Feed editor - Basic product data
This section specify how the basic data of the item in Google Merchant Center is generated, including the item ID, product title and product description.
With expressions, you are free to customize these attribute to meet the marketing requirements. For example, you can add arbitrary text to product titles, or pull the product options into the feed for a description like "Styles: Short-sleeve, Long-sleeve; Colors: Red, Blue; Sizes: Small, Medium", which is recommended for better SEO.
You may also change the main image of product that will show in the shopping ads on this tab. You can customize the main image in a variety of ways, like using a variant image, the first product image, the second product image, and so on, or selecting an image from metafields.
Given how images are important in e-commerce these days, the app allow extensive customization of additional images either manually in product level feed settings, or with following feed settings
Number of additional images
Set this value to 0 will skip submission of additional images.
Additional images selection
Shopify only allow a variant to be assigned only 1 image. This image will typically serve as the main image of the feed item. There is no official ways to assign more than 1 image to a variant.
By default, the app will select the "additional" images for a variant from the product gallery, which meet these conditions:
1/ Not assigned to any variants, or assigned to only the variant in question.
2/ Different from the main image
This behavior can be overridden in several ways
This allow you to specify additional images by using expressions. Available tokens include image variant/product metafields (metafields that contain image or image list).
Variant image affinity
Default image selection might not work for all use-cases. For example, shops can use customization or apps to have more images per variants (check out here, for example). In these customization or apps, there must be a way to link an image to a variant (affinity), and this is mostly done via the image alt text or the image name (which then become part of the image url). For example, an image may have alt text "Red" to indicate that it "belongs" to the red variant of a shirt. With some landing page theme modification, this will allow the right images to show up when a variant is selected.These linking between variant and images need to reflect in product feeds to. Variant image affinity allow to add an expression, when evaluated to true indicate linking between an image and its variant.
The feature in action:
1/ Pick images that have color built in to their names (or URLs)
'Image url' ~= 'Option "color"'
2/ Pick images that have the alt text set to a variant size
'Image alt text' ~= 'Option "size"'
3/ Skip a particular image that reported with Google violation
'Image alt text' != "nudity"
The following expression indicate that if the alt text of the image contains the color of the variant, then the variant is linked to the image. Other tokens for the expression include image url, different variant options, attributes, and metafields.
Edit image and additional images in product level feed settings
Please note that both main and additional images can be manually customized (and assigned) to variants using product level feed settings, which take precedence over the variant image affinity expression.
Here you can do some advanced price modifications for all your pricing needs.
Similar to prices, product availability can also be customized to the requirements of the feed
