What Is First-Touch Attribution?
A model that gives full conversion credit to the first marketing interaction.
First-touch attribution assigns 100% of the credit for a conversion to the very first interaction a lead had with your brand. If someone first discovered your company through a Google search, clicked on a blog post, and then months later attended a webinar, requested a demo, and closed a deal, first-touch gives all the credit to that initial blog post.
This model answers one specific question: what channels and campaigns are best at generating new leads? For demand gen teams focused on top-of-funnel growth, first-touch attribution reveals which investments bring new people into your world.
The limitation is obvious. First-touch ignores everything that happened after the initial discovery. The webinar, the case study, the sales calls, none of that gets credit. In a B2B buying cycle that averages 3-6 months with 20+ touchpoints, giving all credit to the first one paints an incomplete picture.
First-touch attribution works best as one view alongside other models, not as your only model. Use it to evaluate awareness channels like content marketing, SEO, and paid search. Use last-touch or multi-touch models to evaluate conversion channels. The combination gives you a fuller picture of what is working.
