When I was an Ecommerce Director we captured 14,000 unique visitors a day to sell stuff to 500. Google has made that kind of waterfall marketing dangerous.
The new Google wants engagement, time on site, pages viewed and other site heuristic measures to improve. Credit Card based loyalty programs are already common. We expect 2015 will bring more inclusive loyalty programs that also value social support such as:
* Links & Likes.
* Creation of profiles.
* Brand Ambassadors.
