I started blogging seriously on my web site, and I am looking into selling ad space. Having no prior experience in this business, how much traffic do I need to generate in order to get serious offers from advertisers? As of now, I am getting around 30 unique visitors each day, but it has been growing exponentially. Any advice would be appreciated.
Adsense is the best contextual Ads, but if you need getting sponsor you should atleast have 1,000 uniq visitors
as far as i know you should be patient and think longterm,buliding your content and getting audience should be your first priorities after that you should think about monetizing. here is a google search of problogger.net about monetizing,you can find a lot of good stuff: and specially this one is great : http://www.problogger.net/archives/2005/12/06/how-bloggers-make-money-from-blogs/
