Content Marketing ROI: Measuring Success Beyond Pageviews

Write an in-depth, data-driven article (1800-2000 words) for marketing directors on measuring content marketing ROI beyond basic metrics. The article should include: 1) Critique of vanity metrics and why pageviews/social shares are insufficient, 2) Framework for aligning content metrics with business objectives (lead generation, sales enablement, customer retention), 3) Advanced attribution models for content marketing with pros/cons of each, 4) Setting up proper tracking systems (technical overview), 5) Calculating actual ROI with formula examples and spreadsheet templates, 6) Qualitative measurements to complement quantitative data, 7) Case studies showing successful content measurement strategies from 2-3 B2B and B2C companies. Include expert quotes (fictional but realistic) and actionable takeaways for marketing teams of different sizes. The tone should be authoritative and strategic, aimed at experienced marketers looking to improve their measurement approaches.
