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.
(1 - d) - The (1 – d) bit at the beginning is a bit of probability math magic so the “sum of all web pages' PageRanks will be one”: it adds in the bit lost by the d(.... It also means that if a page has no links to it (no backlinks) even then it will still get a small PR of 0.15 (i.e. 1 – 0.85). (Aside: the Google paper says “the sum of all pages” but they mean the “the normalised sum” – otherwise known as “the average” to you and me.
Inclusion in Google's search results is free and easy; you don't even need to submit your site to Google. Google is a fully automated search engine that uses web crawlers to explore the web constantly, looking for sites to add to our index. In fact, the vast majority of sites listed in our results aren't manually submitted for inclusion, but found and added automatically when we crawl the web. Learn how Google discovers, crawls, and serves web pages.3
Brunson talks about this reverse engineering in his book called, Dot Com Secrets, a homage to the internet marketing industry, and quite possibly one of the best and most transparent books around in the field. Communication is what will bridge the divide between making no money and becoming a massive six or seven-figure earner. Be straight with people and learn to communicate effectively and understand every stage of the process and you'll prosper as an internet marketer.
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.
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 search engine results page (SERP) is the actual result returned by a search engine in response to a keyword query. The SERP consists of a list of links to web pages with associated text snippets. The SERP rank of a web page refers to the placement of the corresponding link on the SERP, where higher placement means higher SERP rank. The SERP rank of a web page is a function not only of its PageRank, but of a relatively large and continuously adjusted set of factors (over 200).[35] Search engine optimization (SEO) is aimed at influencing the SERP rank for a website or a set of web pages.
I like that you said you let PageRank flow freely throughout your site. I think that’s good and I’ve steered many friends and clients to using WordPress for their website for this very reason. With WordPress, it seems obvious that each piece of content has an actual home (perma links) and so it would seem logical that Google and other search engines will figure out that structure pretty easily.
I did this post because I wanted people to understand more about PageRank, how it works, and to clarify my answers at SMX Advanced. Yes, I would agree that Google itself solely decides how much PageRank will flow to each and every link on a particular page. But that’s no reason to make PageRank a complete black box; if I can help provide people with a more accurate mental model, overall I think that’s a good thing. For example, from your proposed paragraph I would strike the “The number of links doesn’t matter” sentence because most of the time the number of links do matter, and I’d prefer that people know that. I would agree with the rest of your paragraph explanation–which is why in my mind PageRank and our search result rankings qualifies as an opinion and not simply some rote computation. But just throwing out your single paragraph, while accurate (and a whole lot faster to write!), would have been deeply unsatisfying for a number of people who want to know more.
One final note is that if the links are not directly related to the subject, or you have no control over them, such as commentors’ website links, maybe you should consider putting them on another page, which links to your main content. That way you don’t leak page rank, and still gain hits from search results from the content of the comments. I may be missing something but this seems to mean that you can have your cake and eat it, and I don’t even think it is gaming the system or against the spirit of it. You might even gain a small sprinkling of page rank if the comment page accumulates any of it’s own.
The original Random Surfer PageRank patent from Stanford has expired. The Reasonable Surfer version of PageRank (assigned to Google) is newer than that one, and has been updated via a continuation patent at least once. The version of PageRank based upon a trusted seed set of sites (assigned to Google) has also been updated via a continuation patent and differs in many ways from the Stanford version of PageRank. It is likely that Google may be using one of the versions of PageRank that they have control over (the exclusive license to use Stanford’s version of PageRank has expired along with that patent). The updated versions of PageRank (reasonable surfer and Trusted Seeds approach) both are protected under present day patents assigned to Google, and both have been updated to reflect modern processes in how they are implemented. Because of their existence, and the expiration of the original, I would suggest that it is unlikely that the random surfer model-base PageRank is still being used.
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.
You should fix all errors which can impair users’ expectations. By hurting user experience, you endanger the organic growth of your traffic because Google will surely limit it. Do this task thoroughly and don’t be in a hurry, otherwise, you might learn that your backlinks don’t work. Be responsible for each decision and action. Search Engine Optimization (SEO) works better when the technical optimization of your site meets the standards.
Check your robots.txt file. Make sure you learn how to hide content you don’t want indexed from search engines and that search engines can find the content you do want indexed, too. (You will want to hide things such as repeat content, which can be penalized by search engines but is still necessary on your site). You’ll find a link to how to modify the robots.txt at the end of this article.

I personally nofollow links to my privacy policy and contact form. Even though these are excluded in robots.txt, I prefer that extra layer of protection so that the pages are not indexed. Anyone that has ever had their contact form blasted continuously by spammers knows what I mean. And yes, one could add the noindex meta tag. But let’s face it, not everyone is a skilled PHP programmer. On dynamic sites its not as simple as adding a meta tag…
Your customers, prospects, and partners are the lifeblood of of your business. You need to build your marketing strategy around them. Step 1 of marketing is understanding what your customers want, which can be challenging when you’re dealing with such a diverse audience. This chapter will walk you through (1) the process of building personal connections at scale and (2) crafting customer value propositions that funnel back to ROI for your company.

There are a few things to consider when beginning your backlink building campaign. It is helpful to keep track of your backlinks, to know which sites are linking back to you, and how the anchor text of the backlink incorporates keywords relating to your site. A tool to help you keep track of your backlinks is the Domain Stats Tool. This tool displays the backlinks of a domain in Google, Yahoo, and MSN. It will also tell you a few other details about your website, like your listings in the Open Directory, or DMOZ, from which Google regards backlinks highly important; Alexa traffic rank, and how many pages from your site that have been indexed, to name just a few.


There’s obviously a huge number of reasons why a website might link to another and not all of them fit into the categories above. A good rule of thumb on whether a link is valuable is to consider the quality of referral traffic (visitors that might click on the link to visit your website). If the site won’t send any visitors, or the audience is completely unrelated and irrelevant, then it might not really be a link that’s worth pursuing.

A Web crawler may use PageRank as one of a number of importance metrics it uses to determine which URL to visit during a crawl of the web. One of the early working papers[56] that were used in the creation of Google is Efficient crawling through URL ordering,[57] which discusses the use of a number of different importance metrics to determine how deeply, and how much of a site Google will crawl. PageRank is presented as one of a number of these importance metrics, though there are others listed such as the number of inbound and outbound links for a URL, and the distance from the root directory on a site to the URL.
The new digital era has enabled brands to selectively target their customers that may potentially be interested in their brand or based on previous browsing interests. Businesses can now use social media to select the age range, location, gender and interests of whom they would like their targeted post to be seen by. Furthermore, based on a customer's recent search history they can be ‘followed’ on the internet so they see advertisements from similar brands, products and services,[38] This allows businesses to target the specific customers that they know and feel will most benefit from their product or service, something that had limited capabilities up until the digital era.
But bear in mind that you can't guest post just anywhere and expect that it'll help. In fact, for years black hatters have perverted the value of guest posts by 'creating private blog networks,' which put out mass quantities of low-quality content for the sole purpose of exchanging backlinks. Google has caught on to this, and penalizes websites accordingly. So, you want to ensure that you only provide guest posts to reputable, respected websites that are relevant to your industry.
I think it is important you distinguish your advice about no-following INTERNAL links and no-following EXTERNAL links for user-generated content. Most popular UGC-heavy sites have no-followed links as they can’t possibly police them editorially & want to give some indication to the search engines that the links haven’t been editorially approved, but still might provide some user benefit.
“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.”
I agree that the more facts that you provide and if you were to provide the complete algorithm, people would abuse it but if it were available to everyone, would it not almost force people to implement better site building and navigation policies and white hat seo simply because everyone would have the same tools to work with and an absolute standard to adhere to.
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.
