Codice di stato 200 (OK)
HTTP Status Code 200 is the standard response for a successful HTTP request. It indicates that the server successfully found the requested resource and sent it back to the client. For SEO, this confirms that a page is live, accessible, and ready to be indexed by search engines.
The Baseline Health Check
A 200 code is the "all clear" signal—the page exists, the server is working, and content is being delivered. This is the baseline expectation for all your translated pages. If your French URLs return 404s or 500s instead of 200s, they won't get indexed, killing your international SEO. Regular monitoring (using tools like Screaming Frog or Google Search Console) ensures all language versions return 200 codes. The only exceptions should be intentional redirects (301/302) or deleted content (404). Any other status code (500 server error, 403 forbidden) means you're losing visibility and traffic.
