It used to be easy to find an official Twitter account. You'd go to Google, type in the name of the company or celebrity or product and the official (or squatted) Twitter account using that proper noun came out on top. Not any more.
As of this writing if you Google up any company name or celebrity - even a dead one - and also include the word Twitter, Google will now prioritize a real-time stream of results over the official presence. This basically bumps anyone down slightly who was hoping to set up a Twitter account for SEO. A gallery of examples follows.
Oh and it's not just big names either. It applies to me as well.
