A good portion of the British Government has no clue if their websites are effectively reaching their audience or not.
Around 16% of government departments did not know how their own websites were being used by tax payers, and almost a quarter were not aware of the running costs, according to the COI report.
Very few companies have any idea of why they have a website, they just know they need one, so it's not surprising government is the same way.
Websites don't exist in a vacuum: They need a reason to exist that is measurable and actionable. It can be something as simple as a contact form submission or something complex as Amazon.com, but without a reason WHY, there's no reason for a website at all.
