If you shorten our site URLs, for example on Twitter or Facebook, we may use services such as goo.gl, bit.ly, tinyurl.com and ow.ly to do so, and our site works with these to rebrand our URLs as a http://www.visitbirmingham.com/xxxxx link. Also our website sometimes offers features that allow users to share links with social networks and our site may shorten that URL using one of these services.
