In the zero-results sets, Google was still willing to show AdWords, which means if we have customer targets, we can use remarketed lists for search advertising (RLSA), or we can run paid ads and still optimize for those. We could also try and claim some of the data that might show up in zero-result SERPs. We don't yet know what that will be after Google rolls it back out, but we'll find out in the future.
At our agency, we work with sites of varying sizes, from very large to quite small, and recently, we have noticed a trend at the enterprise level. These sites aren’t relying as much on Google for traffic any more. Not only are they not relying on Google traffic, but also, the sites are getting less than 10 percent (or slightly more) of their organic traffic from the search giant.
