What does the "Other" category encompass in Optmyzr's PMax Channel Distribution?

The "Other" category includes a combination of channels served by Performance Max, such as Search, Gmail, Maps, and Discover. This classification is used when data does not fit neatly into the predefined categories of Shopping, Display, or Video within Optmyzr's analysis.

Why is there no Clicks data for some campaigns?

The absence of Clicks data for certain campaigns could stem from Performance Max's limitations regarding the information provided for different channels. While Cost data might be available, Click data for specific channels may not be accessible due to how Google Ads structures its reports.
