Open the toolHreflang generator & validator

Why free
Small, exact tools beat vague scores.
Each tool answers one question properly, shows how it reached the answer and links to the rule it applied. When you want the whole site checked, our free SEO audit covers these and more than a hundred other checks.
Nothing leaves your browser
No uploads, no accounts and no storage. Close the tab and it’s gone.
Built from the documentation
Rules come from Google, the RFC and each crawler’s operator, with the date we last checked them.
Measured, not guessed
The SERP preview uses widths measured on Google’s own results pages, and the robots.txt matcher is tested against the spec’s examples.
English and Turkish
Every tool works in both languages and handles Turkish letters properly.
