I'm having a heck of a time justifying adcenter on a day by day basis.
This morning i received a bunch of editorial declines because product numbers were being denied for being a phone number. Sorry, but thats just "cheasy" if you ask me.
For example i use the KeyWord text in my ads akin to:
{KeyWord:Huge Inventory} in Stock
Huge Selection of products in Stock. Fast blah blah
http://www.widgetssss.com/?search.asp&keyword={KeyWord}
In this case the keyword is "970264-0403" which is a logitech speaker set but all of my logitech product numbers - which people search for have been denied for being a telephone number. Sort of dissapointing since bidding on "desktop speakers" is worthless on adcenter as well.
