Deloitte × Google measured +8.4% conversions for retail from 0.1 s, so this is conservative. Your real report uses your own visitors and orders.

AI insights

An analyst that watches every page

The AI reads speed, traffic, search, ads and sales together, spots the patterns a dashboard hides, and tells you what to do next, in plain language and in dollars.

Why did revenue drop last week?

Thinking

Or ask from the AI assistant you already use

An MCP server will let Claude, ChatGPT, Cursor or any MCP client read your speed, sales and search data, read-only.

FAQ

Everything founders ask before installing

Talk to a person

Nothing here is a chatbot. Write to us and a founder answers, usually the same day.

Write to us
What do you need from me for the report?
Your site and a sales export from the last 90 days, from Shopify, WooCommerce, Stripe or your store admin. Access to Google Analytics helps but isn’t required. We delete your exports once the report is delivered.
What if the report doesn’t find anything worth $99?
You get your money back. If the report doesn’t find at least one fix worth more than its price, we refund it in full.
Will the tracker slow my site down?
No. It’s under 2 KB, loads asynchronously and sets no cookies.
Does it work for courses, SaaS and digital products?
Yes. Anything sold online has pages that load and sales that close. The tracker works on any site, and revenue comes from your store or payment platform.
Which platforms do you support?
Shopify today. Stripe is in early access and WooCommerce is next, with PrestaShop, VTEX and Magento on the roadmap. The tracker works on any site where you control the code. Tell us what you use.
Does page speed really affect SEO?
Core Web Vitals are one of Google’s page experience signals: a real but light ranking factor. The bigger effect is on people: slow pages lose visitors before they read. With Search Console connected, you see both on the same page.
How does the AI work?
It reads your speed, traffic, search, ads and sales data together, looks for changes and patterns, and writes each finding with its estimated impact. You can ask it questions in plain language, and it only uses your own data.
Can I use it from Claude, ChatGPT or Cursor?
That’s the plan for 2027. An MCP server will let any MCP-compatible assistant read your speed, sales and search data, with read-only access to the sites you choose.
Is it GDPR compliant?
The tracker is cookie-free and collects no personal data, so it’s built to work under GDPR without a consent banner.
How is this different from PageSpeed Insights?
PageSpeed gives you a lab score for one moment. SIUX Studio tracks real visitors over time and ties each page’s speed to the revenue it makes.
When can I use it?
You can request a revenue report now. The tracker and dashboard open in early access next, and report customers get in first, with the $99 credited to Pro.
