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.
The answer is yes. However, I would caution against it. The reason is, when you use a free service, you don’t have as much control over your blog—the free service does. This can be risky, especially if you will rely on your blog for income. A self-hosted WordPress blog is my recommendation and can be started very inexpensively. See my step-by-step tutorial here.
Post your article links on social media and blog directories. Get traffic to your site with frequent updates on Twitter, Facebook, and other social media sites. Find blogging communities that match your readership and post links to relevant articles on their comments or forums. This helps in getting traffic to your site as well as raising your search engine rankings.
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.
Success in every facet of life is based on who you know and not what you know 🙂 The secret is to start connecting with more people, if you build your network wide enough you’ll meet someone who can help you, no matter what it is that you are trying to achieve. Some meet these influential people more quickly by complete luck of the draw, others need to keep plugging along longer. The system works either way, and whether or not it works better for others is irrelevant, all systems in life work better for some than others.
