There are literally thousands of kids and teens making great money on Youtube. You can too. You can do product reviews, challenges, eSports, or even vlogging. It is a lot of work but if you will stick to it you can make it a career. EvanTubeHD makes over $1.6 million a year and he’s just a kid! If you are not camera shy then join the ranks of other successful kid Youtubers. I recommend the Hollens Creator Academy for getting started.
Again, if your blog has a large reader base, then businesses may be interested in paying you to review their services or products. Not only will you get a free trial using whatever these businesses are selling, you will also get a fee for writing them a review and posting it to your site. Paid reviews (and other paid and sponsored content) can be big money, so advertise this service on your contact page to generate business.
