AdWords Complains

[swain]

Hi,

I have used Google Adwords for long time, and I am experiencing a
problem with the logic of the system, making Google AND me both loosing
money.

This is the example: I have keywords A, B, C & D
Searching: A B C my ad appear
Searching: A B D my ad appear
Searching: A B C D my ad doesn't appear

Since A B C and A B D are very focused keywords sets my complain is
about why my ad doesn't appear on A B C D (seeing it as a very very
focused keyword set).

Obviously I contacted the Google Support for customers but they told me
to add: A B C D as a keyword... but doing simple math if I want to put
all cases this is a factorial problem...

Any ideas? have you tried it with your own ads?

Thanks,
Sebastian

I agree, if you are using A B and C as a phrase or broad match your ad should also be displayed for A B C D searches.

To make sure this is definately not being displayed I would follow Google's suggestion to create the exact match option for [A B C D], in addition to your current keywords. Google intermittently displays it's ad's so it may be a case of you missing them while searching but at least this way you can see if any impressions are being made, it may also highlight the keyword as being inactive for search meaning that your bid or quality score will need to be increased.
