# Drift Detection

Alerts you when page content was changed outside Smart Pages (e.g., in Shopify theme editor).

## What causes drift

* Someone edits the page in the Shopify theme editor
* A theme update modifies templates
* Another app changes page content

## Resolving drift

The drift banner offers three options:

### Keep Smart Pages version

Overwrites theme with Smart Pages' saved version. Use when the theme edit was accidental.

### Import changes

Pulls theme changes into Smart Pages. Use when the theme edit was intentional.

### View diff

Side-by-side comparison to decide which version to keep.

{% hint style="warning" %}
Use **View diff** first if unsure which version is correct.
{% endhint %}
