7 places local businesses waste money in Google Ads (and how to check each in five minutes)
Most wasted ad spend hides in the same seven places. Here's where to look in your own account, what "bad" looks like, and what to do about it.
When we look at a new Google Ads account for a local service business, the waste is rarely exotic. It sits in the same handful of places, month after month, because nobody has time to check them. None of these checks needs special tools. Each takes about five minutes in Google Ads.
1. Conversions that aren't leads
Open Goals → Conversions and look at what's marked as a primary conversion. Bidding and every report follow those. If a page view, a click on a button, or a call of a few seconds counts as a conversion, Google is optimising for the wrong thing, and every cost-per-lead number you see is too low.
What to do: keep only real leads as primary conversions (form submissions, calls of a meaningful length, booked appointments). Set everything else to secondary. For calls from ads, check the minimum call length; 60 seconds is a sensible starting point for most service businesses.
2. Searches that will never buy
Open the search terms report for the last 30 or 90 days and sort by cost. Look for job seekers ("technician jobs", "salary"), do-it-yourselfers ("how to", "diy", "parts"), freebie hunters ("free") and the wrong service entirely.
What to do: add the clearly irrelevant words as negative keywords. Be careful with single words: blocking "cost" also blocks "AC installation cost", which is often a great lead. When in doubt, block the exact search rather than the word.
3. Ad groups and keywords that spend without converting
Sort ad groups by cost and look at the ones with no conversions. The question isn't "has it converted?" but "should it have by now?" An ad group that took 20 clicks with no lead may just be unlucky. One that took 200 clicks, when the rest of the campaign converts 5% of clicks, was due about 10 leads. Zero is very unlikely to be bad luck.
What to do: pause the clear losers. For the borderline ones, wait for more clicks rather than guessing. We wrote more about this in when to pause a keyword.
4. Hours and days that never convert
Look at results by hour of day. Many service businesses pay for clicks at 2 a.m. that never turn into calls, because nobody answers the phone and the people searching are researching, not buying.
What to do: if a block of hours has had plenty of clicks and no leads, add an ad schedule that excludes it, or lower bids there. Check the whole night as one block (10 p.m. to 6 a.m., say), not as two halves either side of midnight.
5. Places you don't serve
Check the location report, and in campaign settings check the location option. "Presence or interest" shows ads to people who are merely interested in your area, which for a plumber or roofer usually means clicks from people who can't become customers.
What to do: for a local service business, target people in your area. Exclude towns that keep spending without leads, but only once they've had enough clicks to judge.
6. Devices with no leads
Look at results by device. Tablets in particular often take a small but steady share of spend and rarely produce calls.
What to do: if one device has spent real money with no conversions while others convert, lower its bid adjustment or switch it off. On smart bidding, Google adjusts by device itself, so only switch off a device that clearly never converts.
7. Ads nobody sees
Finally, check for ad groups where every ad is disapproved, or ads that still promise last season's offer. They don't waste money directly, but they waste the keywords behind them.
What to do: fix or replace disapproved ads, and remove dated offers ("ends September 30") as soon as they pass.
A habit, not a project
None of these is a one-off fix. Searches change, tracking breaks when the website changes, and new campaigns bring new waste. The accounts that stay healthy are the ones where somebody runs these checks every week.
That's what PPC Master does: it runs these checks on every sync, puts a dollar figure on each problem, says how sure it is, and lines up the fix for you to approve. The free audit shows what it finds in your account.
