How might a search engine approve or reject ads automatically, without human review, on the basis that the ads are annoying or displeasing in some way?
Without considering the very large volume of ads that get presented to Google everyday, you might think that they would manually review every ad that advertisers present for publication, which would take a lot of people. While ads should attract some attention, they shouldn’t be annoying or offensive. There are a number of standards set from Google for image ads, video ads, and for text ads.
A patent application from Google goes into a good amount of depth on how it might take a programmatic approach to identifying ads, and Web pages that are “annoying.”
The patent filing describes some of the methods used when reviewing images and text and audio, with tools like Optical Character Recognition and pattern matching against large databases of images and sounds. It also details how Flash and animated images might be reviewed, but is silent on what it is looking at when it refers to things like a “Trust Score.”
