Key Takeaways
- Google Ads will show your ads for searches that have nothing to do with your business unless you actively prevent it.
- The search terms report shows you exactly where your money went. Most business owners never look at it.
- Negative keywords are the most direct way to stop wasting budget on irrelevant traffic.
- Match type settings on your keywords control how loosely Google interprets what you are targeting.
- Checking your search terms report once a week takes less than ten minutes and can save you hundreds of dollars a month.
You are paying for clicks. The question is whether those clicks are coming from people who actually want to hire you.
Google Ads does not spend your budget only on the searches you intend to target. By default, it interprets your keywords broadly and matches your ads to searches it believes are related. Sometimes that works. Often it does not. A roofing contractor ends up paying for someone searching "roofing nails at Home Depot." A plumber pays for clicks from people looking for plumbing school programs. The money is gone either way.
This article explains why that happens, how to find where your budget is going, and what to do to stop the bleed.
Why Google Matches Your Ads to the Wrong Searches
When you add a keyword to a Google Ads campaign, you choose a match type. That match type tells Google how closely a user's search has to match your keyword before your ad can show.
Broad match, which Google defaults to and actively pushes, gives Google significant latitude. If your keyword is "water heater repair," broad match can show your ad for searches like "how to fix water heater yourself," "water heater cost," or "plumber license requirements." Google's algorithm decides those are related. Your budget does not know the difference.
Phrase match is tighter. It requires the meaning of your keyword to be present in the search. Exact match is the tightest, restricting your ad to searches that match your keyword very closely. Google's own documentation on keyword match types explains these in detail.
Most local service campaigns run on broad match because that is the default and because Google's setup flow steers you there. Broad match can work if you have a well-built negative keyword list. Without one, it will burn your budget.
How to Find Where Your Budget Is Actually Going
The search terms report shows you the actual searches that triggered your ads and resulted in clicks. This is different from your keyword list. Your keywords are what you told Google to target. The search terms report shows what Google actually matched.
To find it in Google Ads: click Campaigns in the left menu, then Keywords, then Search Terms. Set the date range to the last 30 days.
Look for patterns in what you see:
- Searches with no commercial intent ("how to," "DIY," "free," "what is")
- Searches in categories you do not serve ("wholesale," "parts," "certification")
- Brand names of competitors or suppliers
- Geographic searches outside your service area
- Searches related to your industry but not your service (a landscaper seeing "landscaping photography")
Sort the report by cost. The expensive irrelevant clicks are the ones that matter most right now. Start there.
How to Stop Paying for Searches You Do Not Want
Once you identify irrelevant searches, you have two tools: negative keywords and match type adjustments.
Negative keywords tell Google which searches should never trigger your ads. If you add "DIY" as a negative keyword, your ad will not show when someone searches "DIY water heater repair." Add negatives at the campaign level to protect your entire budget, or at the ad group level if only one service is affected.
Match type tightening reduces how broadly Google interprets your keywords in the first place. Switching from broad match to phrase match on your highest-spend keywords will reduce irrelevant traffic significantly. Exact match gives you the most control but also the smallest reach.
The table below shows how each match type behaves and when to use it for a local service business.
| Match Type | How It Works | Best Use Case |
|---|---|---|
| Broad Match | Google matches to anything it considers related | Avoid unless you have 100+ negative keywords in place |
| Phrase Match | Search must include the meaning of your keyword | Good starting point for most local service campaigns |
| Exact Match | Search must match your keyword very closely | High-value services where you know exactly how people search |
Most local campaigns do well with a mix of phrase and exact match, plus a strong negative keyword list built from the search terms report. You can learn more about building that foundation in what a local business should actually spend on Google Ads.
Building your negative keyword list is not a one-time task. You check the search terms report weekly, pull out new irrelevant searches, and add them as negatives. After the first month, the list stabilizes and weekly checks take very little time.
Google's shared negative keyword lists let you apply the same negatives across multiple campaigns at once, which saves time if you are running more than one.
Common negatives to add immediately for most local service businesses: "free," "DIY," "how to," "jobs," "career," "school," "training," "salary," "license," "certification," "wholesale," "parts."
If you are managing campaigns across multiple locations, the same principles apply but the volume of search terms to review is higher. The article on managing Google Ads for multi-location businesses covers how to structure that work without it taking over your week.
Frequently Asked Questions
How often should I check the search terms report?
Once a week is enough for most local service campaigns. If you are spending more than $2,000 a month on ads, check it twice a week for the first month until your negative keyword list is built out. After that, weekly reviews catch new problems before they compound.
Will tightening my match types hurt my reach?
Yes, and that is usually a good thing. Broad reach that produces irrelevant clicks is not helping you. A smaller audience of people who are actually searching for your service will convert at a higher rate and cost you less per real lead.
How many negative keywords should I have?
There is no target number. A well-maintained list for a local service business typically lands between 50 and 200 negatives after the first few months. What matters is that the list is built from your actual search terms data, not copied from a generic template.
Can I just let Google's Smart campaigns handle this automatically?
Smart campaigns give you less visibility into where your money goes, not more. You lose access to the search terms report and the ability to add negative keywords at the campaign level. For local service businesses where every dollar matters, that tradeoff is rarely worth it.
The single most important habit in managing Google Ads for a local business is reading the search terms report before it costs you another month of bad clicks. Find the irrelevant searches, add negatives, tighten your match types, and repeat. If you want a faster way to spot wasted spend without digging through the dashboard manually, Talon surfaces exactly that, designed for local business owners who need clear answers without hiring an agency.
