Before we talk about Traffic Sources, you must first of all realise that your channel must be attractive to viewers. How then can you make your channel attractive

1. Titles of your Videos
Put yourself in the place of the viewers, how do you search for things on google or YouTube.
I am sure you would type
How to....
Secret of.....
What to....
I got you on this right?

Since that is the way you search why not also use the same format to make your videos answers to people's questions.

Other ways of making your Channel attractive include:
2. Communicating with your Fans
3. Use call to action.
4. Create free videos that share value.

After making your channel attractive, the next thing to do is utilize free traffic sources like Quora, Facebook and Nairaland
