How did last-click attribution mislead a B2B SaaS company's marketing decisions?

Last-click attribution heavily credited LinkedIn's bottom-funnel content, but Bayesian MMM revealed LinkedIn's primary role was awareness—influencing Google searches that last-click then credited to Google. The model showed LinkedIn's actual contribution was 2.4× what last-click reported.

What happened when a SaaS company reallocated 25% of LinkedIn budget to upper-funnel Google targeting?

After shifting budget from LinkedIn to upper-funnel Google targeting, the company increased demo requests by 28% while reducing cost-per-demo from $340 to $218. This optimization was based on understanding each channel's true role in the funnel.

Why is last-click attribution inaccurate for lead generation campaigns?

Last-click attribution only credits the final touchpoint before conversion, missing earlier influence from awareness channels like LinkedIn that drive later searches. For a company spending $90K/month on paid media, this can cause significant budget misallocation.

What is Bayesian MMM and how does it improve lead generation ROI?

Bayesian Marketing Mix Modeling (MMM) uses statistical analysis to quantify each channel's contribution across funnel stages, not just last-click credit. This methodology helped one B2B SaaS company discover their LinkedIn investment was undervalued by 140%.

How much did cost-per-demo decrease after proper attribution modeling?

Cost-per-demo dropped from $340 to $218 after the company reallocated 25% of LinkedIn budget based on accurate attribution data—a 36% reduction in acquisition cost while increasing overall demo volume by 28%.

[Case Study: B2B SaaS, $90K Monthly Program] A B2B SaaS company spending $90K/month on LinkedIn and Google Ads used last-click attribution, which heavily credited LinkedIn’s bottom-funnel content. Bayesian MMM identified LinkedIn’s role as primarily awareness — it was influencing Google searches that last-click then credited to Google. After separating the channels by funnel stage and reallocating 25% of LinkedIn budget to upper-funnel Google targeting, demo requests increased 28% while cost-per-demo dropped from $340 to $218. The model showed LinkedIn’s actual contribution was 2.4× what last-click reported.
