I joined 10 Linkedin groups in one of my niches and shared my blog post to those groups.
This resulted in nearly 300 visitors from my target market arriving on my blog within the 24 hour period following the posting. (There was a noticeable delay of four hours before the traffic started flowing)
I got some opt-ins, sales and a few potentially lucrative offers. It was a good result.
I'm now going for one post a day shared through the Linkedin button. It seems a very easy way to build up 300 visitors a day to a blog, which could be useful if you are starting out.
I'll also be looking at making my content more viral, as 300 people a day are a good enough block to start off a viral campaign.
