Yes, landing page speed affects your Quality Score through landing page experience. Quality Score is Google's 1-10 keyword diagnostic built from expected click-through rate, ad relevance and landing page experience. Landing page experience rates how relevant and useful your page is for people who click. Google Ads Help advises advertisers with Average or Below-average pages to keep pages fast-loading and mobile-friendly, as described in Google's guide to landing page experience.

How speed fits into Quality Score
Quality Score has three inputs, and landing page experience is one of them. The other two are expected click-through rate and ad relevance, according to Google Ads Help on Quality Score. Google rates landing page experience as Below average, Average or Above average.
A slow page can drag that rating down even when your keywords and ad copy match. That matters because relevance alone does not save a slow page. A visitor who waits will leave before reading your offer.
Does the 1-10 score decide your ad position?
No, not directly. Google states the 1-10 Quality Score is an aggregated estimate of auction performance and is not used at auction time to determine Ad Rank, according to Google's Quality Score definition. Ad Rank determines eligibility and position.
Google calculates it first for eligibility and again for ranking among eligible ads. Think of the visible score as a diagnostic. The underlying experience still shapes the live auction, but the number itself is a report card.
What Google tells you to fix
For Average or Below-average pages, Google advises matching the page to the ad and keywords. Keep the message, headline and offer consistent from click to landing.
It also advises keeping the page mobile-friendly and fast-loading. Chrome sets good Core Web Vitals at LCP 2.5 seconds or less, INP 200ms or less and CLS 0.1 or less at the 75th percentile. Use these checks when a page is rated Average or lower:.
- does the headline match the ad promise
- does the page load fast on a mid-range phone
- can a visitor act without pinching, zooming or hunting
- does conversion rate rise after speed fixes, which Google suggests using as a proxy for quality
What slow pages cost advertisers
Slow pages waste paid clicks because visitors abandon before converting. Google found 53% of mobile visits are abandoned if loading exceeds 3 seconds. Bounce risk climbs fast with delay.
Google and SOASTA found mobile bounce probability rises 32% from 1 second to 3 seconds, 90% by 5 seconds and 106% by 6 seconds. For a WordPress, Drupal or custom front end, test the exact landing URL used in ads, not just the homepage. Fix the slow template first, then roll the fix to other campaign pages.
Frequently Asked Questions
Will a faster page raise my 1-10 Quality Score by itself?
It can help if landing page experience was the weak component. Check the three status columns to see whether expected click-through rate or ad relevance also needs work.
Should I test speed on desktop or mobile?
Prioritize mobile. Keep the page mobile-friendly and fast-loading, then confirm desktop does not regress.
