Y’a pas de quoi: technical SEO, in English

Test whether your URLs are allowed or blocked by a robots.txt, for Googlebot and AI bots.

Generate a clean robots.txt and control AI crawler access (GPTBot, Google-Extended, etc.).

Recursively extract all URLs from an XML sitemap, audit hreflang and duplicates, export to CSV.

Audit the reciprocity and compliance of your hreflang: return tags, BCP-47 codes, x-default, self-reference.

Analyze a list of 301 redirects: chains, loops and self-redirects, with suggested flattening.

Audit your .htaccess: simulate Apache, spot obsolete rules, catch-all and invalid regex.

Follow redirects and read the headers (indexing, cache, compression, security), with TTFB before/after cache.

Analyze any page's JSON-LD, spot missing types and generate corrected markup.

Import a list of URLs and qualify them by paths and patterns: groupings by directory, regex categories and charts.

Extract a page's entities (Wikipedia/DBpedia), their types, importance and relations.
