Frequently Asked Questions
What does the Hreflang Checker actually test?
It fetches your URL, reads hreflang annotations in the HTML head, and checks for missing return tags, invalid language or region codes, missing x-default, and self-reference errors, then lists recommendations for each problem it finds.
Why do hreflang return tags matter so much?
Google treats hreflang as a two-way agreement. If page A links to page B but B does not link back, the pair is ignored and the wrong language version can rank. Return tag errors are the most common hreflang issue and the checker flags every one.
Is the Hreflang Checker free to use?
Yes. Create a free Brainito account and you can run unlimited hreflang checks, along with the rest of the Brainito SEO toolkit. No credit card is needed, and results appear in seconds so you can retest right after you ship a fix.
