Optimise for AI-driven search with LLM Testing

Why LLM Testing Matters

AI chatbots and search assistants are rapidly becoming a major source of answers - and recommendations. Whether someone’s asking “What’s the best pizza in London?” or “Top SEO tools for agencies”, Large Language Models (LLMs) are starting to influence what people click, buy, and trust.

The LLM optimization challenge?

LLM answers are generated from a mix of sources, and it’s not always obvious how or when your content gets included. Even small changes to your page could affect whether you’re cited, recommended, or completely missed out.

LLM Testing in SEOTesting gives you a way to measure these changes — with hard data from GA4.

From Page Changes to AI Citations - Measured

An LLM Test is a time-based test that lets you measure user sessions generated from LLMs before and after you make a page change.

You decide:

  1. Which page or group of pages to monitor.
  2. What change you’re making — content updates, schema tweaks, adding FAQs, improving internal links, etc.
  3. How long to track before and after the change.

SEOTesting then pulls the data from GA4, showing you how LLM-driven traffic trends over time.

Why This is a Game-Changer

  • No more guesswork – finally track the impact of LLM visibility efforts.
  • Fast, simple setup – connect GA4 and you’re testing in minutes.
  • Fits your workflow – works like other time-based tests in SEOTesting.
  • Data you can trust – straight from your analytics, no scraped estimates.
