WordPress also have a variety of plugins that make it easy to put social sharing buttons on your blog posts. Some people like to limit the number of plugins they use on their WordPress blog because it can slow the blog down and it can open your blog up to more attacks, butt a social sharing plugin is one that should have high priority if you do choose to use plugins.
I will quibble on one point though, your comment about BBT getting 13,000 subscribers before launching even though you “had nothing but a coming soon page and an invitation to join our email list.” As I recall, you also had a freakin’ awesome video on that page as well that just made people yearn to give you their email address, even without knowing a thing about BBT. So that didn’t hurt, either. ; )
If you’re passionate about something, it will show in your content. Readers will be able to see your genuineness and will be attracted to that. This is probably the most important thing you will learn about blogging. You can try everything in the world and use every tool known to man to be successful, but if you’re not genuine, people will see right through it.
Create and customize your blog. If you are using a free service, there should be a tutorial to guide you through the initial steps of setting up your blog, as well as a forum for people to ask questions. If you are hosting your own site, you will need someone with web design experience to customize your blog, or you can use software such as WordPress.org to use the same structures available at free services.
Oh yeah, I also do all of the above for articles that I write for other blogs. So, if I'm guest posting on a blog, I tend to share it even more than I do my own content. If you guest post on a person's website, you should do the same – the more you share it, the more traffic that person will then get, and the more likely they are to re-share it too.
If you want to really make money with your blog, you need to create a mailing list using one of the billions of email service providers out there. I use and love ConvertKit, but if you are just getting started and don’t understand sales funnels, sequences, or tagging you might want to start off with something simpler and free. If that is the case go with MailChimp where you get the first 2,000 subscribers free or Mailer Lite.
If your niche doesn’t allow you to promote or build premium products (anything over around $100 per unit) then think about getting a solid mix of offerings and building it up over time. I remember Darren Rowse saying that initially Amazon Associates was a really small source of income but over the years it has really started to add up. Think eBooks, affiliates, consulting, books, etc. and you’re starting to build an income stream.
