A couple of #SEO
notes from this would-be non-SEO post:
1. Per comScore last August, Google accounted for nearly 69% of organic searches (http://searchenginewatch.com/article/2289560/Googles-Search-Market-Share-Shoots-Back-to-67
2. Starting in October 2011, Google began withholding organic keyword data from site owners (http://marketingland.com/dark-google-search-terms-not-provided-one-year-later-24341
), and the percent increased late last year (http://searchengineland.com/googles-not-provided-at-87-of-google-search-traffic-to-major-news-sites-report-174375
3. Per the Custora "ecommerce acquisition snapshot" provided by +Avinash Kaushik
, organic search crested at just over 16% in 2012, then fell slightly in 2013. In contrast, email showed a healthy increase, from just over 5% in 2012 to around 7% in 2013.
I know, there are too many factors at play to make a cause-and-effect, but I can't help but notice the coincidences. What I'd like to say, but can't prove, is that Google's keeping organic search keywords from publishers is having a deleterious effect on their organic search marketing, and we're seeing it reflected in the halted growth of organic search as a customer acquisition medium. As with everything in life, time will tell.
