"How do I know if marketing is working when it takes 6 months to close a deal?"

This question comes up constantly with financial advisors, healthcare practices, and professional service providers.

Here's how to measure marketing success before the sale happens:

Track Leading Indicators, Not Just Sales

Month 1-2 Metrics:

  • Consultation requests increasing

  • Quality of inbound inquiries improving

  • People mentioning they "found you online"

Month 3-4 Metrics:

  • Prospects saying "I've been following your content"

  • Referrals mentioning your online presence

  • Competitors starting to copy your content approach

Month 5-6 Metrics:

  • Shorter sales conversations (they're pre-educated)

  • Higher close rates on qualified leads

  • Prospects asking fewer basic questions

The Attribution Problem

Traditional thinking: "I can't prove this lead came from content marketing."

Better approach: Track the buyer journey, not just the final touchpoint.

Ask every new prospect: "How did you first hear about us?" and "What made you decide to reach out now?"

You'll start hearing: "I've been following you on LinkedIn for months" or "I saw your video about [specific topic]."

Metrics That Matter for Long Sales Cycles

Engagement Quality:

  • Comments from your target audience

  • Shares from industry peers

  • Direct messages asking business questions

Pipeline Health:

  • More qualified leads entering your funnel

  • Faster movement through sales stages

  • Higher conversion rates at each stage

Brand Recognition:

  • Speaking opportunities increasing

  • Media mentions and interview requests

  • Competitors referencing your content

The 6-Month ROI Formula

Month 1-3: Investment phase (content creation, audience building) Month 4-6: Early indicators (engagement, inquiries, recognition) Month 7-12: Revenue attribution (deals closing from earlier touchpoints)

Key insight: Your Month 10 sale likely started with Month 4 content.

What to Tell Your CFO

"We're not measuring marketing like a light switch. We're measuring it like compound interest."
