Google Ads can be one of the fastest ways to grow a business — or one of the fastest ways to burn cash. The difference usually isn’t your industry or your budget. It’s a handful of fixable mistakes quietly draining the account. Here are the big ones and what to do about them.
You’re paying for the wrong searches
The most common leak is showing your ads to people who were never going to buy. If you sell premium accounting services and your ad appears for “free accounting software” or “accounting jobs,” you’re paying for clicks that can’t convert.
The fix is negative keywords — a list of terms you tell Google to exclude. Most underperforming accounts have a tiny negative list, or none at all. Spend twenty minutes in your search terms report (which shows the actual phrases people typed before clicking) and you’ll usually find obvious waste to cut. Do this regularly, not once.
While you’re there, reconsider your match types. Broad match casts a wide net and, left unchecked, catches a lot of junk. Tighter match types keep you closer to the searches that actually matter.
Your ads send people to the wrong page
Plenty of advertisers point every ad at their homepage. That’s a money loser. If someone searches for a specific service, they should land on a page about that exact service — not a general homepage where they have to hunt for what they wanted.
The page you send clicks to is your landing page, and it matters as much as the ad. A focused page with a clear headline, the offer, the proof, and one obvious next step will convert far better. Sending paid traffic to a vague or slow page is like paying for a taxi that drops people a mile from the door. If your site lets you down here, our website and marketing help is built for exactly this.
You’re not tracking what actually matters
If you can’t see which clicks turn into leads or sales, you’re flying blind — and you’ll keep funding campaigns that look busy but produce nothing.
Set up conversion tracking so Google knows what a “win” looks like: a form submission, a call, a purchase. Without it, the algorithm optimises for clicks instead of customers, and you optimise for the wrong things too. Once tracking is in place, you can finally see which campaigns, keywords and ads earn their keep — and pour budget into those while cutting the rest.
Your structure is a mess
Many accounts lump unrelated keywords into one campaign with a single generic ad. That forces you to show the same message to people searching for very different things, which drags down relevance and pushes up your costs.
Group tightly related keywords together and write ads that speak directly to each group. The closer the match between the search, the ad and the landing page, the more Google rewards you — usually with a better Quality Score, lower cost per click, and stronger positions. Tighter structure is one of the highest-return changes you can make.
You set it and forgot it
Google Ads is not a slow cooker. Costs shift, competitors change their bids, and search behaviour moves. An account left alone for months almost always drifts toward waste.
You don’t need to live inside the dashboard, but a regular check-in pays for itself: prune wasteful search terms, pause weak ads, lean into what’s converting, and test fresh ad copy. Small, consistent adjustments compound into meaningfully lower costs and more leads.
The bottom line
Most “Google Ads doesn’t work for us” stories are really “our account was never set up to work.” Cut the wasted clicks, match ads to dedicated landing pages, track real conversions, tighten your structure, and tend the account — and the same budget can go from a leak to a reliable source of customers.
