Blogs have become an important factor of link building. Many SEO experts and bloggers choose to manage multiple blogs and also keep them up to date with quality content. Many bloggers single blogs at a time. With one blog you can maintain both quality and quantity of content. An expert is one who is able to keep up the quality and quantity while managing multiple blogs. While maintaining multiple blogs you should keep in mind that your content should be original, your blogs should be up to date and you should be able to allot time for each blog.
No Plagiarism
Those maintaining single blogs have original content but blogger with multiple related blogs find it difficult to keep their content original. If you have duplicate content in all your blogs then visitors would not be interested in visiting your blogs and they would feel as if you are using copied content. If the traffic suspects plagiarism they would not come back to your blog. It may also happen that you wish to steal content from a space that is famous and gets a good traffic. You may not copy it but reader or followers of the space would know that your content is not original. If yours is a new blog then you would like to grip your readers and not want them to go away because content is not original.
Fresh content
Bloggers should post frequently and keep their blogs updated. If content not updated then readers stop visiting the blog. You should never let your blog look stagnant or clumsy to your readers. Even a single reader should be considered precious. If your readers do not find updated content then they stop coming to your space. Internet updates are very fast and if your blog is not updated then traffic would not want to stop by to read. Hence, if you wish to hold traffic to your site then you must keep adding fresh content
Time management
If you maintain multiple blogs you may find it difficult to update all your blogs with multiple posts. As a blogger you should be able to manage time and dedicate equal or sufficient time to all your blogs. I say sufficient time because some need more time for maintenance than others. Once you know how much time is required to maintain all your blogs then it becomes simple by just following a schedule.
Therefore in the end I would only suggest you to manage content very delicately. The moment you stop taking care, traffic stops visiting your blog.
