Feed Manager (Facebook & Google feeds – 3 feeds) – This extension provides Google and Facebook product feeds. It is the only extension that also provides a product feed for dynamic remarketing via analytics, which is currently the only dynamic remarketing option in countries not supported by the Google Merchant Center. It supports product feeds for Google Merchant Center, Google Business Data, and Facebook’s new product catalog. All channels can be found in Extensions → Channels, additional settings for Google Mall can be found in Catalog → Categories [data] to customize Google taxonomy and in Product Catalog → Products [edit ] (Google Merchant Center) for clothes and flowers.
If you want to use a facebook product feed, it is recommended that you assign the appropriate taxonomy to the google category in all your categories. Without a Google taxonomy, facebook will complain about missing categories, but the feed will work, so it’s optional.
This extension supports creating feeds for super large stores where the upload file size can reach several GB (google mall supports 4GB and facebook 8GB). You can set up a cron job, create a product feed file, and not directly download the feed, this is optional but I recommend it for very slow and large stores.
