I have had my account active for over a week now, I have readjusted my daily budget / max CPC to $200/day / $1/click , and i still have not had even 1 impression. I was online with google chat, my campaign says it is active and a rep would get back to me with the details - still waiting over 3 days now. Anyone with ideas/ can relate to this let me know.
In the keyword view, put your mouse over the magnifying glass icon & use the diagnostic tool. More info at http://adwords.google.com/support/bin/answer.py?hl=en&answer=27342 . It'll tell you why your ad isn't running & possible remedies to the problem. Hope this helps!
Also, try searching for one of your keywords, and see if your advert appears (I assume that it won't, but it's possible that it's just appearing on page 15, and nobody's gone that far through the results).
First of all please check in which all countries your ads are running and where are you searching, after opening google search engine (default search is pointed to the country where you are located), for example, if you are located in US and your ads run in UK, you will not find your ads in Google search engine, here you will have to browse in google.co.uk or in the url bar you have to type &gl=uk at the end to enable search in UK. Second most important is the relevance of the ads to the keyword list selected. Not sure if it has been done correctly. One other important thing to watch is the quality score of the landing page. Increasing daily budget and CPC may not help you much unless you have other things right. Best of Luck!!
