track my landing page without campaing

Hi!
I want to track my suscription landing page.
I have not offer to the landing
I have not campaing.

Just my landing page to ppl suscribe to receive other offers.
When the ppl input name and email, redirect to my main site (a blog, not offer, not campaing).

There is any way to track these landing page?
I try to use CTA click url but the button have not space to this field.
Just to send the ppl to my Autoresponder.

Help me please!
