# 首次点击归因政策说明
如果最后点击（Last Click）将所有归因和佣金都给最终在转化路径中带来点击的合作伙伴，那么首次点击（First Click）则将其给到路径中最先带来点击的合作伙伴。合作伙伴通常认为这种方式不太受欢迎，而且通常不推荐。
采用首次点击归因政策时，在转化路径中促成首次点击的合作伙伴将获得 100% 的归因，通常还会获得该转化的全部佣金。不过，获得全部归因可能取决于你的 [参与奖金](/brand/zh/what-would-you-like-to-learn-about/platform-features/contracts-and-template-terms/template-terms/payout-adjustments/participation-bonuses-explained.md) 设置。

**兼容性说明：** 不同于 [最后加购](/brand/zh/what-would-you-like-to-learn-about/platform-features/tracking/credit-policies/last-to-cart-credit-policy-explained.md), 首次点击不需要手动 [通用跟踪标签（UTT）](/brand/zh/what-would-you-like-to-learn-about/platform-features/tracking/javascript-tag-tracking/tracking-with-universal-tracking-tag-utt.md) `trackCart` 实现。如果你使用的是应用或插件集成，包括 Shopify、WooCommerce 或 BigCommerce，请使用不需要 `trackCart`.
{% endhint %}
首次点击政策与其他政策之间的一个重大区别是需要设置回溯窗口。该窗口设置了 impact.com 应该向前回溯多远来查找转化路径中的首次点击。由于转化路径会在 [行为锁定窗口](/brand/zh/what-would-you-like-to-learn-about/platform-features/actions-and-payouts/understand-the-action-life-cycle-and-finance.md) 开始时（即当某个转化，例如一笔销售，被跟踪时），回溯窗口决定 impact.com 应该向前追溯多远来寻找引荐合作伙伴。
例如，如果回溯窗口设为 90 天，那么只会从转化发生时向前回溯 90 天。该窗口中最早带来点击的合作伙伴将获得该转化的归因，即使实际转化路径花费的时间超过 90 天也是如此。
示例场景
例如，我们来看看 Duff Inc. 的业务。他们因几个不同原因决定升级到 Professional 版本，并且特别希望将归因逻辑切换为首次点击归因政策。
Duff Inc. 将回溯窗口定为 45 天，因为他们在使用 Last Click 时，所有转化路径都需要这么长时间才会完成转化。他们还决定将首次点击政策置于 Last Click 之上优先级。最后，所有合作伙伴都将按照首次点击归因政策获得归因。
不过，不知为何，他们的转化路径看起来与使用 Last Click 时完全一样。客户总是通过商品博客的横幅广告添加眼镜，在点击赞助搜索结果后添加 s 品牌，然后在点击赞助的 Instagram 帖子后完成购买。然而，自从切换之后，商品博客一直拿下所有转化，因为是他们在转化路径中促成了首次点击。
#### 我该如何申请此归因政策？
请联系你的 CSM（或 [联系支持团队](https://app.impact.com/support/portal.ihtml?createTicket=true)）讨论启用首次点击归因政策。你需要说明为什么想使用该政策、是否所有合作伙伴都采用首次点击（如果不是，在同一用户旅程中存在多个政策时，应以哪种政策优先），以及你是否已经考虑过回溯窗口。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://help.impact.com/brand/zh/what-would-you-like-to-learn-about/platform-features/tracking/credit-policies/first-click-credit-policy-explained.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
