Hello Friends,
What is the Cross Domain, how it’s different from domain and sub domain and what’s the use of it and how it is useful in seo ?
Thanks
It isn’t really anything to do with SEO.
Your domain is the main bit of your URL, along with any TLDs, eg domain.com.
A subdomain is on the same domain, but has a prefix in front of the name (technically www. makes a subdomain, but as it is usually the default, it is not treated as such), eg help.domain.com.
Cross-domain refers to when you link to or reference materials and resources on another domain. eg, you might have a funky script that you want to include on all sites you build, and rather than copying it onto each domain and then having to remember to update all of them, you could put a reference from domain.com to preeti.com/script.js - that’s cross-domain.
