If you are a web-developer/designer, then you must have gone through times where you need to share/show off your site to your Facebook friends. You type your website URL in Facebook but you are disappointed as the site description shows some unrelated(or maybe obsolete/old meta tags) site description. What you will do is goto your site source code and check if you had made any mistake, but found that the right description of the site is there in the meta tags. You do not want to share your site with this unrelated description of your site, what to do?
Its very simple. What you need to do is enter your site's url in Debugger. That's all. Please navigate to https://developers.facebook.com/tools/debug and then there you will find an input box. Enter your site's url in the input box and then press Debug. You are done buddy..
Now try sharing your site again on Facebook, your face will suddenly lit up... That's it.
