item group id and parent skus

Visitor ✭ ✭ ✭

When creating parent and child skus on feeds for say Amazon a line item for parent sku with required attributes has to be included, I can't seem to figure out how to create a parent sku with variants with a CSV. feed upload. I have all my skus that are color and size variants with the same item group id set for each, and all got approved and are searchable, however if I go to Google shopping and search it doesn't have them grouped it has each size and color as separate items with many missing. Does google take all skus with that same "item group id" and automatically group them based on differing size and color, and it just takes some time and I am being impatient, or does a parent sku have to be created as well and if so how, I tried to do this and it errored saying size was missing which a parent sku can't have a size, that would defeat the purpose of a parent sku

for a products-feed for product-listing-ads, all items within the
variant-group must have the same, identical, item_group_id value --
each variant-group must have a unique item_group_id and every
item submitted must have a unique id value that never changes.

a separate parent item of a variant group cannot and should not be submitted --
but, a parent-sku might be used for the group's item_group_id as a best-practice.

 

also, be certain each title in the variant-group has at least a common title --
adding variant information to each group's title is an optional best-practice.


if there is a change to a feed google may sometimes take 24-72 hours
or so to process the feed, crawl all the items, assign a bid and quality,
and reflect the changes within the auction results.

 

also, be certain all items submitted have required, proper, and valid

global-trade-data (mpn, brand, gtin) values as required by google for

the type of item, as assigned by the manufacturer, to the exact item

being sold -- or, set identifier_exists to FALSE


however, there is currently no way to force how google displays, groups,
or formats, any submitted data for any particular search-term or result --
google is constantly experimenting with formats, groupings, and results.

also, the only currently documented supported feed
file formats are .txt tab-delimited and google-xml.

Thanks, definitely useful. So when you say "a parent-sku might be used as the group's item_group_id as a best-practice" does that mean one of the skus (i.e. Running shoe color x size y) can essentially be assigned as the "parent-sku" and all other color and size variations will us that item id as their "item_group_id"? Also, given this should the title for each item be general, not specific? I.e. title for each item I had size and color in the title, is this redundant since both are already specified and the title of each should just be the Brand and model clear and simple? A lot of my searches from yesterday where today appearing as the full title with size and color in the title and no variants when selected so just trying to figure out how to correct that (all items have full info, mpn, brand, and gtin, items themselves all got approved they just didn't seem to be grouping despite identical item_group_id values for each items I wanted groups, perhaps I was just too haste in trying to fix something that google just needed more time to process, is that sound like that might be the case?

first, you're welcome.

(1) yes, just about any value may be used for item_group_id --
as long as, all items in the group have the same item_group_id

and the value is unique to that variant-group.

using one of the sku or parent-sku as the item_group_id are both common
practices -- and is used as one example in the above cited reference:
https://support.google.com/merchants/answer/1347943

(2) the title is (at least) required to be common among all variants --
a part of the title may be unique and is one recommended practice:
https://support.google.com/merchants/answer/188494#title

(3) results in the auctions are based on the bid and quality factors.

yes, if the variants are newly submitted, the system may
take awhile to process and understand the item details.

to emphasize again, there is currently no way for merchants to
force any items or variant-items to be grouped or not grouped.

a lot of what is grouped or not grouped depends on how user's search,
what features are selected or not selected, a user's search history, the
type of physical item, global-trade-data, variant attributes and all data
submitted, and many many other factors known only to google.

mainly, google indicates the policies and rules of how (variant) items must
be submitted; if (variant) items are not submitted as google specifies, that
simply risks disapproval or suspension from the program, at any time --

or items eventually removed from the auctions due to low quality.

however, currently, google decides how items (ads) might be grouped,
formatted, or displayed, for all product-listing-ad auction results --
there are currently no concepts of forcing-groupings, wanting-groups,
or fixing-groups, with respect to auction results.

also, the better methods to verify if items are winning in the auctions are to
check the impression and click statistics within the account or by using the
ad-preview-tool; searching directly (within google-shopping) for the same
similar items over and over again -- especially without any positive action --
may indicate to the system that the ads are not wanted and all associated
items may then be removed from those auctions.

 

as a slight aside, csv is not documented as a supported file format so
there is no guarantee such a file will be processed properly -- always
verify the individual results within the products-tab by clicking on the
item's title and check the diagnostics-tab's for any issues by clicking
on the account, feeds, and items blue-boxes.
