Yeah, i make and edit my own video.
Yes, i work in gaming niche, but I'll try in other niches in the future.
I'll tell you how i do it.
1. Search and find a game.
2. Check if the game is country based. Because i will not use a game where they have only pin submits as offer. I know from my country, there is only pin submits and no one will do that.
3. Make a video and upload it as unlisted.
4. While the SMM service is providing youtube views, likes, dislikes, shares, buy domain and make your landing page.
5.Publish the video and after one day insert the link. I leave it as Link: Maintenance.. before putting the link.
