We partake in a number of forums. One is the UK business forum.
It's quite an active forum.
There was a question on how to measure visitors to a site. One
member of the forum suggested a paid for service. We were curious
about this recommendation, why recommend a paid for service when
there are perfectly good free ones? So we took a look. Well there
was nothing there as far as we could see that was not freely
available in the various Google and Yahoo tools.
Providing paid for services which are freely available elsewhere
is not illegal. Possibly in the same manner, there are quite a few
official looking sites that make a business out of charging
(premium) for free or low cost government information (Birth
certificate sites come to mind). So we posted a comment with links
to the free tools.
Then it occurred to us that it would be worthwhile to show the
sort of free reports you can get.
