When it comes to choosing the right niche for a new website or a blog you have to know that not all niches are equal.
Some niches simply can drive the same amount of traffic as others, for example, articles talking about legal problems won't have the same potential on getting viral as articles talking about Kim Kardashian.
On this note, I'm going to share a list of top niches:
For some reason, I always thought that Entertainment subjects will be the most popular niche you can choose to write about, apparently is not. Health and Fitness related content have a lot of weight and huge potential.
Although as content writers such general niches may be paid less than let's say, Science-based articles, I'm sure with enough professionalism and the right doze off "uniqueness" you will be able to find the right client out there to sell your writing at the value it deserves.
