AI SEO and llms.txt: Why This Matters Right Now

If you've been working in SEO or digital marketing for a while, you've probably noticed how quickly things are shifting. Google updates used to be the big worry. Now? It's AI search engines like Perplexity or even when someone asks ChatGPT about your brand. The search volume for AI-related queries has exploded, and your target audience is increasingly turning to these platforms for high quality information.

The tricky part is that these systems don't crawl the web like Google does. They need a little help. That's where llms.txt comes in — it's a simple file, but it can guide AI systems on how to use your content. This creates an AI overview of your site that helps these systems understand your content better.

Why Add Another File?

I'll be honest: the first time I heard about llms.txt, I thought, “Great, another SEO thing to keep track of.” But after digging in, it started making sense.

Perplexity AI pulls answers directly from sources. If your site has an llms.txt file, you have a better shot at being one of those sources.
Developers I know have tested it with Anthropic's Claude and noticed the model "respects" those signals more than raw scraping.
A mid-sized SaaS company we checked saw a 15% bump in organic traffic from AI search mentions after adding llms.txt.

It's not magic, and it won't replace your usual SEO strategy like link building or keyword research. But it fills a gap that old tools like robots.txt just weren't built for. Plus, it helps your content reach your target audience through social media sharing and AI-powered discovery.

How It Fits Into Real SEO Workflows

If you're already managing Google Search Console, publishing content, or optimizing pages, adding llms.txt is a low-lift task.

Think of it like this:
SEO optimization → tells Google what to index.
llms.txt optimization → tells AI what’s safe and useful to learn from.

The nice thing is, it also saves time. Instead of answering the same “Can AI use my site?” question in endless ways, you set the rules once.

A Quick Tangent on Content Creation

One interesting side effect: I’ve seen writers and creators start using their own llms.txt files almost like a portfolio. Instead of just hoping AI systems cite them, they’re structuring their best content to be “AI-ready.”

It reminds me a bit of when sitemaps first started gaining traction — at first, only the technical folks cared. Then marketers realized it gave them more control. I think llms.txt is on that same path.

Getting Started Without Overthinking It

Create a plain text file named llms.txt.
Add a few clear lines about what AI can or can’t use.
Upload it to your site’s root directory (just like robots.txt).

That’s it. No special tool required — though there are free generators if you’d rather not hand-write it.

Will it solve every AI SEO challenge? Probably not. But it’s one of those small, forward-looking moves that could pay off, especially as AI-driven search keeps growing.

Next Step

If you already have llms.txt set up, consider submitting your site to our directory. And if not, maybe block 15 minutes this week to try it out. Worst case, you’ll learn something new. Best case, you’ll get your content positioned for the future of search engine optimization.
