Facebook has become a huge presence on the Web. A full 24.3% of the top 10,000 websites in the world have some form of official Facebook integration on their homepage. And if you include regular links to Facebook, the number soars up to a highly impressive 49.3%.
Now after Facebook has had its much talked-about IPO, it’s worth noting how close the social network is to becoming part of the Web’s DNA. When so many websites have some form of Facebook integration, maybe we’re already there.
These numbers are from a survey of the top 10,000 websites we did this May (good old web data mining). Social has become such a force that we just had to know. By integration, we mean the ways site owners can embed things like widgets and other social plugins on their site, including for example like buttons and social logins.
And in case anyone wonders, Facebook’s official like button is on 7.3% of the site homepages.
That said, LinkedIn is different from the other three social networks in that it’s focused solely on the professional market. It’s quite possible that this has limited its appeal to site owners, who often tend to crave for volume.
If we only count site integration with official social plugins and widgets:
With that out of the way, if we count all kinds of links on homepages, not just via official plugins or widgets, the picture is quite different:
Google+ may be a young social network compared to the other three in this survey, but with the might of Google behind it, it has still managed to secure an impressive presence in a relatively short period of time.
But… When it comes to sheer amount of presence on websites, Facebook is clearly leading the pack, with Twitter not far behind.
Methodology: We examined the HTML code of the homepages of the top 10k sites in the world according to Alexa. To determine Facebook integration, we looked for the official ways of integrating Facebook on sites, with paths such as facebook.com/plugins, connect.facebook.net and graph.facebook.com. We did similar things for the other social networks, based on their developer documents and available plugin documentation. It’s a bit of a jungle. To check any links, we simply looked for anything linking to or referencing facebook.com/ or facebook.net/, linkedin.com/, twitter.com/ and so on.
