Hi there!
Like in everything that concerns people (in you case your future readers) there are 2 questions you need to answer first: 1. what makes your blog unique i.e. what will make your blog the preferred blog for your target group?
2. what is your specific target group and what is their unsatisfied need your blog is going to satisfy?

Both go hand in hand, especially concerning blogs as you are the product therefore it's better to find people that will be attracted by your personal offer vs. inventing a different persona (although you could ;).

Let's imagine you have curves and like to dress very smartly. Now, out there there might be a target group (your future audience) who is missing a blogger/fashion expert that explain them how to dress classy when one has curves. Then you have a reason to exist which will transform into getting a followship faster and cheaper than if you are not unique.

Based on that, you will be looking into monetization in a very different way because you will try to partner with companies or bloggers that target the same profile of people.

Similarly you will be selecting a name that is very different from the name you would want to appeal to hard core campers for example.

I am happy to jump in a call to help you transform what is unique in you into a viable blog/business :)

You can also watch my TED talk - it's about marketing applied to online dating, but the same principles I exposed above are treated in the video (plus it's fun ;)
