The redesign comes the week after Pinterest launched a web based analytics tool for brands to track user engagement with their sites on the social network. The analytics hub allows brands to track the number of pinners and pins collecting material from their sites, impressions and reach on the network.
From today (19 March) users will be invited to switch to the new design, which features an Amazon-style “people who pinned this also pinned” to aid discovery of new content, including that posted by brands.
Pinterest has also tidied up the way users view pins, such as being able to view pins from the same board and pins from the same source without the need to navigate the page they are on.
Other changes include bigger pins “to see more of what you love” and a fix so when users press the back button they do not lose their place on the page when browsing.
Pinterest launched in 2009 and has grown to host almost 50 million users globally, according to comScore data for November.
Last month the site was valued at $2.5bn after completing a $200 million funding round, which highlights its reliance on advertisers to bolster its revenue as it looks to convince potential and existing investors of its long term financial viability.
