I have seen a trend lately, specifically in the sports card categories, of auctions not only getting much lower than bids than normal or fixed priced items (examples include cards or sets that are in a $30-$50 range on a daily basis with multiple sales at fixed or even some auctions, to other auctions going under $10 or even getting 1 bid at 99 cents while some fixed priced just sit, the same days).
The sports card category receives heavy action in terms of volume being listed and selling, especially on new product.
I have been running searches for items, and often eBay will show 0 for sale, yet 5 minutes later it shows 4-5 for sale. This is happening with my own items that have been listed a day or two.
Sometimes I can't find them, or other times, my item will show up below the blue line that sometimes reads "Results matching fewer words" or "Similar items" or even "Items from International sellers" which I am not.
Anyhow I attached a screen shot from 7:40am eastern 11/5/2018 of just some of what I am seeing.
This screenshot is of completed items, and as you can see, it shows 0 results, yet shows the exact item I am searching twice under "Results matching fewer words". Yet if I change the search from "2018 topps update 150 miles" to "2018 topps update miles 150", they show up correctly.
However when I run the search for current items, eBay says ZERO results found. Yet, there are currently THREE listings on eBay for this item, and all 3 listing titles use the exact five words in my search.
Sure, there are various ways to find the items I am looking for, but my point is that eBay users don't always type words in a certain order, nor have they been trained by eBay on how to run various searches. It should not be this way; it certainly didn't use to.
If I search keywords, the items should populate...all of them!
The app is also a big mess when it comes to search, but that's another issue.
