13 Best ChatGPT Ads Agencies in Madrid (2026)
ChatGPT Ads is still a relatively new advertising channel, which makes agency selection especially dependent on practical platform experience, measurement capabilities, and the ability to connect campaigns with existing paid media activity. Madrid businesses can choose from local specialists, Spanish performance agencies, and global media groups with direct access to OpenAI's advertising ecosystem.
The right provider will depend on campaign scale and wider marketing needs. Smaller and mid-sized companies may prefer agencies that combine ChatGPT Ads with PPC, GEO, landing pages, and conversion tracking, while larger brands may need broader media planning and international campaign management. Comparing each agency's service scope, Madrid coverage, reporting approach, and experience with conversational advertising can help narrow the list to the most suitable option.
