Most wasted Google Ads budget comes from a handful of fixable mistakes: no conversion tracking, broad keywords with no negatives, sending traffic to the homepage, and letting Google’s automation run without checks.
If your ads get clicks but not calls or sales, start here.
1. No conversion tracking
If Google cannot see which clicks become enquiries, it cannot optimise for them and you cannot judge results. Track calls, form submissions and purchases with GA4 and Google Tag Manager before spending another penny.
2. Using broad match with no negative keywords
Broad match can show your ads for loosely related searches like “free”, “jobs” or “DIY”. Build a negative keyword list from day one and check the search terms report every week.
3. Sending everyone to your homepage
Someone searching for “emergency roof repair” should land on an emergency roof repair page, with a phone number and a short form at the top. Matching the landing page to the search often lifts conversion rates sharply.
4. One campaign for everything
Mixing every service in one campaign hides what works. Split campaigns by service or goal so budget goes where it earns the most.
5. Ignoring location settings
By default, Google can show ads to people interested in your area, not just people in it. For local businesses, target “presence” in your service area.
6. Weak ad copy
Ads should include the service, the location, a clear benefit and a call to action. Use every relevant asset: sitelinks, callouts, call assets and location assets.
7. Bidding on your budget, not your goals
Smart bidding works well once you have conversion data. Without it, start with manual or maximise-clicks bidding with caps, then switch to target CPA when conversions are flowing.
8. Running ads at the wrong times
If nobody answers the phone at night, ads that drive calls at 2am waste money. Use ad schedules and adjust bids for your busiest hours.
9. Never testing
Test headlines, offers and landing pages regularly. Small improvements in click-through and conversion rates compound into much lower costs per lead.
10. Judging success by clicks
Clicks and impressions are not results. Measure cost per lead and cost per sale, and compare them with the value of a new customer.
How much should a small business spend on Google Ads?
Start with enough budget to get meaningful data, usually enough for several conversions a month, then scale what works. A smaller, focused campaign beats a large, unfocused one.
Should I use Google Ads or SEO?
Google Ads brings leads quickly; SEO builds free traffic over time. Most businesses get the best results using ads for immediate demand while SEO grows in the background. Read my comparison of Google Ads vs Meta Ads for the paid side.

- Fix tracking first; everything else depends on it.
- Control keywords, locations and schedules to stop wasted spend.
