# Listing errors

> What it means when listings fail during the daily synchronization and how to make them measurable again.

This warning appears when one or more listings failed during the daily [synchronization](/docs/en/guide/automation/syncs). As a result, those listings are missing current price data.

## Cause

A synchronization fails when PricePirate can no longer measure the listing on the marketplace. Common reasons are:

* The marketplace listing was removed, hidden, or moved.
* The marketplace changed the product page, so the connection no longer resolves.
* A temporary fetch error on the marketplace.

### On Idealo

On Idealo, these additional cases occur:

* Idealo removed the product page because too few merchants offer the product.
* The product has no dedicated product page on Idealo — some listings simply do not exist on every marketplace.

<Warning>
  PricePirate can only reliably match offers from a **product page**. The Idealo offer overview — the grid, or the search results — is **not** a product page. Always connect the product page, not the overview or search results page.
</Warning>

## Solution

<Steps>
  <Step title="Open the affected listings">
    In the notification, click **Fix problem**. You see the listings whose last synchronization failed.
  </Step>

  <Step title="Review the listing">
    Open the marketplace listing and check whether the offer page still exists and shows the correct product.
  </Step>

  <Step title="Reconnect or remove">
    Reconnect the product to the correct listing through [Connect listings](/docs/en/guide/catalog/connect-listings). On Idealo, matching by EAN/GTIN is generally reliable; if it does not find the right match, paste the Idealo **product page** URL directly into the search field. If the offer no longer exists, disconnect it or deactivate the product.
  </Step>

  <Step title="Connect on another marketplace">
    If the listing does not exist on this marketplace, you can connect the product on another marketplace. This requires a plan that includes **multiple markets**; you then set up the markets in the [Settings](/docs/en/guide/account/settings) under **Markets**.
  </Step>

  <Step title="Check the connection">
    A correctly connected listing shows a checkmark and produces snapshots again on the next synchronization. You can see whether new snapshots are being created in the product's metrics.
  </Step>
</Steps>
