What does this mean for you? How can you increase the authenticity on your blog? Be as authentic as you can possibly be. You don't need to write an autobiography on your About us page nor do you need to pour your heart and soul out every time you write a new blog post. You should, however, put enough personality and personal anecdotes into your posts so your audience knows you're all in this together.
There are literally millions of blogs on the internet, and only a fraction of them are earning any income. (It’s hard to get exact statistics, but I’d guess that that less than 10% of bloggers ever become “full time”. I heard somewhere that 90% make less than 1$ per day – but don’t worry. I make well over 100$ each and every day, and I will show you WHY I earn money with my blog, so that you can start your own blog and make money too.)
If you’ve gone with a self-hosted WordPress site like I suggested, you’ll have literally thousands of amazing free and paid theme options at your disposal. Plus, once you buy a theme (which are relatively inexpensive investments) like the one I use for my blog here, OptimizePress, you'll own it forever and get all the benefits of excellent support and customization options that come with premium WordPress themes.
