new genres?

So I have thought I would always just stick with cozy mysteries= it is what I know and love, but since getting my Kindle I have really opened my eyes to new genres- I still love my cozies but I am now reading everything from Cozy, YA, Paranormal, Chick Lit, erotica etc- so I want this blog to be more well rounded.
I wanted to take more time and focus on my blog more- I am at a place now with work and life that I think it can be done-
Look for reviews, and I hope to have a weekly giveaway- I will be putting together a giveaway for new followers- maybe an Amazon gc?? I am thinking about what to do- and how to get more followers- I have read some great blogs and have tried to take what I like from each one to make a great blog
