## Why it matters

Keywords define the thematic focus of a website and are the foundation for both SEO and AI visibility. Automatic extraction reveals what topics a site actually focuses on: often different from what the owner believes.

## In practice

An electronics e-shop has the strongest keywords 'mobile phone', 'notebook', 'tablet'. However, if 'sale' appears as the strongest word in the extraction, the site communicates discounts rather than products.

## How be1st checks it

Automatic keyword extraction from URL paths, H1, title, meta description, breadcrumbs, category tree, and headings. Scoring: weight x log2(frequency + 1) x log2(product_count + 2).
