Remember those Gulf Hurricane Relief ads upon a Google network? They were PSAs
When Google is not able to offer applicable AdSense ads upon a web page, a complement will arrangement Public Service Ads instead of a unchanging ads to foster organizations similar to Red Cross, Direct Relief, etc.
Unlike a unchanging AdSense ads, web publishers do not get paid for clicks done upon Public Service Ads as well as even Google doesn't have any distinction by using such ads.
In their own words - “PSAs have been non-profit classification ads which have been served to pages when targeted ads have been unavailable, or when Google is incompetent to accumulate calm from a page.”
Wikipedia as well defines a open use proclamation as “a non-commercial announcement broadcast for a open good.”
Google launched their own 2008 U.S. Election site in Aug that, similar to a portal, links to report about US elections accessible upon alternative Google Sites similar to YouTube, Knol, Google Maps, etc.
Now if we occur to mark an AdSense PSA upon a little site (like here), chances have been which it will be about Google's own Elections website as in a screenshot above.
This is startling since this “ad”, yet a PSA, doesn't fit in Google's own clarification of PSA (non-profit classification ads) nor which of Wikipedia (non-commercial advertisement).
Here's what ABC News has to contend about Google's elections page - “the brand new applications have been partial of their bid to raise a poke giant's impasse in U.S. governing body and, ultimately, to turn as executive to a electoral process as Google as well as YouTube have been to media usage.”
All a unoccupied AdSense register is assisting Google foster their elections page though am not certain if these ads systematise underneath PSAs or “free advertising” since Google does have “commercial” seductiveness here.
