# Signals

> Track newly discovered Shopify stores and visible app or pixel changes.

Signals watch for useful store changes and collect matching stores in one place. Use them to find new prospects when StoreInspect discovers a store or detects a change to its visible technology stack.

## Choose what to track

| Signal type   | What it matches                                             |
| ------------- | ----------------------------------------------------------- |
| New stores    | Shopify stores newly discovered by StoreInspect.            |
| App changes   | Stores where a selected app is installed or removed.        |
| Pixel changes | Stores where a selected tracking pixel is added or removed. |

<Warning>
  A new-store match means the store is new to StoreInspect. It does not mean the business or storefront launched recently.
</Warning>

## Create a signal

<Steps>
  <Step title="Open Signals">
    Select **Signals** in the dashboard sidebar, then choose **New signal**.
  </Step>

  <Step title="Choose a signal type">
    Select New stores, App changes, or Pixel changes.
  </Step>

  <Step title="Choose the change">
    For an app or pixel signal, choose whether to track additions or removals, then select the technology.
  </Step>

  <Step title="Narrow the store scope">
    Add optional category, country, traffic, revenue, app, or pixel filters. Leave the section empty when the signal should match across all stores.
  </Step>

  <Step title="Create the signal">
    Review the choices and select **Create signal**. A new signal may already contain recent matching results.
  </Step>
</Steps>

## How store filters work

Every filter row must match the store. When one row contains several selected values, any of those values can satisfy that row.

For example, a signal with these filters:

* Category is Fashion or Beauty
* Country is United States
* Currently uses app is Klaviyo

matches a United States fashion or beauty store where StoreInspect detects Klaviyo.

<Info>
  With no store filters, any store can trigger the signal.

## Review matches

The Signals table shows the current status, match count, latest match, and store scope for every signal.

Open a signal to:

* Search and sort matching stores.
* Copy selected rows into a spreadsheet.
* Dismiss results that are not useful.
* Open **Dismissed** to review or restore dismissed results.

Dismissal changes only your result view. It does not remove the store from StoreInspect.

## Manage a signal

* **Pause:** Stop collecting new matches without deleting the signal or its existing results.
* **Resume:** Start collecting new matches again.
* **Edit:** Change the signal name, tracked technology, direction, or store filters.
* **Delete:** Permanently remove the signal and its results.

Paused signals do not count toward the active-signal limit.

## Active-signal limits

| Plan       | Active signals |
| ---------- | -------------: |
| Free       |              1 |
| Pro        |              5 |
| Business   |             20 |
| Enterprise |             50 |

If the active limit is reached, pause an existing signal, create the new signal as paused, or upgrade the plan.

## When matches appear

Signal timing depends on when StoreInspect can reliably check a storefront. Changes may not appear immediately.

StoreInspect confirms removals before reporting them to reduce false alerts caused by temporary loading problems. Failed or unavailable storefront checks do not count as confirmed removals.

Matches and new-match counts appear in the StoreInspect dashboard. Signal email notifications are not currently sent.

## Detection limits

Signals use technology that is visible on public storefront pages. Private integrations, backend-only apps, consent behavior, regional loading, and custom implementations can hide an app or pixel from detection.

<Warning>
  A missing detection does not prove that a store has never used, or no longer uses, a technology. Verify high-value prospects before using a change in outreach.
</Warning>

## If a signal has no matches

Try these checks:

1. Remove optional store filters to widen the scope.
2. Confirm that the selected app, pixel, and change direction are correct.
3. Check the Signals table to confirm that the signal is Active.
4. Allow time for StoreInspect to observe qualifying stores.
