Beyond Speed Tests
Every tool measures page speed. PageDiag tells you what actually drives revenue for ecommerce.
AI Shopping Score
ChatGPT, Gemini, and Perplexity are already recommending products to millions of shoppers. If your store isn't optimised for them, you're invisible to a growing chunk of buyers. PageDiag scores how ready your product pages are for AI-powered shopping and tells you exactly what to fix.
No other tool measures this.
LLM Visibility Score
AI search is replacing Google for millions of users. Your structured data, content clarity, and technical setup determine whether AI models can understand and recommend your site. We check your llms.txt file, schema markup, and content structure.
The SEO frontier no one else is testing.
Widget Health Check
That review widget or chat bubble could be costing you more sales than it generates. PageDiag detects every third-party integration, measures the exact load time hit, flags conflicts and duplicates, and suggests lighter alternatives.
Know exactly what each widget costs you in speed.
Review Compliance Checker
The CMA and FTC are cracking down on fake and misleading reviews. Gating negative reviews, incentivising without disclosure, only showing 5-star ratings? That's a fine waiting to happen. PageDiag scans your review setup and flags compliance issues before regulators do.
Stay compliant before it becomes a problem.
