Data and references for the Max CPC article
Source materials, citation guidance, and the underlying benchmarks that inform the funnel-math derivation in the parent article.
What this page is
The parent article at cpccalculatorhub.com is an encyclopedia-style derivation of the maximum profitable cost-per-click. The derivation relies on industry-typical benchmark values (deal value, margin, close rate, click-to-lead rate) drawn from multiple sources. This page documents those sources and provides the methodology for the vertical-benchmark table in the article.
Vertical benchmark sources
The vertical-typical values for B2B SaaS, legal services, insurance, healthcare, home services, and fintech are aggregated from:
- WordStream Google Ads Benchmarks Report (2024 edition, updated quarterly), aggregating CPC, CTR, and conversion-rate medians across 31 industries.
- SaaStr industry surveys (2024–2025) for B2B SaaS deal-value and close-rate benchmarks.
- HubSpot State of Marketing reports (2024 and 2025 editions) for B2B funnel conversion rates.
- Operator data across ~25 agency client accounts in the relevant verticals, anonymized and aggregated.
Where the published sources conflict, the median across sources is taken. Outliers (specifically, vendor-published benchmarks that conflict with multiple independent sources in a self-serving direction) are excluded.
