freebie question

I just created my freebie, and when people sign up on my website, they get an email with a link to the freebie. Right now, I have the link take them to a pdf. Is that ok? Or should it go to a page on my website? I previously asked about lead pages – whether there’s a benefit to having it go to a lead page or just to a page on my website, or whether a pdf is fine
Would love your help with this!
