That second link will still help you because it will pass extra PR to that page. But in terms of anchor text, most of the experiments I’ve seen show that the second link’s anchor text probably doesn’t help. That being said, Google is more sophisticated than when a lot of these came out so they may count both anchors. But to stay on the safe side I recommend adding keywords to navigation links if possible.

As of 2009, there are only a few large markets where Google is not the leading search engine. In most cases, when Google is not leading in a given market, it is lagging behind a local player. The most notable example markets are China, Japan, South Korea, Russia and the Czech Republic where respectively Baidu, Yahoo! Japan, Naver, Yandex and Seznam are market leaders.
Thanks for bringing up this point - I agree Eric - competitive positioning can help you determine value that you bring to the table that your competitors dont.  I'm all for it.  Neilsen does some reports that provide awareness, likelihood to recommend, sentiment and other insightsfor your site/brand and your competitors. You can also pull some of that type of insight out of social listening platforms like NetBase, SM2, Radian6, Dow Jones, Nielsen, and so many others.  I've even done some hacked compeitove sentiment comprisons before using Search: searching for [brand or feature] + "like", "love", hate", "wish" etc. 
Brian, great post as always! Question: Do you consider authority sites (industry portals) a form of “influencer marketing?” e.g. guest blogging, etc? In some niches there are not so many individuals who are influencers (outside of journalists) but there are sites that those in the industry respect. I am in the digital video space and for me one site is actually a magazine that is building a very strong digital presence. Thanks, keep up the good work!

Thanks for the very, very in-depth article. I am a real estate agent in Miami, Florida and have been blogging all-original content for the past 21 months on my website and watched traffic increase over time. I have been trying to grow my readership/leads/clients exponentially and have always heard about standard SEO backlink techniques and writing for my reader, not influencers. Recently, I have had a few of my articles picked up and backlinked by 2 of the largest real estate blogs in the country, which skyrocketed visits to my site. Realizing what I wrote about, that appealed to them, and now reading your article, I am going to continue writing in a way that will leverage those influencers to help me with quality backlinks.

Although this is a step-by-step series, everyone's methods will (and should) vary, so it really depends on how much time you think it will take (if you're billing hourly).  What tools do you have at your disposal vs. how much researching for information will you have to do on your own? Will you have to pay for research reports or companies? Do you pay a monthly service for data or research?
We expect advertisements to be visible. However, you should not let the advertisements distract users or prevent them from consuming the site content. For example, advertisements, supplement contents, or interstitial pages (pages displayed before or after the content you are expecting) that make it difficult to use the website.

Meta tags. Meta tags still play a vital role in SEO. If you type any keyword into a search engine, you’ll see how that keyword is reflected in the title for that page. Google looks at your page title as a signal of relevance for that keyword. The same holds true for the description of that page. (Don't worry about the keyword title tag -- Google has publicly said that it doesn't pay attention to that tag, since it has been abused by webmasters and all those trying to rank for certain keywords.)

Think of it this way: The more specific your content, the more specific the needs of your audience are -- and the more likely you'll convert this traffic into leads. This is how Google finds value in the websites it crawls; the pages that dig into the interworkings of a general topic are seen as the best answer to a person's query, and will rank higher.

When Larry wrote about the kick in the proverbial teeth that eBay took from Google’s Panda update, we managed to secure a link from Ars Technica in the Editor’s Pick section alongside links to The New York Times and National Geographic. Not too shabby – and neither was the resulting spike in referral traffic. Learn what types of links send lots of referral traffic, and how to get them, in this post.
Search engines use complex mathematical algorithms to interpret which websites a user seeks. In this diagram, if each bubble represents a website, programs sometimes called spiders examine which sites link to which other sites, with arrows representing these links. Websites getting more inbound links, or stronger links, are presumed to be more important and what the user is searching for. In this example, since website B is the recipient of numerous inbound links, it ranks more highly in a web search. And the links "carry through", such that website C, even though it only has one inbound link, has an inbound link from a highly popular site (B) while site E does not. Note: Percentages are rounded.
