One of the most common conversations I have before taking on a new Google Ads client follows the same pattern: spend has been increasing, click volume looks reasonable, but conversions are flat or declining. This is something I see regularly with North Wales businesses: the campaigns are running, the clicks are coming, but the website isn't doing its part. The instinct is to look harder at the campaigns. But when I check the data, the campaigns are often doing their job. The problem is what happens after the click.
Google Ads delivers traffic. What happens to that traffic is entirely down to the website. If the website experience is broken, unclear, or unconvincing, Google Ads doesn't fix that. It makes it more expensive. Every pound spent on advertising a poor conversion experience is a pound spent amplifying the problem.
I took on a client recently, a garden landscaping business in Denbighshire, who had been spending £900 a month for four months with three enquiries to show for it. The campaigns were actually well structured. Tightly themed ad groups, relevant keywords, good negative keyword coverage. The issue was the landing page: it loaded in 8.2 seconds on mobile, had no phone number visible above the fold, and the only form required name, email, address, phone number, and a description of the project. People were clicking, seeing a slow page with a demanding form, and leaving. We fixed the landing page, and enquiries in the following month went to 19.
The instinct when Google Ads underperforms is to question the ads. In my experience, the ads are often the least likely culprit. Look at what happens after the click first.
Google Ads is an amplifier, not a fix
The most useful way to think about the relationship between Google Ads and your website is that Google Ads is an amplifier. It takes what's already happening on your site and does more of it, faster, at cost. If 2% of your organic visitors convert, Google Ads will send more traffic and roughly 2% of those will also convert. If 0% convert, because the page is slow, the message is wrong, or the call to action is buried, Google Ads will amplify that too. More spend, more clicks, zero customers.
This means fixing a website problem by running more Google Ads is the wrong sequence. You fix the website problem first, confirm the conversion rate improves, then scale the paid traffic.
What actually causes the problem
In audits where traffic looks reasonable but conversions are low, the website issues I find most often fall into a few consistent categories.
The most common is a landing page that doesn't match the ad. An ad promising "emergency plumber North Wales" that sends traffic to a generic homepage, rather than a dedicated service page, creates an immediate mismatch. The visitor clicked because they had a specific, urgent need. A homepage that describes the business in general terms doesn't answer that need. They leave. You paid for the click.
Page load speed is another frequent culprit. It affects both conversion rate and Quality Score. A landing page that takes five seconds to load on mobile loses a significant portion of its visitors before they've seen anything. Google's own data consistently links load time to abandonment. If your page fails Core Web Vitals thresholds, you're losing traffic you've already paid for.
Some websites have no clear next step on the landing page. Contact information is in the footer. The phone number isn't prominent. The form requires too much information. People who arrived ready to enquire can't easily do it, and they don't persist. They look for someone else.
Then there's the question of whether the offer is competitive. If your pricing, delivery terms, or value proposition doesn't stand up against alternatives visible in the same search results, Google Ads traffic will highlight that gap rather than hide it. Visitors compare. If a competitor is offering a better deal or a clearer service, they'll close more of the same traffic you're paying to send.
Finally, trust. Particularly for service businesses, first-time visitors need signals that you're legitimate and capable. Reviews, case studies, industry memberships, clear contact information, and professional design: these are the signals that convert browsers into enquirers. A site without them leaves visitors uncertain, and uncertain visitors don't convert.
How to diagnose the problem before spending more
Before increasing a Google Ads budget, it's worth running a basic conversion diagnostic. The data you need is available in Google Analytics 4.
Start with landing page conversion rate: which pages is the traffic landing on, and what percentage are converting? A landing page with a conversion rate under 1 to 2% for targeted paid traffic typically has a website problem, not a traffic problem.
Then look at bounce rate and engagement rate. Are visitors leaving immediately, or are they engaging with the page? A high bounce rate on a paid traffic landing page points to mismatch between the ad and the page, or to load speed.
Also check the device breakdown: is performance consistent across desktop and mobile, or is mobile significantly worse? Many sites have desktop-optimised pages that perform poorly on mobile, where a large share of search traffic now comes from.
If you don't have conversion tracking set up, you can't do any of this analysis, and that's a foundational issue that needs fixing before anything else. You cannot optimise what you can't measure.
The right sequence
The practical sequence for getting Google Ads to work is not "start spending, fix the website if needed later." It's:
- Set up conversion tracking so you have data to work with
- Review the landing pages traffic will hit and address obvious issues (load speed, message match, clear CTA)
- Launch campaigns at a measured budget
- Identify which keywords and landing pages are converting and which aren't
- Fix the non-converting pages before increasing spend
This sequence feels slower at the outset, but it means that when you do scale budget, you're scaling something that works rather than scaling a leak.
What Google Ads can do
None of this is an argument against running Google Ads. When the website experience is right, Google Ads is one of the most effective ways to acquire new customers: it puts you directly in front of people who are actively searching for what you offer, at the moment they're looking.
The point is that the website and the advertising work together. Google Ads brings the traffic; the website converts it. Both parts have to work. Investing heavily in one while neglecting the other produces the frustrating result that many businesses experience: plenty of activity, no returns.
