Here is a little tip that certainly worked well for me in the past and which I will be re-applying to all my new eBid listings from now on.....
Haul in those overseas buyers by finding out whatever you are selling means in other languages and include them as effective comma-seperated tags at the foot of all your item descriptions. You can easily do this by using one of those freebie internet translators.
In my case for instance its: Unterkleid. Combinasion. Combinación. Onderkleed. Underplagg. 下着. Indumento intimo. Enagua, etc etc
My blog's stats show that a good number of visitors each day use search engine terms in their own language and those same stats show that they refer directly to my various auction stores.
Go on - it only takes a few minutes and could make extra sales......
