How I Reduced AI Bot Traffic and Improved Site Performance Using LLM.txt

I learned an interesting lesson about AI crawlers this month.

I run a small SaaS that depends heavily on organic traffic. After noticing some long-tail rankings slipping, I dug into my server logs and found AI crawlers hitting the site almost continuously. Besides consuming bandwidth, the extra requests were increasing page response times during busy periods.

I started reading about LLM.txt, which works similarly to robots.txt but is designed to provide guidance for AI crawlers. After creating one and setting rules for the models I wanted to manage, my server load dropped noticeably and overall performance became much more stable.

I'm still monitoring the long-term SEO impact, but it made me realize that AI crawler management is becoming another part of technical SEO that site owners should understand.

Has anyone else started using LLM.txt or monitoring AI crawler traffic? I'd be interested to hear what changes you've noticed.
