Twitter has unveiled a redesign to its site and tools that offers many new features that could affect nonprofits, including the addition of special pages that allow organizations and companies a chance to promote themselves.

The new brand pages, which will be free, will allow organizations to promote a tweet to display at the top of their pages. Photos and videos can also be attached to those messages. The brand pages also provide more space for organizations to promote their messages and won’t display advertising from other groups or companies.

Twitter has already selected 21 large for-profit companies to test the pages–including Coca-Cola and Chevrolet–but those brand pages can be viewed only if your account has been upgraded to the new Twitter layout.

Other new features included in the new release that may affect your organization:

• New labels. The current links that appear at the top of Twitter pages will be replaced by new categories. Gone is “profile,” which will now be labeled “me.“  Other new labels include the words “connect” and “discover.”

• Embeddable tweets. You will no longer have to use a third-party service to add tweets to your Web site. Tweets can now be added to a Web page with a single line of code. If you use WordPress.com to host your blogs, for example, you can simply paste the URL of a tweet to appear on a Web page.

• Changes to Tweetdeck. Tweetdeck, the popular social-media management software, now defaults to use Twitter’s link-shortening and photo-sharing services, so you may have to adjust the settings to use your services. It also gives credit to the first account to send popular, often-retweeted messages.

How will your nonprofit use these new features?
