So if you were using the previous Facebook Like and Share buttons on your website, they should be updated automatically to match the new aesthetic, and now look something like this:
Given that these buttons are used on over 7.5 million websites and seen more than 22 billion times each day, it’s a pretty significant change. Facebook says it saw a 5 percent rise in Likes and Shares over the past month while it was testing the new buttons, so clearly users are engaging – or at least intrigued by – its new, predominantly blue designs.
Publishers can now also set the width of Facebook posts that they want to embed elsewhere on the Web. Facebook will support posts between 330 and 750 pixels wide, offering brands greater flexibility for their own sites.
