# Auto-merging campaigns by ID If you're frequently updating the names of your campaigns, we recommend enabling the **"Auto-merge Campaigns by ID"** feature in your settings. This option allows us to look at the historical data for each integration and reprocess it, ensuring that older campaign names are updated based on their unique campaign IDs. We sync that data weekly. This functionality is currently supported for **Google Ads**, **LinkedIn Ads**, and **Reddit Ads**. **Note:** This does not impact LinkedIn **goal impressions**, as they are retrieved via a separate API endpoint. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
