Adwords Keywords

[Codythebest]

I just tried Adwords for the first time.
I did choose keywords. I have like 10-12 of them. However, on 1440 impressions for the first day, I got only 1 impression for one of my keywords.
So I assume my keywords are just not used for searching. Bad selection.
How can I check the keywords used by searchers impressing my ad?

Google does provide tools for that, before you select a keyword. It shows both search volumes and average price for the bid.

This tool actually choose keywords from the website.
But how can I know the keywords used by the searchers so far, which are not what the tool gave me?

There are many tools which do that Like Adwords Analyzer, Keyword Elite etc. Check them out.

I use Google analyzer but I can't see the keywords searchers are using to get to my site :(
