Twitter writes: "Communicating with users isn't just about what you say. It’s also about how you say it. Now, your profile page does more to help you make an impression with a large header image for displaying your logo, tagline, and any other visuals."
According to a report in Advertising Age, such brand pages will let advertisers customize their headers to make their logo and tagline more prominent. Twitter’s Advertising Blog also notes that brands can “control the message visitors see when they first come to your profile page by promoting a tweet to the top of your page’s timeline.” The idea is to highlight your best content. The Promoted Tweet on a marketer’s profile page will appear auto-expanded to let visitors instantly see the photo or video content linked from a tweet. The new design also lets brands separate their @ replies and mentions, according to Ad Age‘s report.
