There is a lot of amazing advice on STM.
Some of them are tactical, others are strategic, and a few are truly overarching.
This would fall in the overarching category.
IF YOU ARE NOT DOING THIS ALREADY, LEARN AS SOON AS POSSIBLE HOW TO ADVERTISE ON MOBILE-FIRST, SHORT-FORM VIDEO
Yes this mean Tiktok, as well as all the Tiktok variants (e.g Reels).
The rise of mobile-first, short-form video as a format represents a truly massive, tectonic shift in the media landscape, and this requires A LOT of different skills than traditional online advertising and affiliate marketing. Tiktok's advertising tools will only get better and better, and their audience will continue to grow massively without pause.
In AM, the early bird gets the worm.
Skills like learning how to make short form high converting videos and advertising on these channels are still relatively rare, and this means you have an advantage if you get in early.
I have seen this script play out many times before, the early bird to Google PPC made bucketfuls of money, as did the early birds to FB, to Native, to Mobile, etc etc.
The time to start is NOW.
Each day you delay, it WILL get more competitive, so get started.
NOW
Awesome advice, gonna try it and see how this works out! 
Thanks for sharing this advice, to be honest, I didn't really see that others have written about this recently, and it's something that we definitely need to take into consideration. It's not so difficult to conclude that short forms of videos are taking the throne as they appear now on so many different platforms. Something that once just started on TikTok now has expanded on Instagram with reels and even on YouTube with their new short videos format. So, knowing how to advertise for these short videos and on mobile devices primarily is indeed a skill that can be very useful in the upcoming period. Targeting the right audience that uses mobile phones requires some deeper analyses and research and here we also have to optimize ads to the specifications of mobile devices and also to find a way to quickly engage users since here their attention span is even lower than on desktop.
