What Is AI Visibility Score and Why It Matters for SEO in 2026

Search engines are no longer the only way people find information online. In 2026, AI assistants like ChatGPT, Claude, Perplexity, and Gemini are answering millions of questions daily — and recommending websites in the process.

But here's the problem: most website owners have no idea if their site is visible to AI assistants. You can check your Google rankings with any SEO tool, but until now, there was no way to measure your AI visibility.

What is AI Visibility Score?

AI Visibility Score is a metric (0-100) that measures how likely AI assistants are to mention or recommend your website when users ask relevant questions. SiteGlint is the first tool to offer this metric.

The score is based on several factors:

• Brand recognition — Does the AI know about your brand?
• Content authority — Does your site have comprehensive, well-structured content?
• Domain authority — How trusted is your domain?
• Structured data — Do you have schema.org markup and llms.txt?

Why Does AI Visibility Matter?

Here's what we've observed: users who arrive at a website through AI recommendations convert at significantly higher rates than organic search traffic. Why? Because the AI has already pre-qualified them — it has recommended your site specifically for their needs.

This means a website with 100 visitors from AI referrals might generate more revenue than one with 1,000 visitors from Google.

How to Improve Your AI Visibility Score

1. Add an llms.txt file — This is like robots.txt but for AI crawlers. It tells AI assistants what your site is about.
2. Create comprehensive content — AI assistants prefer citing authoritative, in-depth sources.
3. Use schema.org markup — Structured data helps AI understand your content.
4. Build topical authority — Focus on being the best resource in your niche.
5. Get mentioned in sources AI trusts — Industry directories, review sites, and comparison articles.
