I just got a look at Knowem's Social Media Optimizer tool and I was amazed at how many of my websites are not fully optimized for social media. You get to see all the details that your site should be doing when it comes to social media. I encourage you to put one of your websites into the url field and see what you are missing.
Without a doubt this new social media tool from Knowem will help you improve your website when it comes to social media data that your site is telling the search engines. You will see what you can improve when it comes to your site details on Facebook, Twitter, LinkedIn, and Google+. It will also show you some stats when it comes to local if your site is local based and some SEO mistakes you may improve upon.
