Note that as the number of pages on the web increases, so does the total PageRank on the web, and as the total PageRank increases, the positions of the divisions in the overall scale must change. As a result, some pages drop a toolbar point for no ‘apparent’ reason. If the page’s actual PageRank was only just above a division in the scale, the addition of new pages to the web would cause the division to move up slightly and the page would end up just below the division. Google’s index is always increasing and they re-evaluate each of the pages on more or less a monthly basis. It’s known as the “Google dance”. When the dance is over, some pages will have dropped a toolbar point. A number of new pages might be all that is needed to get the point back after the next dance.
If someone clicks on your PPC listing, they arrive at your website on a page you’ve selected, and you are charged an amount no more than what you bid. So, if you bid $1.50 maximum on the keyword ‘widgets’, and that’s the highest bid, you’ll probably show up first in line. If 100 people click on your PPC listing, then the search engine or PPC service will charge you a maximum of $150.00.
Large web pages are far less likely to be relevant to your query than smaller pages. For the sake of efficiency, Google searches only the first 101 kilobytes (approximately 17,000 words) of a web page and the first 120 kilobytes of a pdf file. Assuming 15 words per line and 50 lines per page, Google searches the first 22 pages of a web page and the first 26 pages of a pdf file. If a page is larger, Google will list the page as being 101 kilobytes or 120 kilobytes for a pdf file. This means that Google’s results won’t reference any part of a web page beyond its first 101 kilobytes or any part of a pdf file beyond the first 120 kilobytes.
Customers are often researching online and then buying in stores and also browsing in stores and then searching for other options online. Online customer research into products is particularly popular for higher-priced items as well as consumable goods like groceries and makeup. Consumers are increasingly using the Internet to look up product information, compare prices, and search for deals and promotions.
6. Measurement and analysis. You won’t get far in SEO unless you know how to measure your results, interpret those results, and use your analysis to make meaningful changes to your approach. The best tool for the job is still Google Analytics, especially if you’re new to the game. Spend some time experimenting with different metrics and reports, and read up on Analytics knowledge base articles. There’s a deep world to dive into.
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.
Assume a small universe of four web pages: A, B, C and D. Links from a page to itself, or multiple outbound links from one single page to another single page, are ignored. PageRank is initialized to the same value for all pages. In the original form of PageRank, the sum of PageRank over all pages was the total number of pages on the web at that time, so each page in this example would have an initial value of 1. However, later versions of PageRank, and the remainder of this section, assume a probability distribution between 0 and 1. Hence the initial value for each page in this example is 0.25.
Most pay per click advertising requires that you write a couple of short, descriptive phrases about your service. Don’t underestimate the importance of this – make sure, at a minimum, that your grammar, spelling, and overall language is correct and appropriate for your audience. Also, verify that your language adheres to the rules enforced by the pay per click platform – Google, for example, won’t allow ads with superlatives (“the best,” “the greatest,” etc.), with repeated keywords, or with excessive capitalization.
Lost IS (budget), aka “budget too low” – Do your campaigns have set daily/monthly budget caps? If so, are your campaigns hitting their caps frequently? Budget caps help pace PPC spend but can also suppress yours Ads from being shown if set too low. Google calls it “throttling” where Adwords won’t serve up ads every time they are eligible to be shown in an effort to allow your account to evenly pace through the daily budget.

 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.
I think Google will always be working to discern and deliver “quality, trustworthy” content and I think analyzing inbound links as endorsements is a solid tool the SE won’t be sunsetting anytime soon. Why would they? If the president of the United States links to your page that is undoubtedly an endorsement that tells Google you’re a legitimate trusted source. I know that is an extreme example, but I think it illustrates the principals of a linking-as-endorsement model well.

Facebook Ads and Instagram Ads take relevance and ad engagement into consideration. Ads that perform well are given a higher relevance score and are given more impressions at a cheaper price than ads with low relevance. Similarly, AdWords assigns ads a quality score based on factors like keyword relevance and landing page quality that can affect how much you pay for each click.
(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.
For instance, if you have an article called “How To Do Keyword Research,” you can help reinforce to Google the relevance of this page for the subject/phrase “keyword research” by linking from an article reviewing a keyword research tool to your How To Do Keyword Research article. This linking strategy is part of effective siloing, which helps clarify your main website themes.
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  that were used in the creation of Google is Efficient crawling through URL ordering, 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.

Webmasters and content providers began optimizing websites for search engines in the mid-1990s, as the first search engines were cataloging the early Web. Initially, all webmasters needed only to submit the address of a page, or URL, to the various engines which would send a "spider" to "crawl" that page, extract links to other pages from it, and return information found on the page to be indexed. The process involves a search engine spider downloading a page and storing it on the search engine's own server. A second program, known as an indexer, extracts information about the page, such as the words it contains, where they are located, and any weight for specific words, as well as all links the page contains. All of this information is then placed into a scheduler for crawling at a later date.
