congrats on making a few K a month... make sure to branch out, outside of Adsense i am making good money on adsense and other programs but don't quite yet have the confidence to leave my day job untill i have plenty stored in the back as that 1K when self employeed gets taxed more heavily in us then while employeed at another job...
Errrrr, you think I'm stupid or something No, I'm not leaving my dayjob yet, not for a 1k from AdSense. But I'm leaving it soon, because I have learned lots of things from this forum (and little from other places too) and I have good solid plan how I can multiply my income in short time. I have good plan of how I can multiply my best site so that I can reach 4k level with those sites. 4k or even more. Multiplying my site means that I use same idea, but with whole new content. Every new site will bring 50% of income comparing to my original site and I have calculated that I can do it up to 6 times. Besides AdSense I have bunch of affiliate programs I'm participating and I own part of a webshop, so AdSense isn't my only income source. And then I'm consulting small business owners to use AdWords as an advertising channel. Isn't that smart - I teach people to give me more money via Google. And they are even paying me about it. So, what I'm doing for my dayjob? I drive a cab. If I don't make all that money I have planned, I can allways go back behind the wheel. My plan is quite safe.
Thanks for you really good and important tips to improve adsense earning. Good luck for your new job.
