How to stop Google Ads wasting your budget

Most of the Google Ads accounts I look at are not broken. They are leaking. The campaigns are running, the clicks are coming in, the monthly spend goes out on time, and a quiet slice of it is paying for searches the business would never have chosen to appear for.

That is the frustrating thing about wasting your Google Ads budget. It rarely looks like a problem from the outside. The dashboard is green, the money is clearly being spent, and the graphs tick along. You only notice when you stop and ask a simple question: what were people actually searching for when they clicked my advert? Nine times out of ten, that question is where the money is hiding.

The report that shows where the money actually goes

There is one screen in Google Ads that tells you more about where your budget is going than any other, and most business owners have never opened it. It is the search terms report. In the account it sits under the keyword section, and it lists the real phrases people typed before they clicked your advert, as opposed to the keywords you told Google you wanted.

Those two things are not the same, and the gap between them is where a lot of money goes.

I once looked at an account for a commercial plumber who was happily paying for clicks on "plumber salary", "plumbing apprenticeship" and "how to fix a radiator yourself". None of those people were ever going to ring and book a job. They were job hunters and DIYers, and the account had been quietly paying for them for the better part of a year. The owner had no idea, because nothing on the main screen said so. You only see it when you read what people actually searched.

Before you change a single thing, spend ten minutes in that report. Set the date range to the last few months and read down the list. You are looking for anything with the word "free", anything to do with jobs, courses or salaries, anything aimed at people doing it themselves, and anything about a town or a service you do not cover. It can be uncomfortable reading, but it is the most useful ten minutes you will spend on the account.

Keywords are what you bid on, search terms are what you get

To understand why the leak happens, it helps to know how Google matches your adverts to searches. When you add a keyword, you also choose how loosely Google is allowed to interpret it, and the default setting, broad match, is very loose indeed.

Tell Google you want to appear for "emergency electrician" on broad match and it will cheerfully show your advert for "electrician courses", "electrician near me reviews", or a vaguely related phrase it has decided is close enough. Google leans towards broad match because, from its side, more matched searches means more clicks and more spend. That is not a conspiracy, it is simply that its interests and yours are not identical, and the default settings reflect its interests.

This is also why a high optimisation score or a pile of Google's own recommendations can sit next to an account that is bleeding money. The platform is optimising for its own definition of activity, not for your enquiries.

None of this means broad match is always wrong. In a well-set-up account with good conversion tracking and a healthy list of negatives, it can find searches you would never have thought to add yourself. But handing it a loose match type and then never checking what it brings in is how most waste starts.

Negative keywords: the cheapest change you can make

Once you have read the search terms report, the fix is straightforward. A negative keyword is simply a word or phrase you tell Google you never want to appear for. Add "free" as a negative and your advert stops showing to anyone whose search contains that word. Add "jobs", "salary", "course" and "training" and the job hunters disappear from your bill.

This is the single cheapest improvement you can make to a Google Ads account. It costs nothing, it takes a few minutes, and it goes straight to the bottom line, because every search you block is a click you no longer pay for. The budget that was being spent on the wrong people is now free to spend on the right ones.

A few negatives worth considering for almost any local service business:

• Words that signal no intention to buy: free, cheap, DIY, how to, yourself
• Words that signal someone wants a job, not a quote: jobs, salary, career, vacancies, apprenticeship
• The names of towns or areas you do not actually serve or want to travel to

Keep a running list as you go. Every month or two, something new will turn up in the search terms, and over time your negative list becomes one of the most valuable things in the account.

A simple routine that keeps the leak closed

Cleaning the account out once is good. The waste creeping back is almost guaranteed if you leave it, because the searches people type change constantly and broad match keeps testing new ones. So the real answer is not a one-off tidy but a short, regular habit.

Once a month, open the search terms report, read down the new entries, and add negatives for anything that is clearly not a customer. That is genuinely it. Ten to fifteen minutes a month will keep the biggest leak in most accounts firmly shut. It is far less glamorous than tweaking bids or rewriting adverts, and it does more good than either.

If you would rather not do it yourself, this is exactly the kind of thing a decent account manager should be doing without being asked. It is also the first thing worth checking if you are an agency weighing up whether to white-label your clients' Google Ads rather than running them in-house, because a partner who is not reading the search terms is not really managing the account.

When the waste isn't in the search terms

Sometimes the budget is being spent on the right searches and the money still is not turning into work. If the search terms look sensible but the enquiries are not coming, the problem has usually moved further down the line, to the page people land on or to the tracking itself.

It is worth being sure your conversion tracking is counting the right thing before you trust any of the numbers, and worth reading why good clicks so often fail to turn into enquiries once the landing page is involved. But start with the search terms. In my experience that is where the most obvious, most expensive, and most easily fixed waste nearly always sits.

If you want a second pair of eyes on it, send us the account and we will read the search terms for you and tell you plainly where the budget is going. It is free, there is no obligation, and more often than not it pays for itself in the first month.
