What are marketing ROI benchmarks?
Marketing ROI benchmarks measure the overall return on marketing investment — by channel (SEO, paid, email, social), business type, and company size — and provide guidance on marketing budget as a percentage of revenue.
Marketing ROI is notoriously difficult to measure due to multi-touch attribution, long sales cycles, and brand-building halo effects. The benchmarks here represent blended, multi-channel ROI over 12-month periods — not single-touch, single-campaign figures.
Measuring overall marketing ROI and allocating budget across channels is one of the most important and difficult challenges in digital marketing. This report consolidates 2026 marketing ROI benchmarks from Gartner, Forrester, and HubSpot to provide a framework for budget allocation and performance evaluation.

Strategy Recommendations
Allocate 60-70% to proven channels before testing new ones
Quick WinMarketing budget allocation research (Binet & Field) recommends 60–70% to proven bottom-of-funnel channels (search, email, retargeting) and 30–40% to brand/awareness channels. New channel tests should not exceed 10% of budget until proven ROI.
Invest in multi-touch attribution to understand true ROI
Long TermLast-click attribution over-credits bottom-of-funnel channels (Google Search, email) and under-credits top-of-funnel (social, display, content). Implementing data-driven attribution (Google, Northbeam, Rockerbox) typically reveals 15–30% of budget should be reallocated for better overall ROI.
