I’m a bit confused now. If it is better not do place a nofollow, so why does it happen on this site? On the other hand, many sites have a place, where visitors can place links (like this one right here). And so the owner of the page does not guarantee for the links placed (makes sense, since they are not reauthored). So I don’t want do be associated with bad sites and do a no follow. Seems like a workaround, lets see whats going to happen in future.
Search engines use complex mathematical algorithms to guess 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.

As digital marketing continues to grow and develop, brands take great advantage of using technology and the Internet as a successful way to communicate with its clients and allows them to increase the reach of who they can interact with and how they go about doing so,.[2] There are however disadvantages that are not commonly looked into due to how much a business relies on it. It is important for marketers to take into consideration both advantages and disadvantages of digital marketing when considering their marketing strategy and business goals.
This is so funny. Google stifled the notion of linking to “great content” the minute they let on to how important linking was to passing pagerank. In effect, the importance of links has indeed led to pagerank hoarding and link commoditization which in turn leads to all of the things google doesn’t like such as spammy links, link farms, link selling, link buying, etc. What you end up with is a system, much like our economic system, where the rich get richer and poor get poorer. Nobody has a problem linking to CNN, as if they really needed the links. On the flip side who wants make a dofollow link to a site that’s 2 days old, great content or not when you can provide your visitors a nofollow link which is just as valuable to them. The whole notion of benefiting from a quality outbound link is a joke, the outbound linker receives 0 benefit when you factor the outflow of pagerank.
For example this page. My program found almost 400 nofollow links on this page. (Each comment has 3). And then you have almost 60 navigation links. My real question is how much percentage of the PageRank on this page gets distributed to the 9 real links in the article? If it is a division of 469 which some SEO experts now are claiming it is really disturbing. You won’t earn much from the links if you follow what I am saying.
If you’re not getting the clicks… you may need to invest more money per click. As you might expect, there are algorithms in play for SEM. Also, the more you pay, the more likely you are to be served with high-value (in terms of potential spending with your business) clicks. Or, you may just need to re-evaluate your keyphrase – maybe it’s not as popular as the figures, provided by Google Adwords, suggest?
Honestly, this I’ve read your blog for about 4 or 5 years now and the more I read the less I cared about creating new content online because it feels like even following the “Google Rules” still isn’t the way to go because unlike standards, there is no standard. You guys can change your mind whenever you feel like and I can become completely screwed. So screw it. I’m done trying to get Google to find my site. With Twitter and other outlets and 60% of all Google usage is not even finding site but Spell Check, I don’t care anymore.
“With 150 million pages, the Web had 1.7 billion edges (links).” Kevin Heisler, that ratio holds true pretty well as the web gets bigger. A good rule of thumb is that the number of links is about 10x the number of pages. I agree that it’s pretty tragic that Rajeev Motwani was a co-author of many of those early papers. I got to talk to Rajeev a little bit at Google, and he was a truly decent and generous man. What has heartened me is to see all the people that he helped, and to see those people pay their respects online. No worries on the Consumer WebWatch–I’m a big fan of Consumer WebWatch, and somehow I just missed their blog. I just want to reiterate that even though this feels like a huge change to a certain segment of SEOs, in practical terms this change really doesn’t affect rankings very much at all.

Many blogging software packages automatically nofollow user comments, but those that don't can most likely be manually edited to do this. This advice also goes for other areas of your site that may involve user-generated content, such as guest books, forums, shout-boards, referrer listings, etc. If you're willing to vouch for links added by third parties (for example, if a commenter is trusted on your site), then there's no need to use nofollow on links; however, linking to sites that Google considers spammy can affect the reputation of your own site. The Webmaster Help Center has more tips on avoiding comment spam39, for example by using CAPTCHAs and turning on comment moderation.
But I also don’t wanna lose PageRank on every comment with a link… If I can give PageRank and lose none, I wanna let the comment there, even without nofollow. But if I lose PageRank on every link, even inside original post, EVEN MORE if nofollow also takes PageRank out of me, I may just start using JavaScript or simple text without anchor for links… I definetely don’t like this idea, but I dislike even more losing PageRank on each outlink on my site. I’d just link top quality sites that I actively wanna vote for Search Engines.

I first discovered Sharpe years ago online. His story was one of the most sincere and intriguing tales that any one individual could convey. It was real. It was heartfelt. It was passionate. And it was a story of rockbottom failure. It encompassed a journey that mentally, emotionally and spiritually crippled him in the early years of his life. As someone who left home at the age of 14, had a child at 16, became addicted to heroin at 20 and clean four long years later, the cards were definitely stacked up against him.
Suppose instead that page B had a link to pages C and A, page C had a link to page A, and page D had links to all three pages. Thus, upon the first iteration, page B would transfer half of its existing value, or 0.125, to page A and the other half, or 0.125, to page C. Page C would transfer all of its existing value, 0.25, to the only page it links to, A. Since D had three outbound links, it would transfer one third of its existing value, or approximately 0.083, to A. At the completion of this iteration, page A will have a PageRank of approximately 0.458.

Google PageRank (Google PR) is one of the methods Google uses to determine a page's relevance or importance. Important pages receive a higher PageRank and are more likely to appear at the top of the search results. Google PageRank (PR) is a measure from 0 - 10. Google Pagerank is based on backlinks. The more quality backlinks the higher Google Pagerank. Improving your Google page rank (building QUALITY backlinks ) is very important if you want to improve your search engine rankings.

As I was telling Norman above, these days what we’ve come to call content marketing is really a big part of “link building.” You can’t buy links, and “you link to me I’ll link to you” requests often land on deaf ears. Its really all about creating high quality content (videos, images, written blog posts) that appeals to the needs/wants of your target market, and then naturally earning inbound links from sources that truly find what you have to offer worth referencing.
PageRank is a link analysis algorithm and it assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is referred to as the PageRank of E and denoted by {\displaystyle PR(E).} Other factors like Author Rank can contribute to the importance of an entity.
