Can you profit from an Internet Marketing Blog ? How long will it take and what are the best ways to sell a product even if it is just an affiliate product ? I am asking these questions because I have a blog on internet marketing (www.internetmarketinginformer.com) which is getting a moderate amount of traffic and has a PR2 rating. i know this is a hard "niche " to break into and competition is strong . What I would like to know is Is it worth me carrying on with this blog or should i research for a new " Niche " which will not have so much competition. I would be glad of any advice please.
