congrats! Now u can start imagine how u will feel when receiveing first payment from Google. Cheers..
Although any clicks are a good thing 4 clicks in 4 months seems like its taking way too long for any kind of result in your advertisement. Try filling your blog with plenty of SEO content in order to get free targeted traffic from the search engines.
nice work, congrats man bit of advice: don't focus on your earnings, focus more on traffic and listen to your audience is the key
