How to earn from a blog?

Many people from different walks of life ask me this about making an income from blogs or websites. As if everyone is looking at alternative ways of making money. Is it because of the world’s economic recession or the improved level of awareness in the third world countries like Uganda? Before sharing what I know about making money from blogging, I want to say am proud of people like Mark Zuckerberg, Adam D’Angel and many visionaries who implemented social platforms such as facebook.com, quora.com, google.com etc…
Let’s get to it.

How can I earn from a blog or blogging?

First of all what is a blog? What is blogging?
Quoting from Wikipedia, a blog is a discussion or informational website published on the World Wide Web consisting of discrete, often informal diary-style text entries (“posts”). Click here to find out more.
Assuming we understand the definition above, blogging is the process of writing content and publishing on the blog.
Is it about text only? Text alone is not enough anymore. Therefore blogging is about podcasts and Vlogs where podcast is audio whereas Vlog is video.
Let’s briefly talk about the income bit.
Advertising
If you write informative content which people like, you will most probably attract thousands if not millions of readers(traffic). This is a great opportunity for you because many business people want to be seen. Simply create a space where adverts can be displayed and set up your pricing packages.
Reviewing
Some companies are willing to pay great reviewers to write about their products and publish on their blogs.
Affiliate marketing
Online stores like Amazon.com and advertising agencies such as google have affiliate marketing opportunities for bloggers. The good thing they can give you products links related to your content. These links are to be integrated in your blog articles so that people can click them as they read. If they like the product and buy it, you earn commission.
Tutoring
If you know something write about it and let others learn from you. Eventually this can turn into some of training from which you can earn from.
Basically that’s what I could rushy write about but it’s a diverse topic. My advice to you is to research more and start a blog.
