LLM SEO: What It Means and How to Start

LLM SEO is the practice of getting your content referenced by large language models and their associated crawlers. It is search optimization for a world where the search results page is no longer the only door. When someone asks ChatGPT a question and your business gets mentioned, that mention came from somewhere. LLM SEO is how you improve the odds that the mention is you.

Why LLM SEO matters now

Google still sends traffic. Most small businesses should keep their SEO basics intact. But the discovery path has split. People now ask AI assistants directly, and those assistants pull answers from the web in real time.

That pull is not random. It is driven by crawlers, the same way Googlebot decides what appears in search results. The difference is that AI crawlers have different rules, different priorities, and different user agents. They are bots, so they are trackable. You just need to know what you are looking at.

That is where the practical work begins.

The three kinds of AI crawlers

Not all AI traffic is the same. Kymo classifies AI crawlers into three categories, and the distinction matters because each one behaves differently.

The table below shows the clearest breakdown.

You need to know which one is hitting your site. Blocking all AI crawlers with your firewall might stop training bots, but it also stops ChatGPT-User. That is the bot that can send you a human visitor who is literally asking about your product.

What actually counts as AI traffic

Here is the confusing part. AI crawler hits are not human traffic. They are bots. Most analytics tools either ignore them or mislabel them as suspicious or unknown. A tool like Kymo treats them as their own category, separate from human pageviews.

This does not count against your event limit. You can track a million crawler requests and it will not eat into your monthly allowance. That is intentional. AI visibility is a signal you need, not a penalty you should pay for.

Kymo also keeps the crawler's user agent on the crawler's own event row, so a classification can be checked against the string it came from rather than taken on trust. A crawler is not a person, which is why that string can be stored at all. No human visitor's user agent is ever stored.

How to start with LLM SEO

You do not need to rebuild your site. You do not need a dedicated "AI content" strategy that ignores your human readers. You need visibility.

Start with a free AI visibility check. It reads a URL from public signals only, so the site does not need Kymo installed. The report arrives by magic link over email. That gives you a baseline without touching your code.

Then install analytics that can see AI crawlers. If you use Kymo, the dashboard shows you which pages AI assistants fetch, the likely prompts behind those fetches, and confirmed click-throughs from AI referrals.

What to look for in your data

First, check which pages get crawled by indexing bots like Claude-SearchBot (Anthropic's search index crawler). If the crawler is visiting, it is interested. If it visits and then you never see a click-through from an AI referral, the content likely does not match the query intent.

Second, watch for ChatGPT-User (OpenAI's live fetcher). This is the bot that appears when someone is in a real ChatGPT conversation and the assistant decides your page is worth checking live. A high number of these means your content is being pulled into active answers.

Third, look at the GPTBot (OpenAI's training crawler) traffic. Training crawls are bulk and infrequent. If you see a spike, your site was flagged for a training run. It does not mean you got a customer. It means your content is in the dataset.

The difference between analytics and action

LLM SEO is not a set-and-forget tactic. It is a measurement loop. You see an AI crawler hit your page, you check what question it was answering, and you decide if the answer your page provides is good enough.

The loop is short. A crawler reads a page, you check what question it was likely answering, and you decide whether the page answers it well enough to be quoted. Nothing about that promises a ranking. It only tells you where you stand.

Privacy and AI tracking

You do not need to violate privacy laws to track AI crawlers. A crawler is not a person. Kymo's visitor counting is cookieless. No cookies, no localStorage for tracking. The visitor identifier is a salted server-side hash that rotates at UTC midnight, so "unique visitors" means unique per day. Raw IPs are never stored, and no human visitor's user-agent string is ever stored.

The AI crawler user agent is kept on the crawler's own event row so classification stays auditable. That is different from human tracking. If the topic interests you, the post on Privacy-First Analytics: What It Actually Means covers the distinction in more depth.

The gap in your current setup

Most small business analytics are blind to AI traffic. GA4 will show you session duration and bounce rate for humans. It will not tell you that PerplexityBot hit your pricing page 40 times in one morning.

Without that data, you are guessing. You might write content aimed at ranking on Google for "best project management tool" while ChatGPT is answering that query using your competitor's comparison page.

How to See AI Traffic in Your Analytics shows exactly what you are missing and how to fix it.

Practical first steps, in order

Check your robots.txt. If your file is blocking GPTBot or ClaudeBot, you are cutting off a source of discovery. Most sites can safely allow indexing bots. If you are unsure, the robots.txt for AI Crawlers: A Copy-Paste Guide gives you working examples.

Then run the free visibility check on your homepage and your two best product pages. Compare the results. If the check finds you in some AI answers but not others, that tells you where the gap is.

Then install Kymo or equivalent so you can see ongoing crawler behavior. Watch for patterns over a week. Which assistant fetches you most? Which pages draw the indexing bots?

A quick word on the limitations

None of this guarantees a top placement in ChatGPT. Crawler tracking tells you what happened, not what will happen. A bot visit does not mean a citation. A citation does not mean a click. But zero bot visits means your content is not in the running at all.

LLM SEO is a visibility game. You can only improve what you measure.

Use the data, then improve the content

Once you know which pages attract AI crawlers, make those pages better at answering questions. Put the answer in the first paragraph. Use clear headings. Write at a reading level an eighth grader can handle, because the AI has to summarize you in a few sentences.

The boring truth is that clear, factual content works for both human readers and AI assistants. You do not need a separate content stream. You need to know which of your existing pages AI trusts, and then double down on those.

Start tracking, or work through the guide

If you want a structured approach to making your content more answerable, work through The Small Business Guide to AEO. If you want to know whether any of it is working, start tracking it, there is no other way to find out. You also get a free AI visibility check that reads a URL from public signals, so the site does not need Kymo installed, and the report arrives by email.
