What Actually Improves Google Ads Quality Score in 2026?

Quality Score is a diagnostic, not a lever

Quality Score doesn't directly control your costs — it's a reported summary of three underlying factors Google is already using to determine your ad rank. Chasing the number itself is less useful than fixing what it's actually measuring.

The three real components

• Expected click-through rate — whether your ad is likely to get clicked given your keyword and position
• Ad relevance — how closely your ad copy matches the intent behind the keyword
• Landing page experience — whether the page a user lands on delivers what the ad promised, loads quickly, and is genuinely usable

What actually moves each one

• For expected CTR: tighter ad groups with fewer, more relevant keywords per ad, so your copy can speak directly to search intent instead of covering too many topics at once
• For ad relevance: mirror the actual language of the keyword in your headline, not just a generic value proposition
• For landing page experience: page speed, mobile usability, and message match between ad copy and headline are the biggest levers — not vague "trust signals"

What doesn't move it much anymore

• Keyword insertion tricks without genuine relevance behind them
• Generic landing pages that technically load fast but don't match what the ad promised
• Obsessing over the visible Quality Score number in the interface rather than the underlying CTR, relevance, and landing page metrics feeding it

The bottom line

Quality Score improves as a byproduct of tighter targeting, honest ad copy, and a landing page that actually delivers on the ad's promise. Treat it as a symptom to diagnose, not a number to directly manipulate.
