Google Ads can be one of the fastest ways for a small business to get in front of ready-to-buy customers. It can also be one of the fastest ways to spend a few thousand dollars and have nothing to show for it. The difference between those two outcomes is rarely the budget, the industry or the competition. It is usually a handful of avoidable mistakes.
The tricky part is that a badly set-up account does not look broken. The dashboard fills with impressions and clicks, the spend goes out on schedule, and everything appears to be happening. Meanwhile the phone is not ringing any more than it was, and the owner is left wondering whether Google Ads simply does not work for a business like theirs.
It usually does. It just needs to be pointed at the right people, sending them to the right page, with someone actually watching. Here are the Google Ads mistakes small businesses make most often, in roughly the order they cost you money, and the practical fix for each.
1. Running ads without conversion tracking
This is the big one, and it sits underneath almost every other problem on this list.
Conversion tracking is simply telling Google what counts as a win: a phone call, a completed enquiry form, a booking. Without it, your reporting shows clicks and impressions, and nothing about whether any of those clicks turned into a customer. You cannot tell which keywords earn their keep and which quietly drain the budget, because every click looks identical.
Worse, Google’s automated bidding needs conversion data to work. Without it, the system is optimising towards clicks, and it will get you plenty, from people who were never going to call.
The fix. Set up conversion tracking before you spend another dollar. Track form submissions and phone calls at minimum. Once it is running, you can finally answer the only question that matters: what does a lead cost me, and is that less than a customer is worth?
2. No negative keywords
Google will happily show your ads for searches that are related to your keywords but useless to you. A plumber bidding on “drain repairs” can end up paying for “how to fix a drain yourself”, “drain repair jobs”, “plumbing apprenticeship” and “free plumbing advice”.
Every one of those clicks costs the same as a real customer’s click. In a small account, this kind of waste routinely eats a third of the budget or more.
The fix. Read your search terms report, the list of what people actually typed before clicking. Add anything irrelevant as a negative keyword. Build a standing negative list covering the usual suspects: free, cheap, DIY, how to, jobs, salary, courses, second hand, plus any services you do not offer. Then keep reviewing it fortnightly, because new junk searches always appear.
3. Broad match with no supervision
Broad match lets Google show your ad for anything it considers related to your keyword. On a large budget with good conversion data, that flexibility can find opportunities you would not have thought of. On a small budget with no tracking, it is an open tab at the bar.
The fix. If your budget is modest, start with phrase and exact match, where you keep control of which searches trigger your ads. Expand into broader matching later, once conversion tracking is feeding the system real data and you have negatives in place to fence it in.
4. Sending every click to your homepage
This one is extremely common and quietly expensive. Someone searches “ducted heating repair Frankston”, clicks your ad, and lands on a homepage that talks about everything your business does. Now they have to find their way to the relevant information themselves. Many will not. They will hit back and click your competitor instead.
You paid for that click either way.
The fix. Send each ad group to the page that matches the search, almost always the specific service page. It lifts conversion rates immediately, and because the page matches the ad and the search, it usually improves your Quality Score too, which lowers what you pay per click. If your site does not have proper individual service pages yet, our guide to writing service pages that rank and convert is the place to start, because it fixes your paid and organic performance at once.
5. Slow or awkward landing pages
Even the right page fails if it takes six seconds to load or is fiddly on a phone. A large share of ad clicks come from mobile, often from people who need something dealt with now. If your page is slow, or the phone number is not tappable, or the form asks for nine fields, you lose people you have already paid for.
The fix. Make sure the page you are sending paid traffic to is genuinely fast on mobile, with an obvious phone number and a short form. Fixing the page is often cheaper than increasing the budget and produces a bigger lift.
6. Wrong location and schedule settings
Two settings quietly waste money in a surprising number of small accounts.
Location. By default your ads can reach a far wider area than you service, sometimes the whole country. Worse, the default targeting setting includes people who show interest in your area, not just people in it. A Melbourne electrician can end up paying for clicks from interstate.
Schedule. If nobody answers the phone at 11pm and your business relies on calls, running ads around the clock spends money at hours that rarely convert.
The fix. Set your location targeting to the areas you genuinely service, and choose the option that targets people in those locations rather than merely interested in them. Then look at when your enquiries actually come in and weight your schedule towards those hours.
7. Ads that do not match the search
Generic ad copy (“Quality Service, Competitive Prices, Call Today”) is invisible. It says nothing, matches nothing specific, and gives no reason to choose you over the three ads above yours.
The fix. Mirror the searcher’s language. If the search is “emergency electrician Brighton”, the ad should say emergency electrician and Brighton. Include the thing that actually differentiates you: same-day service, fixed pricing, 20 years local, licensed and insured. Specific beats clever. And make sure the ad matches the page it leads to, so the visitor’s expectation is met on arrival.
8. Ignoring ad assets and extensions
Assets (the extra lines beneath your ad like call buttons, location, sitelinks and callouts) are free to add. They make your ad physically bigger on the page, give people more ways to act, and typically lift click-through rates. Plenty of small accounts skip them entirely.
The fix. Add call assets (particularly valuable for trades and services, where a tap-to-call is the whole point), location assets, sitelinks to your main service pages, and callouts for your key selling points. It takes half an hour once. Google Ads walks you through each type, and the Google Ads Help centre covers the setup in detail.
9. Set and forget
Google Ads is not a slow cooker. Search behaviour shifts, competitors change their bids, new irrelevant search terms appear, and campaigns drift. An account left alone for three months is almost always spending worse than it was on day one.
Related: letting Google’s “recommendations” auto-apply. Some are useful; others will broaden your targeting or raise your budget in ways that suit Google more than you.
The fix. Put a recurring half hour in the diary each week or fortnight. Check the search terms report, add negatives, pause keywords that spend without converting, and shift budget towards what does convert. Turn off auto-apply for recommendations and review them yourself.
10. Judging the wrong numbers
Owners often look at impressions, clicks or click-through rate, because those are the numbers presented most prominently. None of them pay wages.
There are really only three numbers that matter for a small business: how many leads did I get, what did each one cost, and what is a customer worth to me? If a lead costs $40 and your average job is $900, you should probably be spending more, whatever the click-through rate says. If a lead costs $400 on that same job, something needs fixing.
The fix. Report on cost per lead and, where you can, cost per customer. That is also the honest way to compare Google Ads against your other marketing, our post on SEO or Google Ads for Melbourne small businesses covers how the two work together rather than competing.
This is how we approach paid search for clients like Smarter Home Renovations and Worm Farm Waste Systems, where search advertising sits alongside local SEO, social and analytics so every dollar can be traced to a result rather than a click count.
11. Expecting too much from too little
A small budget spread across forty keywords in five campaigns produces nothing anywhere. Each keyword gets a fraction of a click a day, no campaign gathers enough data to optimise, and the whole account underperforms.
The fix. Narrow the focus. Pick your highest-value service and the searches most likely to convert, and put the whole budget behind those. Win there first, then expand. Our article on what a $1,000 Google Ads budget can actually do sets out realistic expectations for a modest spend.
A quick self-audit
Run through these. Every “no” is money you are probably leaving on the table:
- Is conversion tracking installed and recording calls and form submissions?
- Do you have a negative keyword list, and have you added to it this month?
- Are your ads sending clicks to specific service pages rather than the homepage?
- Is your location targeting limited to the areas you actually service?
- Does your ad copy repeat the words people are searching for?
- Have you added call, location and sitelink assets?
- Do you know your cost per lead?
- Has anyone properly reviewed the account in the last month?
Most struggling small business accounts fail four or more of these. The encouraging part is that none of them are hard to fix, and each fix compounds. Better targeting means better data, which means better bidding, which means a lower cost per lead.
Frequently Asked Questions
Why are my Google Ads not working?
The most common reasons are that you cannot actually tell whether they are working, or that your budget is being spent on the wrong searches. Without conversion tracking you only see clicks, not leads, so a campaign can look busy while producing nothing. Add tracking first, then look at negative keywords, match types and where your clicks are landing, those four things explain most underperforming accounts.
What is the biggest Google Ads mistake?
Running ads without conversion tracking. It sounds technical, but it is simply telling Google what counts as a win: a phone call, a form submission, a booking. Without it you cannot tell which keywords produce customers and which only produce clicks, so you cannot cut the waste or invest more in what works. Everything else is guesswork built on top of that gap.
Do I need negative keywords in Google Ads?
Yes, and most small accounts do not have nearly enough. Negative keywords stop your ads showing for searches you never want to pay for, such as “free”, “DIY”, “jobs”, “salary”, “cheap” or the name of a service you do not offer. Reviewing your search terms and adding negatives regularly is one of the quickest ways to stop wasting budget.
Should Google Ads go to my homepage?
Almost never. The homepage is a general introduction to your business, so someone who searched for one specific service has to find their way from there, and many will not bother. Send each ad group to the page that matches the search, usually the relevant service page. It lifts conversions and usually improves your Quality Score, which lowers your cost per click.
How often should I check my Google Ads?
For a small account, a proper review every week or fortnight is a reasonable rhythm. Check the search terms report, add negatives, pause what is not converting and adjust budgets. Set-and-forget is where money leaks away quietly. What matters is regular, deliberate attention rather than logging in daily to change things at random.
The bottom line
Google Ads rarely fails because the platform does not work. It fails because nobody told it what a win looks like, nobody stopped it paying for the wrong searches, and the clicks it did earn landed on a page that was not built to convert them.
Fix those three things (conversion tracking, negative keywords and proper landing pages) and most struggling accounts turn around without spending an extra cent. Add regular attention and honest reporting on cost per lead, and paid search becomes what it should be: a tap you can turn up when you want more work, with a known cost and a known return.
