Generally speaking, ymyl covers personal finance or medical-related issues.
Google has been broadening the coverage of ymyl slowly over the years.
Still, if you're talking about case studies and social media growth I suppose that this still falls outside of ymyl.
How long it will stay outside the reach of ymyl is anybody's guess.
On the other hand, if you're talking about CPA programs and under affiliate topics this might still be on the borderline, but if you focus more on what people stand to make instead of actual case studies and how-tos, you might be roiling the dice there.
That type of content is more likely to fall within the coverage of ymyl.
