ad ranking on content n/w

[SEMblahblah]

how is an ad ranked on a content n/w page?is it solely depending upon the bid (since there is no quality score factor in case of a content campaign)?or does it depend on other factors like ad-landing page relevancy?
i mean..does the formula cpc bid*quality score still apply here?

Ads are positioned on search and content pages based on their Ad Rank. The ad with the highest Ad Rank appears in the first position, and so on down the page.

For a search campaign ad, the factors are known to you already.

A keyword-targeted ad's position on a content page is based on the ad group's content bid and Quality Score.
Ad Rank = content bid X Quality Score
The Quality Score related to Ad Rank on the content network is determined by:
* The ad's past performance on the site in question, as well as on similar sites
* Your landing page quality
* Other relevance factors

Google puts many other factors into lets say a "black box" and calls it "other relevance factors" I am positive that except for the guy who came up with the algo for the Q.S, and may be a few others in google, no one else knows all the "other relevance factors". Its mostly guess work and results from experimentation that we can know what they can be.
