There are bloggers who want to write on everything, almost. There are bloggers who focus on a niche. Both can work and both can fail. It depends on the expertise of the blogger. Not the writing expertise but knowledge. Not every blogger can develop a sound understanding of every subject that can be written about. If you are alone or have a very small team, then it is best to focus on a niche. Trying to write about too many things will not only be bafflingly challenging but it will also confuse your potential audience. Readers like specificity. You too would be perplexed as to whom you wish to target. If you check out the popular blogs or even the video bloggers who have amassed millions with their channels on YouTube, all of them are focusing on a niche that is well sorted.
