When choosing a niche to write your blog about, you definitely want to be passionate about it, or at least like it.

You are going to be learning EVERYTHING about it.

You are going to become an expert.

If it doesn't interest you enough to read about it every day, you will not want to write about it every day. Period.

That's not all, though.

Take a few minutes on each keyword before you pull the trigger. Find 30 keywords that all have over 100 Avg and below 100 QSR. Make sure they make grammatical sense. This is in the certification training for a reason.

It doesn't stop there, either.

Head over to Facebook or Pinterest. Read their Ad Policies. Read the rules for a few affiliate programs that interest you. If anything to do with your niche goes against their policies, it will restrict you later on.

Don't waste time on a niche that is going to be difficult to promote.
