The Evolution of Search

Google has further enhanced the visibility and impact of PLAs greatly — and hastened the demise of traditional free product search listings — by implementing a design that works across devices. PLAs are now available to you on your laptop or iPhone, and virtually any device in between.

The evidence couldn't be clearer that organic traffic is falling prey to PLAs, Google Maps and the Knowledge Graph. It's no longer a question of if, but to what degree. The results will be different on every site.
