Keyword problems
The most common reason Google Ads campaigns don’t convert is that they’re targeting the wrong keywords — specifically, keywords that attract informational intent rather than commercial intent. Someone searching “what is SEO” is learning, not buying. Someone searching “SEO agency London pricing” is about to make a decision. These two searches are not equally valuable, and bidding equally on both is a waste of budget.
The other keyword problem is excessive use of broad match without proper negative keyword management. Broad match gives Google enormous latitude to match your ads to tangentially related searches. Without rigorous Search Terms Report analysis and negative keyword additions, you can easily spend 40–60% of your budget on completely irrelevant traffic.

Landing page mismatch
Message match between your ad and your landing page is one of the most overlooked conversion factors in PPC. When someone clicks an ad for “emergency plumber London” and lands on a homepage with a generic headline about your company history, there’s a mismatch — and the visitor’s instinct is to go back and try a competitor who speaks more directly to their need.
Every significant keyword theme should have a dedicated landing page that echoes the specific promise of the ad. If you’re bidding on “Google Ads management for law firms”, the landing page should be specifically about Google Ads for law firms — not a generic PPC services page.
“We run an audit of every new client account. The most common finding, by a long way, is homepage traffic. Sending Google Ads clicks to a homepage is almost always a mistake. Build the right landing page and CPA drops immediately.”
— Jay D, Performance Marketing Specialist, Synap GrowthAd copy that doesn't convert
Most Google Ads copy is written to be inoffensive rather than compelling. It describes the product or service without differentiating it. It uses generic CTAs like “Learn More” instead of specific, benefit-led calls to action. And it fails to address the buyer’s specific anxieties or objections.
- Lead with the benefit, not the feature — Not “SEO services in London”, but “Rank #1 for the keywords that drive revenue”
- Use numbers where possible — “98% client retention” is more compelling than “trusted by businesses”
- Address the objection — “No lock-in contracts” removes a common reason not to engage
- Match the search intent precisely — Emergency queries need urgent language; research queries need educational copy
Conversion tracking errors
You cannot optimise an account without accurate conversion data. Yet a significant proportion of UK Google Ads accounts have tracking errors — duplicate conversions counting the same lead multiple times, missing conversions from broken tag implementations, or incorrectly configured conversion windows.
The specific fix depends on your setup, but the starting point is always the same: go to Tools > Conversions and audit every active conversion action. For each one, check the status (should be “Recording conversions”), the attribution model, the conversion window, and whether it’s set as a primary or secondary conversion action. If you’re seeing conversion counts that seem too high or too low relative to what your CRM or backend shows, you almost certainly have a tracking problem.
Wrong bidding strategy
Google’s automated bidding strategies (Target CPA, Target ROAS, Maximise Conversions) are powerful — but they require sufficient data to function correctly. A campaign generating fewer than 30–50 conversions per month doesn’t have enough data for Google’s algorithm to make reliable bidding decisions. Running Target CPA on a low-conversion-volume campaign typically results in either very restricted delivery or wildly inconsistent CPAs.
For new campaigns or campaigns with low conversion volume, Manual CPC or Maximise Clicks (with a CPC cap) is often more effective while you build data. Once you’re consistently generating 50+ monthly conversions, transition to a smart bidding strategy and give it 4–6 weeks to fully optimise before evaluating performance.
Diagnosing why the clicks don’t convert
When Google Ads drives clicks but not customers, the cause is almost always one of four things: you are buying the wrong searches, your tracking is wrong so you are optimising blind, your landing page does not match the promise of the ad, or your offer is not competitive. Work through them in that order. Most accounts we audit are leaking budget on broad, low-intent terms and sending the traffic to a generic homepage.
Landing pages do the converting
The ad earns the click; the landing page earns the customer. A high-converting page continues the exact message of the ad, loads fast, makes the next step obvious, and removes every unnecessary field and distraction. Fixing the page often lifts return more than any bid change — which is why our web team and PPC team work together rather than in silos.
A 30-minute Google Ads conversion audit
- Conversions: confirm each conversion action fires once, records the right value and reflects a real lead or sale.
- Search terms: review the last 30 days and add negatives for anything irrelevant.
- Locations: check “presence” targeting so ads only show to people in your service area.
- Landing pages: make sure each ad group sends traffic to a page that matches the search, loads quickly on mobile and has one clear call to action.
- Bidding: ensure smart bidding targets are realistic and based on enough conversion data.
- Ad schedule and devices: look for hours or devices that spend without converting.
Most accounts we audit have at least three of these issues. Fixing them often improves conversion rate before any new campaign is built. See our PPC management service for help.
Fix tracking, then optimise to revenue
You cannot improve what you cannot measure accurately. We rebuild conversion tracking first — deduplicated, tied to real leads and sales — then let smart bidding optimise toward revenue rather than vanity conversions. Paired with disciplined negatives and expert Google Ads management, that is how an account that was burning budget starts compounding returns.
Frequently asked questions
Why am I getting clicks but no conversions on Google Ads?
The most common causes are irrelevant search terms, landing pages that don’t match the ad, broken conversion tracking and targeting outside your service area.
How do I check if my Google Ads conversion tracking works?
Use Google Tag Assistant and the conversions report to confirm each action fires once and records correctly, then test a real enquiry yourself.
What is a good Google Ads conversion rate in the UK?
It varies by sector and offer. Compare against your own history and focus on cost per qualified lead or revenue rather than an industry average.
Should I use broad match keywords?
Broad match can work with smart bidding and strong conversion data, but it needs close search term monitoring and good negative keyword lists.
How long does it take to fix an underperforming account?
Obvious waste can be removed in days, while performance typically stabilises within four to eight weeks of restructuring.
