Pinterest has been cautiously testing the Snapshot Marketingwaters with major brands over the past few months, and they’re now jumping in full force. The site will allow advertisers to pay to promote and boost their pins with a tag indicating sponsorship. Because Pinterest feeds are often already filled with products curated by consumers, these sponsored posts are likely to fit in more naturally than they would on Instagram or Facebook. The new ad program is Pinterest’s big push towards revenue, and creates another opportunity for brands to connect with consumers in an era of visual expression. (BostInno)
