(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.
PageRank is only a score that represents the importance of a page, as Google estimates it (By the way, that estimate of importance is considered to be Google’s opinion and protected in the US by the First Amendment. When Google was once sued over altering PageRank scores for some sites, a US court ruled: “PageRanks are opinions — opinions of the significance of particular Web sites as they correspond to a search query….the court concludes Google’s PageRanks are entitled to full constitutional protection.)
In the 2000s, with more and more Internet users and the birth of iPhone, customers started searching products and making decisions about their needs online first, instead of consulting a salesperson, which created a new problem for the marketing department of a company. In addition, a survey in 2000 in the United Kingdom found that most retailers had not registered their own domain address.These problems made marketers find the digital ways for market development.
From an SEO perspective, there is no difference between the best and worst content on the Internet if it is not linkable. If people can’t link to it, search engines will be very unlikely to rank it, and as a result the content won’t drive traffic to the given website. Unfortunately, this happens a lot more often than one might think. A few examples of this include: AJAX-powered image slide shows, content only accessible after logging in, and content that can't be reproduced or shared. Content that doesn't supply a demand or is not linkable is bad in the eyes of the search engines—and most likely some people, too.
The Google toolbar range is from 1 to 10. (They sometimes show 0, but that figure isn’t believed to be a PageRank calculation result). What Google does is divide the full range of actual PageRanks on the web into 10 parts – each part is represented by a value as shown in the toolbar. So the toolbar values only show what part of the overall range a page’s PageRank is in, and not the actual PageRank itself. The numbers in the toolbar are just labels.
More specifically, who gets to appear on the page is based on and advertiser’s Ad Rank, a metric calculated by multiplying two key factors – CPC Bid (the highest amount an advertiser is willing to spend) and Quality Score (a value that takes into account your click-through rate, relevance, and landing page quality). This system allows winning advertisers to reach potential customers at a cost that fits their budget. It’s essentially a kind of auction. The below infographic illustrates how this auction system works.
2018 Update: Since 2012 we have run an informal poll to see how widely used digital marketing strategies are. The results have shown some big improvements over the years.

Website owners recognized the value of a high ranking and visibility in search engine results, 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. On May 2, 2007, Jason Gambert attempted to trademark the term SEO by convincing the Trademark Office in Arizona that SEO is a "process" involving manipulation of keywords and not a "marketing service."
