Get the window wrong and your reported conversions can look inflated, deflated, or just inconsistent with what your own MMP or CRM shows. This guide covers every attribution window option TikTok Ads Manager offers, what the defaults are, and where the setting lives. ## Table of Contents Get Up to $6000 Free TikTok Ad Credit [Claim Your Offer](https://tikadsuite.com/go/tiktok-ad-credit) ## Key Takeaways - TikTok Ads Manager defaults website and app-event conversions to a 7-day click and 1-day view attribution window. - Click-through attribution windows can be set to 1, 7, 14, or 28 days for website and Events API conversions. - View-through attribution can be set to off, 1 day, or 7 days for website and Events API conversions. - Attribution settings cannot be changed after an ad group is published; a new attribution window requires a new ad group. - App conversions through TikTok’s Self-Attributing Network use a narrower set of windows: 1 or 7 day click, 1 or 7 day engaged view, and off or 1 day view. - TikTok Shop ads use a fixed 7-day click and 1-day view window that can’t be customized, with clicks always taking precedence over views. Quick Answer TikTok’s default attribution window is 7-day click and 1-day view for website and app-event conversions, meaning a conversion counts if it happens within 7 days of a click or 24 hours of a view. Advertisers can customize click-through attribution to 1, 7, 14, or 28 days, and view-through attribution to off, 1 day, or 7 days, but only before the ad group goes live. App campaigns running through TikTok’s Self-Attributing Network use a narrower window set, and TikTok Shop ads use a fixed, non-customizable 7-day click and 1-day view window. ![TikTok Ads Attribution Windows Explained](https://tikadsuite.com/wp-content/uploads/2026/09/tiktok-ads-attribution-windows-explained-1024x576.webp) *TikTok Ads Attribution Windows Explained* ## What an Attribution Window Actually Controls TikTok’s own [attribution overview](https://ads.tiktok.com/resources/help/article/attribution-overview) describes attribution as the system that connects a user’s action after seeing or clicking an ad back to that ad. The window is the time limit on that connection. A 7-day click window means any purchase within 7 days of a click gets credited to that ad. A purchase on day 8 does not, even if the same ad influenced it. TikTok uses single attribution, meaning one conversion is credited to exactly one touchpoint: a click, a view, or an engaged view. It is never split or double-counted across multiple ads. One important distinction: the attribution window setting inside TikTok Ads Manager only controls what TikTok Ads Manager reports. It has no effect on your mobile measurement partner’s own reporting, so a mismatch between the two is expected if the windows differ. ## Website and Events API Attribution Windows For conversions tracked through the TikTok Pixel or the [Events API](https://tikadsuite.com/blog/tiktok-events-api/), four click-through options exist: 1 day, 7 days, 14 days, or 28 days. View-through attribution for the same conversions can be set to off, 1 day, or 7 days. The default, unless changed, is 7-day click and 1-day view. TikTok also lets advertisers choose how repeat conversions count during optimization. **Every** is TikTok’s labeled option for purchase-event optimization and value-based bidding (VBO). **Once** is TikTok’s labeled option for install-plus-optimization setups targeting a non-purchase goal. TikTok’s documentation names these two use cases directly but doesn’t spell out the exact counting mechanics behind each option. Match the label to your campaign’s actual optimization goal rather than guessing at the difference. This setting lives in the ad group’s Bidding and Optimization section, under Attribution settings. A Pixel that isn’t sending events cleanly is worth fixing first with the [TikTok Pixel Setup Helper](https://tikadsuite.com/tiktok-pixel-setup-helper/). Attribution windows are useless without accurate event data behind them. Once the ad group publishes, none of these settings can change. Testing a different window means building a new ad group, not editing the live one. ## App Attribution: Self-Attributing Network vs. MMP App campaigns split into two attribution paths, and they use different rules. **Campaigns running through TikTok’s Self-Attributing Network use their own window set:** - Click-through: 1 or 7 day - Engaged-view (6 or more seconds watched before converting): 1 or 7 day - Standard view-through: off or 1 day Campaigns tracked through a connected mobile measurement partner get their window configured inside the MMP itself, not inside TikTok Ads Manager. Supported partners include Adjust, AppsFlyer, Branch, Kochava, Singular, and Tenjin. Without a mobile measurement partner or [SAN attribution connected](https://ads.tiktok.com/resources/help/article/set-up-app-attribution-tiktok-ads-manager), TikTok Ads Manager only measures traffic to the app store listing. It won’t show any actual conversion data in that case. TikTok also offers direct SDK and App Events API integration as a third path, separate from MMP and SAN. That route requires working directly with a TikTok representative to get access, so most advertisers use an MMP or SAN instead. A mismatch between your MMP’s window and your TikTok Ads Manager setting is a common cause of conversion-count disputes. Keep both aligned wherever they overlap. ## TikTok Shop Ads Attribution: Fixed, Not Customizable [TikTok Shop ads](https://ads.tiktok.com/resources/help/article/about-tiktok-shop-ads-attribution) run on a different attribution model than pixel or app conversions, and the window isn’t adjustable. An order placed within 7 days of a click gets attributed to that ad. An order placed within 24 hours of a view, with no click involved, also gets attributed to that ad. When both a click and a view happen, the click gets credit, since clicks take precedence over views in TikTok’s Shop ads model. Shop ads attribution runs on your Shop ID, not on the specific product advertised. This is the same attribution logic behind [TikTok GMV Max](https://tikadsuite.com/blog/tiktok-gmv-max/), since GMV Max campaigns rely on Shop ads attribution to measure results across channels. A shopper who sees an ad for one product but buys a different item from the same shop still counts as an attributed order. A single order can never be attributed to more than one ad at the same time. One reporting quirk worth knowing: Seller Center shows same-day sales, while Ads Manager reports within the full 7-day attribution window. The two dashboards won’t match on any given day because of that gap. ## How to Choose the Right Attribution Window for Your Campaign Match the window to your actual purchase cycle, not to whichever number reports the highest conversion count. A same-day impulse product, like a phone accessory, rarely needs a 28-day click window. A considered purchase, like furniture or a course, often converts well outside a 1 or 7 day window, so a shorter setting will undercount real results. Turn view-through attribution on if you want a fuller picture of TikTok’s influence, since TikTok itself recommends enabling it for that reason. Keep it off only if your reporting needs to isolate click-driven conversions specifically, such as for a strict last-click model shared with other channels. Decide your window before the ad group goes live, since there’s no way to adjust it afterward without starting a new ad group. Once results start coming in, the [TikTok Ads ROAS Calculator](https://tikadsuite.com/tiktok-ads-roas-calculator/) can help sanity-check whether your chosen window is under- or overcounting real revenue. ## Mistakes That Distort Attribution Data Leaving the default 7-day click and 1-day view window in place without checking whether it fits the product is the most common mistake. A mismatched window either inflates apparent performance on short-consideration products or undercounts it on longer-consideration ones. Comparing TikTok Ads Manager numbers directly against Google Analytics or another platform’s last-click numbers, without accounting for TikTok’s own window, is the second mistake. Different platforms use different attribution logic, so a raw number-to-number comparison will rarely match. Assuming Shop ads attribution works like pixel attribution is the third mistake. Shop ads use a fixed window and a Shop ID-based model, not the customizable, product-level tracking pixel conversions use. Trying to edit attribution settings on a live ad group is the fourth mistake. The setting locks at publish, so the fix requires building a new ad group entirely. ## Frequently Asked Questions ### What is TikTok’s default attribution window? 7-day click and 1-day view, for website and app-event conversions tracked through the TikTok Pixel or Events API. ### Can I change the attribution window after my ad group is live? No. TikTok locks attribution settings once an ad group publishes. Testing a different window requires creating a new ad group. ### Does TikTok Shop use the same attribution window as regular ads? No. TikTok Shop ads use a fixed 7-day click and 1-day view window that can’t be customized, and attribution is based on your Shop ID rather than the specific product advertised. ### What’s the difference between view-through and engaged-view attribution? View-through attribution credits a conversion to anyone who saw the ad without clicking, within the set window. Engaged-view attribution requires the viewer to have watched the ad for at least 6 seconds before converting. ### Why don’t my TikTok Ads Manager numbers match my MMP’s numbers? The attribution window inside TikTok Ads Manager only affects TikTok’s own reporting; it has no effect on your mobile measurement partner’s reporting. If the two use different windows, a mismatch is expected, not a sign of tracking error. ### Should I turn on view-through attribution? TikTok recommends enabling it for a fuller picture of an ad’s actual influence, since click-only attribution misses conversions from people who saw but didn’t click an ad. ## Wrapping Up TikTok’s attribution window decides which conversions get credited to which ad, and the wrong setting quietly distorts your reported results either direction. Website and Events API conversions default to 7-day click and 1-day view, with click options up to 28 days. App conversions split between TikTok’s Self-Attributing Network and MMP-based tracking, each with its own rules. TikTok Shop ads use a fixed window you can’t touch at all. Set the window to match your product’s actual purchase cycle before the ad group goes live, since there’s no editing it after. **Sources** - [About the attribution window on TikTok Ads Manager](https://ads.tiktok.com/resources/help/article/about-the-attribution-window-on-tiktok-ads-manager) - [How to create attribution windows for your ad group](https://ads.tiktok.com/resources/help/article/attribution-settings-at-the-ad-group-level) - [Attribution overview](https://ads.tiktok.com/resources/help/article/attribution-overview) - [Set up app attribution in TikTok Ads Manager](https://ads.tiktok.com/resources/help/article/set-up-app-attribution-tiktok-ads-manager) - [About attribution for TikTok Shop ads](https://ads.tiktok.com/resources/help/article/about-tiktok-shop-ads-attribution)
