What’s Your AI Search Visibility Score? Why Traditional Rankings are Lying to You.

"We're #1 for our most important keyword!" That used to be a reason to celebrate. In 2026, it's often a distraction from a much scarier truth.

As Generative AI takes over the search box, the "Blue Links" are being pushed into oblivion. If ChatGPT answers the user's question and mentions your competitor in the first sentence, it doesn't matter if you're the first link below it. You've already lost the lead.

The Share of Model Concept

At SiteGEO, we focus on a new metric: **Share of Model (SoM)**. This is the new gold standard for digital marketing. It measures how often an AI chooses *you* to ground its answer. If you have a 10% SoM, you are essentially invisible to 90% of your potential AI-driven audience.

Why Traditional SEO Rankings Lie

Traditional SEO metrics like 'Domain Authority' or 'Monthly Traffic' are backward-looking. AI visibility is forward-looking. A site can have millions of visitors and still have a **Zero AI Visibility Score** if its content is generic, blocked by robots.txt, or lacks the semantic density for an LLM to cite.

How to Calculate Your Score

You can't calculate this with a simple keyword tool. You need to probe the engines. Ask ChatGPT, "Who are the top 3 agencies for X?", or "What is the best product for Y?". If you aren't in the reply, your score is effectively zero.
