Number of ads in the USA market?

[vrgoogler]

Hi,

How do I find out the number of ads in the USA for a particular
keyword?

If I am not from the USA, I would need a USA proxy server to view the
number of ads in Google.com by searching manually. Can the API give me
the information I want without a USA proxy and the need to visit
Google.com?

Hello,

You can retrieve an approximation of how much competition there is
for particular keywords by making a
KeywordToolService.getKeywordVariations() call and checking the
advertiserCompetitionScale in the resulting KeywordVariation objects.
You can specify the language and geo targeting options of your choice
when calling getKeywordVariations().

That's the only Google-sanctioned way of determining that information
that I know of.

When I use the adwords form above, I see the competition as some kind
of horizontal meter. I want to see the number of advertisers in
numbers and not some graphical representation.

Will KeywordToolService.getKeywordVariations() give me that?

[AdWords API Advisor]

getKeywordVariations() provides the same fundamental information as
the KeywordToolExternal web application, represented as a number on a
scale of -1 to 5 rather than a graph.

I don't know of any way to get the exact numbers you're looking for,
and it doesn't sound like information that would be made available
except as a rough estimate.
