DOI display on landing page only in pop-up

Is it acceptable to have the DOI displayed on the landing page only in a pop-up (accessed by e.g. hover or click), or should it always be displayed in the main text of the page?

Hello @rhiannon-ppl,

We would recommend that the DOI would be displayed clearly on the landing page as best as possible.
Here is our documentation for landing pages but it doesn’t specifically mention the location of the DOI just there should be one displayed. I think if it is hidden behind a pop-up only accessed by hovering over it then it would be not noticeable enough.

Here is more information on Crossref’s DOI display guidelines as well.

I hope this helps,
Paul
