Back a few months ago when Google was putting the push on websites switching to the use of HTTPS it was pointed out that for Adsense publishers that doing so would reduce the pool of available ads because only HTTPS landing pages can be linked to from Adsense ads on HTTPS sites.
Has anything changed or advanced here? Is there any movement on the Adwords side of things where Google is pushing advertisers to use HTTPS so to increase the available ad pool?
I would consider changing over (only because that seems to be what Google wants and one day that might be more of a factor in the algorithm) but not if it's going to cost me a high percentage of income.
