Over the last two weeks, my fellow Metrics Insider columnists have correctly pointed out that online metrics are neither standardized nor easily integrated across systems. Vocabulary is muddled. Numbers do not match. Data exists in silos and is isolated from related data. Systems do not adequately or easily talk to each other. Research services, ad servers, and Web analytics tools report similarly named, overlapping and often conflicting metrics. Unfortunately, these problems will not disappear anytime soon, even with emerging "standards" and continued attention paid by the industry to these important issues.
