How Do I Know If AI Is Citing My Website?

Most business owners find out their site isn't in AI search by accident. Here are four ways to check.

1. Query ChatGPT and Perplexity directly

Search for your brand name, your core service, and the main questions your customers ask.

Ask prompts like:

"What is [your business name]?"
"Who are the best [your service] providers in [your city]?"
"Which websites are most helpful for [your topic]?"

If your site is in the training data or retrieval index, you should see it mentioned or linked. If you never see your brand or domain, that’s a strong signal you’re not being surfaced.

2. Search Google for your target queries and watch for AI Overviews

Google’s AI Overviews appear on some searches at the top of the results.

Steps:

Google your main money keywords (the ones you want to rank for).
When an AI Overview appears, expand it fully.
Look at the cited sources under the answer.

If your site isn’t among those citations for queries you care about, you’re not yet in the AI Overview rotation for those topics.

3. Run a structured data audit

AI engines heavily favor content that’s easy to parse.

Check that your key pages use:

FAQPage schema for Q&A sections
HowTo schema for step‑by‑step guides
Article / BlogPosting schema for content pieces
Clean H1–H3 heading hierarchies

Use Google’s Rich Results Test to validate your pages. Missing or broken structured data is one of the most common reasons AI systems skip over otherwise good content.

4. Check for an llms.txt file

Place an llms.txt file at the root of your domain: https://yourdomain.com/llms.txt.

This file:

Acts like a robots.txt for AI systems
Gives AI crawlers a curated map of your most important URLs
Lets you highlight canonical, up‑to‑date resources

If it doesn’t exist, you’re missing a direct, machine‑readable signal that many AI systems are starting to look for.

This isn’t a one‑time check

AI search visibility changes as models retrain and indexes refresh. You’ll need to:

Re‑run these checks quarterly (or after major AI updates)
Monitor which pages get cited and which don’t
Continuously refine structure, schema, and internal linking

The durable solution is designing your content architecture for AI from day one, not patching on schema and files after the fact.
