Can't know the effectiveness of something you don't try.I was listening to a story yesterday about a Lake District mountain rescue team that had spent £18k on a new website advising people on how to go hill walking safely.
I wish I had paid more attention as Iwould like to see it as I thought it was a lot of money to spend which could be perhaps better spent.
OTOH, a website is only useful if it is drawn to the attention of, and consumed by, its intended audience.
If they have spent £18K on the site alone they're being robbed.
If they have spent £18K on the site and on promotion thereof, they're at least aiming in the right direction.
But £18K don't go very far, if you're buying publicity or advertising.
