Geofencing

A shape on a map, and what it really controls

Phones and computers report an approximate location, and ad platforms let you act on it. You draw the shape, the platform keeps your ads inside it. A mobile dog groomer who will drive twelve miles and no further stops paying for clicks from two counties over, and on a small budget that alone can be the difference between a full week and a wasted one.

One detail catches owners out. Most platforms let you choose between people who are physically in the area and a wider setting that also picks up people showing interest in it while sitting somewhere else. Those are two different audiences worth two different amounts. A vacation rental cleaner wants the person standing on the island. A charter captain probably wants the family two states away planning next spring's trip.

There is also a tighter version some vendors sell: fence a competitor's parking lot, a stadium, or a trade show floor, and advertise to the phones that were there. It is a real technique and it is easy to oversell. Having been near a place is not the same as wanting what you sell, and the smaller you draw the fence, the smaller and stranger the audience gets.

A fence does not earn you a ranking

This is the confusion that costs owners real money. Drawing a radius decides who gets shown a paid ad. It does nothing for where you rank in the map results, because that side of search weighs how far the searcher is from your actual business location, and no boundary you draw changes your address.

So a company advertising into a town twenty minutes up the road can be visible there all day in the sponsored results and still be nowhere in the local map results for the same search. Ads rent that reach for as long as you pay for it. They do not build it.

The other tradeoff is size. Draw it too tight and the account never gathers enough volume to be managed well. Draw it too wide and you are buying clicks from people you would never drive to, then paying again in time to quote work you do not want. The right shape is usually the area you would take an ordinary job in at your ordinary price, and setting that line honestly is part of building an account, which is the work described on our Google Ads page.

Terms that come up when you draw the map

If you travel to your customers rather than seeing them at a storefront, you are a service area business, and that shapes both where you set the fence and how your listings should be filled out. The distance side of local rankings goes by the proximity ranking factor, which is the part a fence cannot touch. And the reason a sloppy fence hurts at all is that every wasted click still charges you the going cost per click.
