But, ads directly correspond to revenue stream, and a loss of ad "impressions" would result in a reduced revenue stream, so a "protect the advertising" response is not at all unusual to consider as a portion of their (eBay's) reasoning for this ban.
Given how hard they push sellers to purchase their "extra cost listing enhancements" (i.e., purchase to have your listings show in the "advertisement" spots) it appears that they may make a decent revenue stream from these advertising angles. An AI-agent could find listings without going through the advertising displays and as such cut into this revenue stream.
An AI-Agent browsing eBay for a "widget" for a given individual will also likely not be browsing eBay's advertising listings (sponsored and promoted listings [1]) which would potentially equate to a loss in ad revenue for eBay. So there is likely a "protect the advertising moat" aspect to their "ban" as well.
[1] Given how hard eBay pushes sellers to purchase the sponsored and promoted listing tiers (at an additional fee of course) implies they make some nice revenue stream from these advertisements.
And, at least in the US, eBay charges their "final value fee" percentage on the order total (the sale price plus the shipping price paid by the buyer). So if the item has a 3% final value fee (the percentages differ across different categories of listings) then Ebay got $0.44 of additional fee from your $14.65 of shipping you paid to the shipping service. And there is no option to obtain a rebate on actual shipping paid, even if one purchases the shipping label from eBay themselves.
I suspect they (eBay) do this to avoid folks listing items for $1.00 with $194.00 shipping to avoid paying eBay any fees.
From what I've seen discussed, it seems some percentage of "sniping" is to attempt to obtain both "winning bid" and "lowest possible price" (note, not the same as "max willing to pay for the same item"). The sniper is trying to hide interest, so as not to attract other interested bidders, and therefore grab "a great deal" of a small increment above the starting bid price.
And this probably appears to work enough times in the snipers favor to trick them into thinking it is a winning strategy, whereas they likely would have won the same auctions in the end by just bidding that 'minimum' as their maximum bid. But as they can't easily (i.e., without expense) A/B test their strategy, they get no feedback that sniping isn't really helping them like they think it is helping them.
> But as they can't easily (i.e., without expense) A/B test their strategy
There also isn't really any detriment. At worst, the sniper is making the same bid they would have made otherwise. If the opposing bidders are not purely rational, and have not put in their actual maximum bid, then sniping can deprive them of that opportunity and thus lowers the hammer price.
And bidders are not purely rational, especially when the items are not purely utilitarian. Getting notifications that you have been outbid has an emotional effect, as does having time to think about raising the bid.
they notify the bidder when they're outbid, and the incremental price increases can make it tempting for someone to adjust their idea of their max price. sniping deprives them of that opportunity.
This is most likely the reason. I could see a lot of "buy for me bot" users deciding that they really did not mean that color shirt (or some other reason) when they asked it to buy a "brand X shirt in size Y" and forgot to tell the bot what colors they would accept as options and did not realize the bot might buy an "electric purple" (or some other color they dislike) shirt because it was not constrained in color choice.
Auto bid does not hide any information even with one bidder, as ebay indicates that "1 bid" has occurred.
The only way auto-bid could hide information is if eBay treated auto bid as "silent auction" style. Show "zero bids" all the way to the end, then once closed, see which 'auto-bid' came in highest and declare that bidder the winner.
Sniping is attempting to recreate 'silent auction' style bidding, with a bid system that is not 'silent'.
From what I understand, the reasoning behind the snipe method of bidding is to avoid showing to other bidders that there is interest, leading to the, supposed, outcome of more likely being the only bidder and thereby receiving the item at the sellers starting bid price (or slightly above) rather than at the "max one was willing to pay" price.
> You won't pay final value fees or regulatory operating fees
Of course, they will likely find some other way to extract their fees.
It would be nice, however, if the final value fee went away for US non-professional sellers.
There does seem to be no indication (at least on the page you linked) of how they define "private seller", which also opens up the possibility of them defining it so narrowly that, say, only five UK residents ever qualify.
Another eBay precursor auction side, onsale.com, had the same setup. The auction ended at X date/time or five or ten minutes (I forget which) after the last bid was made.
> Tariffs/subsidies should be weaned off over time.
The economic problem is that so long as the production cost imbalance exists, weaning off the tariffs just creates the same market forces that created the trade imbalance (and export of jobs) that created the situation in the first place.
I.e., if it inherently costs $5 to make a "widget" in Elbonia [1] and it inherently [2] costs $25 to make the identical (in every way) "widget" here [3] then while a tariff of $20/widget would make both equal in price, any reduction in the tariff will make the Elbonian made widget cheaper, and a purchaser will be incentivized to buy the Elbonian made one over the "made here" version because they, individually, save money by doing so.
So to maintain the widget making industry "here" the tariff has to be maintained. Any reduction and the cost incentives of "made in Elbonia" reappear, and the local manufacturer sees a corresponding drop in sales.
[1] Chosen only because it is not a real place.
[2] Meaning the local manufacturer cannot possibly produce one for less, due to higher costs "here" (e.g., energy costs, raw materials costs, labor costs, insurance costs, etc.)
Given how hard they push sellers to purchase their "extra cost listing enhancements" (i.e., purchase to have your listings show in the "advertisement" spots) it appears that they may make a decent revenue stream from these advertising angles. An AI-agent could find listings without going through the advertising displays and as such cut into this revenue stream.
