How Does the Hreflang Checker Work?
The Hreflang Checker works by real-time crawling any URL you enter and extracting all hreflang tags from the HTML source. It validates language and region codes against ISO standards, detects missing x-default tags, duplicates, and invalid links. Then it uses AI to analyze results and provide instant fixes.
You get a 0-100 score reflecting your hreflang implementation quality, a list of critical issues, quick fixes, and missing languages you should add. You can export results as CSV or JSON.
FAQ
What are hreflang tags?
Hreflang tags tell search engines which language and regional version of a page to show to users. They're essential for international SEO on multilingual websites.
What is x-default?
x-default is a special hreflang value that specifies the default page when no other hreflang tag matches the user's language. It's recommended for every hreflang implementation.
What are return tags?
Each page referenced in a hreflang tag must link back to the original page. Missing return tags can cause hreflang to be ignored by search engines.
