You can confer some of your site's reputation to another site when your site links to it. Sometimes users can take advantage of this by adding links to their own site in your comment sections or message boards. Or sometimes you might mention a site in a negative way and don't want to confer any of your reputation upon it. For example, imagine that you're writing a blog post on the topic of comment spamming and you want to call out a site that recently comment spammed your blog. You want to warn others of the site, so you include the link to it in your content; however, you certainly don't want to give the site some of your reputation from your link. This would be a good time to use nofollow.
Get a link to your pages from an high PR page and yes, some of that PageRank importance is transmitted to your page. But that’s doesn’t take into account the context of the link — the words in the link — the anchor text. If you don’t understand anchor text, Google Now Reporting Anchor Text Phrases from me last month will take you by the hand and explain it more.
Google's core algorithms and its propensity to shroud its data in layers of obscurity is not something new. However, it is critical to any understanding of marketing on the internet simply because this visibility is at the heart of everything else that you do. Forget about social media and other forms of marketing for the time being. Search engine optimization (SEO) offers up the proverbial key to near-limitless amounts of traffic on the web.
While there are several platforms for doing this, clearly YouTube is the most popular for doing this. However, video marketing is also a great form of both content marketing and SEO on its own. It can help to provide visibility for several different ventures, and if the video is valuable enough in its message and content, it will be shared and liked by droves, pushing up the authority of that video through the roof.
The amount of link juice passed depends on two things: the number of PageRank points of the webpage housing the link, and the total number of links on the webpage that are passing PageRank. It’s worth noting here that while Google will give every website a public-facing PageRank score that is between 1 and 10, the “points” each page accumulates from the link juice passed by high-value inbound links can — and do — significantly surpass ten. For instance, webpages on the most powerful and significant websites can pass link juice points in the hundreds or thousands. To keep the rating system concise, Google uses a lot of math to correlate very large (and very small) PageRank values with a neat and clean 0 to 10 rating scale.
Now that you know that backlinks are important, how do you acquire links to your site? Link building is still critical to the success of any SEO campaign when it comes to ranking organically. Backlinks today are much different than when they were built in 7-8 years back. Simply having thousands of backlinks or only have link from one website isn’t going to affect your rank position. There are also many ways to manage and understand your backlink profile. Majestic, Buzzstream, and Moz offer tools to help you manage and optimize your link profile. seoClarity offers an integration with Majestic, the largest link index database, that integrates link profile management into your entire SEO lifecycle.
How many times do we need to repeat the calculation for big networks? That’s a difficult question; for a network as large as the World Wide Web it can be many millions of iterations! The “damping factor” is quite subtle. If it’s too high then it takes ages for the numbers to settle, if it’s too low then you get repeated over-shoot, both above and below the average - the numbers just swing about the average like a pendulum and never settle down.
Journalists and writers are always on the lookout for experts to contribute quotes for their articles. Some (but not all) will include backlinks to their sources’ websites. Getting quotes in media outlets is a great way to not only get backlinks, but also build credibility within your industry. Even in instances where you don't get backlinks, this profile page for PMM's CEO Josh Rubin is a good example of how you can showcase your media appearances - something which both Google and your clients value when it comes to evaluating your authority.
“So what happens when you have a page with “ten PageRank points” and ten outgoing links, and five of those links are nofollowed? Let’s leave aside the decay factor to focus on the core part of the question. Originally, the five links without nofollow would have flowed two points of PageRank each (in essence, the nofollowed links didn’t count toward the denominator when dividing PageRank by the outdegree of the page). More than a year ago, Google changed how the PageRank flows so that the five links without nofollow would flow one point of PageRank each.”
The name "PageRank" plays off of the name of developer Larry Page, as well as of the concept of a web page. The word is a trademark of Google, and the PageRank process has been patented (U.S. Patent 6,285,999). However, the patent is assigned to Stanford University and not to Google. Google has exclusive license rights on the patent from Stanford University. The university received 1.8 million shares of Google in exchange for use of the patent; it sold the shares in 2005 for $336 million.
I think it’s important to remember that the majority of website owners are NOT at all technical and savvy as to how this whole system works when it comes to SEO, but they still get along and do their best to put something worthwhile on the net. Unfortunately this same majority can so often damage their website rankings without ever knowing it, and lead to an under-performing website as a result, regardless of the quality of their content. As I’ve learnt as a new website owner for the first time, there’s a lot more to running a website than just doing the right thing and trying to produce quality, when time and time again the experts in SEO always win out on the SERPs regardless of quality. One keyword phrase I searched on repeatedly over recent years resulted in the same EMPTY site being returned as the number one result, truly, it had NO content.
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.
