This is a solution to be used by shopping Customers (CSS, GCS). It consists of a script (js) to be run in Google Ads Scripts. It uses Google Ads API (the previous version used AdWords API, which is deprecated).

• Merchant Center Sub Account (not MCA)
• A Spreadsheet with 2 columns (for supplemental feed).
• A free custom Label (otherwise existing values will be replaced with the values from supplemental feed.)

NOTE: MCAs require a combination of various components (CF, BQ, GCS) to use supplemental feeds - which won't work with this - so a solution is WIP.

Here is a simplified overview of the steps. A detailed step by step description can be found in the deck below. * Implementation Deck

1. Create a new spreadsheet and name columns 1 and 2 (cells A1 and B1) 'id' and 'custom_label_0-4' (eg. custom_label_4).
2. Create a new Google Ads Script (Tools settings > Bulk Actions > Scripts).
3. Copy the script content and paste in the newly created Google Ads Script.
4. REPLACE (at least) the variables for: * CUSTOM_LABEL_NR, * SPREADSHEET_URL,
5. Check other variables that you may want to change: * THRESHOLD, USE_CAMPAIGN_FILTER, FILTER_CAMPAIGN_NAME, PRODUCT_ID_CAPITALISED, TIME_DURATION, and/or COUNT_LIMIT.
6. Authorize your script to run in Google Ads Account. 7. Run the script (you can also hit preview) and check for potential errors in the execution logs or in your spreadsheet.
7. Set a frequency to run your script automatically. 9. Create a supplemental feed in your Google Merchant Center account, using the spreadsheet created above.
8. Create a new Low Volume SKU campaign and use inventory filters to target items via the custom label.

Note: It is important that both schedules (from script and supplemental feed) are timed correctly so that new labeled product are properly picked up.

1. If capitalised offer_ids are used - script must be adjusted based on the naming convention as Ads API converting offer_id values to lowercase which will cause mismatch during supplemental feed processing. Please use PRODUCT_ID_CAPITALISED flag to convert offer_id's to upper case.
