One of the common errors you might encounter in Google Merchant Center is the "Invalid Value" error. This error occurs when one or more attributes in your product data contain values that do not adhere to Google's guidelines. This is in the form of an unsupported value or missing entirely.
To fix the "Invalid Value" error, carefully review your product data. Ensure that all attribute values follow Google's specifications. This may include formatting requirements, character limits, and accepted values for specific attributes.
If you have a "color" attribute, make sure the values match accepted color names or codes, such as "Red", not "#FF0000."
For size attributes, use standard size labels like "Small," "Medium," and "Large", or “S”, “M”, and “L”. Keep it consistent, and don’t mix your formatting such as “Small”, “M”, and “Large”.
Ensure that prices are in the correct format, using the appropriate currency symbol and decimal separator.
