Seven of 10 Pinterest users go to the site for inspiration on what to buy, according to a Bizrate Insights survey. That dwarfs the 17% who go to Facebook for the same reason. Forty-three percent say they go to Pinterest to associate with brands and retailers with whom they identify, compared with 24% on Facebook. Marketers can take advantage of the strong buying intent on Pinterest with PinAlerts that track people pinning their content as well as competitors' content. Other tools include the Pinery dashboard and PinPuff monitoring of the "monetary value of your pins" and traffic your pins generate, Lisa Barone writes.
