Lithiumpr works on brand visibility in ChatGPT, Gemini and Perplexity with a three-step method: measure, with real questions, the percentage of answers in which the brand appears; publish the answers that are missing; and earn presence in the sources AI cites, such as directories, media and reviews. In a recent case, a Spanish-language wellness app went from appearing in 4.8% to 27.8% of answers in five days, and reached first place on Perplexity for four questions.
What is GEO, or AI visibility?
GEO (generative engine optimization) is the work of making a brand appear when someone asks an AI what to buy or whom to hire. It is different from SEO: a search engine shows ten results and a second page; an AI answer names three or four options, and if yours is not among them, you do not exist for that person.
Why does a public relations agency do GEO?
Because AI relies mostly on what others say about a brand. In our measurement of PR agencies in Mexico, the most cited sources were directories such as Sortlist and Clutch, LinkedIn and news outlets. Earning those mentions is public relations work: press, reviews, profiles and reference content.
How does Lithiumpr work on AI visibility?
- Measurement. We ask ChatGPT, Gemini and Perplexity the questions your customers would ask, several times each, and measure how often you appear, in what position and who appears instead of you.
- Reference content. We publish on your site the best answer to every question where you are missing, with verifiable data.
- Third-party sources. We work on the directories, reviews, media and profiles that AI already cites in your category.
- New measurement. We repeat the same questions to show the before and after with data.
What results can you expect?
Perplexity, which searches the web in real time, reacts within days. ChatGPT and Gemini answer mostly from what they have already learned and take months to change. That is why we do not promise to appear by a certain date: we guarantee the work and the measurement, and we report changes for each model separately.
How do you find out if your brand appears today?
