Will NASCAR driver Danica Patrick win the Sprint Cup at the end of the season?  Not a chance.  However, Patrick is the most effective celebrity for pushing their sponsor's social media buzz. 

Go Daddy, Danica Patrick's main sponsor, will like these results from Synthesio, which monitors social media.  Patrick is four times more effective at promoting Go Daddy than her nearest competitor, singer Rihanna  is at promoting Cover Girl make up.

Celebrities Twitter feeds were monitored by Synthesio and Patrick generated almost 13% of Go Daddy's total social media buzz.  Rihanna generated just over 3% for Cover Girl and basketball star Le Bron James generated just under 2% for sponsor Nike.
