You may have seen an announcement from Meta regarding changes to how they attribute conversions to campaigns, effective mid-to-late March 2026. Because the official announcement was aimed at platform specialists and laden with technical jargon, we’ve written this to simplify the news and share our perspective.
Background
At the core of this change is Attribution: the tracking systems and logic advertisers use to determine the role an ad played in driving a sale.
While it is tempting to think a user sees an ad, clicks it, and immediately purchases a ticket, this is rarely the case. Most users require exposure to multiple ads across various platforms before taking that final step. Historically, the most common model was ‘last click’ attribution. This measures only the final interaction a user has with a brand before purchasing, such as clicking a Google Search ad, while disregarding the earlier advertising that prompted that search in the first place.
To ensure their ads were valued correctly, platforms like Meta built tracking that allowed them to claim a sale if a user saw, clicked, or interacted with an ad and then purchased within a specific timeframe (the attribution window).
However, the terms ‘viewed’ or ‘clicked’ are quite broad. ‘Clicks’ can include likes, comments, or expands, all of which are valuable but differ in intent. As the industry moves away from the limitations of last-click reporting, Meta is redefining these interactions to provide more clarity.
FIRST CHANGE: Redefining the Click
Click-through attribution is being narrowed. Moving forward, only users who click the specific destination link in an ad will be counted in conversion results. Currently, Meta counts ‘all clicks’ – including page likes, comments, and image clicks.
The Practical Impact: If a user saves an ad on Instagram today and then purchases a ticket later that week, Meta counts that as an attributed sale. From next week, they won’t.
By narrowing this definition, we will likely see a decrease in reported sales within the platform. Metrics like CPA will likely rise, and ROAS will likely decrease. While this might traditionally worry performance marketers, the goal isn’t to punish advertisers; it is to align Meta’s data more closely with third-party tools like Google Analytics, making reporting more consistent across platforms.
SECOND CHANGE: The Rise of ‘Engage-Through’
To ensure broader interactions are still valued, Meta is expanding ‘Engaged-view’ attribution into a new category: Engage-through attribution.
This will include the non-link interactions mentioned above, plus 5-second video views. While the definition of a ‘click’ is getting narrower, ‘engagement’ is growing. This reflects how people actually use these platforms – valuing a user who watches a full video or shares a post with a friend just as much as a direct click-through.
WHAT’S NEXT?
Currently, 99% of our performance campaigns use click attribution, as this has historically performed best. This change will be automatic, so there will be no disruption to campaign ‘learning’ phases or a need to reset ads.
Meta has not provided a forecast of the expected impact on reported data, so we will be monitoring the transition closely. We do not recommend changing creative to ‘click-bait’ headlines to chase clicks; Meta penalizes this behavior. Instead, the solution remains delivering best-practice creative that is diverse, engaging, and audience-focused.
Ultimately, we view this as a positive shift. It pushes the industry away from ‘attributed-only’ reporting and toward incrementality – placing higher value on meaningful interactions over inflated platform metrics.
THE BIGGER PICTURE
The foundation of the way forward is Marketing Mix Modelling (MMM). These tools allow us to measure the true impact of all advertising against robust, holistic data sources.
So, while the headlines might suggest you should “brace for fewer sales,” the reality is that platform-specific metrics should be secondary to the big picture metrics that actually relate to your campaign’s success.
As leaders in data and analysis, AKA will continue to assess these changes. We will be hosting a deep-dive session in eight weeks to discuss the trends we’ve observed, how the landscape is evolving, and the next steps for best-in-class measurement.
We’d love for you to join us.
