Click-Through Conversions vs 1-Day View Attribution: Action or Exposure
In short: Click-through conversions is the umbrella for any conversion tied to a prior click, measured under whatever click window an account has active; 1-day view is one fixed, narrow setting in a completely separate category, crediting only an ad that was seen, with no click at all, within 24 hours. They differ on two axes at once: what interaction is required, and how pinned down the timeframe is by definition. Click always takes precedence over view for the same person, so click-through conversions structurally outranks 1-day view whenever both could apply. Lean on click-through conversions for delivery and budget decisions; read 1-day view as a smaller, supplementary window into pure exposure effects.

Click-Through Conversions
Counts conversions from people who clicked your ad first, credited back to that click within the campaign's click attribution window.
The stricter of the two counting paths: a recorded click ties the person to the ad, then any conversion inside the click window is credited back to it. These are the numbers most advertisers optimize on, and platform bidding systems lean on them heavily. The subtlety is that a click conversion is not proof of causation either, it just documents a much stronger interaction than an impression.
Full definition1-Day View Attribution
Counts a conversion when someone saw the ad without clicking it and converted within 24 hours of that impression.
A view means the ad was served and rendered to the person, not that they engaged with it, and clicks take precedence, so a view-through is only counted when no click exists in the window. It pairs with 7-day click as Meta's default setting. The frequent misreading is treating view-through conversions as incremental; many of those people would have converted anyway, which is what a lift test exists to check.
Full definitionSide by side.
The differences that actually change what happens in your account.
| Click-Through Conversions | 1-Day View Attribution | |
|---|---|---|
| What has to happen to earn credit | Any click, credited under whichever click window is active. | The ad being seen, with no click at all, within a fixed 24 hours. |
| How pinned to a specific timeframe | Flexible - can be measured under a 1-day, 7-day, 28-day, or other window. | Fixed - locked to a single 24-hour view window by definition. |
| Which one wins if both could apply | Takes precedence over a view every time. | Only counted when no click exists at all for that person. |
| Weight in automated bidding | Generally the primary signal, regardless of which window is chosen. | Usually supplementary, reporting-oriented rather than the main lever. |
| Evidential strength | Stronger across the board - documents an actual action. | Weakest tier - documents exposure only, with no interaction on record. |
| Failure mode | Assuming it always means a tight, single-day window like 1-day view does, when it could be running under a much longer one. | Assuming a near-zero number here means the campaign underperformed, when it may just mean most converters also clicked. |
What actually separates them.
Click-through conversions can be measured under any click window an account has set, while 1-day view is locked to a single, specific 24-hour view window by definition - one is a flexible category, the other a fixed setting.
Click always takes precedence over view for the same person, so any conversion that could qualify for both gets reported as a click-through conversion, never as a 1-day view one.
Click-through conversions, regardless of which window is chosen, generally carries more weight in automated bidding than 1-day view, which is typically treated as a supplementary reporting signal.
Because 1-day view requires no click on record, it structurally cannot include anyone already captured by click-through conversions - the two draw from disjoint groups of people, not overlapping ones.
A report showing a healthy click-through conversions number alongside a near-zero 1-day view number isn't necessarily a weak campaign - it usually just means most people who converted also clicked at some point, which is normal for lower-funnel, high-intent placements.
Which one should you use?
Use Click-Through Conversions when
- You are comparing click-based performance across campaigns that use different window lengths.
- You are auditing a report and need to confirm whether 'conversions' actually means click-through before trusting it.
- You are feeding conversion data into a bid strategy and want the signal it primarily weighs.
- You need a number that closely matches your landing page's own click-tracking, whatever window it runs under.
- You want a term for conversions that came through an actual click, without committing to a specific day count.
Use 1-Day View Attribution when
- You are running display, video, or upper-funnel social where impressions vastly outnumber clicks.
- You want visibility into people who saw the ad, never clicked, but converted anyway.
- You are running a brand campaign where exposure itself, not a click, is the intended outcome.
- You have, or plan to run, a holdout or lift test to check whether the number is incremental.
- You want the tightest, least speculative version of exposure-based credit available.
Common questions.
If I only look at click-through conversions, am I missing anything real?
Potentially, yes. People who saw the ad, never clicked, but converted anyway only show up under 1-day view, so a click-only report misses passive exposure effects - something that matters more for video and display placements than for lower-funnel, high-intent formats.
Why is my 1-day view number so much smaller than click-through conversions?
Because click always outranks view for the same person, and most people who genuinely convert after seeing an ad tend to click at some point in the process, leaving a comparatively small remainder with no click on record at all.
Should I optimize toward click-through conversions or 1-day view?
Click-through conversions, in general - it is the stronger evidence and the signal most bidding systems are built to chase. Treat 1-day view as a supplementary number for understanding pure exposure effects, not as a bidding target on its own.
Or stop choosing between them.
