Ebay Hidden Keywords

Does anyone know how to insert hidden keywords which ebay have banned in the listings but allow it to be linked in their search. For instance the word Viagra is not allowed on the title or description but certain sellers have managed to be listed when you search with the word Viagra.

View listing's page source code > search for your term, 'viagra' etc. , all the rest you will figure out by yourself.

e.g. here

http://www.ebay.com/itm/Olimp-Erekt...upplements_Nutrition&var=&hash=item1e873641fc

he just put it in MPN

item location works like a charm

MPN is a good idea ...
for example here : ebay itm/Triple-Strong-850mg-Performance-Enhancer-Sex-Aid-Libido-Lasting-Hard-ErectionXXX-/141566411726?pt=LH_DefaultDomain_3&hash=item20f60403ce
