"Its interface is cool" is the first reaction of many users, and the waterfall's web page display mode has brought great impact to the vision. Meanwhile, interest is also an interesting new element. Users gather and interact because of the same interests, and have a pleasant discussion and experience sharing through Pin /Repin. Moreover, the simple interaction of web pages directly grabbing pictures satisfies users' natural "collecting addiction" characteristics, and pictures have links to source pages, forming a powerful marketing platform. In addition, it allows you to add a short title and introduction to the picture and mark the price. This platform, where you can promote your own art and products, has attracted all kinds of original artists and designers to join. However, Pinterest also faces challenges. Because social networking sites usually implement a free policy for users, Pinterest cannot directly convert traffic into revenue. How to make Pinterest profitable is one of the main challenges facing the company. Websites like Pinterest have many ready-made business models, such as brand advertising (placing targeted advertisements according to layout content), corporate membership (B2B provides layout for companies to publish product information pictures), e-commerce (B2C clicks on pictures to directly sell products), and picture storage (setting up free services and paid membership services). Judging from the order of magnitude, activity and growth rate of Pinterest users, brand advertisements and corporate members will be a good and stable source of income. According to statistics, the mainstream users of this website are housewives, mothers, handy people, cooking lovers, brides-to-be and related people. This will make it a more accurate and effective platform for female users to provide advertisements for enterprises in terms of diet, fashion and wedding. If you develop into an e-commerce, you can learn from Fancy's successful model. Users can browse the web, collect their favorite items and find people with similar interests. Pinterst can make social recommendation step by step by collecting consumption data and access to e-commerce in the future. Previously, both Facebook and Twitter had achieved rapid development without a business model. Ben Silbermann, co-founder of Pinterest, said that he was pursuing the same trajectory. At present, the number of Pinterest users is equivalent to about 1/3 of Twitter, which is already considerable. If Pinterest has enough financial support, the website will continue to grow and the management will have enough time to explore business models. The good news is that Pinterest recently confirmed a $27 million financing, and the company was valued at $200 million. In addition to the profit model, Pinterest also faces the threat of predators. These map-reading websites with simple functions should quickly establish barriers, otherwise they may be swallowed up by social giants. However, unlike traditional social networking sites, Pinterest focuses on interests rather than friends, and the content it creates is persistent. Timelines and news streams on Facebook and Twitter are fleeting, while Pinterest's thumbtack board is still there. From the perspective of e-commerce, this will be a shopping process of discovery rather than search. We go to eBay or Amazon with keywords, provided that we know what we are looking for, but the question of how to find what we are looking for is still unanswered. Pinterest can use interest groups to solve such problems, which can help us find what we want and build a one-stop shopping service. More importantly, for photo collectors, it takes a lot of time and energy to collect the whole photo. All these features will increase the cost of user platform transfer and stabilize Pinterest's position.
