A high Quality Score in Google Ads means lower costs and better ad placement. One factor that directly affects it, and is frequently left unaddressed, is the relevance of the landing page your ads point to.
Most advertisers focus their optimisation energy on ad copy, adjusting headlines, testing descriptions, tweaking bids. Landing pages get less attention because they feel harder to change. In my experience, that's exactly backwards. Landing page relevance is the component of Quality Score that moves the most when you fix it, and the gains hold longer than any bid adjustment.
Why Quality Score matters
Quality Score is Google's rating system for the quality and relevance of your ads and keywords, on a scale of 1 to 10. The higher the score, the lower the cost per click and the better the ad placement you can achieve.
It's based on three components. Expected clickthrough rate is how well your ad is likely to perform based on past data. Ad relevance measures how closely your ads match the searcher's intent. Landing page experience covers the quality and relevance of the page the ad sends people to.
Since landing pages directly affect that third component, getting them right is worth treating seriously. If you want to understand how Quality Score feeds into the actual auction outcome, specifically how a higher score translates into lower CPCs against higher-bidding competitors, How a Google Ad Auction Works explains the formula in plain terms.
How landing pages affect Quality Score
Google wants to provide a good experience by showing relevant ads that lead to useful pages. If your landing page doesn't match the searcher's query and intent, you'll be penalised with a lower score.
A poor landing page can drag Quality Score down in several ways: content that's irrelevant to or thinner than what the search query implies, keywords that don't match what the searcher typed, a low-quality user experience, high bounce rates, or slow page load times.
When the landing page is properly optimised for the keyword, it signals relevance to Google and improves the landing page experience component, which raises the overall score.
Tips for optimising landing pages
-
Include the keyword in the title and headings: the keywords you're targeting should appear naturally in your headline title tag and H1/H2 headings. This signals relevance to Google. Don't over-optimise, as keyword stuffing will get you penalised.
-
Make sure the content matches the user's intent: analyse the searcher's intent for your keyword and create useful, relevant content around it. Answer their questions and provide genuine value. If the page deviates too far from what they were looking for, bounce rates increase.
-
Pay attention to on-page SEO: meta descriptions, image alt text, and structured data markup all contribute to how Google reads the page. Proper on-page SEO signals a high-quality page.
-
Improve page speed and mobile experience: slow load times lead to higher abandonment. Use caching, compression, and efficient code to optimise speed. Also make sure the page is mobile-friendly and loads quickly on all devices.
-
Include related keywords naturally: secondary keywords and semantically related terms throughout the content show Google relevance for a broader range of queries. Don't force it. Natural is the goal.
-
Track analytics and optimise: use Google Analytics to identify problem areas like high bounce rates. A/B test different landing page versions to improve conversions.

What this looks like with real accounts
I've seen this pattern more times than I can count. A business owner comes to me reporting that their Quality Score is "fine," usually meaning it's averaging 6 or 7 across the account. But when I pull up the keyword-level data, there are three or four keywords driving the majority of their spend sitting at 4/10, and the breakdown tells a consistent story: landing page experience is rated "Below average." They'd been monitoring the average number, not the outliers.
The keywords they actually needed to win on, the commercial-intent terms with the highest CPCs, were the ones being penalised most. One client was paying over 60% more per click on their primary keyword than a competitor with a similar bid but a better-aligned landing page. We rebuilt the landing page to match the keyword's intent specifically. Same core service, but the headline, the opening paragraph, and the CTA all spoke directly to the search query. Quality Score moved from 4 to 7 within three weeks. The CPC reduction covered the cost of the work in the first month.
How to diagnose your current landing page Quality Score
Go to Keywords in your Google Ads account and look for the Quality Score column (you may need to add it via the Columns menu). Click on the Quality Score for any keyword and Google shows the three components, expected CTR, ad relevance, and landing page experience, each rated as "Above average," "Average," or "Below average."
If landing page experience is rated "Below average" on keywords with meaningful spend, that's your signal to act. A below-average rating increases the CPC you pay relative to your ad position. Fixing it produces a CPC reduction without changing bids.
What "landing page experience" actually measures
Google doesn't publish the exact formula, but the signals that feed into this component include relevance (does the page content match what the searcher was looking for?), page speed (use Google's PageSpeed Insights to check Core Web Vitals), mobile usability (most local search happens on mobile, so if navigation is difficult on a phone, bounce rates will be high), and transparency (pages without contact information, privacy policies, or clear business identity can score lower).
The practical sequence
If you want to improve landing page experience scores for your key keywords:
- Check the Quality Score column and identify keywords rated "Below average" on landing page experience
- Open the landing page those keywords send traffic to
- Search the keyword in Google and look at what the top 3 organic results cover: this is what Google considers relevant for that intent
- Check whether your page covers the same ground with comparable depth and specificity
- Run the page URL through Google's PageSpeed Insights
- Check on mobile: navigate through the page as a user would
Then make improvements in order of impact: relevance mismatches first, speed second, usability third. Recheck Quality Scores after 2 to 3 weeks.
The CPC impact
A keyword moving from Quality Score 5 to Quality Score 8 can reduce CPC by 30 to 50% for the same ad position. Lower-quality advertisers need to bid significantly more to hold the same position. Well-optimised landing pages are a form of cost reduction, one that doesn't require cutting exposure or reducing bids. For smaller businesses in North Wales competing against better-funded advertisers, improving landing page relevance is often the most practical way to close the gap without increasing spend.
