Personally I'd live to have most media completely in the dark about visitors to solely speculate on the quality of their own content. Only metric they need is daily visitor count. Everything else can be shaped by type and quality of content. A great example is HN where we have a very targeted audience due to the content it serves. It obviously also has some sponsored articles but also the indirect benefits it has on new startups and so on. Just treat it as TV marketing and not a per person customized monetization strategy.
