Unique value limitations for Product_type attribute?

Visitor ✭ ✭ ✭

Within our Google shopping feeds we often submit child & parent skus to google because our campaigns get more traction than if we just submitted parent skus. The problem is that we end up with campaigns containing up to 50k skus or ID's within Adwords. Optimization would be streamlined if I could subdivide campaigns/ad groups/product groups on the parent sku level while maintaining the robust feed data of all skus. I thought about putting parent sku in custom label columns and subdividing by that, but there's a 1000 limit per custom label. Most of our clients have up to 5-7K unique parent skus so that's not gonna work. The only other attribute that I can subdivide by in Adwords is product_type. So I would essentially put the parent sku/item_group_id in the product type attribute in the feed, then subdivide by that in adwords. That way, if I changed a bid for 1 parent sku it would keep the bid the same across the child skus, yet google would still crawl the whole feed to serve the best line item as it relates to a search query. Also, my adwords accounts would have 5-7K biddable items in stead of 20-50K. Do you know if there is a limit to unique values for product_type... or any other reason this might not work? If google would allow item_group_id to have all the same capabilities as ID within Adwords, then that would solve it. Unfortunately that's not the case today.

Thanks,
Seth

the product_type attribute is limited to 750 characters --
a product_type value must use standard > breadcrumbs
and should categorize the physical item.

to subdivide items into groups, the product_type
value per-item should use a hierarchical taxonomy
across all items submitted.

if multiple product_type values are submitted for an item,
only the first value can be used in a shopping-campaign.

otherwise, there are no per-feed limits, unlilke custom-labels --
which are designed mainly for very limited abstract groupings,
such as specific sale, seasonal, or low-margin sets of items.

as an aside, for variant items, the parent-sku can certainly be used
as the item_group_id for all items within a variant-group -- however,
submitting the parent as a listing is generally a policy violation and
grounds for a disapproval, at any time.

Thanks for your feedback. There is a limit for custom labels. You can only have 1000 unique values per custom label. You do not need to include > breadcrumb taxonomy in the product type attribute if you don't want to. You can put whatever you want in that attribute. I realize what the product type and custom label attributes were designed for. My solution is a work-around to bypass the limitations of Google Shopping campaigns. Custom labels are not an option because of the 1000 limit. I'm wondering if anyone knows if there's such a limit on the product_type attribute. Also, you can submit the parent as a listing. That's not a violation. The point is you cannot subdivide by item_group_id. Only ID, product_type, custom label, & category. Obviously id & custom label are not an option for my purposes. And it would be unwise to use category for this b/c it's an attribute that Google crawls when query parsing. So that leaves me with product type.

first, you're welcome.

only custom-labels have both character and unique-value limits.

as was indicated, product_type only has a character limit --
there is no unique-value limit as there is with custom-labels.

product_type does require standard > breadcrumbs and a hierarchy
if the values are used for subdivisions within a shopping-campaign --
but there is no requirement to use product_type for this purpose.

product_type does have requirements per the specifications; but,
almost anything can be used as a value, within those specifications --
not adhering to the specifications can trigger a disapproval.

product_type may also be indexed for search and used for queries and
similar purposes such as categorizing items within google-shopping --
at google's discretion -- in addition to google_product_category.

using product_type as a de facto id is rather up to you --
other than character limits and only the first value being
seen within a shopping-campaign, there are no similar
limits to custom-labels so, product_type could be used
as an id; however, as was a stated, this is a workaround,
not the attribute's documented intent so, unintended
consequences may surface later.

there may be a better alternative to attain the the same outcome --
however, forum-members cannot look into feeds or accounts; but,
a support-specialist at google may be contacted for guidance.

@Celebird, As per Google's requirement it states that you can use your own categorization. There is no mention about needing to use breadcrumbs.

"You must use " > " as a separator, including a space before and after the symbol."

 

as was indicated, only if the values are used for subdivisions

within a shopping-campaign are the breadcrumbs required --

there is no requirement to use subdivisions.

 

if the values are flatted, without breadcrumbs or without any

hierarchy, so will be the (potential) product-group divisions

or lack-thereof when using the product_type attribute.

 

the main issue was concerned with (unique value) limits and

using a product_type as a flat value for a de facto id value --

there are no such limits and an id could be used as a value --

but this is not the intended purpose of the attribute and may

therefore effect overall quality.

Hi, the general idea of a breadcrumb is a specific category on your web pages. I wanted to separate the idea of the common knowledge of the word breadcrumb, compared to using a > separator.

Just want to avoid merchants thinking what your trying to say.

There are allot of merchants asking these questions and simply by saying breadcrumb will make them assume it is the categorization that is used on pages. While it is actually any categorization with each division separated by a >

The categorization can also be an offline grouping system.

Hope you understand what I'm trying to say now Smiley Happy

breadcrumbs in this reply was used specifically
as google defines for the attribute -- to subdivide
product-groups based on a category hierarchy;
google has strict rules when using breadcrumbs
for this purpose within a shopping-campaign.

without proper breadcrumbs and a category hierarchy,
product_type cannot be used properly to subdivide items
into groups within a shopping-campaign, only as flatted
selections, much like the id attribute -- which is what was
wanted in this particular case.

normally, the (product_type) breadcrumbs are used to

both (a) help google categorize the physical item and

(b) subdivide product-groups in a shopping-campaign

to assign bids to subsets of (similar) items.

google specifically recommends using full breadcrumbs in this context.

the hierarchy is typically taken directly from a website --
but this is not required with respect to product_type.

Thanks Celebird. Sounds like I could use product type, but I agree with you - undesirable affects could surface later. It's not ideal, but unfortunately shopping campaign limitations force these kinds of workarounds.

One thing I want to touch on: When I went to Google in NYC for a Shopping workshop, they said that product type was not crawled by Google when query parsing. I had my doubts, but eventually bought in. You say Google does look at that attribute in relation to the ad serving process. Could you confirm/elaborate?

first, you're welcome.

as to crawling, the emphasis would be on may and similar purposes.

for some types of items and target-countries
google_product_category is only recommended --
not a required attribute; product_type may then
help serve a similar purpose.

google is constantly experimenting with features and how items
are displayed, indexed for, and grouped within, google-shopping.
