1-Day View Attribution

A 1-day view attribution window counts a conversion when someone was shown your ad, did not click it, and converted within 24 hours of the impression. Meta Ads Manager offers 1-day view as an attribution window, and Meta's developer announcement from October 2025 lists 1-day view among the windows that remain available for actions, conversions, and results. Meta announced in October 2025 that, from January 12, 2026, the Ads Insights API would stop returning 7-day view and 28-day view. A view means the ad was delivered to a person's screen, not that they read it or paid attention. Think of it as a weak signal that your ad was nearby when someone decided, with no proof that it influenced them.

Under the hood, the platform logs each impression, and when a conversion arrives it checks whether that person had a recent impression inside the window. The same person may also have clicked an ad, so before you add the view column to the click column, check how your platform credits someone who did both. Otherwise one sale can look like two. The 24-hour limit is short on purpose, since a view is a much weaker link than a click. It is most relevant to formats where clicks are rare, like video and large image placements, and to brand campaigns where being seen is the point. If your tool lets you compare with and without the view window, run both for a month.

Advertisers often pair 1-day view with 7-day click, but the setting is chosen per ad set, so check your own. In Google Ads, view-through conversions have their own window, which defaults to 1 day and can be set from 1 to 30 days. Both platforms report views separately from clicks. If you use a bid strategy that optimizes for conversions, the setting affects what the system treats as a success, so adding views can nudge delivery toward people who would have bought anyway. High frequency can inflate it. If the same person sees an ad ten times in a day, the view window gives the ad credit for a purchase that person may have made regardless.

The most common mistake is treating view-through conversions as incremental. Many people who saw an ad and bought within a day were already on their way to your store, or were retargeted heavily so they saw your ad many times. Counting every one as the ad's work overstates its impact. A second mistake is blending view and click conversions into one ROAS figure without noting the mix. A third is judging a prospecting campaign on clicks only when its job is to be seen, which hides any real effect from views. Some advertisers turn view windows off to keep reporting strict, and others keep them to see the full picture. Either way, do it on purpose and write it down.

To read it, split your results into click and view conversions. If a campaign shows a lot of view-through but few clicks, be skeptical and test it. The cleanest check is a holdout or lift test, where a share of the audience does not see the ads and you compare sales. This week, look at your top three campaigns, list how many conversions are view-only, and flag any where views exceed 30 percent of the total. Those are the ones where a lift test would teach you the most. Check whether your store or CRM sees an uplift in total orders when view-through goes up. If it does not, the extra conversions are only a relabeling of existing sales.
