When we built our self-service ad platform last March, our goal was to create an experience that would be powerful and also extremely easy for anybody to use. Whether you’re an individual looking to grow your personal brand, or an online retailer looking to increase sales, Twitter’s ad platform has the right products to help achieve your unique goals.
Over the past year we’ve listened carefully to feedback from the thousands of businesses and individuals who’ve had access to the self-serve tool, and made enhancements based on their suggestions, including more targeting and reporting in the UI.
It’s because of this feedback that effective today, we’re ending our invite-only period and opening signups for our self-serve ad platform to all users in the U.S.
So what are waiting for? Go fill up Twitter’s bank account right now!
