According to a new study by website monitoring service Pingdom, 24.3% of the top 10,000 websites in the world as reported by Alexa now feature some form of official Facebook integration on their homepages
Counting all kinds of links and official widgets, here is Pingdom’s final count:
- Facebook: 49.3%
- Twitter: 41.7%
- Google+: 21.5%
- LinkedIn: 3.9%
I would have suspected these numbers would be higher. My local DNS server hijacks all facebook requests so I see every time facebook.com tries to phone home from my browser.
