In my opinion I think it really depends on what your real target is and what you niche really is.
For example for online casinos it is important to write latest trends on say personalities who have something to do with the casino. Say someone won a lot of money and is also famous or cryptos theses days BTC associated with the online casinos. But perhaps the online casino review websites would get the most conversions for people
If it is something like the FINTECH industry then trading strategies like GBP/JPY strategy and a short post on a FaceBook page would do potentially better for a Financial Trading or Prop Trading or Algo Trading companies
In my opinion
