Temporary attribution

What is Temporary attribution?

Temporary attribution is an attribution model that assigns credit for a mobile app install or in-app conversion to a specific marketing campaign or channel for a defined, limited period of time. The model evaluates touchpoints occurring within a set window, such as a fixed number of days after an install or conversion event, to determine which campaign deserves credit. Once the attribution window expires, no further credit is assigned to that touchpoint.

How it works

Temporary attribution works by establishing a time boundary around the conversion event. When a user installs an app or completes a conversion, the attribution system looks back across recent touchpoints, within the defined window, and applies a credit rule, most commonly last touch, to assign that conversion to a specific campaign or channel.

Attribution Window Boundaries

The time window is configured in advance by the marketer or measurement platform. Common windows range from 1 to 30 days for click-based attribution and 1 to 7 days for view-through attribution. Any touchpoint that falls outside the window is excluded from credit consideration, preventing older, less relevant interactions from influencing current performance data.

Touchpoint Evaluation

Within the active window, the attribution model evaluates recorded touchpoints such as ad clicks, impressions, or other engagement signals. The model then applies the configured logic, for example last-touch or multi-touch, to distribute credit. This ensures that campaign performance data reflects only timely, relevant interactions rather than long-past exposures.

Credit Expiry

Once the attribution window closes, the temporary nature of the model takes effect. Conversions that occur after the window ends are not credited to campaigns that drove earlier touchpoints. This design keeps attribution data clean and aligned with the actual recency of marketing influence.

Why it matters

Temporary attribution gives marketers a structured, time-bound view of campaign effectiveness, which is essential for making accurate budget decisions. Without a defined attribution window, older touchpoints can receive unwarranted credit for conversions that were driven by more recent campaigns, distorting performance data.

By limiting credit to a specific time period, marketers can compare campaigns on a consistent basis, identify which channels drive timely conversions, and reallocate budget toward higher-performing initiatives with greater confidence. This is especially valuable in mobile marketing, where user decision cycles can be short and campaign overlap is common.

Temporary attribution also supports ongoing optimization. Marketers can set a window for a new campaign, measure outcomes within that period, and then compare results against prior campaigns using the same time boundary. This consistency makes it easier to isolate the true impact of strategic changes, such as creative updates, new channels, or adjusted targeting parameters.

Mobile measurement partners (MMPs) like Airbridge provide configurable attribution windows that enable marketers to implement temporary attribution across multiple campaigns and channels, ensuring that credit assignment reflects genuine marketing influence within the relevant time frame.

How to set up temporary attribution for mobile campaigns

Setting up temporary attribution requires defining clear window parameters before a campaign launches and ensuring your measurement infrastructure enforces them consistently.

1. Define your attribution window length. Choose a window that matches your typical user conversion cycle. Short-cycle products, such as casual games or e-commerce apps, may use 7-day windows. Higher-consideration products may warrant 14 to 30 days.

2. Select an attribution logic. Decide whether credit within the window is assigned using last-touch, first-touch, or multi-touch rules. Last-touch attribution is most common for temporary attribution setups because it is straightforward to interpret.

3. Configure the window in your MMP. Platforms like Airbridge allow you to set click-through and view-through attribution windows independently. Apply these settings at the campaign or channel level to ensure consistent measurement.

4. Align windows across channels. If you run campaigns across paid social, display, and search simultaneously, ensure each channel uses a compatible window length. Mismatched windows can cause double-counting or gaps in attribution.

5. Establish a comparison baseline. Before running a new campaign, record performance data from previous campaigns using the same window length. This baseline makes it possible to evaluate whether the new campaign produced a genuine improvement.

6. Monitor and adjust. Review attribution data during the campaign window and after it closes. If conversions are clustering at the edge of the window, this may indicate that the window is too short for your users' decision cycle. Adjust for future campaigns accordingly.
