Optimising Sitelinks with Rankmath

Hello @eightsages

Thank you for your message.

Those are called Sitelinks and Google decides them on their own.

Google sitelinks aren’t something you can enable, activate, or opt-in for. It’s up to Google to enable them for a website which they think is authoritative for a given query. There is no specific setting or Schema to instruct Google to display links in Sitelinks.

You can read more about that here:

With that said, here’s a nice guide you can follow to increase your chances to have Sitelinks from your website:

Hope that helps.
