Ask How do you approach keyword expansion in a Google Ads campaign that has plateaued?

[Brajet]

When a campaign stops growing, keyword expansion can help reach new searches and audiences. A good approach is reviewing search term reports, competitor ideas, and related topics connected to the product or service. New keywords should still match user intent closely so traffic remains relevant. Testing small groups of keywords first can help identify opportunities without wasting budget. Growth often comes from finding useful searches that were previously overlooked. What do you think is the most reliable source for finding new keyword ideas in Google Ads?
