Google Ads can be the fastest way for a local service business to generate leads. But for every Michigan business running profitable campaigns, there are ten burning through their budget with nothing to show for it. After managing Google Ads for service businesses across Jackson, Lansing, and Ann Arbor, here are the five most common mistakes we see.
1. Targeting too broad of an area
If you're a roofer in Jackson, Michigan, there's no reason to show ads to people in Detroit or Grand Rapids. Yet many small businesses set their targeting to the entire state or a 100-mile radius by default. Every click from someone outside your service area is wasted budget. Set your location targeting to the specific cities and zip codes you actually serve, and use "Presence" targeting (not "Presence or interest") to ensure only people physically in those areas see your ads.
2. Ignoring negative keywords
Without negative keywords, your ad for "HVAC repair" will show up for "HVAC repair jobs," "how to repair HVAC yourself," and "HVAC repair certification." None of those people will hire you. Review your search terms report weekly and add irrelevant queries as negative keywords. Common exclusions for service businesses include "jobs," "salary," "DIY," "training," "free," and "near me" for cities outside your area.
3. Sending traffic to your homepage
When someone clicks an ad for "emergency plumbing Jackson MI," they should land on a page specifically about your emergency plumbing services in Jackson, not your homepage. A dedicated landing page that matches the search intent will convert at two to three times the rate of a generic homepage. Every dollar spent driving traffic to the wrong page is a dollar wasted.
4. Not tracking conversions
If you don't know which keywords and ads actually generate phone calls and form submissions, you're flying blind. Without conversion tracking and call tracking set up properly, Google's algorithms can't optimize for the right outcomes, and you can't make informed decisions about your budget. This is the first thing that should be set up before you spend a single dollar on ads.
5. Setting it and forgetting it
Google Ads is not a "launch it and leave it" platform. Campaigns need weekly attention: bid adjustments, ad copy testing, keyword refinements, and budget reallocation based on what's actually converting. The businesses that see the best ROI are actively managing their campaigns, not checking in once a quarter.
When to get professional help
If you're spending more than $1,000 per month on Google Ads and not seeing a clear return, the cost of professional Google Ads management will likely pay for itself in reduced waste and higher conversion rates. A Google Ads audit is a good place to start if you want to see exactly where your budget is going and where it's being wasted.
