Based on user feedback, administrators are looking to make the site more user friendly in its design. A small group of members will be trialling the new layout – all of whom requested to be a part of the trial.
Behind their thinking is a desire to allow users to navigate around the site more easily, to ensure they can find what they are looking for more quickly.
The site allows users to create a collection of images based on themes or ideas which may include hobbies, events or interests.
As well as this, pins are now bigger so that more information can be put on there, allowing for users to find related fresh content they are interested in.
The Pinterest blog read: "In addition to the changes you can see, we also made some improvements behind the scenes that we hope will make things faster.
"We'll preview the update with a small group of people over the coming weeks. Once we work out the kinks, we'll share it more broadly."
Pinterest is clearly looking to build on the momentum the site already has, with Nielsen reporting that the number of people who use the mobile app had increased by 1,698 per cent from July 2011 to July 2012.
Nielsen also found that the year-on-year (end of 2011 to the end of 2012) increase of Pinterest PC usage in the US rose by 1,047 per cent.
By comparison, Facebook saw a four per cent decline in its PC users; however, the number of people who use the Mark Zuckerberg creation far outweighs the number of Pinterest users.
The biggest increase for Pinterest was for its mobile internet visitors – which is different from those who download the app. The pinboard-style social media site enjoyed a 4,225 per cent jump during that same 12-month period.
