Broad Match and Missing Negative Keywords
Broad match keywords let Google show your ads for a wide range of related searches—including many that have nothing to do with what you sell. Without tight controls, you can pay for clicks from people searching for free options, jobs, or unrelated products. The intent simply isn't there.
Negative keywords are the fix. By telling Google which terms you don't want to appear for, you stop paying for irrelevant clicks. A neglected negative keyword list is one of the most common and costly oversights in an account, and it needs ongoing attention as new irrelevant searches surface.
Bidding on the Wrong Searches and Sending Clicks Nowhere
Bidding on overly broad terms attracts clicks from people who aren't ready to buy. A search like "marketing" is vague; a search like "marketing agency for dental practices" signals real intent. Spending on the vague end of that spectrum burns budget on browsers, not buyers.
Even a perfect click is wasted if it lands on a weak page. Sending paid traffic to a generic homepage, a slow page, or one that doesn't match the ad's promise leaks money. Every click you pay for should arrive somewhere relevant, fast, and built to convert.
Ignoring Devices, Locations, and Schedules
Not all clicks are equal. Some devices, locations, or times of day convert far worse than others, yet many accounts spend evenly across all of them. If you serve a specific area, paying for clicks from outside it is pure waste—and it's easy to leave that setting too loose.
Reviewing performance by segment lets you shift budget toward what works and pull back where it doesn't. Showing ads at 3 a.m. when no one's answering, or in regions you can't serve, quietly drains spend that could go to your best-performing segments.
Letting Automation Run Unsupervised
Automated bidding and broad targeting can work well, but they optimize toward whatever goal you set—and if that goal is poorly defined, they'll efficiently spend toward the wrong outcome. Set-and-forget is where a lot of budget disappears.
The seventh leak is simply a lack of regular review. Search terms drift, competitors change, and what worked last quarter may not work now. Accounts that aren't actively managed accumulate waste. This is exactly the kind of ongoing oversight CMG provides when it runs paid search done-for-you—watching the levers so the budget keeps working.
Key takeaways
- Tighten match types and maintain an active negative keyword list to stop irrelevant clicks.
- Bid on intent-rich searches and send every paid click to a fast, relevant landing page.
- Adjust for devices, locations, and schedules instead of spending evenly across all of them.
- Don't let automation run unsupervised—define goals clearly and review the account regularly.
