# Cross-Subscriptions

> Measure how fans from a campaign spend on other creators in your agency

A fan acquired through one creator's campaign may later subscribe to other creators in the same agency. Cross metrics group that later activity with the original attributed cohort so you can see the broader agency result.

Tracking Links adds a dedicated group of **Cross** columns that attribute those secondary subscriptions back to the campaign that originally brought the fan in.

## When to use cross metrics

* You run a general agency-brand ad that should drive traffic to multiple creators
* You want to decide which campaigns are actually most profitable once agency-wide revenue is counted
* You need to justify a budget to an advertiser by showing the full picture, not just the model they invested in

## The Cross columns

| Column            | Formula                                                              | What it tells you                                                    |
| ----------------- | -------------------------------------------------------------------- | -------------------------------------------------------------------- |
| **Cross Subs**    | Fans from this campaign who also subscribed to other agency creators | How much your campaign expands reach across the agency               |
| **Cross Rate**    | Cross Subs / Subs × 100                                              | Share of acquired fans who went on to subscribe to someone else      |
| **Cross Revenue** | Total net earnings those fans produced on other agency creators      | Revenue recorded for the cohort outside the primary creator          |
| **Cross/Fan**     | Cross Revenue / Cross Subs                                           | Average value of a cross-subscribed fan                              |
| **Cross/Direct**  | Cross Revenue / Revenue × 100                                        | How big cross earnings are compared to the campaign's direct revenue |

<Note>
  Cross metrics only count accessible creators in your own agency with synchronized data. They show later activity by the attributed cohort, not proof that the original ad caused every cross-subscription or purchase.
</Note>

## The Total columns

After the cross group, three Total columns combine direct and cross activity into a single number per campaign.

| Column            | Formula                                         | Use it to                                          |
| ----------------- | ----------------------------------------------- | -------------------------------------------------- |
| **Total Revenue** | Revenue + Cross Revenue                         | Compare the full earnings of a campaign            |
| **Total Profit**  | Total Revenue − Promo Cost                      | See real bottom-line profit, counting all spending |
| **Total ROI**     | (Total Revenue − Promo Cost) / Promo Cost × 100 | Decide the campaign's true return on ad spend      |

<Tip>
  A campaign with a weak direct ROI may have a strong **Total ROI** thanks to cross-model activity. Compare both numbers before cutting a channel.
</Tip>

## The Cross Subs modal

Clicking the **Cross Subs** count for any campaign opens a modal with a per-creator breakdown of where those fans went.

The modal shows:

| Column        | Meaning                                                    |
| ------------- | ---------------------------------------------------------- |
| **Model**     | The other agency creator the fan subscribed to             |
| **Subs**      | How many fans from the campaign subscribed to this creator |
| **% Subs**    | Share of total cross subs that went to this creator        |
| **Revenue**   | How much those fans spent on this creator                  |
| **% Revenue** | Share of total Cross Revenue coming from this creator      |
| **ARPS**      | Average revenue per subscriber on this creator             |

Features of the modal:

* **Search** — filter the list by creator name.
* **Sort** — click any column header.
* **Export CSV** — download the breakdown.
* **Total row** — sums the absolute counts and shows the overall ARPS.

<Tip>
  Use the modal to identify which partner creators in your agency benefit the most from your campaigns — useful for cross-promo planning and fair cost attribution.
