Plenty of UK businesses run Google Ads, watch the budget drain away, and can’t quite figure out what’s going wrong. The clicks are there. The campaign is active. But the enquiries aren’t coming. Nine times out of ten, it comes down to one of the same small set of problems. Here’s what they are and what you can do about them.
Your Keywords Are Too Broad
Broad match keywords give Google a lot of freedom to decide who sees your ads. Too much freedom, in most cases. A logistics company bidding on “van hire” can end up showing ads to people searching for “van hire apprenticeships” or “how to drive a van hire.” Those clicks cost money and produce nothing.
Switch your most important keywords to phrase match or exact match. Then open your search term report each week and add irrelevant searches to your negative keyword list straight away. Businesses that do this consistently tend to see real reductions in wasted spend within the first few weeks.
You’re Not Using Negative Keywords
Negative keywords tell Google which searches should never trigger your ads. Most businesses either haven’t set them up or haven’t touched them since the account launched.
Common terms to add as negatives straight away include “free,” “DIY,” “jobs,” “training,” “how to,” and competitor names if you’re not deliberately targeting them. Check your search term report every week and keep adding to the list as new irrelevant searches appear. This single habit makes a bigger difference to account performance than most businesses expect.
Your Ad and Your Landing Page Don’t Match
If someone clicks an ad for “IT support for construction companies” and lands on a generic homepage about everything you do, you’ve already lost them. They came looking for a specific answer. What they got was a front door.
Google measures the alignment between your ad, your keywords, and your landing page through Quality Score, a 1 to 10 rating. A higher score means lower costs and better ad placement. A lower score means you’re paying more per click for worse results.
Each ad group should link to a page that speaks directly to what the ad promises. If your existing pages don’t do that, it’s worth investing in dedicated landing pages or a stronger web design that converts paid traffic properly.
Conversion Tracking Isn’t Working
Without conversion tracking, you’re deciding how to spend your budget based on clicks alone. That’s a bit like judging how well a shop is doing by counting how many people walked past the window.
Tracking records the actions that matter: phone calls, form submissions, live chat contacts, and bookings. Many small business accounts have tracking that’s incomplete, recording one type of conversion but missing others, or not set up at all. Budget keeps flowing to campaigns that look active, not campaigns that generate leads.
According to WordStream’s 2025 Google Ads benchmarks, conversion data gaps remain one of the most common issues found in account audits. Fix this before you change anything else.
Your Ads Run at the Wrong Times
By default, Google runs your ads around the clock. For many UK businesses, that means paying for clicks at 2am from visitors who can’t reach anyone, bounce off the page, and don’t come back.
Check your hour-of-day and day-of-week reports under the Campaigns tab. You’ll see quickly when clicks convert and when they don’t. For most service businesses, concentrating budget on working hours delivers a better return without reducing the total number of leads. Tightening your ad schedule takes a few minutes and often has an immediate effect on cost per conversion.
You’re Not Testing Your Ad Copy
Running one ad variation and leaving it for months means you’ll never know what could have worked better. Headlines, calls to action, and offers all perform differently depending on your audience and what they’re searching for.
Responsive search ads let you add multiple headlines and descriptions. Google tests combinations and prioritises the ones that generate the most clicks. Use at least three headline variations per ad group. Test a price lead (“From £X per month”) against a benefit lead (“No contracts, cancel any time”). Small copy changes can shift click-through rates enough to improve your Quality Score and reduce what you pay per click.
You’re Focused on the Wrong Metrics
Impressions and clicks make an account look busy. They’re not the numbers that tell you whether a campaign is actually working.
What matters is cost per conversion, conversion rate, and return on ad spend. IAB UK reported that the UK’s digital advertising market reached £40.5bn in 2025, which means competition for attention is rising. More advertisers competing for the same searches means your budget has to work harder. You can only know if it’s working by tracking the outcomes, not the activity.
If your cost per lead is rising month on month and your conversion rate is flat, something in the campaign needs to change. You’ll only spot that trend early if you’re watching the right metrics.

Frequently Asked Questions
Why are my Google Ads getting clicks but no conversions?
The most common causes are a mismatch between your ad and the landing page it points to, keywords that are too broad, or conversion tracking that isn’t recording correctly. Start by checking your search term report and confirming that your tracking captures form submissions and phone calls.
What is Quality Score in Google Ads?
Quality Score is Google’s 1 to 10 rating of how relevant your ad, keywords, and landing page are to each other. A higher score lowers your cost per click and improves your ad position. A low score means you’re paying more than competitors for worse placement, even if your bid is the same.
How much should a UK small business spend on Google Ads each month?
There’s no fixed figure, as costs depend on your industry, location, and keyword competition. London CPCs tend to run 20 to 40% higher than the national average. Start with a budget you can maintain for at least three months, monitor cost per conversion, and adjust from there rather than making quick decisions on limited data.
What is a good conversion rate for Google Ads in the UK?
The average conversion rate on Google Search in the UK sits around 4 to 5% across industries, though this varies considerably. Lead generation businesses in less competitive sectors often achieve 6 to 8%. If your rate is consistently below 2%, it’s worth reviewing your landing page, keyword targeting, and ad relevance.
Should I manage my own Google Ads or use a specialist?
Self-managing works well if you have time to monitor the account weekly, review search term reports, and keep up with platform changes. If time is limited and every lead matters, a specialist will typically get stronger results more quickly through tighter management, proper tracking setup, and consistent testing.
How long do Google Ads take to start working?
You’ll see click data within the first couple of days. Reliable conversion data usually takes two to four weeks, as Google’s algorithm learns which searches produce results for your account. Avoid making large changes in the first few weeks. Let the account gather enough data before drawing conclusions or adjusting budgets.
