Comments on Facebook and other social networking sites were unavailable on Google search because the search engine was unable to automatically read Facebook’s programming.
However, if you have used Facebook to comment on a third-party website, your comments can be searched on Google.
The change in the search engine stems from Google’s new technology GoogleBot. GoogleBot was created to find content that was once loaded in programming scripts like AJAX and JavaScript.
The website Webmonkey said Google web developers are concerned about the changes, aware the changes could upset the public once their potentially embarrassing, private comments are available through Google’s revamped search engine.
