A Quality Score of 5 can cost you 50-100% more per click than a QS of 8. On a keyword spending $5,000/month, that's $2,500-5,000 in excess costs.
Understanding the root causes is the first step to solving the problem.
Your ads don't closely match the keywords triggering them. Generic ads for specific keywords hurt Ad Relevance scores.
Historical CTR on your keywords is below what Google expects. This can be due to weak ad copy or misaligned intent.
Slow load times, thin content, or pages that don't match ad messaging hurt Landing Page Experience scores.
Too many keywords per ad group makes tight keyword-ad matching impossible. Structure affects relevance.
Well-intentioned fixes that often make things worse.
QS directly determines your actual CPC. It's not a vanity metric - it's a multiplier on every click you pay for.
QS has three components. Ad copy only affects Expected CTR and Ad Relevance. Landing Page Experience requires page improvements.
Tight ad-keyword relevance is impossible with broad ad groups. SKAGs or tightly themed ad groups are necessary for high QS.

Best practices to prevent this problem from occurring or recurring.
The impact is significant and compounding. Moving from QS 5 to QS 7 can reduce CPC by 20-30%. On a keyword spending $2,000/month at $4 CPC, that's $400-600/month saved - just from QS improvement. And better positions often improve CTR and conversion rates too. Across an account, QS optimization is often the highest-ROI activity you can do.
