What is the difference between robots.txt and llms.txt?

Think of robots.txt as your 'Access Control'-it tells crawlers which doors are locked. In contrast, llms.txt is your 'Content Curator'-it is a Markdown-formatted map that tells AI models (like Gemini and GPT-4) exactly which content is most important and how to summarise it. While robots.txt focuses on exclusion, llms.txt focuses on clarity and citation accuracy.

How does robots.txt help me stay visible in AI Overviews?

In 2026, Google uses the Google-Extended user-agent to let you choose if your content trains their models. However, to appear in AI Overviews (AIO), you must ensure your primary content remains 'Allowed' for Googlebot. Our validator checks if you have accidentally blocked the very crawlers that generate these high-visibility AI snippets.

Why should I use an llms.txt file on my website?

AI agents often struggle with 'noisy' HTML (menus, ads, and tracking scripts). An llms.txt file provides a clean, text-only version of your site’s value proposition. This reduces 'tokenization costs' for AI models, making them significantly more likely to cite your brand accurately and include your tools in their conversational responses.

Can I block AI models from training on my data but still show up in AI search?

Yes. This is known as 'Selective Governance.' You can use robots.txt to disallow agents like GPTBot (which trains models) while allowing ChatGPT-User or PerplexityBot (which browse the web to answer live user queries). This ensures you get the traffic without giving away your intellectual property for free.

Does this tool actually change my live files?

No. This is a read-only diagnostic utility. It analyses your current configuration and provides a 'Health Score' based on 2026 AI standards. You will receive a list of suggested improvements that you can then copy and upload to your server's root directory.

What is a Robots.txt File?

A robots.txt file is a text file residing in the root directory of your website. It provides instructions to search engine crawlers (bots) about which pages they can request from your site and which they should ignore. It acts as a gatekeeper for your site's crawl budget.

Why is Robots.txt Important?

Properly configuring your robots.txt prevents search engines from indexing low-value pages, admin panels, or duplicate content. It also helps manage server load by controlling crawler frequency. Errors here can be catastrophic, potentially de-indexing your entire site.
