If an item is not made of silver, do not put the word "silver" in the title just because the item has a silvery finish. If the item contains "Faux Pearls" list it as a "Faux Pearl" Necklace or Bracelet, not a "Pearl" one. If the item is made of a simulated stone, do not list it with the name of the natural stone in the title. Being accurate in your listings and their titles is very important to the integrity of the site.
Frankly, if the title of a listing says "Silver Cross Necklace" and I discover upon reading the listing that it is actually made of a base metal with a silvertone finish, there is a good chance that I would not only not purchase the item, but would consider the seller as engaging in deceptive practices. Of course, if I were new to the site, I'd probably look at the other listings there with some skepticism. This I think would hurt all the sellers.
I urge all sellers of jewelry, and any other item for that matter, to be very careful in their descriptions and titles. If the item is "faux leather," a "faux pearl" or a "simulated stone" make sure it isn't titled to give the impression that it is the real thing. This goes for trying to fool the search engine into thinking it belongs in a search return for the real item as well as trying to deceive people.
I also urge everyone that finds this sort of thing being done to report the listing. Remember that such practices, if permitted to go on, reflect badly on the site and all sellers associated with it.
I also urge eBid to take these reports seriously and take appropriate action to curb the use of this deceptive practice.
