A 20-minute weekly audit

Copy these questions (one by one or all 5), replace the brackets and ask them in ChatGPT and Perplexity every Monday. Note whether you appear, who gets cited and which page they use.

5 questions for your weekly audit

  1. Which companies in [Paraguay/Ecuador] offer [your service] for [your customer]?
  2. What is the best option for [specific problem] in [city]?
  3. How much does [your service] cost in [country] in 2026?
  4. What does [regulation or procedure] require and who helps you comply?
  5. Compare [your company] with other options for [use case].

Self-check: can you be cited?

GEO checklist for a page you want cited

Your page: 0/9 · Hard to get cited
priority: sourced figures and answer in the first sentence

Tick what your page already does. Priority puts first what makes content verifiable (sources and data), the largest effect in the study.

How to read it: 0 to 3, hard to get cited; 4 to 6, partial base; 7 to 9, ready. Priority puts citing sources and verifiable data first, the tactics with the largest effect in the study; then structure and the technical layer.

A 6-week plan

Frequently asked questions

What is GEO (Generative Engine Optimization)?

The practice of optimizing your content and technical signals so AI answer engines (ChatGPT, Gemini, Perplexity) cite your company when someone asks about your category.

What is the difference between SEO and GEO?

SEO ranks your pages in a list of links; GEO aims for your content to be the cited source inside the generated answer. They share the foundation (useful content and solid technicals) but change content format and measurement.

How do I know if ChatGPT mentions my company?

Ask it directly about your category across several sessions, note whether you appear and which sources it cites, and repeat weekly. Complement it with referral traffic from domains like chatgpt.com or perplexity.ai in your analytics.
