When would this be useful? If your site has a blog with public commenting turned on, links within those comments could pass your reputation to pages that you may not be comfortable vouching for. Blog comment areas on pages are highly susceptible to comment spam. Nofollowing these user-added links ensures that you're not giving your page's hard-earned reputation to a spammy site.
Nice work Laura! This is going to be a great series. I'm working my way through SEOmoz's Advanced SEO Training Series (videos) Vol. 1 & 2 to build upon the advice and guidance that you and your team provided to me during my time at Yahoo!. Now many others will benefit from your knowledge, experience and passion for SEO strategy and tactics. Best wishes for great success in your new role.
We often see posts on how to get blog topic ideas or ideas on creating visuals but nobody ever talked about new link building ideas. The ways you showed here some are absolutely unheard to me. You know what I think you should write a post on how to get your own link building ideas…where to start…how to proceed…how do I know it’s full proof…it surely comes with lots of experiments…but the point is starting…….I know sounds weird but I know you will come up with something 🙂
Keep resources crawlable. Blocking page resources can give Google an incomplete picture of your website. This often happens when your robots.txt file is blocking access to some or all of your page resources. If Googlebot doesn't have access to a page's resources, such as CSS, JavaScript, or images, we may not detect that it's built to display and work well on a mobile browser. In other words, we may not detect that the page is "mobile-friendly," and therefore not properly serve it to mobile searchers.

Smartphone - In this document, "mobile" or “mobile devices" refers to smartphones, such as devices running Android, iPhone, or Windows Phone. Mobile browsers are similar to desktop browsers in that they can render a broad set of the HTML5 specification, although their screen size is smaller and in almost all cases their default orientation is vertical.

This toolbar is based on the LRT Power*Trust metric that we’ve been using to identify spammy and great links in LinkResearchTools and Link Detox since 2012 and the free browser was just recently launched. It helps you promptly evaluate the power and trustworthiness of a website or page during your web-browsing way exacter than Google PageRank ever did.
If you create content that people enjoy it can easily become popular or even go viral. The important thing is to put your website and content in front of people that are looking for it, right? Social bookmarking is a super easy way to do just that. Social bookmarking sites allow users to bookmark their favorite websites that other people can publicly view and vote up or down. If you bookmark useful content other people will find it, share it, and vote it up so others can enjoy it. Oh yeah, and it only takes about 30 seconds to bookmark your site. The 3 most popular social bookmarking sites are Digg, Reddit, and Delicious. These 3 sites get over 8 MILLION unique visitors a month – funneling off a chunk of that traffic to your website is very doable. (There’s plenty to go around ) Just remember to create content that people will enjoy and/or find useful. The most popular content on social bookmarking sites are usually check lists, “Top 10” lists, tools & resources, and breaking news – so keep that in mind!
“In conclusion, this research illuminates how content characteristics shape whether it becomes viral. When attempting to generate word of mouth, marketers often try targeting “influentials,” or opinion leaders (i.e., some small set of special people who, whether through having more social ties or being more persuasive, theoretically have more influence than others). Although this approach is pervasive,recent research has cast doubt on its value (Bakshy et al. 2011; Watts 2007) and suggests that it is far from cost effective. Rather than targeting “special” people, the current research suggests that it may be more beneficial to focus on crafting contagious content. By considering how psychological processes shape social transmission, it is possible to gain deeper insight into collective outcomes, such as what becomes viral.”
Website owners recognized the value of a high ranking and visibility in search engine results,[6] creating an opportunity for both white hat and black hat SEO practitioners. According to industry analyst Danny Sullivan, the phrase "search engine optimization" probably came into use in 1997. Sullivan credits Bruce Clay as one of the first people to popularize the term.[7] On May 2, 2007,[8] Jason Gambert attempted to trademark the term SEO by convincing the Trademark Office in Arizona[9] that SEO is a "process" involving manipulation of keywords and not a "marketing service."
This one is so obvious, we’re going to look at it first. Paid search, social media advertising and display advertising (try our Smart Ads Creator!) are all excellent ways of attracting visitors, building your brand and getting your site in front of people. Adjust your paid strategies to suit your goals – do you just want more traffic, or are you looking to increase conversions, too? Each paid channel has its pros and cons, so think carefully about your objectives before you reach for your credit card.
Page and Brin founded Google in 1998.[23] Google attracted a loyal following among the growing number of Internet users, who liked its simple design.[24] Off-page factors (such as PageRank and hyperlink analysis) were considered as well as on-page factors (such as keyword frequency, meta tags, headings, links and site structure) to enable Google to avoid the kind of manipulation seen in search engines that only considered on-page factors for their rankings. Although PageRank was more difficult to game, webmasters had already developed link building tools and schemes to influence the Inktomi search engine, and these methods proved similarly applicable to gaming PageRank. Many sites focused on exchanging, buying, and selling links, often on a massive scale. Some of these schemes, or link farms, involved the creation of thousands of sites for the sole purpose of link spamming.[25]
#16 is interesting because no one really knows about it. Myself and a former colleagu did a test on it about 4 years ago and published our results which conculded what you are saying. Since then I’ve been careful to follow this rule. The only issue is that often times using the exact kw does not “work” for navigation anchor texts. But with a little CSS trickery one can get the code for the nav bar to be lower in the code, prioritizing contextual links. I’ve also seen sites add links to 3-5 specific and important internal pages with keyword rich anchor texts, at the very top of the page in order to get those important internal links to be indexed first.

Think of this document as a living communication between you and your client or boss. It is a document you should refer to often. It keeps all parties on the same page and aligned. I recommend sharing it in a collaborative platform so updates are shared between all viewers without having to constantly send out new copies (nothing sucks the life out of efficiency faster than "versioning" issues).
Regarding internal linking, i believe that in the case of two links pointing to an internal page, being one of those links in the group i mentioned above, they will considered only the one witch feed the algorithm with more information. In sites that have the menu before the content, it will be the second link. I think that’s the smart way for them to analyse all the links to better understand the destination page content. And they are smart 😉 .

This was all free information I found online in less than an hour, that gives me some great ideas for content, partnerships and potential tools to build into my site to be relevant and useful to my target audience. Of course this is just some quick loose data, so I'll emphasize again: be careful where your data comes from (try to validate when possible), and think about how to use your data wisely.


Practicing SEO now for over a decade, I don’t often come across many blog posts on the subject that introduce me to anything new — especially when it comes to link building. However, I must admit, after reading your article here I had to bookmark it to refer back to it in the future, as I’m sure it will come in handy when doing SEO for my websites later on down the road.
This truly amazing and I’m gonna share this with like minded people. I loved the part about flippa. What a great source to get ideas. Building links tends to be the hardest to do, but a few good quality links is all you need now a days to get ranked. I currently rank for a very high volume keyword with only 5 links all with pr 3,4 and good DA and PA. Good links are hard to get but you only need a few which is encouraging! Props for this post!
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. 
When Googlebot crawls a page, it should see the page the same way an average user does15. For optimal rendering and indexing, always allow Googlebot access to the JavaScript, CSS, and image files used by your website. If your site's robots.txt file disallows crawling of these assets, it directly harms how well our algorithms render and index your content. This can result in suboptimal rankings.
This philosophy is beautiful in its simplicity, and it serves to correct the “more, more, more” mentality of link building. We only want links from relevant sources. Often, this means that in order to scale our link-building efforts beyond the obvious tactics, we need to create something that deserves links. You have links where it makes sense for you to have links. Simple.
For some reason I had to delete some pages, these pages are using the HTML suffix, so I blocked them in robots.txt use Disallow: /*.html, but it’s been almost a year, I found that google robot often capture these pages, How can I quickly let Google completely remove these pages? And I have removed these URL from google webmaster tool by google index-> remove URLs, but Google still capture these pages.
