Facebook Has No Negative Keywords. Use These 5 Filters

Published September 23, 2026 · Curbside Websites

Why doesn't Facebook have negative keywords?

Because nobody typed anything.

Google Ads works off a search query. Someone types "water heater leaking" and you bid on it. Negative keywords exist so you can say "but not if they typed how to fix or jobs or the name of a town 40 minutes away." You are filtering intent that already exists.

Facebook is the opposite. Nobody went looking for you. You interrupted a guy scrolling on his lunch break. There is no query to block, so there is no list to block it with.

That does not mean you have no control. It means your controls live somewhere else. Most facebook ads wasted spend for local trades comes from four places, and none of them are fixed by keywords.

Where does facebook ads wasted spend actually come from?

In local service accounts, it is almost always one of these:

• Geography that is too loose. A 25 mile radius around a metro includes towns you will never drive to.
• Placements you never chose. Audience Network and some Reels inventory can eat budget with taps that were basically accidents.
• Ads that are too vague. "Quality service at a fair price" invites everyone, including people who want a free look.
• No screening before the lead hits your phone. A one-tap instant form sends you a name and a number, nothing more.

Fix those four and you have done the equivalent of a solid negative keyword list.

What replaces negative keywords on Facebook?

1. Geography, set the strict way

This is the closest thing to a negative keyword on the platform, and it is the one most people set wrong.

• Set the location type to people living in this location. The default often includes people who were recently in the area. You do not want tourists.
• Drop pins on the towns you actually serve instead of one fat radius around your city.
• Use the exclude field. If you will not cross a bridge or a river or a toll, exclude the towns on the other side by name.

A painter working three suburbs should have three pins, not one 20 mile circle that includes a city he never bids in.

2. Exclusion audiences

Facebook cannot block words but it is very good at blocking people. Build these once:

• Past customers. Upload your invoice list. Exclude it from acquisition campaigns so you stop paying to reach people who already have your number. Run a separate, cheap maintenance ad to them instead.
• Job applicants and employees. If you have ever run a hiring ad, exclude everyone who engaged with it from your service ads.
• People who already converted. Exclude anyone who submitted a form in the last 30 days. Otherwise you keep paying to re-annoy a guy you already booked.

3. Placement control

Advantage+ placements are fine to start. They are not fine to leave alone.

After a few hundred dollars, open the breakdown by placement. If Audience Network is generating half the clicks and none of the calls, turn it off. Same with any placement where cost per lead is triple everything else. This is the single fastest cut most local accounts can make.

4. Ad copy that disqualifies on purpose

This is the real answer, and it is the one nobody wants to hear. On Facebook, your creative is your negative keyword list.

A vague ad is a broad match keyword. A specific ad is exact match. Put the filters in the ad itself:

• Name the town. "Serving Medford and Malden." People outside it scroll past.
• Name the exact job. "Whole home repipe" pulls a different person than "plumbing services."
• Name a starting price or range. "Most drain clearings run $250 to $400." Bargain hunters self-select out before they cost you a click.
• Name who it is not for. "We do not do mobile homes" or "minimum job size $500" saves you three phone calls a week.

Yes, you will get fewer leads. That is the point. Cheap leads that never book are the most expensive thing in your ad account.

5. A form or page that screens

If you use instant forms, choose the higher intent version that makes people review before submitting, and add two qualifying questions. Not ten. Two.

Good ones: "What town is the property in?" and "Is this a rental or your own home?" or "When do you need this done?" Anyone who will not answer two questions was never going to sign an estimate.

If you send traffic to your site, send it to the specific service page, not the homepage. The page finishes the filtering the ad started.

Is there anything on Facebook that works like a blocked word list?

One thing, and it is not in Ads Manager. Your Facebook Page settings have a blocked words list for comments. That is worth ten minutes.

Add competitor names, profanity, and the phrases that show up under every contractor ad. It will not save budget directly, but it keeps your ad comments from turning into a place where three other guys post their numbers under your post. That is real leakage, just a different kind.

How do you find the waste without a search terms report?

You build your own. Facebook will never tell you which lead was junk, so you tell yourself.

1. Name every ad something you will recognize on the phone. "Repipe-Medford-Truck-Photo."
2. Keep a simple spreadsheet: date, ad name, town, job type, booked yes or no, ticket size.
3. Once a month, sort by ad name. You will see which creative brings tire-kickers and which brings jobs.
4. Kill the bad ad. Write two more versions of the good one.

Then check the breakdowns inside Ads Manager for placement, region, and age. Region is the one that surprises people most. You will often find a third of your spend went to a town on the edge of your radius that has never once turned into work.

What should you do this week?

• Switch your location setting to people living in this location.
• Exclude two or three towns you will not drive to.
• Pull the placement breakdown and turn off anything with clicks and no leads.
• Rewrite one ad to include your town, your exact service, and a starting price.
• Add two questions to your lead form.

That is an hour of work and it does more than any keyword list would have. The goal on Facebook was never to block bad searches. It is to write an ad that the wrong customer scrolls right past.

Common Questions

Can I add negative keywords to Facebook ads at all?

No. There is no negative keyword field anywhere in Meta Ads Manager because Facebook ads are not triggered by a search query. The closest equivalents are location exclusions, exclusion audiences, and placement controls.

Do detailed targeting exclusions still work on Facebook?

Some interest and behavior exclusions still exist, but Meta has removed many of them and the algorithm often performs better with broad targeting plus strong creative. Lean on geography, exclusion audiences from your own customer list, and ad copy that disqualifies the wrong people.

Should I turn off Advantage+ placements to cut wasted spend?

Not right away. Let it run until you have enough data to open the placement breakdown, then turn off any placement that produces clicks and no booked jobs. Audience Network is the usual first thing to cut for local service businesses.

Why are my Facebook leads worse quality than my Google leads?

Because Google leads already raised their hand and Facebook leads did not. Facebook interrupts people, so the ad and the form have to do the qualifying that a search query does on Google. Add a price range and two screening questions and quality jumps.

Does putting prices in my ad hurt performance?

Your cost per lead usually goes up and your cost per booked job usually goes down. Fewer people click, but the ones who do already know roughly what the work costs, which means less time on the phone with people who were never going to hire you.
