Post-engagement attribution windows: Select the time window for crediting Twitter with conversions that happen after a person engages with your ads. Some examples of engagement can include likes, Retweets, follows, replies, or URL clicks.
The options for post-engagement attribution windows are 1, 2, 3, 5, 7, 14, and 30 days. If you’re not sure which window to select, we recommend the default setting of 30 days. If you change this setting, your conversion data will be retroactively updated, so feel free to come back later and experiment with different attribution windows.
Post-view attribution window: “Post-view” refers to when someone on Twitter sees your Promoted Ad and does not engage with it, but later visits your website and converts. People on Twitter often see, read, and view media in your Promoted Ads without clicking on them. As such, including post-view attribution gives you insight into conversions you received but weren’t actually charged an engagement for.
The options for post-view attribution windows are Off, 1, 2, 3, 5, 7, 14, and 30 days. If you’re not sure which setting to choose, we recommend the default of “1 day after view”.
