What is AIO (AI Index Optimization)?

AIO stands for AI Index Optimization — the practice of making a website's content and structure legible to large language models so they accurately represent the site in AI-generated answers. It involves adding llms.txt, proper schema markup, ai:meta tags, and explicit AI crawler permissions.

What is GEO (Generative Engine Optimization)?

GEO stands for Generative Engine Optimization — optimizing content so it is cited and recommended by AI-powered search and chat interfaces like ChatGPT, Perplexity, Gemini, and Claude. It extends traditional SEO to cover how LLMs discover, understand, and cite websites.

How does Neurobird's AI visibility audit work?

Neurobird fetches your website, runs 50+ checks covering AI crawler access, structured data, meta tags, llms.txt, ai-plugin.json, schema markup, and content signals. It scores your site 0–100 and generates a 9-file deploy bundle that fixes every identified gap.

Is Neurobird free to use?

Yes. Neurobird offers 3 free AI visibility audits per month with no credit card required. Pro and Agency plans unlock unlimited audits and the 9-file deploy ZIP download.
