Adsense is one of my favorite money makers and my most steady stream of Adsense income comes from a site I built in 2010. I created some nice content back then and I just left it there.I made only $10 a month from the site in the first year and after some very frustrating ups and downs, it’s gradually climbing up. Now, 4 years later, it’s averaging $600 a month. To be honest, I never actually spent much time on it at all. No link building nor frequent content updating no nothing and it’s now making me 600 bucks a month. Not much, but still.Not only is it receiving large amount of steady traffic, new content are generally very well positioned in front spots in search engine results. The older the site, the more authoritative it can get from search engine’s point of view.Time is the ultimate distinguisher between builders and spammers. Spammers come and go, hit and run. They are always impatient, looking to make the quick buck with a spammy site. Once they find it’s not profitable, they’ll stop renewing the domain after the 1st year. Google knows this too well.So most of your sites would not actually start performing in terms of search engine traffic until at least 1 year after domain registration. Yet most people are too obsessed with quick results and never wait that long. They kill their sites just before they can make them decent money.
