It's important that all sellers know how important keywords are in every listing on eBay and it has been proven to increase sales. A keyword is simply a normal word however it is used to help optimise the listing (sort of the same thing you would do for a web site).
In this guide I will use the following example listing title:
"SD Memory Card for PSP Console ***** NEW - NO RS *****"
So at the moment with this title the listing will be found if the user searches "PSP SD Memory Card" (not considering the category of the listing), The ebayer selling this item is missing out on 100's of views because of the few keywords he/she has used, at the moment we have the following main keywords:
-SD Memory Card
However SD Memory cards are also used in:
So, we're are missing out on a lot of traffic, to take advantage of this traffic you could change your listing title to include more keywords, here's our new title:
"SD Memory Card for PSP Console PDA PC Camera Wii Mobile"
Try it! you will be amazed by the results, however remember that it's against eBay's policy to make the listing seem something that's its not, so putting a title like "New Boys Shirt not for Girls" would not be allowed.
Enjoy and good luck!
