Doubt about promoting CPA offers on my reddit profile

I have this doubt about it, since I have read that I have to do it using a landing page and in that page is where I am going to put the cpa offers so I can put it in my profile on reddit. That's my 1st question.

2. Can i use google pre landings maker? or programs such as linktree, beacon, snipfeed?

3. Should I put the link of the landing page in my profile on socials section or can I make a pinned post in my profile with the link to my landing page? <- for this i've read that reddit can flagged or shadowbanned your acct if you use a suspicious sites when posting the link in your profile.

I hope I have made myself clear with the questions.

Linktree, Beacon, and Snipfeed work but can get flagged, so a custom domain with a simple pre-lander is a safer bet.

Ok. google ladings maker would be ok? Once that is done, can I make a pinned post on my profile with the domain?
