GroundTruth Alternatives for Local Service Businesses (2026)

What GroundTruth actually is

GroundTruth is a location-based advertising platform. The company markets a stack of targeting layers (audience, location, contextual) running across mobile, desktop, connected TV / OTT, digital audio (podcasts and streaming), digital out of home, audience-based direct mail, and social.

The platform sells through three engagement models: pure self-serve (the Ads Manager), managed service (GroundTruth's team runs the campaign for the brand), and programmatic (GroundTruth-served audiences delivered into a buyer's existing DSP).

What makes GroundTruth different from a standard programmatic DSP is the outcome-priced pricing models. As GroundTruth states in its product copy, advertisers can pay using pricing such as Cost Per Visit, GROAS (guaranteed return on ad spend), or cost per additional product sales generated by the campaign. That said, traditional CPM buys remain available across the same inventory.

How Cost Per Visit (CPV) actually works

Cost Per Visit is the pricing innovation GroundTruth is known for. Instead of buying impressions and inferring foot traffic afterward, the advertiser pays a fixed price only when GroundTruth attributes a measurable in-store visit to the ad. No visit attributed, no charge.

Attribution works by panel match. GroundTruth maintains a panel of opted-in mobile devices with location enabled. When a device that saw the ad later enters the advertiser's storefront polygon during the campaign window, the platform attributes a visit and bills. The price varies by industry: a fast-food visit clears at a lower CPV than a premium-grocery or auto-dealership visit, because the underlying lift and the value of each visit differs.

The architecture is honest in a way most programmatic models are not: the unit price is the same unit the advertiser is buying (a visit, not an impression). The trade-off is that CPV only works when the customer walks into a physical store. For service businesses where the customer never visits (the technician drives to the customer's house instead) the CPV unit does not match the business outcome.

Where GroundTruth is the right tool

Naming where the platform wins keeps the rest of this page honest.

1. Quick-serve restaurants and retail chains. A pizza chain, coffee chain, or convenience-store chain measuring incremental store visits per ad dollar is the platonic GroundTruth use case. The CPV unit lines up with the business outcome (one more customer through the door), and the self-serve Ads Manager removes the agency layer.
2. Premium-grocery and big-box retail. Foot-traffic lift studies on premium-grocery and big-box brands have been run through the same panel-match attribution for over a decade. The methodology is well-understood and the lift numbers are publishable.
3. Auto dealerships with a physical lot. A dealership measuring how many shoppers visit the lot after seeing a digital ad fits the panel-match model. CPV against the dealership polygon is the obvious unit; the GroundTruth platform owns the attribution graph.
4. Audience-based direct mail extension. GroundTruth's direct mail product extends the same location-based audience graph into addressable mail. For a chain that runs digital and mail in parallel, the audience can be defined once and delivered to both channels.

Where GroundTruth is the wrong tool for a local service business

Local service businesses (HVAC, roofing, plumbing, garage doors, pest control, electrical, lawn care) have a different problem shape than the campaigns CPV is engineered for. The customer never walks into a storefront. The technician drives to the customer. That single structural fact breaks the visit-attribution model the platform is built around.

Three structural mismatches stack against the small operator:

• No storefront, no visit, no CPV unit. CPV bills when a device that saw the ad enters the advertiser's storefront polygon. An HVAC contractor with no walk-in office has nowhere for the panel to attribute a visit to. The platform defaults to standard CPM buys for those campaigns, which removes the very thing that made GroundTruth different.
• Panel match rate against a small-audience local advertiser. The panel-match model is statistically robust at the regional or national CPG scale where the panel has thousands of matched devices per market. For a roofing contractor running a single neighborhood corridor, the matched-device pool inside that corridor is small, and attribution noise grows accordingly.
• Supply-chain take on the CPM fallback. When the campaign falls back to standard CPM, the same ANA 2023 supply-chain math applies: roughly 36 cents of every programmatic dollar reaches the consumer as working media, with the remainder going to DSP and SSP fees (around 29 percent of spend) and media-quality losses (non-viewable impressions, made-for-advertising sites, invalid traffic).

Cost Per Verified Delivery (CPVD) vs Cost Per Visit (CPV)

The two pricing models share an honest property: both bill on a verifiable unit instead of an inferred impression. The difference is which verifiable unit fits the business.

CPV (GroundTruth) bills when a panel-matched device walks into a storefront polygon. The unit is a foot-traffic visit. The business outcome it matches is incremental customers walking into a brick-and-mortar location.

CPVD (WilDi Maps) bills at $0.20 each time a real driver phone is GPS-verified moving through a corridor the advertiser leased. The unit is a driver delivery. The business outcome it matches is a service business reaching a customer who drives to and from work along a known route.

Different units, different fits. CPV is right for chains with physical stores; CPVD is right for service businesses whose customers do not walk into stores. See what is Cost Per Verified Delivery for the full architecture, and the Middleman Tax for where the standard supply chain siphons budget that CPVD does not.
