15 DATA-DRIVEN GOOGLE ADS KEYWORD OPTIMIZATION STRATEGIES FOR MAXIMUM ROAS

1. Skip keywords with single-conversion history

2. Skip low-volume, low-intent search terms

3. 1-click/1-conv keywords lack enough data

4. Low-volume bidding often drains budget fast

5. Over-bidding increases CPC, not conversions

6. Random conversions shouldn't drive decisions

7. Non-relevant keywords can't scale profitably

8. "Halo effect" conversions don't prove keyword ROI

9. Avoid managing 200+ keyword "micro" lists

10. Focus on high-intent, high-volume queries

11. Apply filters: 30 days, 20+ clicks, 2+ conv

12. Verify keyword intent directly on the SERP

13. Target high CPC for optimization, not removal

14. Never optimize solely for low CPA

15. Use Exact/Phrase for proven top performers
