See an example of Googles AdSense contextual ads at the bottom
of this page.
As an advertisor within Adwords these are called - Content-Targeted
Advertising (Content-Targeted AdWords; Content AdWords).
Google detects and assigns a keyword/keywords to a page and then
these are matched with ads from their Adwords pay per click system.
An image is generated on the fly which is what you see below. I
know they look like text links, but it's actually one big banner
ad that uses image maps, this means Google can have some control
over the presentation of the links although publishers can customise
them within Google.
The main gripe advertisors have, and I raised this personally at
Search Engine Strategies is that you cannot seperate your Adwords
from your Adsense adverts. Becuase the nature of the ad delivery
is fundamentally different (searching = active , browsing = passive)
you get completely different response rates for different types
of ads, and therefore proffesional keyword advertisors want to seperate
them in order to have different copy in each. It is also said that
the ROI from AdSense is much lower that of Adwords. As a partial
solution you can choose to opt out your entire campaign within Google
from Content-Targeted Advertising if you want..
