The short answer
Search themes are the one place a person tells Performance Max, in words, what an asset group is for. Without them Google infers it from the page, the images and the feed. Oppy lists the asset groups with no search theme.
Why it matters
When Google infers the topic, it usually gets close. When it does not, there is nothing to point at: no keyword, no theme, only a campaign buying searches nobody chose.
A handful of themes per group, in the words customers use, gives Google a direction and gives you something to adjust.
How Oppy decides
The check runs on accounts with Performance Max asset groups whose signals could be read.
Checks that weigh money or clicks judge what they find on your own account's numbers, not on one figure applied to every account, so what counts as a problem on a small account is not the same on a large one. Checks on settings read how the account is set up.
When there is too little to go on, the check says so instead of guessing. A finding always comes with the rows behind it, so you can read the evidence before you decide.

Check it yourself in Google Ads
- In Google Ads, open a Performance Max campaign, then Asset groups.
- Open each group and look at Signals.
- Check for Search themes, and note the groups with none.
- Note whether those groups have audience signals instead.
What to do about it
Add search themes to each asset group, in the words your customers type for what that group sells. Google allows up to 50 per group, and a short list of the main ones is a good start.
Check the campaign's search terms after a few weeks to see whether it follows them.
