If you run local Google Ads campaigns, you’ve probably used radius targeting at some point.
It seems convenient: pick a point on the map and draw a circle — 5 miles, 10 miles, 20 miles — around your business.
Easy, right?
But radius targeting comes with a hidden limitation that many advertisers don’t realize:
You can see the data inside the radius… but you can’t act on it.
And that can quietly limit your ability to optimize your campaigns.
When you target a radius in Google Ads and open the Locations report, your radius usually appears as a single row.
At first glance, it looks like you have no detailed geographic data.
However, Google does allow you to dig deeper.
If you go to:
Insights & reports → When and where ads showed → Matched locations
…and then click on the radius row, you can use “Narrow by” to break the data down by:
So yes — the detailed data does exist.
You can see which areas inside the radius generate impressions, clicks, and conversions.
But here’s the catch.
Even though Google shows you the data, you can’t actually optimize those sub-areas directly when you’re using radius targeting.
Inside a radius target, you cannot:
Everything inside the radius is treated as one single targeting unit.
So even if the data shows that one neighborhood converts three times better than another, your campaign can’t react to that information.
You’re stuck treating the entire circle the same way.
Instead of targeting a single radius, you can target the individual ZIP codes or neighborhoods that make up that area.
You’ll still cover the same geographic region — but now each area becomes its own optimization unit.
In the Locations report, each ZIP code or neighborhood appears as a separate row with its own data:
Now you can actually take action on what the data tells you.
You can:
Same coverage.
Much more control.
Transitioning from radius targeting to ZIP codes is straightforward.
1. Use the map inside Google Ads location targeting, or just ask your handy AI to generate all ZIP codes inside your current radius.
2. Add those ZIP codes as targeted locations in your campaign (you can paste many at once).
3. Keep your radius targeting active temporarily as a safety net.
4. Once performance data starts appearing by ZIP code, remove the radius target.
Now every location becomes something you can optimize individually.
Radius targeting isn’t useless.
It’s quick and easy to set up.
But it limits one of the most powerful advantages of digital advertising: the ability to optimize based on data.
While Google Ads does allow you to view granular geographic data inside a radius, it doesn’t allow you to act on it.
By targeting ZIP codes or neighborhoods instead, you turn location data into something you can actually optimize.
And that’s when local campaigns start getting smarter.
