Yes, this happens often. Even if you follow Google’s asset recommendations, Responsive Search Ads may still show “Poor” strength due to:
Low asset variety (similar headlines)
Missing keywords in key positions
Not pinning important CTAs
Overuse of dynamic keyword insertion
Google's scoring not always reflecting real performance
Fix Tips:
Use diverse, unique headlines
Include main keywords in multiple spots
Pin a CTA or offer in headline 1 or 2
Focus on actual performance (CTR, conversions) — not just strength score
If your ads perform well, you can safely ignore the “Poor” label.
