Why Last-Click Attribution Undervalues Meta Ads

Meta often introduces customers before they are ready to buy. Last-click attribution gives all credit to the final measurable source, which can make discovery channels look less valuable than they are.

A typical journey

A shopper sees a Meta video on Monday.

Clicks a product page on Wednesday.

Searches the brand on Google Friday.

Buys through branded Search.

Last-click reporting may credit Google completely. Yet Meta may have created the initial demand.

This does not mean Meta deserves 100% credit either

Platform attribution can swing too far in the opposite direction by claiming sales after impressions or clicks that were only one part of the journey.

Compare multiple views

Use:

  • Shopify order data
  • platform attribution
  • GA4/channel paths where useful
  • new-customer trends
  • controlled tests or geographic holdouts when possible

The goal is not to find a magical attribution model that proves Meta is valuable. It is to understand how channels interact.

Last-click is simple and useful for some questions. It is weak when you use it to evaluate channels whose main job happens early in the customer journey.
