shopping-ads are based on a highly competitive, dynamic, auction.
shopping-ads show based on the bid and quality.
a shopping-ad will only show if an item has
a high enough bid and high enough quality
to win a slot in the auctions.
impression statistics indicate if a shopping-ads is being shown --
searching for items cannot be used to determine if ads are showing.
if shopping-ads are not showing any impressions,
then the best likely course is unusually to either
increase the bid or improve the quality of both
the website and the data being submitted.
click statistics indicate if someone saw an ad and clicked on the ad;
the cost for advertising with google is per click -- cost-per-click.
this is mainly a peer-to-peer forum --
forum-members cannot settle or explain
any payment or invoice issues.
for payment and invoice related issues, google may be contacted directly:
