These are paid advertisements via Google AdWords. You can differentiate these from organic (non-paid, earned) results because of the tiny yellow “ad” icon. Normally, you will also see paid ads at the top of the SERP as well. In this book, we are only talking about SEO for organic search results, not advertising through search engines. But it is important to understand the difference as a user, and as a search engine optimizer, as they can both be valuable.
PageRank is one of many, many factors used to produce search rankings. Highlighting PageRank in search results doesn’t help the searcher. That’s because Google uses another system to show the most important pages for a particular search you do. It lists them in order of importance for what you searched on. Adding PageRank scores to search results would just confuse people. They’d wonder why pages with lower scores were outranking higher scored pages.
(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.
Every SERP is unique, even for search queries performed on the same search engine using the same keywords or search queries. This is because virtually all search engines customize the experience for their users by presenting results based on a wide range of factors beyond their search terms, such as the user’s physical location, browsing history, and social settings. Two SERPs may appear identical, and contain many of the same results, but will often feature subtle differences.

Enhanced content such as images, videos, and product lists is another key part of SEO and can also help businesses rank higher on the SERP. Search engines are wary of local listings that are not rich with details about a business and favor results that are reliable, accurate, and consistent, and oftentimes this includes listings that include a lot of enhanced content.
AdWords Customer Match lets you target customers based on an initial list of e-mail addresses. Upload your list and you do things like serving different ads or bidding a different amount based on a shopper’s lifecycle stage. Serve one ad to an existing customer. Serve another to a subscriber. And so on. Facebook offers a similar tool, but AdWords was the first appearance of e-mail-driven customer matching in pay per click search.

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 [54] that were used in the creation of Google is Efficient crawling through URL ordering,[55] 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.

While working at a Fortune 100 company for nine years before moving to lead my current team, I became fascinated by customer behavior. What kinds of digital offerings most deeply engage customers in their digital lives? I started by looking at some case studies of the products, services, communications and experiences that had been embraced and adopted by customers during the first two decades of the internet. Over a period of seven years working on inbound marketing campaigns, what I found was a recurring pattern of three behaviors that drove the adoption of new digital experiences, which I call the three core behaviors of a network:
Automated rules are unique to AdWords. These rules are set using any number of performance criteria and can run on a schedule. The rules are meant to make account management less tedious, but should never fully replace the human touch. It is also worthwhile to set some type of performance threshold or safety rule to account for performance degradation.

He is the co-founder of Neil Patel Digital. The Wall Street Journal calls him a top influencer on the web, Forbes says he is one of the top 10 marketers, and Entrepreneur Magazine says he created one of the 100 most brilliant companies. Neil is a New York Times bestselling author and was recognized as a top 100 entrepreneur under the age of 30 by President Obama and a top 100 entrepreneur under the age of 35 by the United Nations.

For example, suppose you're a law firm targeting the phrase "divorce attorney" with a broad match ad. Your ad should appear on the results page for the search query "divorce attorney," but it could also show up for the phrases "reasons for divorce," "dui attorney" or "dealing with divorce for children." In these cases, you may be wasting money on irrelevant searches.
NOTE: You may be curious what your site’s or your competitor’s PR score is. But Google no longer reveals the PageRank score for websites. It used to display at the top of web browsers right in the Google Toolbar, but no more. And PR data is no longer available to developers through APIs, either. Even though it’s now hidden from public view, however, PageRank remains an important ingredient in Google’s secret ranking algorithms.
There are lots of ways you can optimize your digital marketing assets for mobile users, and when implementing any digital marketing strategy, it's hugely important to consider how the experience will translate on mobile devices. By ensuring this is always front-of-mind, you'll be creating digital experiences that work for your audience, and consequently achieve the results you're hoping for.

When would this be useful? If your site has a blog with public commenting turned on, links within those comments could pass your reputation to pages that you may not be comfortable vouching for. Blog comment areas on pages are highly susceptible to comment spam. Nofollowing these user-added links ensures that you're not giving your page's hard-earned reputation to a spammy site.

Notice that the description of the game is suspiciously similar to copy written by a marketing department. “Mario’s off on his biggest adventure ever, and this time he has brought a friend.” That is not the language that searchers write queries in, and it is not the type of message that is likely to answer a searcher's query. Compare this to the first sentence of the Wikipedia example: “Super Mario World is a platform game developed and published by Nintendo as a pack–in launch title for the Super Nintendo Entertainment System.”. In the poorly optimized example, all that is established by the first sentence is that someone or something called Mario is on an adventure that is bigger than his or her previous adventure (how do you quantify that?) and he or she is accompanied by an unnamed friend.
Google’s SERPs can show various elements: the search results themselves (so-called snippets), a knowledge graph, a featured snippet, an answer box, images, shopping results and more. Depending on the type of query and the data Google finds, some of these elements will show up. You can add data to your page, so Google can show a ‘rich’ snippet, providing more information about your product or recipe, for instance.
If you are serious about improving search traffic and are unfamiliar with SEO, we recommend reading this guide front-to-back. We've tried to make it as concise as possible and easy to understand. There's a printable PDF version for those who'd prefer, and dozens of linked-to resources on other sites and pages that are also worthy of your attention.

The box on the right side of this SERP is known as the Knowledge Graph (also sometimes called the Knowledge Box). This is a feature that Google introduced in 2012 that pulls data to commonly asked questions from sources across the web to provide concise answers to questions in one central location on the SERP. In this case, you can see a wide range of information about Abraham Lincoln, such as the date and place of his birth, his height, the date on which he was assassinated, his political affiliation, and the names of his children – many of which facts have their own links to the relevant pages.
[41] 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.

You should optimize your site to serve your users' needs. One of those users is a search engine, which helps other users discover your content. Search Engine Optimization is about helping search engines understand and present content. Your site may be smaller or larger than our example site and offer vastly different content, but the optimization topics we discuss below should apply to sites of all sizes and types. We hope our guide gives you some fresh ideas on how to improve your website, and we'd love to hear your questions, feedback, and success stories in the Google Webmaster Help Forum1.

Every time a search is initiated, Google digs into the pool of bidding AdWords advertisers and chooses a set of winners to appear in the ad space on its search results page. The “winners” are chosen based on a combination of factors, including the quality and relevance of their keywords and ad text, as well as the size of their keyword bids. For example, if WordStream bid on the keyword “PPC software,” our ad might show up in the very top spot on the Google results page.

Larry Page and Sergey Brin developed PageRank at Stanford University in 1996 as part of a research project about a new kind of search engine.[11] Sergey Brin had the idea that information on the web could be ordered in a hierarchy by "link popularity": a page ranks higher as there are more links to it.[12] Rajeev Motwani and Terry Winograd co-authored with Page and Brin the first paper about the project, describing PageRank and the initial prototype of the Google search engine, published in 1998:[5] shortly after, Page and Brin founded Google Inc., the company behind the Google search engine. While just one of many factors that determine the ranking of Google search results, PageRank continues to provide the basis for all of Google's web-search tools.[13]
SEO may generate an adequate return on investment. However, search engines are not paid for organic search traffic, their algorithms change, and there are no guarantees of continued referrals. Due to this lack of guarantees and certainty, a business that relies heavily on search engine traffic can suffer major losses if the search engines stop sending visitors.[60] Search engines can change their algorithms, impacting a website's placement, possibly resulting in a serious loss of traffic. According to Google's CEO, Eric Schmidt, in 2010, Google made over 500 algorithm changes – almost 1.5 per day.[61] It is considered wise business practice for website operators to liberate themselves from dependence on search engine traffic.[62] In addition to accessibility in terms of web crawlers (addressed above), user web accessibility has become increasingly important for SEO.
