Content Marketing Funnel Models: 3-Stage vs 7-Layer and Keyword Intent
Map content types to funnel stages, use keyword intent, and build pillar pages for each stage.
Research intent‑based keywords, create content briefs for each funnel stage, and set up internal linking.
Summary
The guide compares the classic three‑stage funnel (TOFU, MOFU, BOFU) with a modern seven‑layer model that adds Discovery, Education, Validation, Implementation, and Amplification. It explains how to align content types and formats to each stage, from blog posts and webinars to case studies, ROI calculators, onboarding emails, and advocacy content. Keyword intent segmentation—Informational, Commercial, Transactional—is used to target the right queries at each funnel stage. The guide recommends using Semrush Keyword Magic Tool to filter by intent, auditing competitor coverage for gaps, building internal linking structures, and measuring performance with stage‑specific metrics. It encourages expanding the funnel over time to capture post‑purchase value and strengthen loyalty.
