The iab has a CMP proposal to create consent dialogs on page load. See eg http://advertisingconsent.eu/ http://advertisingconsent.eu/ and an implementation by Quantcast https://www.quantcast.com/gdpr/quantcast-choice-self-serve/ https://www.quantcast.com/gdpr/quantcast-choice-self-serve/ .

I also think you will see some acquisitions of crappy publishers with lots of pageviews so that advertisers can get an end-user touch point.
