eBay AI Summaries In Facebook Marketplace Partner Listings Could Increase INAD Claims
I posted this in another thread about the eBay Facebook Marketplace partnership but figured it was important enough for its own post so sellers are aware - if your items are being cross-posted by eBay to Facebook Marketplace, the description may include erroneous info added in by eBay.AI
A seller sent me screenshots of an eBay Facebook Marketplace Partner listing they saw live in the wild - in this example, eBay is using AI to provide a summary of the description and it has added in a sentence at the beginning about vintage racing decals that does not appear anywhere in the seller provided info for this actual listing.
This seller does have a few other listings in their store for racing decals, which is likely where the AI is drawing that info from, but they are not listed as vintage and either way, that info does not belong to this listing and shouldn't be represented that way in the Facebook Marketplace listing.
eBay has promised sellers that since the transaction will still be happening completely within the eBay ecosystem, they will still receive the same protections as any transaction directly on the site itself.
But it's not clear if eBay will provide protections in cases where their AI adds incorrect info to a summary shown on a different site without the knowledge of the seller - and given how eBay's User Agreement and other policies handle the issue of responsibility for AI generated content, I wouldn't hold my breath that eBay will protect sellers from INADs in these instances.
eBay has auto-opted all listings into this feature - while it's not guaranteed your listings will be shown on Facebook, they are eligible to appear there unless/until you actively opt out.
For anyone who doesn't want to take the risk that eBay's AI summary might result in an Item Not As Described claim, you can contact eBay to opt out:

·1 year agoThey did the same sort of thing when ebay was trying to push everyone into using the 'product pages.
At one point I had a listing for ONE doll showing on the product page (along with others) under a totally different title to mine claiming it was a 'set of 2'.
I also came across product pages with seller listings for items in a pack of 6 under the title for a pack of 12.

OP1 year ago@jasoheat_0 did you get confirmation from eBay that your opt out from having your listings shown on Facebook Marketplace was successful?
If so, any pointers you can share for @pls-consignments and others who aren't having any luck opting out?

·1 year agoSo what is the ACTUAL channel to opt out? The links thus far just dump you on a page in the help section and you have to try and navigate the chatbot. I typed in "opt out of facebook crossposting" and just got the error message "Sorry, I didn't quite get that. Please try asking again in a different way."
What are the keywords/buzzwords to use in order to get past their AI to opt out of their AI????
eBay's help system is complete garbage.

·1 year agoI NEVER Buy anything from seller that use AI descriptions! That is SOOOOOOOO LAZY and AI descriptions tell you ABSOLUTLY NOTHING! Here's EVERY AI description ever written. "This item is the Greatest - it's a must have - you'll be the talk of the town"
valueaddedresource
OP1 year ago@iabootman and that is just one of the many problems with this situation.
These sellers are not intentionally choosing to display AI created description summaries and in fact in many cases may not even be aware that eBay is doing this - which means they also may not even be aware if they are losing potential purchases from buyers like you who are turned off by AI descriptions.
valueaddedresource
OP1 year agoJust an update for @a_c_green and anyone who was following this thread - @mamacassidy has provided screenshots showing that eBay is also using explicitly labeled eBay.AI description summaries for some items within the eBay app experience as well.

·1 year ago@valueaddedresource AI is the shiny new thing, but this is just so wrong.
valueaddedresource
OP1 year ago@my-cottage-books-and-antiques absolutely agree that doing this as an undisclosed test with no opt out is just wrong on so many levels.
I understand AI is the shiny new thing and eBay feels the same pressure other companies are under from their investors to shove it into everything but - have some respect for your seller customers, make an announcement about it, allow those who are interested in being guinea pigs to voluntarily sign up and do not under any circumstances automatically opt sellers in with no warning, no way to even know which listings it applies to/when, and no way to opt out.
I can see this kind of behavior coming back to bite eBay big time and honestly I hope it does - German data privacy regulators are already questioning the section about AI training on user data in the recent privacy policy update and say they've received a lot of complaints already, so hopefully that might give eBay some incentive to rethink what they are doing and actually live up to those "responsible AI principals" they keep talking about.
a_c_green
·1 year agoUnfortunately this has been Standard Operating Procedure with eBay for, what, decades now: they simply do not communicate, seemingly as a matter of policy -- not even with each other.
Whenever something significant is rolled out, it may get a press-release posting from a group alias that never answers follow-up questions. CS phone reps never have more information, and too often have to have the new development explained to them by the caller.
As I've said on many occasions before, there is never anyone who stands up and says, "This is my idea and this is why I think it's a good thing." No one wants to take responsibility for their changes and no one wants to talk about them. The community group representatives here will always relay questions to the assorted "teams" within the company, but they are roundly ignored and actual answers (or dialogue) never appear.
In particular, technical questions or reports needing bug fixes tend to languish with no actual response. (Browse the Technical Issues group and see how many threads actually show the little eBay logo denoting a response from the company.) As someone with decades of Tech Support experience, it still amazes me that a company this dysfunctional can limp along as it does. It could be so much better.
valueaddedresource
OP1 year ago@a_c_green that sounds a lot like this discussion from 2023 about the way that eBay sometimes hides descriptions in the app behind a link and sometimes not - in fact in that discussion it was even initially thought that eBay was favoring listings using the AI description generator.
The final "answer" we came to back then was that it was influenced by the use of custom html and that sellers could increase the chances of not having their description hidden by just using plain text.
https://community.ebay.com/t5/Selling/interesting-ebay-app-hides-seller-description-but-shows-AI/td-p/33937449/highlight/true
If that's what you're talking about, I don't believe those are eBay.AI generated summaries but I could be wrong.
a_c_green
·1 year agoIt's possible that they are not AI-generated, as some of the phrases lifted out for that "summary" are stuck together into incomplete sentences, with no attempt at fixing the grammar, which is (ironically) one way that AI-generated text is so easy to identify: it's grammatically perfect.
I have to wonder, then, about what logic is being used to pull this sentence vs. that sentence out of a much larger paragraph. I don't use custom HTML at all; the most I'll do are bulleted lists.
roccotacodad54
·1 year agoIf it's the same AI they use now on Ebay for listings sometimes.
Duck and be ready for "Item Not As Described" claims.
valueaddedresource
OP1 year ago@roccotacodad54 have you seen non-seller generated AI summaries like this on eBay as well? I'd definitely be interested in screenshots or more details if so!
Or do you just mean the AI description option that sellers can choose to use when creating a listing?
a_c_green
·1 year agoNot speaking for @roccotacodad54 here, but in my case, it's the former. When in the mobile app, where eBay stuffs your full description into an off-page link, they occasionally concoct a summary description ("Item description from the seller"), maybe a paragraph or so, and use that on the main listing screen. If looking at my own listings there, I would see that "summary" put together from seemingly random phrases which the algorithm thought were relevant, but did not always make sense, and occasionally seemed to go completely wrong, like the famous "Thou shalt commit adultery" commandment typo.
One note I should add here: in scrolling through a bunch of my own listings, I could only get that summary description to appear in one listing of mine, the first one I chose, and all the others after that (found via clicking on the Seller's Other Items link) would not come up with a summary at all; the entire description was hidden behind a "See full description" link.
It appears that when you pull up a fresh list of search results, the algorithm will attempt to do a summary of the description on the first listing you select, but not on any of the subsequent ones. It looks like some kind of an internal flag is being set to indicate that a summary description was created, but that flag does not get reset (i.e. cleared) unless the entire current list of results is replaced by a fresh search. (Again, this is all concerning the mobile app, not the desktop view.)
valueaddedresource
OP1 year ago@a_c_green - interesting, thanks! Do they explicitly label it as an eBay.AI summary like they do in the Facebook listings?
a_c_green
·1 year agoUmmm... (pause while I try to remember where I put my phone down)...
No, they do not. It's either there or it isn't there.
I did some more random searches and viewing, and now I cannot see any clear pattern about when the summary does or does not appear. I did notice that when the main description was entirely AI-generated glop, then the full text could also be used as the "summary" description as well, making for a rather long summary. (I wonder if there are any hidden embedded HTML tags that identify the text as AI-generated.)

·1 year agoI for one, decided to opt out of this arranged marriage for this very concern. Arranged marriages will always require time to work out conflicts, especially when AI is the 3-fold cord. This is way too early and risky for my business, especially now.
Side note.... when I contacted CS to opt out, the rep had no idea what I was talking about. I literally had to send her eBay's own announcement links. Once received, she immediately referred me to a supervisor, who said the "opt out" email will be sent to me within 72-hrs. Can't wait to see it. 😶

valueaddedresource
OP1 year ago@ekmadonna if you haven't opted out, than all of your listings could potentially be cross posted to FB, but that doesn't necessarily mean they are being cross posted, if that makes sense.
eBay has said there is nothing sellers need to do for their listings to be eligible and that they will simply send listings from a variety of categories to Facebook based on user interest, shopping trends, and listing quality.
More info here:

And yes, if you do not want the possibility that some of your listings may be shown on Facebook, you'll need to contact eBay to request to opt out.

·1 year agoI'd say your seller has some racing decal wording in the item specifics for the fishing lure listing
valueaddedresource
OP1 year ago@redlinear and you would be 100% wrong.
Full item specifics from the actual listing:
Also just to save time, this item is listed in Sporting Goods> Fishing > Fishing Equipment> Tackle Boxes & Bags so there is nothing confusing or wrong about the category either.
As previously stated, the seller does have other items in their store which are advertised as a "grab bag" of stickers/decals, so the most likely explanation is that the AI has picked up details from other listings, spun them into its own words and added them incorrectly to this item description.
Again, to be clear, there is absolutely nothing in the seller provided info for this specific listing which states anything what so ever about racing decals.
redlinear
·1 year ago100% isn't too bad for me ðŸ˜
Are ya sure it wasn't revised?
I mean, I only checked ONE other item, a fishing reel. And it's Department in item specifics is Unisex Adult.
valueaddedresource
OP1 year ago@redlinear I really don't understand why you are so insistent on trying to find a way to blame the seller for something that is very clearly and obviously an eBay created issue.
But just to humor you - the revision history on this particular listing shows the only recent revisions were to the shipping terms, the price and/or to start or end a sale promotion on the item.
There are no notations in the revision history of any changes to the item specifics
The last time it shows a revision to the description was Dec 17, 2024 which was a month before the eBay Facebook partnership was even announced and it took several months more for eBay to actually start cross-posting items so again, from all available info there is and has been nothing in the seller provided details for this listing saying anything about racing decals during any time in which eBay would have been using their AI to summarize the description when cross-posting it to Facebook.
Now, since you say you looked at another one of their listings, you obviously have figured out who the seller is and can find this listing as well to review all of this so...please stop trying to blame the seller when you can clearly see for yourself exactly what is happening here.

·1 year ago@valueaddedresource
It's okay. I just saw where the other listing was a little sloppy. Probably just coincidence though.
valueaddedresource
OP1 year ago@redlinear whether some of a seller's listings are sloppy or not isn't really relevant to this discussion - even if it was sloppy (which there is no indication this one was), I would expect eBay to accurately and correctly convey the seller provided info when cross-posting to Facebook, not add their own AI slop to the mix to make it even worse.
Bottom line - eBay shouldn't be adding *anything* to the description that isn't actually present in the seller provided info on the listing, period.
redlinear
·1 year agoRacing Decals and Tackle Boxes
Now there's a little explored niche
wastingtime101
·1 year agoYeah, this isn't on the seller or how they set up their listing. Looks like something eBay needs to work out. If I were a betting man I'd say eBay has already seen this discussion and someone has flagged this to be researched.
Also - how is listing a fishing rod or reel for "unisex adults" sloppy? I mean it's not necessary to fill out that specific since it's generally assumed the product is for adults - that field is more appropriately used when it's a kid-sized fishing rod / reel so people looking for kid-sized product can filter and quickly find what they're looking for - but there's nothing incorrect or sloppy about indicating the item is for adults. Not that it's in any way related to the topic at hand. Ignore my side commentary and proceed with your Facebook / AI discussion. 😛
For what it's worth, I looked at the listing on eBay web, mobile web, & app and none of those three platforms had the AI summary so this is just a Facebook Marketplace (FBM) thing. It's new, I'm sure they'll work out the kinks pretty quickly.

Forcing AI on to others without the ability to edit/delete is a problem if AI incorrectly describes something in a listing.
chevymontecarlo88
·1 year agoMaybe i am not understanding how AI descriptions work. Is it not the seller's responsibility to make sure their listing is correct if they choose to use AI to describe their own listing? If you use a shipping calculator incorrectly, aren't you still responsible for the correct shipping charges?
lacemaker3
·1 year ago@chevymontecarlo88,
As @valueaddedresource explained, the AI was added to the post on FB Marketplace. Maybe it was added by eBay, as Marketplace suggests, or maybe Marketplace did it. Either way, it was only shown there, not in the eBay listing.
The seller did not use an AI description.
chevymontecarlo88
·1 year agoWow. I did not realize eBay was describing items without a way to edit or view. Thanks for the clarification @lacemaker3 !
valueaddedresource
OP1 year ago@chevymontecarlo88 the seller is not using AI in this instance, eBay is - without the seller's knowledge or explicit consent as far as I can tell.
Here's how the Facebook Marketplace partnership works:
eBay has auto-opted all listings in - unless you opt out, all of your active listings are eligible and may possibly be cross-posted by eBay to Facebook.
When eBay cross-posts a listing (again this is all done automatically by eBay, it is not something the seller is actively involved in), instead of showing the verbatim word for word description as entered by the seller on eBay, eBay is providing Facebook with a version of the description which has been summarized by eBay.AI (see my screenshots in the OP).
Sellers who haven't been paying attention to eBay announcements may not even be aware that their listings are being cross-posted to Facebook through this partnership.
https://community.ebay.com/t5/Announcements/Introducing-eBay-s-partnership-with-Facebook-Marketplace/ba-p/34868556
And even those who are aware of it are likely not aware that eBay has taken it upon themselves to provide AI summarized descriptions instead of what the seller actually entered on the listing.

·1 year agoThis is all good to know - thank you for posting a clear explanation of what eBay is doing.
In order for someone who first sees the eBay lising on FB, however, would they not be directed first to the actual listing on eBay, where the seller's original and correct description would be available for the buyer to read?
Of course in any case, fewer and fewer buyers bother to read the description at all. And I agree that eBay mucking with the description to cross post the lsting is just plain wrong.
valueaddedresource
OP1 year ago@knifeaholic that's a fair point. But as you say, fewer and fewer buyers even bother to read the description when they start on eBay - realistically how many are going to take the time to scroll down the page to look at that info if they believe they've already seen it on the Facebook listing?

valueaddedresource
OP1 year ago@bandrhome looking through this seller's store, they do have some other listings which are described as being a "grab bag" of stickers or decals.
While none of them contain the exact wording the AI added in, it's likely that it drew from some of those other listings when creating that part of the description - which is of course still hugely problematic, just explaining where things are likely going wrong.
bandrhome
·1 year agoOh I get that, I was picking on the AI. Haha
AI should 'read' the photos in the actual listings. I know its implemented in to Etsys search engine. They made a big photo change. No collages, etc so AI can tell what you sell.
