What Is View-Through Attribution on Meta Ads?

View-through attribution on Meta Ads credits a conversion to an ad that the user saw but never clicked, capturing purchase influence from ad exposure even when no direct click occurred.

How View-Through Attribution Works

When a user sees your Meta ad but does not click it, Meta records the impression. If that user later visits your website and completes a purchase within the view-through attribution window (1 day by default), Meta attributes that conversion to your ad.

This means Meta can claim credit for a sale even if the customer:

As long as they saw your Meta ad within the preceding 24 hours, Meta's 1-day view attribution window credits the conversion.

Meta's Default Attribution Windows

Meta's default attribution setting is 7-day click + 1-day view:

You can see these attribution settings in Ads Manager under column customization, or by clicking on a campaign and reviewing attribution settings.

Why View-Through Attribution Inflates ROAS

The problem is straightforward: users who saw your ad but did not click were likely going to purchase anyway through another channel. The ad may have had zero influence on the purchase decision.

Consider a brand spending $20,000/month on Meta. According to Meta's reporting, they generated $80,000 in purchases (4x ROAS). However:

The $25,000 view-through revenue includes a significant percentage of buyers who would have purchased organically. The true incremental value of view-through conversions is typically 30-60% of the reported value.

This inflation makes Meta's reported ROAS look better than its actual impact on your business.

When View-Through Attribution Is Valid

View-through attribution is not entirely fictional. Some percentage of view-through conversions represent genuine influence:

Brand reinforcement: A user who was considering purchasing sees your ad, does not click it, but is reminded to visit your site directly later that day. The ad genuinely influenced the timing of their purchase. Upper funnel influence: A user who has seen your product multiple times without clicking eventually searches for your brand on Google and purchases. The Meta impressions contributed to brand awareness even without direct click-through. High-frequency campaigns: Users who have seen your ad 5+ times may finally decide to purchase without clicking. The accumulated impression effect is real.

The question is what percentage of view-through conversions represent genuine incremental impact vs organic buyers Meta is claiming credit for. Most research suggests the incremental rate is 20-40%.

How to Adjust Attribution Settings

To view Meta performance with click-only attribution (removing view-through):

    • In Ads Manager, click "Columns" dropdown
    • Select "Customize Columns"
    • In the attribution window section, deselect "1-day view"
    • Select "7-day click" only
    • Compare your ROAS with and without view-through
You can also change default attribution at the campaign level for more accurate ongoing reporting.

MHI Media typically reviews performance using three attribution windows simultaneously:

Comparing Attribution Windows

The spread between these windows reveals how much view-through is affecting your numbers.

Example data from a real DTC account:

The $20,000 difference between max and min attribution is almost entirely attributional, not real revenue difference. The "true" ROAS is somewhere between 2.0x and 3.8x depending on how much view-through is incremental.

Most DTC brands use 7-day click as their working ROAS benchmark and acknowledge that view-through inflates the platform number.

Key Takeaways

FAQ

Should I turn off view-through attribution?

You cannot fully turn it off, but you can view reporting without it by selecting "7-day click only" in column customisation. Keep the default reporting to compare with industry benchmarks and to maintain consistency in your own data over time. Just understand that the default number is inflated relative to true incrementality.

How does view-through attribution differ from click-through attribution?

Click-through attribution credits conversions to users who clicked the ad. View-through attribution credits conversions to users who only saw the ad. Click-through is more reliably incremental because it requires user action. View-through is more ambiguous because many of those users would have converted without the ad.

Does view-through attribution affect campaign optimisation?

Yes. When Meta's algorithm optimises for conversions, view-through attributed conversions are counted alongside click-through conversions. If view-through makes up 30% of your conversions, the algorithm is partly optimising toward users who respond to impression-level exposure, not just intent-driven clickers. This can be good (broad influence) or neutral (organic buyer interception).

Is view-through attribution the same on Google?

Google's equivalent is search attribution and assisted conversions. Google Analytics attributes conversions to the last non-direct click by default. Google does support view-through conversions for Display and YouTube, but they are reported separately and not included in default conversion counts, making Google's reporting more conservative than Meta's.
