Hi Chris, "Good content" means a couple of things - good for readers and good for Google. Good content for readers means that the content answers questions, provides value, offers solutions, and is engaging. You want to keep the reader on the page and on your website for as long as possible. To make good content for Google, you have to provide the search engine with a set of signals - e.g., keywords, backlinks, low bounce rates, etc... The idea is that if you make good content for readers (engaging, valuable, actionable, and informative), your content will get more engagement. When your content gets more engagement Google will see it as good content too and put it higher in the SERPs. Making "good content" is about striking that balance. Let us know if that answered your question!

Retailers are increasingly focusing on their online presence, including online shops that operate alongside existing store-based outlets. The "endless aisle" within the retail space can lead consumers to purchase products online that fit their needs while retailers do not have to carry the inventory within the physical location of the store. Solely Internet-based retailers are also entering the market; some are establishing corresponding store-based outlets to provide personal services, professional help, and tangible experiences with their products.
Mobile traffic: In the Groupon experiment mentioned above, Groupon found that both the browser and the device matter for the ability of web analytics to track organic traffic. Although desktops using common browsers saw a smaller impact from the test (10-20 percent), mobile devices saw a 50 percent drop in direct traffic when the site was de-indexed. In short, as mobile users grow, we are likely to see direct traffic rise even more from organic search traffic.
