What it is
The post-click Quality Score component.
Landing page experience is Google’s rating of what happens after a user clicks your ad. It is the one Quality Score component that lives entirely outside the ad platform — and usually the one most in need of attention.
Every keyword in Google Ads receives a landing page experience rating alongside its expected CTR and ad relevance ratings. Together, the three ratings combine into the 1–10 Quality Score. Landing page experience measures whether the page a user arrives at is relevant to the query, loads quickly, works well on mobile, and communicates clearly who you are and what you offer. It is the only Quality Score component that responds to changes made outside of Google Ads itself.
Because landing-page changes propagate through Google’s crawler and re-evaluation pipeline within days rather than weeks, landing page experience is the fastest Quality Score component to move. A page-speed fix, a headline rewrite, or a mobile-layout cleanup typically lifts the rating from below average to average within 7–14 days, and from average to above average within 14–30 days if the other signals remain stable.
