Twitter (unofficial Chinese name for Twitter) is an American social network and microblogging service platform, and is currently one of the top 10 most visited websites in the world. Although each “tweet” posted by users is limited to 140 characters, it does not prevent major companies from using Twitter for product promotion and brand marketing. For example, during the Christmas season of 2008, Dell achieved sales of millions of dollars through Twitter discounts alone; for another example, Tony Hsieh, the founder of the famous vertical e-commerce company Zappos, interacted with fans through his personal Twitter account and maintained Zappos’ good brand image. In addition, cross-border network marketing specialists can also use celebrities on Twitter to promote products, such as commenting on the “tweets” posted by celebrities at the first time, so that thousands of fans of celebrities will gradually know them and eventually become their fans. In September 2014, Twitter launched a shopping function, which is undoubtedly another good news for cross-border e-commerce.
In 2010, Pinterest was founded and officially launched by a team called Cold Brew Labs in Palo Alto, California, USA. Pinterest uses a waterfall flow to display image content. New images will be automatically loaded at the bottom of the page without users turning pages. In the era of mobile Internet, images are very suitable for marketing cross-border e-commerce websites because users prefer to watch images on mobile devices. Image social platforms such as Snapchat, Instagram and Flickr are also popular among users. On Pinterest, sellers can set up their own brand homepages, upload product images, and interact and share with others. In addition, cross-border e-commerce companies can also purchase Pinterest ads for marketing promotion.
