Whilst working on a new SEO tool which will use the Bing API, I found an interesting statement in the Terms Of Use:


You will not, and will not permit your users or other third parties to:

directly or indirectly generate impressions or clicks on Bing results, or authorize or encourage others to do so, though any automated, deceptive, fraudulent, or other invalid means.


Does this mean that Bing use CTR and Impressions as a ranking factor? 

This has been dismissed before as a ranking factor for Google before due to the possibility of falsifying results by paying for clicks.   Has Bing found a way around this – or are they hoping that this ranking factor won’t be abused?
