Google recently announced Instant Search. Now how would ads be displayed on the search pages? And how would AdWord advertisers be charged?
Lets say someone were to type ‘flow’ with the intention of searching for flowcharts. But Googles predicative search algorithm would feel the search is for flowers and immediately display ads for flowers!
By the time the user were to completely type flowcharts, the flower ads would have displayed and gone and be replaced with flowchart ads.
Now would the flower advertiser be still charged for the impression which may have stayed just for a few seconds?
Google has clarified saying the following:
Google Instant changes the way we think about impressions. With Google Instant, an impression is counted if a user takes an action to choose a query (for example, presses the Enter key or clicks the Search button), clicks a link on the results page, or stops typing for three or more seconds.
It’s possible that this feature may increase or decrease your overall impression levels. However, Google Instant may ultimately improve the quality of your clicks since it helps users type queries that more directly connect them with the answers they need.
So in short, if the advertisement is displayed for 3 seconds or more, it will be counted as an impression!
So many ifs and buts! What if a use takes more than 3 seconds to remember the correct spelling? What if he back-tracks after typing in a different spelling? Well if the ad is displayed for 3 seconds or more, it will be charged as an impression!
