Congrat ... Is it from one site or many? How many visitors? Your Alexa Ranking? Your PR? What's your niche?
Thats a lie. Many users doing that so that you click their signatures. Look at his 2 blogs, doesn;t look too good. theres no way his blogspot site brings him 50,000 impressions aday.
He maybe lying he maynot be.. But signature links don't mean a thing.. Why would I want to link to my site from digitalpoint if it is not related to the niche.. I don't ever link to my mains sites from DP..
Wow that's really awesome. It sometimes even gets hard for me to make $100 per month. Dude are you making this from a single site or from collection of sites.
