Introducing Filter’s Free LLM AI Search Optimisation Audit

17 March 2026 3 mins read

We’re simplifying GEO/AIO, allowing everyone to identify simple changes to improve visibility across major AI search platforms such as ChatGPT, Gemini and Claude.

A dashboard displaying AI tool performance scores. An overall score of 50/100 is shown on the left, rated as Average. Individual scores listed are ChatGPT 58, Gemini 52, AI Overviews 40, Perplexity 35, Claude 61, and Bing Copilot 56.

What is the LLM AI Optimisation Audit?

More business decisions now start with a question typed into ChatGPT, Gemini or Perplexity than ever before. Buyers research suppliers. Professionals seek recommendations. Decision-makers look for solutions, and increasingly, they’re asking AI tools rather than starting with a Google search.

Our audit checks your URL across six major AI platforms and analyses over 70 ranking factors including meta tags, structured data, semantic HTML, content quality, E-E-A-T signals, image optimisation and internal linking to give you a clear score showing how AI sees your page. The six platforms we assess are:

Each platform processes and evaluates content differently. Some prioritise structured data. Others weight authorship signals or content freshness. A few look closely at how your content is formatted, whether you use lists, tables, or Q&A structures that AI can easily extract and cite.

What You’ll Get

When you run your audit, you’ll receive a detailed report covering several key areas:

An overall AI optimisation score out of 100 that tells you how well-optimised your page is for AI platforms compared to other sites.

A platform-by-platform breakdown with individual scores for ChatGPT, Gemini, AI Overviews, Perplexity, Claude and Bing Copilot.

Key issues affecting your visibility, prioritised by impact, so you can see exactly what’s holding back your score and how much it could improve.

A website audit executive summary showing strengths such as Open Graph tags and HTTPS, alongside areas for improvement including missing article tags, author bio, and publication date. A projected SEO score improvement from 50 to 100 is highlighted.
A detailed SEO audit results dashboard displaying meta tags and structured data metrics. Columns show quality scores ranging from 70% to 100% alongside affected large language models including ChatGPT, Gemini, AIO, Perplexity, Claude, and Bing.

Quick Wins You Can Action

You can start making improvements right away.

Start with the quick wins. Many of the issues flagged in your report are straightforward to fix – adding missing meta tags, improving heading structure, or implementing basic structured data.

Prioritise by impact. Your report ranks issues by priority and shows the potential score gain for each fix. Focus on the high-impact items first. A few targeted improvements can significantly shift your overall score.

Go Deeper

Audit your full site. The free audit analyses one page, which is useful for understanding the general picture. But if you want to see how your entire website performs, then our Full Site LLM Optimisation Audit provides the complete view.

Get expert support. Some improvements require development work: implementing schema markup, restructuring semantic HTML, or building E-E-A-T signals properly. We’re happy to help if you’d like support with implementation, or to discuss the findings.

A recommendations dashboard displaying a prioritised list of SEO and content issues, categorised by priority level (High, Medium), with columns for Category and Issue. Items include structured data, meta tags, content quality, and semantic HTML concerns.
