What is content marketing, and how do you measure whether it works?

Content marketing means creating material that attracts and retains an audience by being genuinely useful, rather than by interrupting them. It works by building trust and capturing demand over time.

Content maps to funnel stage:

• Top — educational articles, guides, and videos answering the questions your audience already searches for.
• Middle — comparisons, case studies, webinars, and tools that help evaluation.
• Bottom — product documentation, pricing explanations, demos, and customer stories.

Measurement, and the honest difficulty:

• Leading indicators — organic traffic, keyword rankings, engagement, email subscribers, and backlinks earned.
• Lagging indicators — leads and revenue attributed to content, and assisted conversions where content appeared in the path.
• The attribution problem is real. Content usually influences early and converts late, so last-click attribution systematically undervalues it. Assisted conversions and multi-touch models help; so does simply asking new customers how they found you.

Note: Two strong points. Content compounds — a good article keeps earning traffic for years, unlike paid media that stops the day the budget does, so the honest comparison is against an asset, not a campaign. And volume is not the goal: a handful of genuinely definitive pieces outperform fifty thin ones, particularly since Google's helpful content updates.
