One thing is certain: interlinking sites doesn't help you from a search engine standpoint. The only reason you may want to interlink your sites in the first place might be to provide your visitors with extra resources to visit. In this case, it would probably be okay to provide visitors with a link to another of your websites, but try to keep many instances of linking to the same IP address to a bare minimum. One or two links on a page here and there probably won't hurt you.

1. Now that we know that weight/PageRank/whatever will disappear (outside of the intrinsic wastage method that Google applies) when we use a ‘nofollow’ link, what do you think this will do to linking patterns? This is really a can of worms from an outbound linking and internal linking perspective. Will people still link to their ‘legals’ page from every page on their site? Turning comments ‘off’ will also be pretty tempting. I know this will devalue the sites in general, but we are not always dealing with logic here are we? (if we were you (as head of the web spam team) wouldn’t of had to change many things in the past. Changing the PageRank sculpting thing just being one of them).
Google's founders, in their original paper,[18] reported that the PageRank algorithm for a network consisting of 322 million links (in-edges and out-edges) converges to within a tolerable limit in 52 iterations. The convergence in a network of half the above size took approximately 45 iterations. Through this data, they concluded the algorithm can be scaled very well and that the scaling factor for extremely large networks would be roughly linear in {\displaystyle \log n} , where n is the size of the network.

i.e. the PageRank value for a page u is dependent on the PageRank values for each page v contained in the set Bu (the set containing all pages linking to page u), divided by the number L(v) of links from page v. The algorithm involves a damping factor for the calculation of the pagerank. It is like the income tax which the govt extracts from one despite paying him itself.
Less than 2 years ago one could promote a website within a month with the help of PBN (Private Blog Network). Then Google created “a sandbox” which made a site owner wait no less than 3 months before the effect of PBN backlinks turned to be visible. There are two more negative factors: risk and financial investment. You will realize that neither your wasted time nor money were worth it. That’s why it’s better to rely on proper backlinks from real sites.

Meanwhile, the link spam began. People chasing higher PageRank scores began dropping links wherever they could, including into blog posts and forums. Eventually, it became such an issue that demands were raised that Google itself should do something about it. Google did in 2005, getting behind the nofollow tag, a way to prevent links from passing along PageRank credit.
A generalization of PageRank for the case of ranking two interacting groups of objects was described in [32] In applications it may be necessary to model systems having objects of two kinds where a weighted relation is defined on object pairs. This leads to considering bipartite graphs. For such graphs two related positive or nonnegative irreducible matrices corresponding to vertex partition sets can be defined. One can compute rankings of objects in both groups as eigenvectors corresponding to the maximal positive eigenvalues of these matrices. Normed eigenvectors exist and are unique by the Perron or Perron-Frobenius theorem. Example: consumers and products. The relation weight is the product consumption rate.
Game advertising - In-Game advertising is defined as "inclusion of products or brands within a digital game."[49] The game allows brands or products to place ads within their game, either in a subtle manner or in the form of an advertisement banner. There are many factors that exist in whether brands are successful in their advertising of their brand/product, these being: Type of game, technical platform, 3-D and 4-D technology, game genre, congruity of brand and game, prominence of advertising within the game. Individual factors consist of attitudes towards placement advertisements, game involvement, product involvement, flow or entertainment. The attitude towards the advertising also takes into account not only the message shown but also the attitude towards the game. Dependent of how enjoyable the game is will determine how the brand is perceived, meaning if the game isn't very enjoyable the consumer may subconsciously have a negative attitude towards the brand/product being advertised. In terms of Integrated Marketing Communication "integration of advertising in digital games into the general advertising, communication, and marketing strategy of the firm"[49] is an important as it results in a more clarity about the brand/product and creates a larger overall effect.
Collaborative Environment: A collaborative environment can be set up between the organization, the technology service provider, and the digital agencies to optimize effort, resource sharing, reusability and communications.[36] Additionally, organizations are inviting their customers to help them better understand how to service them. This source of data is called User Generated Content. Much of this is acquired via company websites where the organization invites people to share ideas that are then evaluated by other users of the site. The most popular ideas are evaluated and implemented in some form. Using this method of acquiring data and developing new products can foster the organizations relationship with their customer as well as spawn ideas that would otherwise be overlooked. UGC is low-cost advertising as it is directly from the consumers and can save advertising costs for the organisation.
Some backlinks are inherently more valuable than others. Followed backlinks from trustworthy, popular, high-authority sites are considered the most desirable backlinks to earn, while backlinks from low-authority, potentially spammy sites are typically at the other end of the spectrum. Whether or not a link is followed (i.e. whether a site owner specifically instructs search engines to pass, or not pass, link equity) is certainly relevant, but don't entirely discount the value of nofollow links. Even just being mentioned on high-quality websites can give your brand a boost.
I’ve never been particularly enamoured with nofollow, mainly because it breaks the “do it for humans” rule in a way that other robots standards do not. With other standards (e.g. robots.txt, robots meta tag), the emphasis has been on crawling and indexing; not ranking. And those other standards also strike a balance between what’s good for the publisher and what’s good for the search engine; whereas with nofollow, the effort has been placed on the publisher with most of the benefit enjoyed by the search engine.
The first component of Google's trust has to do with age. Age is more than a number. But it's not just the age when you first registered your website. The indexed age has to do with two factors: i) the date that Google originally found your website, and; ii) what happened between the time that Google found your website and the present moment in time.
Do you regularly publish helpful, useful articles, videos or other types of media that are popular and well produced? Do you write for actual human beings rather than the search engine itself? Well, you should. Latest research from Searchmetrics on ranking factors indicates that Google is moving further towards longer-form content that understands a visitor’s intention as a whole, instead of using keywords based on popular search queries to create content.
Online interviews are hot right now, and a great and easy way to earn backlinks to your website. Once you become the authority in your niche, you'll get lots of interview invitations, but until then, to get started, you have to make the first step. Look for websites that are running interviews and tell them you would like to participate and what knowledge you can contribute.
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;
Description meta tags are important because Google might use them as snippets for your pages. Note that we say "might" because Google may choose to use a relevant section of your page's visible text if it does a good job of matching up with a user's query. Adding description meta tags to each of your pages is always a good practice in case Google cannot find a good selection of text to use in the snippet. The Webmaster Central Blog has informative posts on improving snippets with better description meta tags18 and better snippets for your users19. We also have a handy Help Center article on how to create good titles and snippets20.
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.
On a blog the page rank should go to the main article pages. Now it just gets “evaporated” if you use “nofollow” or scattered to all the far flung nooks and crannys which means google will not be able to see the wood for the trees. The vast majority of a site’s overall page rank will now reside in the long tail of useless pages such as commentors profile pages. This can only make it harder for google to serve up the most relevant pages.
In my experience this means (the key words are “not the most effective way”) a page not scored by Google (“e.g. my private link” – password protected, disallowed via robots.txt and/or noindex meta robots) whether using or not using rel=”nofollow” attribute in ‘links to’ is not factored into anything… because it can’t factor in something it isn’t allowed.

Say I have an article on a blog with 5 links in the editorial copy — some of those links leading back to other content within the blog that I hope to do well. Then I get 35 comments on the article, with each comment having a link back to the commenters’ sites. That’s 40 links in all. Let’s say this particular page has $20 in PageRank to spend. Each link gets 50 cents.


If the assumption here is that webmasters will remove the nofollow attributes in response to this change, then why did take “more than a year” for someone from Google to present this information to the public? It seems that if this logic had anything at all to do with the decision to change the nofollow policy, Google would have announced it immediately in order to “encourage” webmasters to change their linking policies and allow access to their pages with “high-quality information.”
This isn't about off-the-shelf solutions. You need to really convey something illustrious and beautiful, then fill it with incredible MVP content. Over time, this will become a thriving hotbed of activity for you, where people will come by and check-in repeatedly to see what you're talking about and what value you're delivering. Keep in mind that this won't happen quickly. It will take years. Yes, I said years.

SEO is an effective tool for improving the volume and quality of traffic to your website. Visitors are more likely to click on free organic listings than on paid listings. Our SEO strategies apply only the best and most current practices that focus on the use of great content development, content marketing, social media. All of these strategies combined result in the most effective use of best practices that drive long term ROI.
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!
