Opening up a a blog site like so many people have done already is probably the easier parts. I was curious how you charge
people to advertise on ur website
ummmm....and is it profitable if it gets known
You can charge by the CPAs but the CPMs are better because of the CPC where as the CPL is also good btu it depends on the IAB units for the nofollow attribute of the text link at the placement level if they are above the fold because of heatmap and click tracking and also the monthly charge is good but tell to pay by paypal masspay and don't tell about the I/Os is not something like WF but don't ghostfire leads and also consider the lplockdown.
What was it again?
Yes its possible.
..ask a vague question, get a vague answer
Amen.
By the way how do I make money online?
You've only posted 2 sentences on here and I'm going to tell you straight up that you need to do some work on your writing skills before anyone will read your blog. I wish I knew what direction to point you in, its just something I learned in school and have always taken for granted. Writing in proper English is essential regardless of what kind of internet marketing you are doing.
