How do you think Google can motivate 3rd party advertisers?  I&#x27;m talking about the Rubicons, Pubmatics, etc.   Google doesn&#x27;t have any real leverage over them.  Other than the fact that as publishers do move to SSL (because of the SEO penalty that non SSL sites have) they won&#x27;t use the SSPs that don&#x27;t demand or can&#x27;t insure 100% SSL for their buyers.  So in effect Google is putting pressure on them to do it.<p>I don&#x27;t understand your next part at all.  Who would charge a premium to http only networks?  Those sites don&#x27;t actually rely on Google for delivery.
