Unfortunately, this is a loaded questions and boils down to one question.  What are you trying to accomplish with your writing.  As long as it’s informative you should include any amount of information that makes your content relevant.  Research has concluded that the longer your post is the more it tends to attract readers.  Of course, without an in-house writer it can be hard to find the time to actually build long content.  Keeping this in mind, blog posts can be a better option, maybe posting 1-10 times a month depending on how much time you have available, while maybe building one big page/article a month all while promoting your content via the various channels like facebook, quora, reddit, medium, etc.
