Ads on ChatGPT: The New Channel
OpenAI launched advertising on ChatGPT in February 2026, creating a completely new channel:
- Format:contextual ads integrated into responses — look like organic recommendations
- Segmentation:based on the context of the conversation, not demographics
- Challenge:rupture in the “AI trust contract” — users trust that answers are impartial
Ads alongside Google's AI Overviews rose from 5.17% to 25.5% in Q1 2026. The monetization of AI via advertising is just beginning — it's an opportunity for early adopters.
AI Ads Strategy for 2026
How to adapt to the new scenario:
- Invest in creatives:When AI controls targeting and bidding, creative is your biggest differentiator
- Diversify channels:Don’t just depend on Meta and Google — test ChatGPT Ads, Perplexity, TikTok
- Impeccable tracking:AI only optimizes well with accurate data —Consent Mode + server-sideis mandatory
- First-party date:Build your own lists — Customer Match and Lookalikes depend on your data
- Quick test:AI generates variants in seconds — test 10x more than before
The traffic manager of 2026 is acreative director + data analyst, not a platform operator.

For e-commerce with a large catalog, yes — PMax performs well in Shopping and Discovery. For B2B services with a long funnel, results are mixed. The key is to feed it with quality conversion data and give the AI time to learn (2-4 weeks).
For prospecting and scaling, Advantage+ already outperforms manual campaigns in most cases. For remarketing with very specific messages and niche audiences, manual campaigns may still work better.
If you are an early adopter and your audience uses ChatGPT, test with a small budget. The channel is new, CPMs must be low and competition is lower. Historically, early adopters of new channels (Facebook 2012, TikTok 2020) reap the best results.

Fatal AI Marketing Mistakes (and How to Avoid Them)
After analyzing 200+ AI marketing implementations, these are the mistakes that cost the most:
- Publishing AI content without human review: Google detects and penalizes "AI slop" — generic, repetitive content with no real value. Solution: IA faz o rascunho, human edita, adds real experience and personality.
- Automating before understanding: If you don't know how to do email marketing manually, automating only scales problems. Learn the fundamentals first, then automate.
- Ignoring data: AI generates 10x more content, but if you don't measure results, you don't know what works. Set up GA4, Meta Pixel and dashboards before scaling.
- Generic copy: "Descubra como..." e "Neste artigo voce vai aprender..." — phrases every AI generates. Use voz de marca, dados especificos e experiencias reais to se diferenciar.
- Not segmenting: Enviar a mesma mensagem to todo mundo is wasting AI's greatest power: personalization. Segment by behavior, not demographics.
Professionals who avoid these 5 mistakes report 3-5x more results than those who use AI superficially.
