If you have exactly the same content on a page with different URLs, one of these pages should be designated as 'canonical', meaning it should contain the tag rеl="canonical". Search engines will take it as a signal that this page should be treated as authoritative and to disregard the duplicate page.
Any website made on Tilda has a service address that looks like this: http://project12345255.tilda.ws
. When you connect your own domain (http://mysite.com
) and publish all pages, your domain will automatically become the main URL (it acquires the rеl="canonical" link). A service address can still be displayed in your browser but search engines will ignore it – unlike the canonical page with your own domain.
You don't need to do anything else.
SEO specialists, this is for you: to edit the canonical URL, go to the page Settings > Facebook and SEO > Search Results > Set Special Meta Data > Link To Canonical URL.
