Can a person have two successful blogs of different topics?

In the digital media sector, anything is possible if it is legal. One can have as much as long one wants to make the blog successful. If one is a start-up or newcomer in the field, one can initiate the write-up project in his or her favorite niches. This will help one to grow significantly in the favorite niche & ultimately one can also move forward to other niches. Let’s take an example of famous blogger Gary Vaynerchuk. He is a multi-talented blogger who worked in many niches & has also become a successful entrepreneur. He has written about everything from whines to the latest fashion trends & technical application to the ultimate marketing niches. Another example is Amy Lupold Blair the founder of Resourceful Mommy. She has a specialization in writing & blogging about family & products. She also writes about the marketing powerhouse related to the social media platforms. Now one must be thinking what parameters & metrics must be used or how to increase the reach of our blog along with maximum clicks? How one must use social media platforms to promote their precious works. One must also be thinking that one does not only want people to read their blogs but also hoping to turn their blogs into practical use in their businesses. One can also sell service & products through blogging on different social media platforms. These are the ultimate things one can have in their minds while blogging for several niches & platform at the same time.
