A challenge...
Here's a good one for you:
How many people visited your recruitment site this week (or last)?
Where are they coming from?
Which is the most popular page on your site?
What page has the highest drop-off rate?
Is there a planned route through your site for every segment of your audience - and if so can you tell if it's working?
All of these questions are extremely obvious and you would probably know the answers to them if they were referring to a mailshot or printed advert. But incredibly some people responsible for the online channel cannot answer them.
