Hello,

I don't use that form to feed GMC, but I know they have a subscription plan so support is included.

Check in Merchant Center that the import is periodic, even every night for example. Maybe the incorrect availability depends on that.

If the product has gtin code, yes you need to add it. if you don't have it use the existing identifier attribute [identifier_exists] to indicate that there are no identifier product codes (UPI) available for the product. Identifier product codes are submitted using the GTIN [gtin], MPN [mpn], and brand [brand] attributes.

You should add GTIN in Prestashop product page, you can do it by creating a csv file and then importing it into Prestashop.

Are those clicked on, do you have reactions?

Most people leave the merchant center due to expensive and ineffective. Especially the DACH crowd.

Here's how you can address the issues with the Google Marketing by PrestaShop module for Google Merchant Center:

1. Syncing Stock Status Correctly

Why Products Out of Stock on Your Website Appear In-Stock in Google Merchant Center

This often happens because the product feed generated by the module isn't updating the availability status correctly or the Merchant Center isn't re-fetching the feed frequently.

Solution Steps

Verify Stock Settings in PrestaShop Module:

Go to the Google Marketing module configuration.

Ensure that the stock synchronization option is enabled.

Check that the availability attribute in the feed is mapped to your product stock status:

"in stock" when quantity > 0.

"out of stock" when quantity = 0.

Update the Feed Manually:

Regenerate the feed in the module.

Go to Google Merchant Center > Products > Feeds and ensure that the feed is re-fetched.

Automate Feed Updates:

Set up a cron job to regenerate the product feed regularly:

Go to Advanced Parameters > Cron Jobs in PrestaShop.

Add a cron job for the feed generation URL provided by the Google Marketing module.

Ensure that Merchant Center fetches the feed daily:

Go to Merchant Center > Products > Feeds > Fetch Schedule and set a daily fetch.

Check Merchant Center Diagnostics:

After updating, check for warnings or errors related to stock attributes in Diagnostics.

2. Adding GTIN in Bulk

Why GTIN is Critical

Google Merchant Center requires GTINs (Global Trade Item Numbers) for most branded products. Without it, products are likely to be rejected or limited in visibility.

Solution Steps

Export Products to CSV:

Go to Catalog > Products in your PrestaShop back office.

Export your product list by filtering necessary fields like Product Name, Reference, and Supplier.

Add GTINs to the Exported File:

Look up the GTINs for your products:

Manufacturer or supplier documentation.

Online databases for GTINs (e.g., GS1 or UPC Lookup).

Populate the GTIN column in the CSV.

Import GTINs Back to PrestaShop:

Add a custom field for GTIN in PrestaShop:

Go to Catalog > Products > Attributes & Features and create a new feature for GTIN.

Re-import the updated CSV:

Go to Advanced Parameters > Import.

Map the GTIN field to the newly created GTIN attribute.

Verify GTIN Sync in Google Marketing Module:

Check the Google Marketing module settings to ensure that the GTIN attribute is included in the feed.

Regenerate the feed and re-upload it to Merchant Center.
