We have played with livestats, webtrends, urchin and analogue over the years. all had there pros and cons. But alas we are a little out of touch with develipoments now. So we are looking for something decent withour developing it ourselves. It must be able to track PPC, run with multiple domains, track affiliates and do all the normal basic, ie keyword logging. Ideally it would be able to track organi traffic to roi also.
