How to Build an Attribution Model for B2B Sales Cycles Longer Than 90 Days
Standard attribution windows miss touches that happen months before conversion. Here's the extended attribution approach for long cycles.
Most analytics tools have a maximum attribution window of 90 days. B2B enterprise sales cycles commonly run 6-12 months. This means the blog post or webinar that started the journey gets no credit because it happened outside the attribution window.
The extended attribution approach uses a combination of first-party tracking (cookies with extended lifetimes), CRM integration (connecting marketing touches to deal records), and self-reported attribution (asking buyers how they found you). Combining these three sources fills in the gaps that any single source misses.
