Pourquoi utiliser cet outil ?
On-page SEO issues (a missing title, a duplicated H1, images without alt text...) are easy to miss by eye. This tool analyzes the HTML source you paste directly in your browser and scores it against common on-page SEO best practices. No URL, no server call: paste the HTML you get from "View Source" or your browser's DevTools, and everything runs locally.
