The reason this section is called “Great Content” is because your content really does need to be of a high standard. Everyday millions of blog posts are published on the internet and with so much competition for our limited attention spans you really have to be creating blog posts people are going to want to read and perhaps even share on social media or on their own blogs.
One of the great things about email marketing is that it is extremely cheap. Not only is it cheap, but if done the right way it is extremely effective. It allows you to reach your subscribers to provide them with information about your blog, and you can even choose how often you send an email. It is a great way to bring in customers and experience growth in revenue, whether it gets them to click through to your site, purchase a product or service or take interest in your blog.
If you want to be famous or reach a wide audience, you will have to choose something slightly broader and work hard to make the best content for that topic. A subtopic relating to fitness, finance, or relationship advice is likely to reach the most people. Consider specific but broadly applicable topics such as managing money in college, or a marriage counseling blog.
The truth is, it's not as easy to carve out your space on the web and make a name for yourself as a blogger today, as it was back when blogging was brand new. And it takes a lot of time to build your audience to the point where it's successful. (The most successful, multi-million dollar blogs today were started around 2005 or earlier.) So it's definitely not something you can get rich quickly with, though many people do work on their blogs full time.
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. ; )
Making money through blogging requires a carefully thought out topic. If you have an existing blog with a small audience, be honest when considering whether the topic has broad appeal that isn't already covered by other established bloggers. If it does, great! Otherwise, there's nothing wrong with starting a second blog that will be more successful in attracting an audience, marketing itself, and making money through a variety of methods described below.
Allow readers to purchase your own products or donate to your cause through your blog. If you have an online store for selling arts and crafts, or you create T-shirt designs available through a clothing website, provide links to those sites. Including a PayPal button for quick, safe purchases or donations is a common way to monetize creative blogs, or blogs that provide free advice or assistance to those who can't afford it.
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.
Email is a great way to deliver other forms of content. With Convertkit, I am able to also create free email courses that can automatically be sent out to my subscribers. This makes life easy because all a reader has to do is sign up, and then Convertkit sends out all the information that they need and drips out the content day by day (or whatever timeframe I choose).
