Disclosure: we're Advertise on AI, and we're one of the agencies below. We've kept every other entry to what each agency says on its own site, linked each one, and left out anything we couldn't confirm. If you run one of these agencies and something has changed, email hello@advertiseon.ai and we'll update it.

"Not listed" means the agency's own pages didn't mention it when we checked, not that it can't do it. Ads in Google AI Overviews, AI Mode and Copilot come from regular Google Ads and Microsoft Advertising campaigns; advertisers can't target those placements directly, and most of these agencies also run those platforms as general paid search.
How to choose
- Ask what's included in the fee. Some quotes are management only, with media on top; others include both. Ask for the split in writing.
- Ask for a minimum that fits your test. ChatGPT's own floor is $25 a day. A $5,000 monthly retainer makes sense for a large program, not a first test.
- Ask how they measure organic visibility. A useful answer is a fixed set of prompts sampled on a schedule across assistants, reported as share of answers, with paid and organic counted separately.
- Be wary of guarantees. Nobody can guarantee your business is named inside an AI answer. Ads sit below it, labeled.
- Ask whether they cover more than ChatGPT. The same questions are asked in Google AI Mode, Copilot, Gemini and Perplexity.

Not sure you need an agency?
You may not. We lay out when running Ads Manager yourself or using a tracking tool is the better call in ChatGPT ads: do it yourself, use a tool, or hire an agency.
