Content & AI Enrichment
Strips HTML tags, scripts, and styles — produces a clean text representation of the page.
Basic content length metric for the analysed page.
Automatic extraction from URL paths, H1, title, meta, breadcrumbs, category tree, headings. Scoring: weight x log2(frequency + 1) x log2(product_count + 2).
Assigns keywords to categories (product, service, location, brand).
BGE-M3 model via OpenRouter — 1024-dim vectors stored in pgvector for semantic comparison.
Cosine similarity search across the embedding database — finds websites with similar content.
Tech Stack Modernity
Evaluates how modern the detected technologies are and the adoption of best practices. Output: tier (Legacy / Standard / Modern / Cutting-edge) + score 0-100. Composed of two equally weighted categories (50/50):
Total score calculation
Modernity Score = Tech Stack (50%) + Best Practices (50%)Each category is normalized to 0-100 and the result is their average.
Tech Stack (50% of total score)
The best detected technology is counted for each category. Max raw points: 43 (normalized to 0-100).
Best Practices (50% of total score)
Points for implementing modern web practices. Penalties for outdated HTML patterns.
