🌍 Hreflang Tag Checker – SEO Tool for International Websites
The Hreflang Tag Checker is a powerful SEO utility designed to streamline the process of auditing a website’s hreflang implementation. It extracts all hreflang attributes from a given URL and then crawls each linked language version to verify the existence of a correct return link (rel=“alternate” hreflang).

This ensures that your multilingual or multi-regional site is correctly set up for international SEO and helps search engines serve the right content to the right users in the right language.

✅ Features:
- Parses all hreflang tags on a page
- Crawls target URLs to check for return tags
- Supports hreflang validation for large websites
- Helps identify missing or incorrect hreflang implementations

The Hreflang Tag Checker is designed to automate the process of checking a site’s hreflang tag implementation. The tool extracts a URL’s hreflang tags and then crawls each target URL to verify that they correctly reference back to your current URL.

This saves valuable time when evaluating language targeting and hreflang structure, giving you a quick, reliable overview of a site’s optimization for international organic search.
