Managed to earn USD$200 today when an existing client decided to renew the ads on my blogs that were due for expiry. While it was a drop from the last year's USD$250, it is still significant enough to make me happy to know that it is actually possible to monetize my blogs when I am using a completely free blogging tool and domain.
Have also been wondering whether I should start to put more focus on selling ad space which I have not been bothered to at all in the past.
If interested to put ads on my site, please contact me at email@example.com
Pagerank 1-3 sites available with little outbound links. Price and package is negotiable.
