Copyblogger is one of my favourite Blogs, and I recommend it to most people who write, especially online. Dean Rieck is currently running a series on the Blog, with his 58 of the World’s Greatest Offers series.
They are coming out over four Blog posts so it may be worth subscribing to stay in touch. The first has already been published: Offers that Raise Response and Lower Risk.
Excellent advice Craig, I reckon CopyBlogger takes a lot of beating. Over a period of time you get to read a number of guest bloggers all with a useful insight. Keep on trucking!
