How should we link to Zoho registration from third party sites who won't accept a button?

We plan to promote a whitepaper from third-party sites. We would like to capture registration information about anyone who requests the paper from one of these sites.  We have set up a button (called something like “I want to read the whitepaper”) for our own site. Some third party sites won't accepts a button for a link. 


Q. Do these third-party sites need to use a  Zoho button, or can we send folks from these sites to our Zoho-controlled registration page via something that just looks like a hypertext link?
