Click through rates: Searches using terms that denote high purchase intent such as product or brand-specific keywords will get more clicks than organic results. The advantage of paid search can clearly be seen in the Internet retailers MarketLive Performance Index data. For the year 2013 as a whole, PPC accounted for 36.5% of search traffic but an outsized 47.9% of revenue from search.
Content is one of the 3 main Google ranking factors. As a matter of fact, having a blog can help you get your content indexed faster. An active blog – relying on qualitative and insightful content, and backed by authoritative links – will help you improve your rankings and thus your organic traffic. Also, long-form copies (above 1200 words) tend to rank higher and be crawled more often.
Well as noted in the post it is not just above the links that was only one key part of a wider strategy. This website in question has deep levels of content. So it is not just about a blog section, they have numerous high quality content sections we have developed over time. It would not be advisable ever to attack competitors sites with low quality links.
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.
