GEO (Generative Engine Optimization) is the practice of optimizing your brand’s visibility in generative AI answers like ChatGPT and Gemini.
We monitor the leading LLMs on the market
The new starting point
When someone asks about your category, AI recommends 2 or 3 brands and discards the rest. Either you’re in that answer, or you don’t exist.
Based on market reviews, these are the most recommended options:
1.Your brand
Mentioned · #1The most complete option for SMBs in the region
2.Competitor A
Good alternative with flexible plans
3.Competitor B
Budget option for small teams
Lumen runs these conversations automatically and shows you exactly where each brand appears.
AI doesn’t show ten links: it recommends a handful of brands. Whoever is left out becomes invisible.
Less than 10% of top Google results appear in LLM answers. It’s a different game, with different rules.
GEO is the new SEO. The brands and agencies that work on it first keep the recommendation.

See who wins each conversation in your category and how much voice your brand has against the competition.

Prompts in Spanish and Portuguese with regional variants. Pay in local currency with Mercado Pago.

The GEO gap
Less than 10% of top Google results are cited in LLM answers.
Seer Interactive, 2025
The value of search traffic migrating to AI answers grows year over year.

FAQ
SEO optimizes so Google finds you. GEO (Generative Engine Optimization) optimizes so ChatGPT, Gemini, and other LLMs recommend you when someone asks about your category. They’re different games: less than 10% of top Google results appear in AI answers.
You define prompts that represent how your customers search for solutions (for example, “what’s the best CRM in Argentina?”). Lumen runs them on ChatGPT and Gemini at your plan's frequency and analyzes each answer: whether your brand appears, in which position, with what context, and which competitors are mentioned.
Both. Beyond monitoring, Lumen generates GEO Actions: it detects what your digital presence is missing and uses AI to draft the content to fix it — articles, FAQs, and technical improvements ready to publish.
The Agency plan gives you a multi-client dashboard to monitor up to 5 brands at once, exportable PDF/CSV reports for your meetings, and a prospecting tool that generates automatic GEO audits so you can win new clients with hard data.
Lumen is designed for Latin America: prompts in Spanish and Portuguese with regional variants (Argentina, Mexico, Colombia, Brazil, and more). The platform is available in Spanish and Portuguese.
We accept Mercado Pago and you can pay in local currency. There are no lock-in contracts: cancel anytime from the platform and keep access until the end of the paid period.
