Frequently asked questions
Measure pipeline ROI first — marketing spend against pipeline value generated — because closed revenue from B2B campaigns may arrive 6–18 months after the spend. Formula: Pipeline ROI = Pipeline generated ÷ Marketing spend. Then measure closed revenue ROI quarterly with a 90–180 day attribution window. Both metrics tell different parts of the story.
Average B2B CPL from inbound content and SEO is $942. Average from paid channels is $1,907. CPL alone is not a useful metric without context — a $2,000 CPL for a $200,000 deal is excellent; the same CPL for a $5,000 deal is unsustainable. Calculate CPL against average deal value and close rate to determine acceptable CPL.
Email to existing prospects and customers consistently delivers the highest B2B ROI because the audience is already warm and the costs are minimal. Content and SEO delivers the best ROI over 24+ months. LinkedIn Ads delivers lower immediate ROAS than Google Ads but often acquires higher-quality leads with larger deal sizes in B2B contexts.
