Network marketing: Network marketing companies have a great business model (for those who own the company), because they only pay their sales people (a.k.a. “independent business owners”) when they make a sale or recruit another person. They only pay on performance. So to sell a bunch of product, the direct sales company really doesn’t go directly to the consumer through TV or magazine ads or similar methods that could easily cost millions; instead they go indirectly through their sales people and only pay for the word of mouth advertising as a commission on a product sale. It’s really savvy business strategy that’s low-risk and high-reward, if it spreads far and fast enough by emotionally exciting the distributors. Distributors are heavily using social media like Facebook, YouTube, blogging and the like to generate sales and grow their network online.
These types of keywords each tell you something different about the user. For example, someone using an informational keyword is not in the same stage of awareness as someone employing a navigational keyword. Here’s the thing about awareness. Informational needs change as awareness progresses. You want your prospects to be highly aware. If you’re on a bare-bones budget, you can be resourceful and achieve that with one piece of content.
It increases relevancy: Siloing ensures all topically related content is connected, and this in turn drives up relevancy. For example, linking to each of the individual yoga class pages (e.g. Pilates, Yoga RX, etc) from the “Yoga classes” page helps confirm—to both visitors and Google—these pages are in fact different types of yoga classes. Google can then feel more confident ranking these pages for related terms, as it is clearer the pages are relevant to the search query.
Good question, for most directories I use they ask for mobile number to send a message of verification, for the ones which phone you for verification inform the company before hand to tell their customer service people to be ready. I know the bigger the company the more tricky these things get you just have to find out what works best to answer the calls even if they give you a direct number to use. 
Solid analysis on this tough topic Rand. It will definitely be interested to see what in-serp features Google continues to add to keep you on their site as opposed to clicking through to a website. I think SEOs need to take more consideration into branding and content marketing tactics in order to supplement potential lost organic traffic as time goes on.
Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
