If my website showed up at #20 but the user just clicked on #1 and never saw my website because it was on the second page, does that count as an impression?That impression means - your listing appeared for a given query but that has got nothing to do whether the user saw it or not..

impressions mean that someone actually saw (search for any keywords) your link (appears) in the search engine (google)
