On the Search Terms tab, click Suggest with AI. The AI reviews the terms that have appeared and haven't been added yet (prioritizing the 50 with the most clicks), checks the campaign's landing page when available, and classifies each term: add it as a positive keyword or as a negative, with a suggested match type. The suggestions appear in a list where you can review them, change the action or match type for each item, and then click Apply selected. Positive keywords go into the ad group where the term appeared, and negatives are added at the campaign level. At the end, the system shows how many were applied successfully.
