1) build a quality website that adds value to the internet 2) Apply for an Adsense account at google.com/adsense; Google will review your website and if they agree that it adds value to the internet, they will approve your account 3) sign-into your new Adsense account, click "my ads", setup your ads (read the instructions) and paste the code into your website where you want the ads to be displayed 4) continue working on your website, adding content and making sure it is not just another shitty, spammy MFA website designed just to try and squeeze money from Google 5) drive traffic to your quality website 6) continue to read the forums here and at other webmaster/adsense forums, blogs, etc, to learn more 7) Sit back and watch the money roll in!
Yes, it's the same with blogger.com. I think it's actually easier to add your code on Blogger. Everything else is the same. Please be sure that you create a quality website and not a shitty, spammy, worthless site with the sole intention of trying to make money..
All good advice here, personally I may be inclined to get some traffic flowing before putting the Adsense ads on, then it won't appear as a MFA (even if it is)
I think it is better to wait until your Blog / Site getting at least 100 unique visitors per day before you add Adsense. All the advises given by Tearabite are excellent.
leave it on us and sit back and relax and let ur site do the talking, just make sure u have a google adsense account thats it!!
