| Behavior          | Makes a change in your Launch Fast account. Marked destructive, because untracking stops tracking, so your AI app may ask you to confirm before it runs. Tracking the ASIN again brings its history back. It does not change your Amazon account. |
| Cost              | Free. Each tracked ASIN uses one rank tracking slot of your plan.                                                                                                                                                                                 |

## What It Does

`rank_tracker_manage` starts or stops rank tracking for one Amazon US ASIN. The ASIN can be your own product or a competitor's. Launch Fast refreshes the keyword ranks of tracked ASINs each night.

* **Track:** the ASIN uses one slot. The first ranks arrive when the first capture finishes, usually in a few minutes.
* **Untrack:** the slot becomes free. Launch Fast keeps the rank history. If you track the ASIN again, the history comes back.

The Growth plan includes 10 slots. The Scale plan includes 15 slots. If you track more ASINs than your plan includes, for example after a change to a smaller plan, the newest ones pause.

## When To Use It

Use `rank_tracker_manage` only when you ask to track or untrack an ASIN. To read ranks, use [`rank_tracker_lookup`](https://docs.launchfastlegacyx.com/mcp/research/rank-tracker). It is free and does not change anything.

## Inputs

| Input    | Required | Values                                          | Example      |
| -------- | -------- | ----------------------------------------------- | ------------ |
| `action` | Yes      | `track` or `untrack`                            | `track`      |
| `asin`   | Yes      | An ASIN or its Amazon link, in all letter cases | `B0C1EXAMPL` |

## What The Answer Contains

* The status: `tracked`, `already tracked`, or `untracked`.
* The slots that you use, out of the slots in your plan.
* The next call, for example `rank_tracker_lookup` with the ASIN, to read the first ranks.

## Example Prompts

```text
Track B0C1EXAMPL in Launch Fast Rank Tracker.
```

```text
Stop tracking B0D2EXAMPL. I do not sell it anymore.
```

## Common Errors

| Error           | What it means                                     | What to do                                                                         |
| --------------- | ------------------------------------------------- | ---------------------------------------------------------------------------------- |
| `cap_reached`   | You track as many ASINs as your plan includes.    | Untrack one ASIN to track another.                                                 |
| `not_found`     | You asked to untrack an ASIN that is not tracked. | List tracked ASINs with [`rank_tracker_lookup`](https://docs.launchfastlegacyx.com/mcp/research/rank-tracker).       |
| `invalid_input` | The `action` or ASIN is not valid.                | Use `track` or `untrack`, and a 10-character ASIN.                                 |
| `plan_required` | Your plan does not include rank tracking.         | Check your plan on the [usage page](https://launchfastlegacyx.com/settings/usage). |
