Nobody sets a budget line called waste. It arrives quietly, a little at a time, from half a dozen places at once. Add it up at the end of the year and it can rival anything you chose to spend money on.
Marketers themselves estimate they waste around a quarter of their budgets. When Rakuten Marketing surveyed more than 1,000 marketers in 2018, the average estimate was 26%, lost to poor planning and the wrong channels. US respondents put it at 30% or more. The survey is old, but the people running the campaigns were talking about their own work, and an account nobody has audited can easily be worse.
On a two thousand dollar a month budget, a quarter is six thousand dollars a year, gone, for nothing. On ten thousand a month it is thirty thousand.
Most of it drains through seven leaks: branded clicks you would have got for free, broken tracking, campaigns bidding against each other, irrelevant search terms, landing pages that lose the click, tired creative, and ads shown to people who already bought. You can find and fix every one of them without a bigger budget.
Here is the audit. Set aside about two hours.
One. Branded search you already owned
Start here, because in my view it is the leak that gets talked about least.
Open your search campaigns and split performance into branded and non branded. Branded means anyone searching your business name or a close variant.
Those conversions look magnificent, with a low cost and a high conversion rate. Most of them come from people who were already looking for you and would have clicked the organic result sitting directly underneath.
Automated campaigns love this traffic because it makes them look good. Left alone, they can drift more and more budget toward it. That drift gets harder to see as platforms push advertisers into broader automated campaign types, which is why we flagged it in Google moving campaigns to AI Max.
You may still choose to buy some branded traffic, to defend against competitors bidding on your name or to control the message. Make it a decision rather than a default, and never let branded results inflate the numbers you use to judge everything else.
How to do it in practice:
- Build a list of your brand terms. Include common misspellings, plus your founder's name if people search it.
- Add them as negatives in your non branded campaigns so the two never mix.
- Run branded search in its own small campaign with its own budget cap.
- Report the two separately, every time. A strong brand week should never hide a weak prospecting week.
Two. Tracking that was broken before you noticed
A lot of "our ads stopped working" conversations end at a broken pixel.
Check three things. Are conversions being counted more than once, for example a form submission that also fires on the thank you page? Are you counting non events like phone number clicks or PDF downloads as if they were sales? And on Meta, is the Conversions API running alongside your pixel with a healthy event match quality score?
Bad signal misleads you, and it misdirects the algorithm too, which spends real money finding more of the wrong thing.
Every automated ad system is a mirror. Feed it a distorted picture of success and it will go out and buy you more distortion, faster and cheaper every month.
The quickest test is to hold the ad platform's count against your own records. Pull last month's conversions from the ad account, then count the enquiries in your inbox or the orders in your store. Say the platform shows 80 leads and your inbox shows 41: something is double counting. If the platform shows far fewer, something is not firing. Either way, you have been optimising on fiction. If match quality is the weak spot, the boring number quietly deciding your ad results walks through fixing it.
Three. Audience and campaign overlap
Older accounts accumulate campaigns like a shed accumulates paint tins. Six ad sets, four of them aimed at broadly overlapping people, all turning up to the same auction.
You end up competing against yourself.
Consolidate. The symptom to look for is lots of ad sets each spending $10 or $15 a day, none of them getting enough conversions to learn from. Pick your strongest one or two, move the budget into them, and pause the rest. It feels like losing control. What you get in return is an algorithm with enough data to do its job.
Four. The search terms nobody has read
Open the search terms report in Google Ads, which lists the real searches that triggered your ads. Sort by spend. Read the top fifty.
Expect to wince. You will likely find job hunters, people after DIY instructions, someone trying to reach a competitor's warranty department, and searches for a service you stopped offering in 2022.
Broad matching and automated targeting pull all of it in. Some of it is valuable and you would never have thought to target it. The rest is money set on fire in small denominations.
Build the negative list. Then put it in the diary for every fortnight, because it refills.
Start with the usual suspects: jobs, careers, salary, free, DIY, how to, course, training, and the names of competitors you do not want to bid on. Then add anything specific to your industry that showed up in the report. When you find a great term you had never thought of, add it as a keyword in its own right so you can bid on it deliberately.
Five. Traffic sent to a page that leaks
This waste never appears in the ad account, which is why it survives so long.
You can get the targeting, the creative and the bid right, then send the click to a homepage with nine navigation links, a slideshow and a form below the fold that asks for eleven fields.
Check three numbers per landing page: how long the page takes to become usable on a phone on a normal connection, what percentage of visitors start the form, and what percentage finish it.
If a form loses 60% of the people who start it, no ad budget will outspend that.
The fixes are rarely glamorous. Send each campaign to a page that matches the ad's promise, word for word where you can. Strip out the navigation. Put the form or the call button where a thumb can reach it without scrolling. Cut every field you do not need to make first contact. Put reviews and your guarantee next to the button. If you want the full blueprint, see the anatomy of a landing page that prints money.
Six. Creative that finished working weeks ago
Winning ads tire. If your best performing ad launched in June and it is now September, there is a fair chance you are paying a premium to show it to people who have already made up their minds.
Check the launch date on every ad currently taking real budget. Anything older than a month with rising frequency and falling click through rate is costing you.
Don't panic and rebuild everything every fortnight. Keep a pipeline instead. Have new hooks and new angles in production before the current winners fade, so a replacement is ready the week performance dips. We covered the mechanics in your winning ad now dies in 14 days.
Seven. Retargeting people who already bought
This one is small and a bit embarrassing. Exclude converters from prospecting and from most retargeting. Otherwise you are paying to advertise a product to the people who already own it, which wastes money and mildly insults a new customer.
The fix is to upload or sync your customer list and build an audience of recent purchasers, then exclude it wherever you are trying to win new business. Keep a separate, deliberate campaign for existing customers if you have something new to offer them, such as a refill, an upgrade or a complementary product. That is marketing. Showing them the ad for the thing they bought last week is just a bill.
The two hour version
If you only have one sitting, do it in this order.
- Split branded from non branded search and judge them separately.
- Verify conversion tracking. Remove duplicates and non events.
- Read the top fifty search terms by spend and build negatives.
- Check launch dates on every ad taking meaningful budget.
- Load your main landing page on a phone and try to submit the form yourself.
- Confirm converters are excluded from prospecting.
None of this waste needs incompetence to get there. It accumulates in every account nobody audits.
Write down what you find as a dollar figure. "Branded search took a third of the budget" is easy to ignore. "We spent $4,200 last quarter on people who were already typing our name" gets acted on.
A worked example: the physio clinic audit
Say you run a physio clinic in Hobart spending $3,000 a month across Google and Meta, and your ad agency reports a healthy return every month.
You sit down for two hours. The branded split shows a big share of your Google conversions come from people searching your clinic's name. The search terms report is full of people looking for physio jobs and free exercise sheets. Your Meta pixel is firing a lead on both the form submit and the thank you page, so every enquiry is counted twice. Your best ad has been running since autumn. And your booking link sends people to a homepage with a slideshow and a long form.
Finding all that took no new strategy. Fix the tracking, cap branded spend and add negatives. Refresh the creative and point the ads at a proper booking page. Now the same $3,000 is doing more work. How much more depends on your account, which is why you audit it and do not guess.
Then do the harder thing
Once the waste is out, resist the urge to bank it. Move it into the two things that compound: more distinct creative, and a better offer.
Recovered waste spent on the same weak proposition buys you more of the same result, slightly cheaper. Spend it on something worth advertising and the year looks different.
Make the audit a habit, too. Search terms every fortnight, creative dates monthly, tracking and structure every quarter. Waste comes back the moment you stop looking. If you would rather have someone else do the looking, our advertising team runs this exact audit on Google and Meta accounts, then rebuilds the parts that leak. Either way, open the account this week. The money is already going somewhere.
Frequently asked questions
How much ad spend is typically wasted?
In a 2018 Rakuten Marketing survey of more than 1,000 marketers, respondents estimated they waste an average of 26% of their budgets, and accounts that have never been audited can be worse. The waste rarely comes from one big mistake. It builds up from branded clicks you would have got anyway, broken tracking, irrelevant search terms, overlapping campaigns, weak landing pages, tired creative and ads shown to existing customers.
Should I stop bidding on my own brand name?
Not necessarily. Bidding on your brand can protect you when competitors bid on your name and lets you control the message. The problem is letting branded results mix with everything else, which makes your campaigns look far better than they are. Run branded search separately with its own budget cap and judge it on its own numbers.
How often should I audit my Google and Meta ad accounts?
Review search terms every fortnight, since irrelevant queries keep appearing. Check creative performance and launch dates monthly, because ads tire. Do a full audit of tracking, campaign structure, exclusions and landing pages at least once a quarter, and any time results suddenly change.
How do I know if my conversion tracking is broken?
Compare the conversions your ad platform reports with what really happened, such as enquiries in your inbox or orders in your store, for the same period. Big gaps in either direction point to a problem. Also check whether one action fires multiple conversion events, and whether small actions like button clicks are being counted as if they were sales.
