A metric in Google Adwords that helps advertisers understand where, on average, their ads are showing in Google search results pages. There are usually 4 available ad slots at the top of a search result page (where 1 is the first ad, 2 is the second ad, etc), so for the best results advertisers typically want an average position between 1-4. Average position 5+ indicates that your ads are showing at the bottom of the search results page.
