Most of the people watch preview before the video so making a short video with the full video link in it would actually help people to make less effort to find the video.
Posting the best part of the video as short content would really help the new channels to grow and save huge amount of time for the viewers. People mostly watch a sex scene on some other platform and try to find the video the website. So, posting such 30-60 seconds videos on this site would make people to stay on site and keep scrolling till the find best video.
