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.
Contrary, in the first version of the algorithm the probability for the random surfer reaching a page is weighted by the total number of web pages. So, in this version PageRank is an expected value for the random surfer visiting a page, when he restarts this procedure as often as the web has pages. If the web had 100 pages and a page had a PageRank value of 2, the random surfer would reach that page in an average twice if he restarts 100 times.

Digital marketing is probably the fastest-changing marketing field out there: New tools are being built, more platforms emerge and more channels need to be included into your marketing plan. How not to get overwhelmed while staying on top of the latest marketing trends?

A key objective is engaging digital marketing customers and allowing them to interact with the brand through servicing and delivery of digital media. Information is easy to access at a fast rate through the use of digital communications. Users with access to the Internet can use many digital mediums, such as Facebook, YouTube, Forums, and Email etc. Through Digital communications it creates a Multi-communication channel where information can be quickly exchanged around the world by anyone without any regard to whom they are.[28] Social segregation plays no part through social mediums due to lack of face to face communication and information being wide spread instead to a selective audience. This interactive nature allows consumers create conversation in which the targeted audience is able to ask questions about the brand and get familiar with it which traditional forms of Marketing may not offer.[29]
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.

Just as some backlinks you earn are more valuable than others, links you create to other sites also differ in value. When linking out to an external site, the choices you make regarding the page from which you link (its page authority, content, search engine accessibility, and so on) the anchor text you use, whether you choose to follow or nofollow the link, and any other meta tags associated with the linking page can have a heavy impact on the value you confer.
The Open Directory Project (ODP) is a Web directory maintained by a large staff of volunteers. Each volunteer oversees a category, and together volunteers list and categorize Web sites into a huge, comprehensive directory. Because a real person evaluates and categorizes each page within the directory, search engines like Google use the ODP as a database for search results. Getting a site listed on the ODP often means it will show up on Google.

Another reason is that if you're using an image as a link, the alt text for that image will be treated similarly to the anchor text of a text link. However, we don't recommend using too many images for links in your site's navigation when text links could serve the same purpose. Lastly, optimizing your image filenames and alt text makes it easier for image search projects like Google Image Search to better understand your images.
Users will occasionally come to a page that doesn't exist on your site, either by following a broken link or typing in the wrong URL. Having a custom 404 page30 that kindly guides users back to a working page on your site can greatly improve a user's experience. Your 404 page should probably have a link back to your root page and could also provide links to popular or related content on your site. You can use Google Search Console to find the sources of URLs causing "not found" errors31.
I compare the latest Google search results to this: Mcdonalds is the most popular and is #1 in hamburgers… they dont taste that great but people still go there. BUT I bet you know a good burger joint down the road from Google that makes awesome burgers, 10X better than Mcdonalds, but “we” can not find that place because he does not have the resources or budget to market his burgers effectively.
Two weeks ago I changed a few internal anchor text links for a HTML SELECT Label in order to save some space in the menu bar. Today, when I saw in Google the Cache (text-version) page of my site I realized that all the links in the HTML SELECT Label cannot be followed. So I understand that Googlebot doesn’t follow this links and obviously there’s no inbound ‘link juice’. Is that so?
Website owners recognized the value of a high ranking and visibility in search engine results,[6] creating an opportunity for both white hat and black hat SEO practitioners. According to industry analyst Danny Sullivan, the phrase "search engine optimization" probably came into use in 1997. Sullivan credits Bruce Clay as one of the first people to popularize the term.[7] On May 2, 2007,[8] Jason Gambert attempted to trademark the term SEO by convincing the Trademark Office in Arizona[9] that SEO is a "process" involving manipulation of keywords and not a "marketing service."

[43] Katja Mayer views PageRank as a social network as it connects differing viewpoints and thoughts in a single place. People go to PageRank for information and are flooded with citations of other authors who also have an opinion on the topic. This creates a social aspect where everything can be discussed and collected to provoke thinking. There is a social relationship that exists between PageRank and the people who use it as it is constantly adapting and changing to the shifts in modern society. Viewing the relationship between PageRank and the individual through sociometry allows for an in-depth look at the connection that results.
One more important thing to keep in mind is that this factor is just part of the story about what helps pages to be displayed high in SERPs. Yes, it was the first one used by Google, but now there are lots of ranking factors, they all matter, and they all are taken into account for ranking. The most essential one is deemed content. You know this, content is king, there is no way around it. User experience is the new black (with the new Speed Update, it will become even more important).

Bob Dole (interesting name), you’re certainly welcome to use Bing if you prefer, but before you switch, you might check whether they do similar things. I know that Nate Buggia has strongly recommended not to bother with PageRank sculpting in the past, for example, or at least that was my perception from his comments at the last couple SMX Advanced conferences.
Search engine optimization (SEO) is the process of affecting the online visibility of a website or a web page in a web search engine's unpaid results—often referred to as "natural", "organic", or "earned" results. In general, the earlier (or higher ranked on the search results page), and more frequently a website appears in the search results list, the more visitors it will receive from the search engine's users; these visitors can then be converted into customers.[1] SEO may target different kinds of search, including image search, video search, academic search,[2] news search, and industry-specific vertical search engines. SEO differs from local search engine optimization in that the latter is focused on optimizing a business' online presence so that its web pages will be displayed by search engines when a user enters a local search for its products or services. The former instead is more focused on national or international searches.
These are ‘tit-for-tat’ links. For instance, you make a deal with your friend who has a business website to have him place a link to your website, and in exchange your website links back to his. In the dark ages of SEO, this used to be somewhat effective. But these days, Google considers such 'link exchanges' to be link schemes, and you may get hit with a penalty if you're excessive and obvious about it. This isn't to say that swapping links is always bad, but if your only motive is SEO, then odds are that you shouldn't do it.
Every mechanism or algorithm is good untill someone brake it. In my opinion as people tend to scam the search results, google is getting more and more consevative upon indexing and ranking search results. When I search a word or a phrase I see more wikipedia, amazon, google, youtube, etc. links returning my search, even the page name or headline does not cover the keywords in the phrase. I’m getting afraid that this may lead to an elitist web nature in the future.

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.
