We’ve enriched the Links endpoint in our On-Page API with deeper insights into multilingual and international SEO setups.
What’s new
This update introduces two new fields — is_valid_hreflang and hreflang — designed to help you audit and validate hreflang configurations directly from your link data.
How it works
When you use the Links endpoint, each link object with "type": "alternate" in the response now automatically includes:
is_valid_hreflang indicates whether the hreflang attribute is correctly implemented.
hreflang displays the actual value found in the link tag (language and optional country code). For example: "en-US", "fr", "de-DE".
Why it matters
This features allows you to:
Automatically audit hreflang attributes across your site.
Identify invalid or misconfigured tags that may impact international SEO.
Ensure that search engines correctly understand your multilingual content targeting.
