Geofencing advertising companies, judged on evidence

How to vet a geofencing advertising company

1. Make them separate fee from media. Ask for the fee and the media budget as two numbers in writing. Geofencing is often quoted as one blended monthly figure, which hides both the markup on impressions and the actual working budget. A vendor unwilling to split the two is selling opacity, and you cannot audit what you cannot see.
2. Ask where the location data comes from. Ask which supply-side platforms and data providers the campaign uses, whether targeting is live geofencing or historical geofencing built from past location data, and how devices are matched to a boundary. Location data has drawn steady regulatory attention, so a provider who cannot describe their data chain is a compliance risk as well as a performance one.
3. Pin down what counts as a result. Impressions and click rates are close to meaningless on display inventory. Ask which outcome is being measured: a form fill, a call, a store visit, or a walk-in attributed by a device-matching study. Then ask what the measurement method is and what its known error looks like, before the first invoice.
4. Insist you own the accounts and the tags. The ad accounts, conversion tags and any first-party audience lists should live in entities your business controls, with the agency granted access. Vendors who run everything inside their own platform can take the campaign history with them the day the relationship ends, which quietly raises the cost of ever switching.

What actually moves the price

Three things set the bill and only one of them is the agency. The first is the size and density of the fences. A campaign covering a handful of tight boundaries around specific buildings reaches far fewer devices than one covering a metro, so tight targeting costs less in media but usually more per outcome. The second is inventory quality: premium app and connected-TV placements cost multiples of remnant display, and a cheap monthly number almost always means the cheap end of the exchange.

The third is measurement. Attribution studies that match exposed devices to later store visits are a real analytics product with a real cost, and a provider offering them for free is generally not doing them. Buyers routinely discover that the difference between two quotes was not skill at all: one included measurement and real inventory, the other did not, and the cheaper one had no way to prove anything happened.

The questions that separate operators from resellers

A large share of firms selling geofencing are resellers sitting on a white-labelled platform. That is not automatically bad, but it changes what you are buying and what you should pay. Ask directly whether the media is bought in-house or through a partner, who writes and designs the creative, who builds the landing page, and who is on the account day to day. A reseller with a good strategist can be a fine choice; a reseller charging in-house rates for a dashboard login is not.

Ask for the exit terms too. How much notice is required, what happens to the audience data, and can the campaign be paused without penalty if a season ends early. Geofencing is often bought for a specific window, an event, a launch, a competitive push, and contracts written for open-ended retainers fit that badly. Firms that publish their minimums and their terms make the comparison easy, which is the whole reason this index records who does.

Questions people actually ask

Is geofencing different from ordinary local ad targeting?

Yes, in precision and in data. Standard platform targeting works from a radius or a named region. Geofencing draws custom boundaries, often around individual buildings, and some vendors also build audiences from devices that were inside a boundary in the past. That extra precision is the reason it is priced above ordinary local display.

What is a realistic minimum monthly spend?

Providers vary widely and many will not print a floor. Ask for the stated minimum in writing before the first call, because a campaign spread too thin across too many fences produces too few impressions per device to move anything, and that outcome looks like failure when it was really underfunding.

Can geofencing prove someone visited the store?

Only through a formal attribution study, and only within its stated margin of error. Ask which vendor performs the study, what the matched sample looks like, and whether a control group is used. Treat any store-visit claim made without a named methodology as marketing rather than measurement.

Are there privacy rules to worry about?

Location data is among the most scrutinised categories in US consumer privacy enforcement, and several state privacy laws create obligations around sensitive data and opt-outs. Ask the provider how consent flows through their supply chain and whether they can honour deletion and opt-out requests. Put the answer in the contract.
