GEA: What is Generative Engine Advertising? (And how developers can profit from it
GEO optimizes brands for AI visibility. GEA is how those brands advertise in AI tools. Learn what Generative Engine Advertising means for developers—and how Idlen lets you earn from it.
GEA: What is Generative Engine Advertising?
You've heard of GEO (Generative Engine Optimization)—the new SEO for AI. But there's another acronym you need to know: GEA (Generative Engine Advertising).
If GEO is how brands get found by AI, GEA is how they pay to be found. And for developers who use AI tools daily, GEA represents a new passive income opportunity.
Let's break it down.
The Rise of GEO: SEO for the AI Era
First, some context. Traditional SEO optimizes content for Google's search results. Generative Engine Optimization (GEO) optimizes content for AI-generated answers.
Why does this matter? Because AI is eating search:
- ChatGPT reached 800 million weekly active users by late 2025
- Gartner predicts a 25% decline in traditional search traffic by 2026
- 71% of Americans already use AI search to research purchases
The goal of GEO isn't to rank on page one—it's to get cited, quoted, or recommended when an AI answers a question.
Brands are scrambling to adapt. Tools like GetMint.ai have emerged to help companies track their AI visibility, measure citation frequency, and optimize their content for LLM retrieval. It's a whole new discipline.
But here's the thing: visibility alone doesn't pay the bills. Brands still need to advertise.
Enter GEA.
What is GEA (Generative Engine Advertising)?
Generative Engine Advertising (GEA) refers to advertising formats displayed directly within AI-powered tools and responses.
Think of it as the natural evolution of search advertising:
| Era | Optimization | Advertising |
|---|---|---|
| Web 1.0 | Directory listings | Banner ads |
| Web 2.0 | SEO (Google) | SEA (Google Ads) |
| AI Era | GEO (AI visibility) | GEA (AI advertising) |
Where traditional display ads appear on websites and search ads appear in Google results, GEA ads appear inside AI interactions:
- Sponsored suggestions in ChatGPT responses
- Product recommendations in Perplexity searches
- Contextual ads during AI coding assistant usage
- Native placements in conversational AI interfaces
The GEA Landscape in 2026
GEA is no longer theoretical. Major platforms are actively deploying it:
ChatGPT Ads (OpenAI)
In January 2026, OpenAI officially launched advertising for ChatGPT free-tier users. Key details:
- Ads appear at the bottom of responses in a labeled "Sponsored" box
- Targeting is based on conversation context, not user tracking
- Baseline CPM reportedly set at $60 (vs. $2-10 for traditional display)
- Paid tiers (Plus, Pro, Enterprise) remain ad-free
OpenAI projects $1 billion in ad revenue for 2026, growing to $25 billion by 2029.
Google Gemini Ads
Google confirmed plans to bring advertising to Gemini in 2026. Given Google's advertising DNA, expect sophisticated targeting and measurement.
Perplexity Sponsored Results
Perplexity is testing sponsored follow-up questions and paid source placements. Unlike traditional ads, these are contextually generated and clearly labeled.
The Bigger Picture
eMarketer projects AI-driven search ad spending will surge from $1.1 billion in 2025 to $26 billion by 2029—a 23x increase.
Why GEA CPMs Are So High
You might wonder: why would brands pay $60 CPM for AI ads when display ads cost $2-5?
Three reasons:
1. Intent is Everything
When someone asks ChatGPT "what's the best project management tool?", they're showing high purchase intent. That's worth more than a passive banner impression.
2. Context is Perfect
GEA allows hyper-relevant targeting based on the conversation itself. A developer asking about React state management sees developer tool ads—not random display ads.
3. Attention is Focused
Users engaging with AI are actively reading and thinking. Compare that to banner blindness on cluttered websites.
For advertisers, GEA represents premium inventory in a world of attention scarcity.
The Developer Opportunity: Earning From GEA
Here's where it gets interesting for developers.
Brands are pouring billions into GEA. That money flows to the platforms—OpenAI, Google, Perplexity. But what if you could capture some of it?
That's exactly what Idlen does.
How Idlen Works
Idlen is an extension for VS Code, Cursor, and Chrome that displays developer-relevant ads during AI tool wait times:
- Install the extension in your IDE or browser
- Use AI tools normally (ChatGPT, Claude, Cursor, Copilot, etc.)
- Ads appear during "thinking" time—the 2-15 seconds when AI generates responses
- Earn revenue share from every impression
No extra work. No lifestyle change. Just passive income from the AI interactions you're already having.
The Numbers
| Usage Level | Daily AI Interactions | Monthly Earnings |
|---|---|---|
| Light | 20-50 | €15-30 |
| Regular | 50-150 | €30-60 |
| Heavy | 150-300 | €60-100 |
| Power User | 300+ | €100+ |
For developers who live in AI tools like Cursor, €50-100/month is realistic with zero additional effort.
Why This Works
- High CPMs: Developer-focused ads command premium rates (similar to GEA pricing)
- Perfect targeting: Idlen reads only

- Privacy-first: No code access, no prompt reading, no tracking
GEO + GEA: The Complete Picture
To understand the AI advertising ecosystem, you need both pieces:
GEO is what brands do to get visibility. They optimize content, build authority, and use tools like GetMint.ai to track how often AI cites them.
GEA is what brands do to accelerate visibility. They pay for sponsored placements, contextual recommendations, and priority positioning in AI responses.
For developers, this creates an opportunity on both sides:
- Create content optimized for GEO (your technical blog, documentation, open-source projects)
- Earn from GEA through tools like Idlen that share advertising revenue
The Future of GEA
We're at the beginning of a massive shift. A few predictions:
1. GEA Will Become Essential
Just as SEA became mandatory alongside SEO, GEA will become essential for brands competing in the AI era. You can't rely on organic AI visibility alone.
2. New Ad Formats Will Emerge
Beyond text-based sponsored responses, expect:
- Voice-based GEA in AI assistants
- Visual product placements in image generators
- Interactive demos within AI coding tools
3. Developer-Focused GEA Will Grow
The developer market is valuable (high income, high influence). Expect more platforms targeting developers with GEA—and more opportunities to monetize.
4. Privacy Will Be a Differentiator
Users are sensitive about AI and data. Platforms that respect privacy while delivering relevant ads (like Idlen's approach) will win trust.

FAQ
What is GEA (Generative Engine Advertising)?
GEA stands for Generative Engine Advertising. It's advertising displayed within AI tools and chatbots—the paid equivalent of GEO (Generative Engine Optimization). Where GEO gets you organic AI visibility, GEA gets you paid placements.
How is GEA different from Google Ads?
Traditional search ads appear in Google results. GEA ads appear inside AI-generated responses. The targeting is based on conversation context rather than search keywords, and CPMs are significantly higher due to better intent and attention.
Can I opt out of GEA as a user?
On most platforms, paid subscriptions remove ads. ChatGPT Plus/Pro users don't see ads. With Idlen, you control when ads appear and can pause anytime.
How much can developers earn from GEA?
With Idlen, developers earn €30-100/month depending on AI tool usage. Heavy Cursor users (300+ daily interactions) can exceed €100/month.
Is GEA going to replace traditional advertising?
Not replace—complement. GEA captures the growing share of attention moving to AI interfaces. Brands will need both traditional ads and GEA as part of a complete strategy.
How do I track my brand's GEO performance?
Tools like GetMint.ai track citation frequency, share of voice, and sentiment across major LLMs including ChatGPT, Claude, Gemini, and Perplexity.
Conclusion
GEO and GEA represent the future of marketing. As AI becomes the primary interface for information and commerce, brands will pay premium prices to be present in those interactions.
For developers, this creates a unique opportunity. You're already using AI tools constantly. With Idlen, you can earn from the GEA boom without changing how you work.
The AI advertising gold rush is here. Make sure you're not leaving money on the table.
