I am writing today because I have found one that DOES WORK and is easy to use and is cheap, especially when compared to some of the tools I have tried that DO NOT WORK.
The tool is a web site and Cheome Extension called Snip.ly
Here is my test. I created 4 "Snips" and posted to Facebook, Twitter, Pinterest and Buffer that hit LinkedIn as well. 50% had clicks and 1 led to a conversion, no other tool or test I ever tried did as well.
Click here to see the sample test I posted.
You want 50% of your posts to generate clicks, or 50% of your clicks getting a conversion, then go to Snip.ly and sign up.
