Using a redirect page on my server for sponsor links?

[pussygato]

Hi, I am trying to get better at writing effective text links on my freesites and was wondering if linking my banners/text links to a redirect page (that simply increments a local counter for that link) was frowned upon. The redirect would obviously be seamless and the user would simply be sent to the paysite they clicked on. For example I would replace my sponsor links with something like http://go.mydomain.com/54/212/7498, with that url redirecting to the appropraite sponsor coded link. Thanks for your help.
