Hello @AjeetV ,
Are you referring to a coded form like a pop-up or inline form? Or are you referring to a landing page sign up form?
For information on installing a coded form into your website, I'd recommend following along with this article, which includes instructions for several different web hosts (including notes on ones the coding isn't compatible with).
For information on sharing / copying a landing page sign up form's permanent URL, I'd recommend following along with this article.
