Inbound Marketing Fundamentals
Inbound Marketing Fundamentals checks whether you understand the flywheel model and can explain how inbound differs from outbound in method, in philosophy, and in how it is measured.
The flywheel, not the funnel
HubSpot replaced the linear funnel with a flywheel because momentum compounds: happy customers fuel word-of-mouth, which feeds new attraction. Two forces slow the wheel - friction (anything that makes it harder to buy, get answers, or get help) and leakage (contacts dropping between stages). Your job is to store energy by delighting customers, not merely to push people through.
Core rules
- Inbound is pull-based: you earn attention with useful content instead of interrupting.
- Each stage has its own goal - Attract: qualified visitors; Engage: leads and opportunities; Delight: promoters and referrals.
- Content is the engine, the CRM is the memory, automation is the accelerator.
- Delight is measured with retention, referral traffic, and satisfaction, not new contacts alone.
Worked example
A B2B software team reports traffic up 40% while new customers stay flat. Reasoning: attraction improved, so the bottleneck is elsewhere - likely friction at the marketing-to-sales handoff. The fix is not more blog posts; it is auditing the demo form, removing unnecessary fields, and setting a sales follow-up SLA. That treats the flywheel as a system and targets the constraint.
Traps
Equating inbound with "content marketing only"; assuming traffic growth always converts to revenue; treating delight as an afterthought; reporting funnel metrics inside a flywheel model.
