According to this WIRED article, +1 Google is investigating wether to consider it as a signal in future updates of the search engine.
Google confirmed its plans in an e-mail to Wired.com.
“Google will study the clicks on +1 buttons as a signal that influences the ranking and appearance of websites in search results,” a spokesman wrote. “The purpose of any ranking signal is to improve overall search quality. For +1’s and other social ranking signals, as with any new ranking signal, we’ll be starting carefully and learning how those signals are related to quality.”
So, for now at list, the pages you are +1-ing will not change ranking.
