Rank tracking

Manage Rank Tracking

Start or stop nightly keyword rank tracking for one Amazon ASIN in Launch Fast.

Field	Value
MCP tool	`rank_tracker_manage`
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.
Permission	Save research and manage rank tracking (Launch Fast tools). It is off at the start on the permission screen, so choose it when you connect.
Amazon connection	Not necessary
App view	`ui://launchfast/v2/rank-tracker`

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. It is free and does not change anything.

Inputs

Input	Required	Values	Example
`action`	Yes	`track` or `untrack`	`track`

What The Answer Contains

The next call, for example rank_tracker_lookup with the ASIN, to read the first ranks.

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`.
`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.

rank_tracker_lookup reads the ranks.
amazon_ads_targeting_performance_lookup uses tracked ranks to compare organic rank with ad spend.
