roast.page combines AI vision analysis, HTML content extraction, and Google PageSpeed data into a single conversion-focused score across 8 weighted dimensions. Most landing page tools analyze only one layer — page speed, SEO metadata, or copy readability — in isolation. The median page scores 44/100 on roast.page, and the largest gaps are in messaging (4.8/10 median) and trust (4.2/10 median) — dimensions that pure technical tools don't evaluate at all.
What makes roast.page different from other landing page tools?
AI vision analysis. Most tools analyze HTML, metadata, or page speed. They never actually look at the page. roast.page captures high-resolution screenshots and feeds them to an AI that evaluates visual hierarchy, layout, and design impact — the same way a human visitor experiences the page in the first 50 milliseconds (Nielsen Norman Group). 83% of top-scoring pages (72+) show the actual product in their hero — a pattern invisible to code-only analysis.
Unified conversion scoring. Instead of a speed score from GTmetrix, an SEO score from Ahrefs, and a "looks good" from a colleague, roast.page combines technical performance, content analysis, and visual evaluation into a single weighted score across 8 dimensions. Technical SEO accounts for 7% of the weighted score because that's its measured impact on conversions. Hero impact and copy account for 40% — because that's where 62% of pages fail.
Where do other tools have genuine advantages?
- SEO crawlers (Screaming Frog, Ahrefs) — Superior for site-wide technical SEO audits. roast.page analyzes one page at a time; crawlers scan entire sites for broken links, redirect chains, and indexation issues across thousands of URLs.
- Heatmap tools (Hotjar, Microsoft Clarity) — Superior for understanding actual user behavior. roast.page's analysis is AI-predictive; heatmaps show what real visitors do. Hotjar tracks 1.3M+ websites (Hotjar, 2025). Use heatmap data to validate roast.page findings.
- A/B testing platforms (VWO, Optimizely) — Superior for validating hypotheses with statistical significance. roast.page identifies what to test; A/B platforms prove it. Companies running systematic A/B tests see 2–3x higher conversion lifts (VWO, 2025).
- Page speed tools (GTmetrix, WebPageTest) — More granular performance diagnostics with waterfall charts and advanced debugging. roast.page includes Core Web Vitals via Google Lighthouse but doesn't provide request-level waterfall analysis.
The highest-ROI workflow combines tools: roast.page for the initial strategic audit (under 60 seconds), a heatmap tool for behavioral validation (1–2 weeks of data), and an A/B testing platform for iterative optimization (ongoing). Each tool serves a different phase of the optimization cycle.
