Hi,
What you're asking for isn't possible. Anyone on here who currently tells you it is...is misinformed.
Two years ago it was possible to do what you're asking for but then Youtube changed its way of recommending videos. No one can now guarantee that your videos will be 100% suggested at the end of your own video. I know...it sucks and most creators hate that - including myself.
I'm Paul and run the youtube channel Don't Turn Around, which just reached 250,000 subscribers. I'm not only a youtube content creator but a consultant. I've created 10+ videos with 1 million+ views and 50+ videos with 100,000+ views.
There are currently two known ways to push Youtube into recommending your videos next. The first is to have constant keywords on all your videos, the second is using your info card and end screen displaying the same video. But again, there is no longer any guarantee.
If you'd like a consultation or channel review to optimize your channel, let me know.
Best,
Paul
