First, we need to get specific.
What do you want to promote, exactly, on your profile?
I can tell you this, if it's not visual (e.g., makeup, fitness, illustrations, the written word), then it's a COMPLETELY different strategy than everyone else.
Let's say that you want to promote your coding skills.
I would post jokes about coding, that only other coders would get.
I would post code that you think would be useful to the community.
You could do a 60-sec screen record of you creating a code to solve a problem.
You could answer coder questions on IGTV. Create a teaser video to it in your profile.
Get me?
Hope this helps and it's somewhat in the right wheelhouse of the example you needed.
Cheers!
