The Default Settings Are Not on Your Side
When you create a Google Ads campaign, the default configuration is optimised for one thing: maximising Google’s revenue. Broad match keywords are enabled by default. The Search Partners network is opted in. Display expansion is switched on. Auto-applied recommendations — which Google euphemistically calls “optimisations” — are active from day one.
Each of these defaults widens the net. Your ad for “commercial solicitor Leeds” starts appearing for “free legal advice”, “what does a solicitor do”, and “solicitor salary UK”. Every one of those clicks costs you money. None of them are potential clients.
The first thing any competent campaign manager does is undo every one of those defaults. The fact that most agencies do not tells you everything about how they operate.
Negative Keywords Are Not Optional — They Are the Entire Strategy
A negative keyword list is the most valuable asset in any Google Ads account, and the one most consistently neglected. Without it, you are paying for traffic from people who have no intention of buying, no budget to spend, and no relevance to your business.
For a financial adviser running ads on “pension advice”, a missing negative keyword list means paying for clicks from people searching “state pension age”, “pension credit eligibility”, and “free pension calculator”. These are informational queries. The intent is research, not engagement. And at three to eight pounds per click in competitive financial services categories, a hundred wasted clicks a month is a quiet, invisible drain of several hundred pounds — every single month.
Building and maintaining a negative keyword list is not a one-time task. It requires weekly review of search term reports, pattern recognition across query clusters, and the discipline to keep pruning. This is the work most agencies skip because it does not scale, it is not glamorous, and the client will never see it unless they know to ask.
Your Landing Page Is Costing You More Than You Think
Google assigns a Quality Score to every keyword in your account. This score — a combination of expected click-through rate, ad relevance, and landing page experience — directly determines how much you pay per click and where your ad appears.
A keyword with a Quality Score of ten pays roughly 50% less per click than the same keyword with a score of five. That is not a marginal difference. For a business spending five thousand pounds a month, improving Quality Score from five to eight can save over a thousand pounds monthly — or double the number of clicks for the same spend.
The landing page component of Quality Score is where most businesses fail. Sending ad traffic to your homepage is almost always wrong. A homepage serves multiple audiences and multiple purposes. A landing page serves one audience with one message that matches the exact intent of the search query. The page must load in under three seconds, work flawlessly on mobile, and make the next action obvious. If any of those conditions are not met, you are paying for clicks that bounce.
Conversion Tracking: The Blind Spot That Invalidates Everything
Here is the question that separates a functional Google Ads operation from theatre: can you tell me, right now, which keyword generated your last paying client?
If the answer is no — and for most businesses it is — then every optimisation decision in your account is based on incomplete data. You are optimising for clicks, or at best for form submissions, with no visibility into which of those form submissions actually became revenue.
Proper conversion tracking means tagging every meaningful action — phone calls, form submissions, email clicks, live chat engagements — and feeding that data back into the campaign so the algorithm learns which audiences, keywords, and ad variations actually produce business. Without this feedback loop, Google’s machine learning has nothing useful to optimise against. It will happily spend your budget generating clicks from people who will never buy.
What Good Looks Like
A properly managed Google Ads campaign is not complicated. It is disciplined. It looks like this: exact and phrase match keywords only, with broad match used sparingly and monitored daily. A negative keyword list that grows every week. Dedicated landing pages for every ad group. Conversion tracking that follows the lead through to revenue. Weekly search term reviews. Monthly performance reports that show cost per acquisition, not vanity metrics like impressions and click-through rate.
The gap between this and what most businesses are actually running is enormous. And that gap is where your budget disappears.
The Bottom Line
Google Ads is one of the most powerful lead generation tools available to UK businesses. But power without management is waste. If you are spending money on ads without a negative keyword strategy, without dedicated landing pages, without proper conversion tracking, and without someone reviewing search terms weekly — you are not advertising. You are subsidising your competitors’ lower cost per click.
The platform works. The question is whether anyone is making it work for you.
