America’s fastest growing companies are more likely to have corporate blogs than those listed on the Fortune 500.

Just 144 Fortune 500 companies have a public-facing corporate blog, with 35% of these coming from the top 100.

Twitter is causing more of an impact. Sixty-two per cent of Fortune 500s have an active account they have tweeted from in the past 30 days. The list’s leaders are also more likely to have an account than their counterparts further down the rankings.

Top of the Tweeters is Google, which has picked up 4,350,098 followers and boosted its account by 23% in only five months. In its shadow is Whole Foods, Google’s main rival but still lagging two million followers behind the internet giant.

Surprising perhaps, only 58% of Fortune 500 companies have a corporate Facebook account – a tiny 2% improvement on the previous year’s figures. And their Facebook pages are slipping too. Insurance, retail, telecommunications and even computer companies’ pages have dropped in the past year.

Coca-Cola sets the record for being the company with the most fans with 40,094,541 likes and easily out performing its nearest rival Starbuck, which picked up almost 29 million likes (click to enlarge).
