I signed up for adsense in the year 2005. After four long years of struggle my adsense in on a roll now. I've develop big sites, very big sites and placed adsense on them. But my adsense income never matched my hard word. It was very low. Frustration lead me to close all the sites I did. That was from 2005 to 2007 end. In 2008 I was completely away from adsense. But I loved adsense so much that the failure in it was itching my mind very often. Then came the year 2009. I decided to take a plunge into adsense once again. This time my prepared a plan quite opposite to the plan i applied before. Previous Plan INVESTMENT + HARDWORK Current Plan NO INVESTMENT + SMARTWORK I prepared to develop a free blog with blogger. Its was about letter formats. I gathered so many letter formats from all available sources maninly from friends. They used to email me their appointment oders, job offer letters, resignation letters, business letters so on. I modified all those letters, started my free blogspot blog. I prepared about 60 posts before hand and posted 3 each day. I posted a link to my blog where ever possible genuinely. didn't spam at all. Got Very few viewers and they found it very useful and i think word of mouth got me more viewers. Later i converted my free blog into a direct domain (aletterformat.com) once my adsense income started flowing in. Later I went on to develop (aresumeformat.com) too. All with in Jan 2009 to Nov 2009. Smart work is simple. Give useful stuffs to your viewers. Do good research on your main key word. Dont go behind an already flourised concept. Find new things. Or else find a new way of presentation for a old concept.
