How Landing Page Relevance Cuts CPC and Boosts ROAS

The most boring lever in PPC is also one of the most profitable: landing page relevance.

‍

Not the fun stuff like new bidding strategies or shiny AI tools. Just the very simple question:

When someone searches a specific thing, does the page you send them to actually feel like it was built for that search?

‍

If the answer is “eh, kind of,” you are paying more per click than you should and leaving ROAS on the table.

‍

This post is for PPC managers and agencies who live inside Google Ads all day and want a clear link between:

Relevance → Quality Score → CPC → ROAS

‍

No fluff, just the mechanics and a practical way to fix it.

‍

1. The chain: relevance → Quality Score → CPC → ROAS

‍

Google does not hide what it cares about. For search campaigns, ad quality is driven by three things:

• Expected clickthrough rate
• Ad relevance
• Landing page experience

‍

Quality Score itself is just a 1–10 diagnostic, but those three components are used in the real-time ad auction. A higher score means your ad and landing page are more relevant and useful compared with other advertisers.

‍

Why you should care:

• Better quality lets you pay less for the same position or hold a higher position at the same bid.
• Lower CPC at the same conversion rate = instant ROAS lift.
• Higher relevance usually improves conversion rate as well, which makes the effect multiplicative.

‍

So if you improve landing page relevance, you are not just being a good UX citizen. You are literally buying cheaper, more profitable clicks.

‍

2. What landing page relevance actually means

‍

A lot of people hear “landing page experience” and think design prettiness. Google is much more practical.

‍

In its own documentation, it ties landing page quality to how useful and relevant the page is to the user, how easy it is to navigate, and how well it matches what the ad promised.

‍

In practice, relevance comes down to three things:

• Message match – The query, the ad, and the page all talk about the same problem or desire, using similar language.
• Intent match – Someone searching “how to automate onboarding emails” should not land on a generic “all-in-one marketing platform” homepage with twelve unrelated features.
• Experience quality – The page loads fast, is mobile friendly, and does not feel like a maze. Speed has a direct impact on both conversions and bounce rate; even a 0.1 second improvement in mobile load time has been shown to increase conversions and average order value across industries.

‍

When those pieces line up, you usually see “Above average” for landing page experience in Google Ads and your CPC quietly starts to drop.

‍

3. How bad relevance quietly kills your ROAS

‍

You do not need a complicated dashboard to spot relevance problems. The symptoms are pretty consistent:

• Many keywords showing “Below average” landing page experience or ad relevance
• You are paying noticeably more per click than industry benchmarks despite decent bids
• High bounce rate and low time on page from paid search, even when traffic is clearly high intent

‍

The worst part? On the surface, everything can look fine:

• Your ads mention the right keywords
• Your landing pages are not totally random
• The account is technically well structured

‍

But if twenty different high-intent queries all land on the same generic page, Google can see people bouncing, and your wallet pays for it.

‍

4. Mini-case: from generic lander to relevant funnel

‍

Let’s take a simplified example based on a real B2B SaaS account I’ve seen.

‍

Before

A mid-size SaaS company was bidding on:

• “b2b onboarding automation”
• “employee onboarding workflow tool”
• “hr onboarding software”

‍

All three keyword groups were pointed to the same generic product page.

‍

Quality Score sat around 5–6. CPC averaged 2.10. Conversion rate hovered at 3.5%. ROAS was… let’s call it “barely acceptable.”

‍

Why? Because the page was a feature buffet. No clear story for HR, no specific proof, and no attempt to speak to someone actively Googling onboarding problems.

‍

After

They rebuilt the funnel around relevance:

• Dedicated landing page focused just on HR onboarding automation
• Headline and hero copy mirroring the main keyword themes
• Social proof and examples all framed around HR and employee onboarding
• Clean form and faster page (images compressed, layout simplified)

‍

Result after a few weeks:

• Quality Score on main onboarding keywords: 5–6 → 8–9
• Average CPC: 2.10 → 1.30 (down ~38%)
• Conversion rate: 3.5% → 7.8%

‍

Even if you ignore anything fancy and look only at maths:

Cheaper clicks and more conversions per click = big ROAS jump.

‍

And the lever was not a new bidding strategy. It was landing page relevance.

‍

5. A practical playbook to make relevance work for you

‍

Here is a straightforward way to connect relevance to QS, CPC, and ROAS without turning it into a year-long project.

‍

Step 1 – Audit your keyword-to-page mapping

Open your search campaigns and look at how many high-intent keywords are pointing at the same landing page.

If one all-purpose page is doing the heavy lifting for dozens of different queries and use cases, you have your first problem clearly highlighted.

Cross-check with Quality Score components in the interface. If you see repeated “Below average” for landing page experience or ad relevance on those keywords, you have confirmation from Google itself that the experience is off.

‍

Step 2 – Cluster by intent, not just by syntax

Instead of obsessing over match types, think like a human:

• Which keywords are clearly the same problem phrased differently
• Which ones signal different roles (founder vs PPC manager vs HR)
• Which ones indicate different stages (research vs buy now)

‍

You do not need a landing page per keyword in every account, but you absolutely should have different pages for clearly different intents.

Example:

• “google ads landing page tool” → direct, solution-aware, wants a product
• “how to improve landing page quality score” → problem-aware, needs guidance first

‍

Sending both to the same page is lazy and expensive.

‍

Step 3 – Build or generate focused landing pages per cluster

For each key intent cluster, create a page that:

• Mirrors the main queries in your headline and subhead
• Focuses benefits and proof on that specific problem or role
• Has a clear, appropriate CTA (demo, trial, guide, calculator…)

‍

This is exactly the kind of work dynares’ landing page creator is built for: you define your templates and brand rules once, then generate tailored pages per keyword or cluster without dragging developers into it.

‍

You move from:

“We have two landing pages for 200+ keywords”

to:

“Every serious intent has a page that actually makes sense.”

‍

Step 4 – Fix the obvious speed and UX issues

Relevance is not just words. It is the experience around those words.

All the big studies say the same thing: faster sites convert better. A Deloitte and Google study showed that improving mobile site speed by just 0.1 seconds led to measurable increases in conversion rates and average order value across verticals.

‍

That matters twice in Google Ads:

• It improves your landing page experience component of Quality Score
• It directly boosts conversion rate, making your cheaper clicks even more valuable

‍

So while you are fixing relevance, also:

• Compress heavy images
• Kill unnecessary scripts
• Make the next step obvious above the fold

‍

You do not need perfection. You need fast enough that people do not bail before the page even loads.

‍

Step 5 – Measure impact all the way to ROAS

‍

Once new pages are live:

• Track Quality Score components over a few weeks
• Watch CPC trends on the updated keywords
• Compare conversion rate and ROAS before vs after

‍

Most decent guides on Quality Score point out that higher relevance and better landing page experience tend to translate to lower CPC and better positions over time.

‍

Tie that to your revenue numbers and you will have a very boring, very convincing internal slide that says:

“We made the landing pages actually relevant and ROAS went up.”

‍

6. Where dynares fits into all of this

‍

Everything above can be done manually.

You can:

• Brief designers
• Wait for devs
• Repeat for every new keyword cluster
• Juggle 20 versions of the same page across tools

‍

Or you can admit that as accounts grow, that approach simply does not scale.

‍

That is why you need dynares:

• You bring your keywords, brand guidelines and offers
• dynares generates landing pages (and matching ad copy) per keyword or cluster
• Pages stay fast, on-brand and easily editable by marketers
• Conversion uploads can be automated so Smart Bidding optimises for revenue, not just form fills

‍

The point is not to replace your strategy. The point is to make it realistic to give each high-intent keyword a relevant, high-performing landing page without creating a dev backlog that never ends.

‍

Closing thought

‍

If your CPC feels too high and your ROAS feels too fragile, start with the unsexy question:

“Does this keyword get the landing page it actually deserves?”

‍

When you fix that, you are not just improving Quality Score. You are buying cheaper clicks, converting more of them, and building a search funnel that feels good for users and for your P&L.
