When learning about Google AdSense , i came across two different school of thought , the first one suggest you to produce as many low quality adsense site as possible , usually from 100 to 300 sites per month , putting 10,000 to 20,000 keywords in each of them and hoping to earn few bucks from adSense, for example if each of the site from the 300 adsense sites earning you 1 dollar a day , it will be 300 a day and 9k a month , the phylosophy behind : you don't want to sell a one million dollar orange, you want to sell a million ONE dollar oranges! .
Another school of thought is to produce few sites but with high quality information to your visitor, for e.g. you might have 3 high quality sites earning you 100 dollar a day , which is 300 a day and 9k a month.

Of course the later required a lot of effort to generate the "Authority site" and it is no surprise that many will opt for the first option , they bought prebuild adsense site , hundreds of ghost written PLR articles and mass publishing them . Many of them have earn good money by selling a million ONE dollar oranges .

After reading John's report i finally make up my mind to go for the "Authority site" option , i want to build my niche that will benefit my reader , build up the reputation in the niche and growing constant traffic , i have set my mind , i have one goal and what i need to do is "Action" :)
