Simple question – Lets say I have a blog/site with lot of outgoing links (avg 10 links per page). All the outgoing links (in the editorial content and user generated ones) are nofollowed, while all the internal links are “open”. I might have manually “opened up” some links in the editorial content because I’m so sure of their authority (ex:-google faq pages).
A great number of people who deal with SEO confuse backlink building and backlink earning. These notions are different. What is backlink building? It means to create conditions for SEO backlink referring to your site. To earn a backlink means to deserve it. Is that really possible? Yes! If you want your site to be worth earning backlinks, you must do everything possible and impossible to please your guests and users.

Mani, could not agree more your statements. It’s no wonder the SEO industry has such a bad name and it’s 99.9% Snake Oil. Still, Google, this Blog and other “SEO” sites are partly responsible for the PR hysteria, link spam and email spam for PR. Google should also put an end to Webmasters being screwed by SEO, but placing a BIG prominet statements on their Webmaster pages along the lines of;

So, as you build a link, ask yourself, "am I doing this for the sake of my customer or as a normal marketing function?" If not, and you're buying a link, spamming blog comments, posting low-quality articles and whatnot, you risk Google penalizing you for your behavior. This could be as subtle as a drop in search ranking, or as harsh as a manual action, getting you removed from the search results altogether!
The internet was the little guy savior, simple sites could rank well locally. Sadly your company is in the process of destroying that. In this economy small business with zero page rank that are listed on page 22 of results, need to be found in order to survive. My customers are really suffering because of the work that is coming out of Google, it keeps getting worse. Their conversions are still good coming out of Yahoo and MSN and now Bing. They do not have the resources to produce blogs, forums, or $5,000 websites let alone pay for Adwords when they are just trying to pay rent and not a lot of people can do their own web production.
Black hat SEO is to be avoided. This is basically link spamming. You can pay somebody peanuts to do this on your behalf and, for a very short period, it brings results. Then Google sees what’s happened, and they delist your site permanently from search engine rankings. Now, you need a new website and new content, etc.—so, black hat SEO is a terrible idea.
The paper’s authors noted that AltaVista (on the right) returned a rather random assortment of search results–rather obscure optical physics department of the University of Oregon, the campus networking group at Carnegie Mellon, Wesleyan’s computer science group, and then a page for one of the campuses of a Japanese university. Interestingly, none of the first six results return the homepage of a website

Black hat SEO attempts to improve rankings in ways that are disapproved of by the search engines, or involve deception. One black hat technique uses text that is hidden, either as text colored similar to the background, in an invisible div, or positioned off screen. Another method gives a different page depending on whether the page is being requested by a human visitor or a search engine, a technique known as cloaking. Another category sometimes used is grey hat SEO. This is in between black hat and white hat approaches, where the methods employed avoid the site being penalized, but do not act in producing the best content for users. Grey hat SEO is entirely focused on improving search engine rankings.

Finally, start building links in relevant sites like business directories (especially local directories) relevant niche blogs and forums, and industry publications. Success at link building will result from a combination of good PR, smart marketing strategy, and of course, great content. Google has said that social media doesn’t impact rankings, but reaching out to social influencers can give your content traction on other channels that can be useful.

I think that removing the link to the sitemap shouldn’t be a big problem for the navigation, but I wonder what happens with the disclaimer and the contact page? If nofollow doesn’t sink the linked page, how can we tell the search engine that these are not content pages. For some websites these are some of the most linked pages. And yes for some the contact page is worth gaining rank, but for my website is not.

As you might know, backlinks and all marketing strategies are dependent on the competition and existing trends in your niche. So if the blogs and marketers in your country are still using older tactics like web 2.0 backlinks and blog comments, then does it even make sense to go for tedious strategies like outreach? Does it even warrant a good business ROI?

An omni-channel approach not only benefits consumers but also benefits business bottom line: Research suggests that customers spend more than double when purchasing through an omni-channel retailer as opposed to a single-channel retailer, and are often more loyal. This could be due to the ease of purchase and the wider availability of products.[24]
And looking at say references would it be a problem to link both the actual adress of a study and the DOI (read DOI as anything similar)? Even if they terminate at the same location or contain the same information? The is that it feels better to have the actual adress since the reader should be able to tell which site they reach. But also the DOI have a function.
Make it as easy as possible for users to go from general content to the more specific content they want on your site. Add navigation pages when it makes sense and effectively work these into your internal link structure. Make sure all of the pages on your site are reachable through links, and that they don't require an internal "search" functionality to be found. Link to related pages, where appropriate, to allow users to discover similar content. Denver Page Rank Click Here
