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.
Affiliate sales comprise a large chunk of revenue for most big-name bloggers. For instance, Pat Flynn made $53K last month from affiliate sales, compared to "just" $9,500 from book sales. In general, look for affiliate products with higher price points; web hosting companies are a great choice if it makes sense in your niche, with payouts of anywhere from $60-$130+ per signup.
Facebook – Depending on your niche you can expect to pay about $1 per click to your blog, but there are many variables that can influence how much you will pay. Depending on the nature of your business this can provide some excellent ROI in terms of initial sales, but the main focus of this ad campaign is to get people to your blog. Wow them with your content and get them to opt-in to your email list for more updates.
Have in-depth knowledge in your niche? Package it up into an ebook and sell it on your blog. I'd generally advise against selling it (at least exclusively) on Amazon or Kobo, as you'll probably be able to charge much less. If you've already built up a solid audience, you can probably change anywhere from $5 for a very short one, all the way up to $39+.
These three factors will determine the amount of money you make. Estimating exactly what you will make is pretty difficult, but a high traffic blog on the right topic has the potential to bring in several thousand dollars every month. Of course, many people earn less than this, and some earn even more. In fact, it has been estimated that some top AdSense publishers earn nearly $2 million per year just from AdSense.
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.
