Website Audit Reports

These reports exist to answer a simple question: how well do websites in your industry actually perform? Not in theory. Not based on guesses. Based on real data from real scans.

We built a scanner that checks every page against four quality dimensions. It reads the HTML. It checks the structure. It scores what it finds. This is the four-part version of the AISO Score. A live audit adds a fifth part, fact-check, which needs a claim-by-claim check that a scan of this size cannot run. Accessibility is scored separately and was not part of this scan.

According to W3C, web accessibility is essential for people with disabilities. Our data shows that AI readiness (AEO) is the lowest-scoring dimension in 109 of the 113 industries scanned. Accessibility was not measured in this scan. According to Google, structured content helps search engines understand your pages. Most business websites still lack basic schema markup and proper heading structure.

What is an AISO Score?

The AISO Score is a website quality metric. It was developed by AISO Studio. It rates any website on a 0 to 100 scale. A higher score means better quality.

The score comes from four dimensions. Each one measures a different part of your site. They are weighted and combined into one number. This makes it easy to compare sites.

1. AEO — AI Engine Optimization (30%) — how well content answers questions for ChatGPT, Perplexity, and Google AI Overview
2. SEO (20%) — meta tags, schema markup, heading structure, and links
3. Readability (25%) — Flesch score, sentence length, and plain language
4. Engagement (25%) — formatting, lists, headings, bold text, and visual structure

A score of 80 or above earns an A grade. Scores from 60 to 79 earn a B. A C is 50 to 59. A D is 40 to 49. Anything below 40 is an F. Most business websites score in the D or F range.

“The average business website scores 58 out of 100. Half of all sites scanned earn a D or F grade, and the average AI-readiness (AEO) score is 39.”

This is not a minor issue. A low score means search engines struggle to understand your content. It means AI answer engines skip your site when generating responses. It means users with disabilities cannot access your pages.

“Government and Agriculture websites scored among the lowest across all industries. These are sectors where public access matters most — yet their sites are the hardest to use.”

The good news is that every dimension is fixable. Adding proper headings, alt text, and structured data can raise a score by 20 points. Rewriting content in plain, short sentences improves readability overnight. These are not expensive changes. They just require attention.

Key Takeaways

After scanning 34,791 websites, several patterns stand out. These findings apply to nearly every industry in our dataset.

• 1.AI readiness is the weakest link. AEO scores are the lowest dimension in most verticals. Adding FAQ schema and direct-answer content would make a huge difference.
• 2.AI readiness is almost nonexistent. Most sites lack the structured content that AI engines need to generate answers. AEO scores below 30 are common.
• 3.SEO basics are often missing. Many sites lack meta descriptions, schema markup, or proper heading hierarchy. These are simple, high-impact fixes.
• 4.Readability suffers from jargon. Long sentences and complex words hurt readability scores. Writing at a 6th-grade level is not dumbing down — it is making content accessible.
• 5.Top performers share common traits. The highest-scoring sites use short paragraphs, clear headings, FAQ sections, and proper semantic HTML.

“The gap between the best and worst websites in the same industry can be 40 points or more. Your competitors may already be fixing this.”
