One of the biggest challenges in internet marketing is knowing where to focus and how to use your available time, effort, and money for maximum impact. There are countless different ways that you can go about making money online or promoting your website or blog.

The problem is that there are so many possibilities and ideas that most people tend to bounce from one to the next before ever having success. In order to succeed you’ll need to focus long enough to put in the necessary effort and time for any approach to work.

What I love about detailed case studies is that you can see the steps taken by someone else, and what they were able to achieve with their approach. Staying focused in your own work can be a lot easier when you are basing your steps off of a plan laid out by someone else, when you can see that the plan worked for them.

In this post I’ve collected a wide variety of cases studies from different blogs that I think will be very interested and practical for you. Browse through the case studies listed here and I’m sure you’ll find something that you can put into practice to improve your own business or website.
