Please, let me know what is wrong with my items/tags/product names.
The thing is, when the default search by relevancy was set some time ago, my items were among those on the first pages of search under the tag "shawl pin", now (or rather, a year ago) they have disappeared from the first 20 pages or so. I studied carefully the tags used by the sellers whose items do appear at that search, they are quite similar with mine.
As I tried to apply the most used tags to my new listings, I can see the result - my NEWLY LISTED items stay among the top items (like 1-10th pages), then they totally disappear, found only on pages after 20th. Other sellers' items stay as they were! Plus thers appear like on every or every other page among the first pages. I thoroughly doubt they renew their items in that amount so often!
That's totally frustrating, for me that tag 'shawl pin' was very important, it brought me most sales. Plus I have quite a number of such items, so what is wrong?
P.S. other related searches, such as fibula, copper shawl pin or copper brooch show my items in the first pages of search.
