I have been displaying Google ads on my website since the beginning of this website last year January. The earnings are as follows:
As you can see, the main source of income comes from my root domain, which is shaunlgs.com. The subdomains generated far less income, almost nil compared to the root domain. This is because I have spent the most time on shaunlgs.com, writing contents compared to the subdomainds. I have recently launched cs.shaunlgs.com and I hope that will be more popular than shaunlgs.com. Since last year’s January till now, which is almost 22 months, I only earned around 9 USD! This is too low. My daily views are around 60 people. The most viewed posts of shaunlgs.com are related to Moocs – CS50x and MIT 6.00.1x.
