoft Ads.
Our optimizations have been set up with intelligent threshold levels in order to make accurate suggestions for your account. These threshold levels squeeze out only the suggestions which match all the criteria. Microsoft accounts may have fewer or no suggestions often, as these accounts have much less traffic compared to Google Ads accounts, and therefore may not be able to match the threshold levels.
