Paying for Clicks That Never Turn Into Calls? Build a Negative Keyword List, Step by Step

Roughly a third of Google Ads spend for small local advertisers goes to search terms that were never a good fit in the first place. That is not a made-up number to scare you, it is what happens when an ad shows up for searches like “free,” “jobs,” “how to do it myself,” or a service you do not even offer. Every one of those clicks costs money, and none of them ring your phone.

The fix is not a bigger budget. It is a negative keyword list, which is simply a list of words and phrases you tell Google to ignore. Get it right and the same budget starts landing in front of people who actually want to buy. Here is how to build one, step by step.

Step 1: Look at what you’re actually paying for

Before you block anything, you need to see the real searches. Inside Google Ads there is a search terms report (Campaigns, then the Search Terms tab). This shows the exact phrases people typed before clicking your ad, which is different from the keywords you bid on.

Sort by cost, highest first. Say a Birmingham HVAC company is bidding on “AC repair” and finds it has paid for “AC repair training course,” “free AC repair,” and “AC repair jobs near me.” None of those are customers. Seeing them in black and white is the whole point of this step. You cannot fix leaks you cannot see.

Give it a couple of weeks of data if the account is new, so you are not reacting to three clicks.

Step 2: Sort the junk into buckets

Once you have the list, group the bad searches into a few plain categories. This makes the next steps faster and helps you spot patterns.

• Wrong intent: “free,” “cheap,” “DIY,” “how to,” “salary,” “jobs.” These people are not hiring anyone.
• Wrong service: things you do not offer. A shop that only does commercial work paying for “residential” searches, for example.
• Wrong location: if you serve the Birmingham metro but keep getting clicks from Huntsville or Atlanta terms, those are money down the drain.
• Researchers and students: “definition,” “vs,” “reviews of,” “reddit.”

A realistic example: a restaurant running ads for catering might find it is paying for “catering license Alabama” and “catering jobs.” Both belong in the junk buckets immediately.

Step 3: Add negatives at the right level

Now you add those terms as negatives. Google gives you a few places to do it, and the level matters more than most owners realize.

• Account level: blocks a term everywhere. Great for permanent junk like “jobs,” “free,” and “salary.”
• Campaign level: blocks a term in one campaign only. Useful when a word is bad for one service but fine for another.
• Ad group level: the most precise, for fine-tuning.

Start by building one account-level negative keyword list of the universal junk. That single list quietly protects every campaign you ever run. Deciding where limited dollars go first is its own skill, and it is worth reading our take on where a small marketing budget should go first so negatives fit into a bigger plan.

Step 4: Understand match types (this is where money leaks)

Negative keywords have match types too, and using the wrong one either blocks too much or too little.

• Negative broad match (just the words, no punctuation): blocks any search containing all those words in any order. Use it for most junk.
• Negative phrase match (“in quotes”): blocks searches with that exact phrase.
• Negative exact match ([in brackets]): blocks only that precise search.

Here is the trap. If a plumber adds the negative broad word “commercial” but also wants “commercial water heater” jobs, they just blocked their own good traffic. In that case use negative phrase or exact match instead, so you only screen out what you mean to. When you are unsure, be narrower. It is easier to add more negatives later than to win back leads you accidentally shut off.

Step 5: Make it a routine, not a one-time cleanup

New junk searches appear constantly because language is endless. The businesses that win with Google Ads treat this like brushing teeth, not a deep clean once a year.

A simple rhythm: check the search terms report every week for the first month, then every two to four weeks after that. Each visit, skim for new waste, drop it into the right bucket, and add it as a negative. Ten minutes of maintenance can protect a meaningful slice of spend.

This tidy-up pairs naturally with tracking your real return. Our guide on reading whether your Google Ads are actually making money shows what to watch once the wasted clicks are gone.

Frequently Asked Questions

Can I add too many negative keywords and hurt my ads? Yes. The most common way is using negative broad match on a word that also appears in good searches. If you block “repair” to stop “repair manual” clicks, you also lose “AC repair.” Use phrase or exact match for anything that could show up in a real customer’s search, and review your impressions after big additions to make sure traffic did not fall off a cliff.

What if a search term is borderline, not clearly good or bad? Leave it for a cycle and watch it. If a term keeps costing money over a few weeks with no calls, form fills, or bookings, block it. If it occasionally converts, keep it. Negatives are reversible, so you are never locked in. When in doubt, let a little more data pile up before deciding.

Do negative keywords matter if I run Performance Max or mostly Local Services Ads? They work differently there. Performance Max accepts a negative list but with less granular control, and you may need to request account-level negatives through support. Local Services Ads for Birmingham contractors run on a pay-per-lead model instead, so you dispute bad leads rather than blocking keywords. Match the tactic to the ad type you are actually running.
