Improve Your Google Ads Quality Score: How to Lower Your CPC in B2B

Your Google Ads quality score is the quiet lever behind your cost per click: the higher it sits, the less you pay per click and the higher your ad appears, without raising your bid. The short version: improve the relevance between your keyword, your ad and your landing page, and your cost per lead drops by itself. In this article we explain how the score determines your position and your cost through the Ad Rank formula, and which buttons you can actually press to pull more qualified B2B leads out of the same budget.

What is Quality Score in Google Ads?

Quality Score is an estimate that Google makes of the quality of your ads and keywords, expressed on a scale from 1 to 10. That score is built from three components: the expected click-through rate (CTR), the relevance of your ad to the keyword, and the experience on your landing page (Google).

Important to understand: the Quality Score you see in your account is a diagnostic number. It is not a dial you turn up directly, but a thermometer that measures how well your three underlying components are in order. So you always improve the score through those components, never directly.

With Google Ads, this is exactly why two companies with the same budget get completely different results. Whoever is more relevant pays less and ranks higher. For background on terms like SEA and PPC we have separate explainers. You will also find a concise definition in what is a Quality Score in Google Ads.

How does Quality Score determine your cost per click and position?

This is where the real value sits. Google does not decide your ad position purely on who bids the most, but through the Ad Rank formula. Simplified, it comes down to:

Ad Rank = maximum bid x Quality Score (Google)

That means two things that change your entire cost picture:

• You can overtake a higher-bidding competitor. Say a competitor bids more than you, but your Quality Score is higher. Your Ad Rank can still come out on top, and you sit above them for less money.
• You pay less per click with a higher score. Because the score sits inside the formula, a higher Quality Score means a lower CPC and a higher position (WordStream). On expensive keywords, that can be the difference between an affordable and an unaffordable cost per click.

Run the maths at B2B scale. If you buy hundreds of clicks a month on expensive keywords, every euro less per click adds up fast. And the beauty is: your cost per lead drops without touching your bid or giving up visibility. Beyond your Quality Score there are more levers to lower your cost per click. That is exactly the kind of optimisation we steer on, because it improves your ROAS instead of just your click volume.

What Quality Score do you need?

There is no official threshold, but in practice a minimum score of around 7 is recommended for cost-efficient campaigns. Anything lower means you are structurally paying more than necessary, or your ads are shown too little.

WordStream analysed data from hundreds of advertisers and found that your cost per conversion drops by roughly 16% on average for every point your Quality Score sits above the average of 5, a pattern that also shows up in Semrush’s analysis of Quality Score. Treat that as direction, not a guarantee: it varies by sector, by keyword and by level of competition. But the logic holds: being more relevant is rewarded, being irrelevant is penalised.

Our honest nuance: do not chase a 10 on every keyword. A score of 7 or 8 on your most important, purchase-intent keywords delivers more than a perfect 10 on a term that produces no leads anyway. Steer on the keywords that bring in customers, not on a dashboard number.

How do you improve your Quality Score in practice?

The score follows from three components, so that is where you intervene. Google itself lists three ways to improve your Quality Score. Below are the three levers, and what they mean in concrete B2B terms.

1. Raise your expected CTR

Google looks at whether people click your ad when they see it, a component Google calls expected click-through rate. Strong, specific ad copy that picks up the keyword scores better than a vague one. If you want to go deeper, read how to raise your CTR.

• Include the keyword in your headline and description.
• Be concrete about what you offer and for whom (B2B, not consumers).
• Test variants and pause what does not work.

2. Improve ad relevance

This is about the match between keyword and ad. The biggest mistake we see: too many wildly different keywords in one ad group, so no single ad really fits.

• Group tightly: thematic ad groups with a handful of closely related keywords.
• Write one ad per group that matches those keywords exactly.
• Filter out noise with negative keywords, so your ad does not appear on irrelevant searches.

3. Optimise the landing page experience

The page you send people to counts. Someone who clicks on “HR software quote” and lands on your general homepage does not get a relevant experience, and you see that back in your score. Google describes landing page experience as a separate factor within Quality Score.

• Make sure the landing page matches the keyword and the ad in substance.
• Make sure the page loads fast and works on mobile.
• Make the next step crystal clear: one obvious call to action.

A strong landing page improves not just your Quality Score, but also your conversion rate. For Facilicom, exactly this kind of optimisation delivered a 25% media saving, without the number of enquiries dropping.

When is working on your Quality Score not worth it?

Honest advice is part of the job. Sometimes Quality Score is not your problem.

If you are in too small a market, or on keywords without real purchase intent, a higher score will not fix that. You will still be buying traffic that does not convert, just slightly cheaper. In that case the real question is whether Google Ads is the right channel at all, or whether your budget is better spent elsewhere.

And if your entire account is structurally underperforming, tinkering with individual scores is treating symptoms. Then restructuring your campaigns and account setup makes more sense. That is work a Google Ads agency or outsourcing your management can take on, provided the agency steers on cost per lead and not on your media budget.

Frequently asked questions about Google Ads Quality Score

What is a good Quality Score in Google Ads?

A score of around 7 or higher works as a benchmark for cost-efficient campaigns. More important than a perfect 10 on every keyword is a strong score on the keywords that actually generate leads.

Does a higher Quality Score really lower my cost per click?

Yes. Because the score sits inside the Ad Rank formula (Ad Rank = max bid x Quality Score, according to Google), a higher score means a lower CPC and a better position (WordStream). So you can rank above a competitor who bids more.

How much can I save per extra Quality Score point?

WordStream research points to a drop in cost per conversion of roughly 16% per point your Quality Score sits above the average of 5. Treat that as an indication: the real effect depends on your sector, keywords and competition.

Can I adjust my Quality Score directly?

No. The score is a diagnostic number. You always improve it through the three underlying components: expected CTR, ad relevance and your landing page experience.
