Ad spend disappearing without clear results is one of the most common complaints we hear from businesses running their own PPC campaigns — or working with an agency that isn’t showing its workings. The budget is being spent. Clicks are happening. But leads, sales, or bookings aren’t following at a rate that makes sense.
Usually, the money isn’t vanishing into nothing. It’s going somewhere specific — it’s just not being tracked or optimised well enough to see where.
Here’s where it typically leaks.
1. Broad Match Keywords Catching the Wrong Searches
Broad match is the easiest way to spend a budget fast and the easiest way to spend it on searches that were never going to convert. A campaign targeting “kitchen renovation” on broad match can end up paying for clicks on “kitchen renovation shows on TV” or “how to renovate a kitchen yourself.”
Fix: Check your search terms report weekly, not monthly. Add irrelevant terms as negative keywords immediately, and shift genuinely relevant broad terms to phrase or exact match once you’ve confirmed they convert.
2. Landing Pages That Don’t Match the Ad
If someone clicks an ad for “same-day boiler repair” and lands on a generic homepage, most of them leave within seconds — and you’ve paid for that click regardless. A mismatch between ad promise and landing page reality is one of the most expensive, least visible leaks in a PPC account.
Fix: Build a dedicated landing page for each core campaign that mirrors the ad’s exact offer, with one clear call to action — not a general services page competing for attention with five others.
3. No Conversion Tracking, or Tracking the Wrong Thing
It’s common to find accounts tracking clicks and impressions closely while barely tracking what happens after — actual form fills, calls, or purchases. Without that, decisions about which keywords or ads to scale are effectively guesses.
Fix: Set up proper conversion tracking for the actions that matter to the business (form submissions, calls, checkout completions), not just clicks to the site. Everything else should be optimised against that number.
4. Campaigns Running on Autopilot for Months
Automated bidding strategies can work well, but left completely unmanaged, they tend to drift — spending more to chase volume rather than value, especially once a campaign has been live for a while without review.
Fix: Review bid strategy performance monthly at minimum. If cost-per-conversion is climbing while conversion volume stays flat, that’s usually a sign the algorithm needs a manual check-in, not more budget.
5. Competing Against Your Own Campaigns
Running multiple campaigns targeting overlapping keywords means you can end up bidding against yourself, driving up your own cost-per-click for no real benefit. This is easy to miss because each campaign looks fine in isolation.
Fix: Audit your account structure for keyword overlap across campaigns and consolidate where it makes sense, rather than letting campaigns compete in the same auction.
The Pattern Behind All Five
Every one of these leaks looks the same from the outside: spend goes up, results stay flat, and it’s not obvious why. The difference between an account that performs and one that doesn’t is usually not the size of the budget — it’s how closely each part of it is being watched.
