Well you need to go everywhere where your niche its .Lets say for example your niche and offer its hosting affiliate .Then you would go to quora for example and many people will ask questiins about how to build a website ,how to instal hosting etc ,then you want to give helpful answers and from time to time you recommend your affiliate offer .You can also create a yt channel and blog and create helpful content in your niche and have affiliate links on your blog ,yt video etc .Also create short videos and post them everywhere on tiktok ,pinterest ,yt short ,instagram and fb reels .hope this helps

I think you should start research in quora since quora is very powerfull.

Specific I suggest to you facebook & pinterest. But first of all you research how can possible to reached targeted audience!
