Just spent the last week obsessing over how AI crawlers interact with content sites. Holy complexity, Batman.

Here's the thing nobody talks about: LLMs are scraping everything. Your carefully crafted content? Being digested by GPT, Claude, Gemini, you name it. And you have zero control unless you explicitly set boundaries.

I run a small SaaS tool, and we noticed our blog posts showing up in weird AI summaries without attribution. That's when I realized most people don't even know about llms.txt files - basically robots.txt for AI crawlers.

The concept is simple: specify which AI systems can access your content, set rate limits, define allowed paths. But implementing it? Total nightmare if you're not technical. XML formatting, syntax errors, testing endpoints...

So I built a generator that just handles it. 3 fields: your domain, which crawlers to allow (or block), and any path restrictions. Outputs a clean llms.txt file ready to deploy.

Early metrics: 47 websites using it in the first week. Most common use case? Preventing AI training on premium content while allowing search indexing.

The wild part? Half the users don't even monetize their content - they just want visibility into who's reading their work. Fair enough.

If you're sitting on a content site and haven't set up AI crawl controls yet, you're essentially giving away your IP. Not fearmongering - just data.

Built this at serpspur.com/tool/llms-txt-generator-tool if you want to skip the XML headache. Or just google "llms.txt spec" and DIY. Either way, get it done.
