Twitter has added nine new partners to its Certified Products Program, which provides Twitter-based products and services for businesses.
The new partners include Shoutlet, Spredfast, Sprout Social, Adobe Social, Percolate, Rallyverse, Sysomos, Simply Measured and Visible Technologies. The companies provide a variety of tools including analytics, listening tools, the ability to manage a Twitter presence and services that let you craft more engaging tweets. In addition, Twitter has hired former Forrester Analyst Zach Hofer-Shall to manage the program.
Twitter launched Certified Products last August with 12 partners, including HootSuite, Mass Relevance and Radian6.
The expansion of the program comes as Twitter has clashed with former partners like Instagram and LinkedIn as the company attempts to gain more control over its user experience.
