I started my blog as a hobby after reading other blogs, then I noticed they had ads on them. I did a search on placing ads on blogs and that's how I came to know about AdSense.
This encouraged me to place AdSense ads on my blog, first I only did one ad at the top and with time I learnt how to place more ads and improved on my blog.
At first I never imaged I would soon get a check from Google for my blog because it was earning slowly, but one day I got a surprise when I was passing Nairobi town center to check my post box and got a check.
This really encouraged me to do more posts on my blog and realised one can truly earn from their blog thus making blogging interesting.
A word of caution to bloggers interested in placing AdSense on their blogs is to read the rules carefully and stick by them.
