How Quality Score Actually Works
Google scores every keyword on a 1-10 scale based on three factors: Expected CTR, Ad Relevance, Landing Page Experience.
Higher Quality Score → lower CPC + higher Ad Rank at the same bid.
Going from QS 4 to QS 8 typically cuts CPCs by 40-60%.
Tactic 1: Tighten Ad Groups
One theme per ad group. 5-15 keywords max. All variations of one core query.
Loose ad groups (50+ keywords spanning 3 themes) wreck Quality Score.
Tactic 2: Match Ad Copy to Keyword
Include the exact primary keyword in the H1 of one responsive search ad headline.
Include it in the landing page's H1 too. Consistency = Ad Relevance.
Tactic 3: Use Dynamic Keyword Insertion (Carefully)
DKI can boost CTR by inserting the searched keyword into your ad.
Risk: insert can produce grammatically broken or off-brand text. Test carefully.
Tactic 4: Improve Landing Page Experience
Page loads in <2.5 seconds.
H1 matches the ad copy (and the keyword).
Mobile-friendly, no aggressive popups.
Single clear CTA above the fold.
Tactic 5: Add Ad Extensions
Sitelinks, callouts, structured snippets, image extensions.
Each extension adds Ad Relevance signals + boosts CTR.
Aim for 6+ extensions per campaign.
Tactic 6: Pause Low-QS Keywords
Keywords with QS 1-3 likely won't recover.
Pause them. Build new tightly themed ad groups with better-matched keywords.
Tactic 7-9: A/B Testing, Negative Keywords, Bidding Patience
Continuously test ad variants — Google needs 4+ to optimise effectively.
Aggressive negatives clean out irrelevant traffic, boosting CTR.
Don't bid too low — sub-page-1 ads can't build CTR data.

Frequently Asked Questions
What is a good Google Ads Quality Score?
7-10 is good. 5-6 is average. 1-4 means you're overpaying significantly. Most well-managed accounts target 7+ on primary keywords.
How long does it take to improve Quality Score?
2-4 weeks after structural changes. QS updates based on rolling 30-day CTR data. Patience required — don't make multiple changes simultaneously or you can't isolate what worked.
Does Quality Score affect Performance Max?
Indirectly. PMax doesn't show keyword-level QS but uses similar signals (asset quality, landing page experience, audience match). Improving these helps PMax efficiency.
Is Quality Score still important in 2026?
Yes. Despite increasing AI automation, Quality Score remains a critical lever for CPC reduction in Search campaigns. PPC managers who ignore it overspend by 30-50%.
