When you are participating in a community forum or board. Then which strategy of content marketing gets your more leads? Articles that provide in-depth information like tutorials & how-to's or straight to the point comments that resolves any problem instantly.
There isn't any competition between them and also I will say that it can't be said for sure that which one is better. The problem solving comments that might not help a lot of users but it can build authority which will generate leads eventually in a long term basis. And, the in-depth articles which helps a ton of users at a time can also generate leads in a short time.
I don't see the point of this thread. As long as any article or post serves the purpose which it is meant to do and gets the job done, the type is irrelevant.
