What's better for a blog post, to be long or short?

Your main focus should be covering the topic in such a way that your readers can take away useful information after they read it.Google is now preferring in-depth content to shorter ones. But as long as your content has quality length should not be an issue. The reason I say so, is because there are sites which have tips and tricks sites which cover awesome topics which are sometimes long or short.

mmmm many prefer short topic , but i see that short topic not useful in all cases ... So that let's your topic develop itself and don't obstruct it until you get the whole meaning .
