By the end of the month, @instagram will be open to any advertiser and has expanded the number of global markets in which it sells ads from 8 to 30. This is all apart of Instagram’s new broad roll-out that began in June. When using Instagram’s ads (compared to ads running elsewhere), @Gilt (e-commerce) experienced an 85% increase in app installs. Culled from more than 25 campaigns, @Kenshoo (ad-buying firm) found that instagram’s ads cost on avg. “$6.70 for every thousand impressions, $0.51 for every click and $6.30 for every app install...people click on Instagram ads 2.48% of the time that they see them” (2.5x the avg. for social ads). - Link
