Question: Is there a platform that allows me to target ads to people based on their location, such as visits to specific stores or restaurants?

If you're looking for a platform that lets you target ads to people based on their location -- for example, visits to particular stores or restaurants, Spatial.ai could be a good choice. It offers a range of tools including PersonaLive, Proximity and FollowGraph to let marketers segment customers by social, mobile and web behavior, score neighborhoods by social interest, and assess consumer interest in brands by geography. It's geared for retail and restaurant customers, but offers potentially useful insights while protecting privacy.

Another strong contender is AdTheorent. The platform uses machine learning to offer predictive targeting, geo-intelligence and cross-environment mapping. It can help advertisers find high-probability converters and target them with ads. AdTheorent stresses privacy with options that banish cookies and one-to-one targeting, so it's a good choice for restaurants and retailers.

Its platform includes tools like predictive modeling, omnichannel media buying and Sonata Location Intelligence for targeting by geography. It's designed to make advertising more intelligent with data-driven insights and to optimize media spend.
