Why last-click hurts SEO
A typical Toronto B2B journey: prospect Googles a problem, lands on your blog, leaves, comes back later via direct traffic to your homepage, fills out a contact form. Last-click gives all credit to direct, none to SEO. Reality: SEO did the heavy lifting.
GA4's default attribution model is now data-driven (machine learning across all touchpoints), which is a significant improvement over the old last-click default.
Practical attribution setup for SMBs
In GA4, switch your conversion attribution model to Data-Driven (under Admin > Attribution Settings) for the most balanced view.
Look at the Conversion Paths report (Advertising > Attribution > Conversion Paths) to see typical multi-touch journeys for your business.
For higher-stakes attribution work, tools like Dreamdata, Hockeystack, or Triple Whale provide deeper cross-channel analysis tailored to specific business models.
