Plenty of small businesses run Google Ads themselves, and for a while it feels fine. The campaign is live, the budget is spending, clicks are coming in. Then the monthly invoice arrives and the obvious question lands: what did all of that actually buy?
That question is harder to answer than most owners expect. In its 2025 study of more than 250,000 Google Ads reports covering over 15,000 accounts, WordStream found that the average business wastes roughly a third of its monthly search budget, about $1,127 of an average $3,127 spend (Source: WordStream, 2026). The money is not disappearing because Google Ads does not work. It is disappearing because accounts drift, and nobody is watching them closely enough to catch it.
The good news is that wasted spend leaves fingerprints. Here are five signs your account has crossed from “running” into “leaking,” along with how to spot each one and what changes when someone manages it properly.
1. You cannot say how many leads or sales the ads produced
This is the first thing to check, because if it is broken, every other number you look at is fiction. Conversion tracking is the piece of code that tells Google Ads when a click turned into a phone call, a form submission, or a purchase. Without it, you are flying blind.
It is more common than you would think. In the same WordStream study, about 29% of accounts recorded zero conversions over a 90-day period, and one of the leading reasons is that conversion tracking was never set up correctly in the first place (Source: WordStream, 2026). Those campaigns may well have driven real business, but the account had no way to know which clicks were worth anything.
How to spot it: Open your account, find the “Conversions” column, and ask whether the numbers there match real leads in your inbox or calls to your phone. If the column is empty, or the figures look nothing like reality, tracking is broken.
What good management changes: A manager wires tracking to the actions that actually matter to you (a booked call, a quote request, a sale) and verifies it fires correctly before spending another dollar. From then on, every decision is based on results rather than guesswork.
2. Your keywords are matching searches that have nothing to do with you
Google offers different keyword “match types,” and the loosest of them, broad match, lets Google show your ad for searches it merely thinks are related. Left unchecked, a plumber can end up paying for clicks on “plumbing apprentice jobs” or “how to fix a tap yourself.” Every one of those clicks is billed at full price and will never become a customer.
How to spot it: Look at the “Search terms” report, which shows the actual queries people typed before clicking. Read through a week of them. If a meaningful share are irrelevant to what you sell, you are funding traffic that cannot convert.
What good management changes: A manager tightens match types where it makes sense and reviews search terms regularly, turning the bad ones into negative keywords (more on those next) so the same waste does not repeat.
3. You have never added a negative keyword
Negative keywords are the searches you tell Google to ignore. They are the single cheapest lever in the entire account, and they are routinely left untouched. WordStream found that 25% of businesses had not added a single one (Source: WordStream, 2026).
The impact is not small. In the same dataset, accounts with at least one negative keyword averaged a 13% conversion rate, while accounts with none averaged just 4.6% (Source: WordStream, 2026). That gap is roughly the difference between a campaign that pays for itself and one that quietly drains the budget.
How to spot it: Check your negative keyword list. If it is empty or has only a handful of entries, this is almost certainly costing you.
What good management changes: A manager builds and maintains a negative keyword list from real search data, filtering out job seekers, DIY researchers, free-stuff hunters, and competitor brand names so your budget concentrates on people ready to buy.
4. The results have gone flat and nobody knows why
Many accounts hit a plateau. Spend holds steady, clicks hold steady, but leads stop growing, or quietly slide. The instinct is to raise the budget, which usually just buys more of the same mediocre traffic.
A plateau is rarely one big problem. It is usually a stack of small ones: ad copy that has gone stale, a landing page that loads slowly or asks for too much, bids that no longer fit the competition, or a single ad group quietly eating budget while the profitable ones starve.
How to spot it: Pull the last six months of conversions and cost side by side. If cost is steady or climbing while conversions are flat or falling, you have a plateau, not a healthy plateau.
What good management changes: A manager treats the account as something to test and improve, not maintain. Trying new ad copy, reworking landing pages, and reallocating budget toward what converts is ongoing work, and it is the difference between a flat account and one that compounds. This is the bulk of what a hands-on partner like DGR TechLabs does week to week.
5. You set it up once and have not logged in since
This is the symptom underneath the other four. Google’s own guidance is clear that search campaigns are not a “set it and forget it” channel; auctions, competitors, and search behavior shift constantly, and accounts need regular attention to keep pace (Source: Google Ads Help, 2025). An account left alone does not hold steady. It decays.
How to spot it: Check the last time you genuinely reviewed the account, not glanced at the dashboard, but read the search terms, adjusted a bid, or paused something. If you cannot remember, the account has been running on autopilot.
What good management changes: Consistency. Routine reviews catch the broad-match drift, the missing negatives, and the early plateau before they compound into a season of wasted spend.
The self-check
Score yourself one point for each sign that applies:
- Cannot confirm leads or sales from the ads
- Search terms include plenty of irrelevant queries
- Few or no negative keywords
- Results flat or sliding for months
- No real account review in the last 30 days
Zero or one, you are probably fine to keep going. Two or three, there is money on the table worth recovering. Four or five, the account is most likely losing more than it would cost to have someone manage it properly, and bringing in help usually pays for itself out of the waste it eliminates.
