Last year, Twitter launched its Certified Products program to help businesses build customer relationships and analyze social data on the platform with help from a group of third party applications and services. Now, Twitter has added nine new partners to the program, including Shoutlet, Spredfast, Sprout Social, Adobe Social, Percolate, Rallyverse, Sysomos, Simply Measured, and Visible Technologies. All of these products are built for businesses and can help them manage their social media presences, either by providing insights into social trends, monitoring conversations and interactions, or scheduling and managing important updates. Certified Products are not the only ones that brands can use to manage their Twitter presence, but a certification simply means that Twitter has acknowledged the product\u2019s usefulness for businesses and that it approves of the products integrations and its use of Twitter\u2019s API and features. To become a Certified Product, partners must solve some kind of service for businesses that Twitter itself does not address. For example, Twitter does not provide analytics services for businesses to learn about their network and their customers. But Adobe Social includes real-time insights that are updated as customers interact with your brand, among other functions. Many of the Certified Products have overlapping functions, so brands that are interested in using any of the products to improve their twitter presence can sift through the list and decide which ones best suite their needs based on features, price, and any other relevant factors. Since Twitter is a pretty simple platform compared to many other social sites, offering businesses a list of third-party products that can help make sense of data and manage more complex activity gives businesses more options, and hopefully more measurable impact, when using the site to reach potential customers. When Twitter first launched the program in August, it included twelve partners, including HootSuite, SocialFlow and DataSift. The site plans to continue adding to the list, and developers can apply to be added to the list.
