Google Ads can target within 1km of a business

Google Ads can target within 1km of a business's own address, a small enough circle to cover the handful of streets that actually reach it. Very few accounts go that far.

An account we run proved what that setting is worth. Tightening the geographic targeting to the area customers can actually reach from pushed cost per click up, and pushed conversions up by a lot more.

Google also auto-upgraded a large share of Search campaigns to its AI Max automation this September. The deadline did not move. Some of what switched on works against a tight catchment by default, unless someone is watching for it.

How precise can Google Ads location targeting actually get?

The floor is 1km. Google Ads will not accept a radius smaller than that around a pinned address; the limit comes from the platform's own privacy thresholds and minimum audience size. That works out to roughly the handful of streets immediately around a business's own door.

Getting an ad to actually stay inside that circle needs a second setting, easy to miss because it sits one menu deeper. Google Ads offers two ways to read a targeted location: Presence, which keeps the ad in front of people who are in, or regularly in, the area; and Presence or interest, which also reaches anyone who has searched about the area or shown interest in it, wherever they are actually standing when they search. Presence or interest is the default.

Someone typing "plumber Andheri" from Thane, 40 minutes away, can be shown an Andheri plumber's ad purely because the words match, whatever the radius is set to. Webzenia checks both settings, the radius and the reach type, on every Google Ads account it runs. Together they decide whether a catchment drawn on a map is the catchment the ads are actually reaching.

What we found on this account

The business serves a defined local area. Leads arriving from roughly 10km outside it rarely turned into real work: nobody was travelling that far in for what the business sells. We tightened the geographic targeting to match where its actual customers can come from, well before AI Max existed.

Cost per click went up. The other cost metrics rose a little too. Conversions went up by a lot.

The clicks that used to arrive from that outer ring were rarely from people who could ever become customers. Removing them left a smaller audience that cost more per click and converted far better, because what remained was people close enough to actually visit.

No client name, industry or city is attached. What travels beyond it is the pattern: a catchment drawn to match where customers can physically reach from outperforms a catchment drawn to match where the population happens to be largest.

AI Max can widen the same radius a business just tightened

AI Max automates Search campaigns. It folds wider keyword matching, AI-written ad text and geographic-intent matching into one campaign setting, and it is now the default for every new Search campaign. In September, Google auto-upgraded two more things onto it: Automatically Created Assets and campaign-level broad match, on every live Search campaign that had not opted out. Nothing needed to be clicked for any of it to switch on.

The newest piece of that automation works against geographic discipline by design. Locations of Interest matches a search to the place named inside it, even when the person searching is somewhere else entirely. Someone searching a rival showroom's Andheri address from three suburbs away can now be shown that showroom's ad on the strength of the words alone, no matter what the radius is set to.

None of this caused the result on the account described above. That account tightened its geography before AI Max existed, through targeting alone. No automated bidding was involved. What AI Max changes is the workload afterwards: an account that has already been narrowed now has a live setting working to widen it again, switched on by default, on a schedule Google fixed and has not moved.

Google reports an average of 7% more conversions or conversion value, at a similar cost, for advertisers who adopt the full AI Max feature suite deliberately. That figure describes accounts that already had negative-keyword discipline and landing-page testing in place before switching everything on. September's auto-upgrade does not install any of that groundwork; it only switches the settings on.

What we check on an account like this

We check three things first. The Automatically Created Assets Google generated are read line by line and kept, edited or turned off, never left running untouched by default. The wider search terms broad match can now match against are read every week while the upgrade beds in, because a negative-keyword list sized for a narrower match type will not cover the broader one by itself. The radius and the Presence setting are checked against the business's real catchment, the same audit that produced the result described above.

None of this is guaranteed to repeat on a different account. Every business runs on a different catchment, a different keyword set, a different starting point. What we commit to is the audit itself: the settings checked, the search terms read every week, the account measured against its own numbers before and after, never against Google's published average.

Where hyper-local precision pays off most

A business with a defined local catchment, a shop, a clinic, a service radius that stops well short of the whole city, has the most to gain from getting these two settings right. That is who this is for. A national or online-first brand loses little by leaving the radius wide; a business whose customers have to physically walk in loses a great deal.

Webzenia checks both settings, the geography and the AI Max defaults sitting on top of it, as part of every Google Ads management account it runs. A working marketing analytics setup is what actually shows whether a tightened catchment is converting, not just running quieter.
