Most people who used the Google Toolbar probably never went through the effort of enabling the PageRank meter, which Google offered as an incentive to web surfers, a way for them to understand the quality of pages encountered when browsing (and a way for Google to understand what people were viewing beyond Google itself). But one group was very inclined to make the effort: SEOs.
There are simple and fast random walk-based distributed algorithms for computing PageRank of nodes in a network.[33] They present a simple algorithm that takes {\displaystyle O(\log n/\epsilon )}  rounds with high probability on any graph (directed or undirected), where n is the network size and {\displaystyle \epsilon }  is the reset probability ( {\displaystyle 1-\epsilon } is also called as damping factor) used in the PageRank computation. They also present a faster algorithm that takes {\displaystyle O({\sqrt {\log n}}/\epsilon )}  rounds in undirected graphs. Both of the above algorithms are scalable, as each node processes and sends only small (polylogarithmic in n, the network size) number of bits per round.


###### Example: A blogger John Doe writes a very interesting article about a sports event. Another blogger Samantha Smith doesn’t agree with John’s article and writes about it in another article for an online magazine. She links to John’s article, so that her readers can understand both point of views. John’s blog gets a valuable backlink. On the other hand, Samantha’s article gets popular and many other websites link to her article. Samantha’s website gets many new backlinks. Even though John only got one backlink for his article, the value of his backlink is increased by the backlinks Samantha’s article generated.

I don’t get it, it seems Google is constantly making rules & regulations as they see fit. I don’t try to “manipulate” any links we have on our site or any clients we work for. Links take time period. No way around it. But, now this explanation gives more fuel to all the Google bashers out there. I recently read an article about Guy Kawasaki has been “loaned” one, two, three cars in three years & is still within Google’s guidelines? Makes me wonder how many rules and regulations are broken. My take is do your job right, and don’t worry what Google is doing. If content is King then everything will fall into place naturally.
Understanding Mobiles: Understanding mobile devices is a significant aspect of digital marketing because smartphones and tablets are now responsible for 64% of the time US consumers are online (Whiteside, 2016).[42] Apps provide a big opportunity as well as challenge for the marketers because firstly the app needs to be downloaded and secondly the person needs to actually use it. This may be difficult as ‘half the time spent on smartphone apps occurs on the individuals single most used app, and almost 85% of their time on the top four rated apps’ (Whiteside, 2016).[42] Mobile advertising can assist in achieving a variety of commercial objectives and it is effective due to taking over the entire screen, and voice or status is likely to be considered highly; although the message must not be seen or thought of as intrusive (Whiteside, 2016).[42] Disadvantages of digital media used on mobile devices also include limited creative capabilities, and reach. Although there are many positive aspects including the users entitlement to select product information, digital media creating a flexible message platform and there is potential for direct selling (Belch & Belch, 2012).[44]
As of October 2018 almost 4.2 billion people were active internet users and 3.4 billion were social media users (Statista). China, India and the United States rank ahead all other countries in terms of internet users. This gives a marketer an unprecedented number of customers to reach with product and service offerings, available 24 hours a day, seven days a week. The interactive nature of the internet facilitates immediate communication between businesses and consumers, allowing businesses to respond quickly to the needs of consumers and changes in the marketplace.
Moreover, the PageRank mechanism is entirely general, so it can applied to any graph or network in any field. Currently, the PR formula is used in bibliometrics, social and information network analysis, and for link prediction and recommendation. It's even used for system analysis of road networks, as well as biology, chemistry, neuroscience, and physics.

Page Structure - The third core component of SEO is page structure. Because web pages are written in HTML, how the HTML code is structured can impact a search engine’s ability to evaluate a page. Including relevant keywords in the title, URL, and headers of the page and making sure that a site is crawlable are actions that site owners can take to improve the SEO of their site.
Under Armour came up with the hashtag “I Will What I Want” to encourage powerful athletic women to achieve their dreams despite any opposition they might face. The hashtag, first used by American Ballet Theatre ballerina soloist Misty Copeland, blew up on Facebook after supermodel Gisele Bündchen used it in one of her Facebook posts. Many other female athletes have also used the hashtag.
Matt, this is an excellent summary. I finally got around to reading “The Search” by John Battelle and it was very enlightening to understand much of the academia behind what led to the creation of Backrub.. er Google.Looking at how many times the project was almost shutdown due to bandwidth consumption (> 50% of what the university could offer at times) as well as webmasters being concerned that their pages would be stolen and recreated. It’s so interesting to see that issues we see today are some of the same ones that Larry and Sergey were dealing with back then. As always, thanks for the great read Matt!
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 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.
Positioning of a webpage on Google SERPs for a keyword depends on relevance and reputation, also known as authority and popularity. PageRank is Google's indication of its assessment of the reputation of a webpage: It is non-keyword specific. Google uses a combination of webpage and website authority to determine the overall authority of a webpage competing for a keyword.[36] The PageRank of the HomePage of a website is the best indication Google offers for website authority.[37]
I work on a site that allows users to find what they are looking for by clicking links that take them deeper and deeper into the site hierarchy. Content can be categorised in lots of different ways. After about three steps the difference between the results pages shown is of significance to a user but not to a search engine. I was about to add nofollow to links that took the browser deeper than 3 levels but after this announcement I won’t be…

A breadcrumb is a row of internal links at the top or bottom of the page that allows visitors to quickly navigate back to a previous section or the root page. Many breadcrumbs have the most general page (usually the root page) as the first, leftmost link and list the more specific sections out to the right. We recommend using breadcrumb structured data markup28 when showing breadcrumbs.
