First-Click Attribution
A method of crediting the first touchpoint a customer interacts with for an entire conversion or sale. It answers the question: which marketing channel first introduced this customer to your brand? CMOs use this to understand which channels are best at awareness and initial engagement.
Full Explanation
First-click attribution solves a fundamental problem in marketing: figuring out which of your many marketing efforts actually deserves credit when a customer converts. Think of it like this—when a customer buys from you after seeing a Facebook ad, then a Google search, then an email, which one actually 'caused' the sale? First-click attribution says: give all the credit to Facebook, because that's where the journey started.
This approach mirrors how traditional marketing worked. If you ran a TV commercial that made someone aware of your brand, and they later bought in-store, you'd credit the TV spot for creating awareness. First-click attribution does the same thing in the digital world—it identifies which channel first captured the customer's attention.
In practice, you'll see this in Google Analytics, HubSpot, and most marketing automation platforms. When you set your attribution model to 'first-click,' the system traces back through a customer's journey and assigns 100% of the conversion credit to whichever touchpoint came first—whether that's organic search, a paid ad, an email, or a referral link.
The practical implication: first-click attribution inflates the performance of top-of-funnel channels (awareness channels like display ads, social, and content marketing) while deflating the apparent performance of bottom-funnel channels (like retargeting or email). This matters when you're evaluating which channels to fund. If you only look at first-click data, you might over-invest in awareness and under-invest in conversion channels. Most sophisticated marketers use first-click as one lens among several attribution models.
Why It Matters
First-click attribution directly impacts budget allocation decisions. If your data shows that 40% of conversions are first-clicked by organic social, you might justify increasing that budget—but that same customer might have needed three more touchpoints to actually convert. Misreading first-click data can lead to budget waste on awareness channels while starving high-performing conversion channels of resources.
For vendor selection, you need to understand whether your marketing platform supports multiple attribution models, not just first-click. Leading platforms like Marketo, Salesforce, and HubSpot allow you to toggle between first-click, last-click, linear, and time-decay models. If a vendor locks you into first-click only, you're flying blind. The competitive advantage goes to CMOs who use first-click as context (to understand awareness performance) while also measuring last-click and multi-touch attribution to see the full customer journey. This prevents budget misallocation and ensures you're investing in the channels that actually drive revenue.

Attribution Modeling
Attribution modeling is the process of assigning credit to different marketing touchpoints that led to a customer conversion. Instead of giving all credit to the last click, it distributes value across the entire customer journey to show which channels and campaigns actually drove results.
Marketing Mix Modeling (MMM)
A statistical method that measures how each marketing channel (TV, digital, email, etc.) contributes to sales or business outcomes. It helps you understand which marketing investments actually drive revenue, so you can allocate budget more effectively.
Multi-Touch Attribution (MTA)
A method of crediting every marketing touchpoint a customer encounters on their path to purchase, rather than giving all credit to just the first or last interaction. It helps you understand which marketing activities actually drive revenue, not just which ones happen to be first or last.
Last-Click Attribution
A measurement method that gives 100% of the credit for a conversion to the last touchpoint a customer interacted with before buying. It's simple but often misleading because it ignores all the earlier marketing efforts that actually influenced the decision.
