How many times do we need to repeat the calculation for big networks? That’s a difficult question; for a network as large as the World Wide Web it can be many millions of iterations! The “damping factor” is quite subtle. If it’s too high then it takes ages for the numbers to settle, if it’s too low then you get repeated over-shoot, both above and below the average - the numbers just swing about the average like a pendulum and never settle down.
All major crawler-based search engines leverage links from across of the web, but none of them report a static “importance” score in the way Google does via its Google Toolbar. That score, while a great resource for surfers, has also provided one of the few windows into how Google ranks web pages. Some webmasters, desperate to get inside Google, keep flying into that window like confused birds, smacking their heads and losing their orientation….
Remember, depending on your targeting methods, the placement might not be that important. If you’re targeting the user through interests or remarketing, the placement is just where that user visits. Of course, some sites will still perform better than others, but keep in mind which targeting method you’re using when evaluating placement performances.
For the examples, we are going to ignore that fact, mainly because other ‘Pagerank Explained’ type documents ignore it in the calculations, and it might be confusing when comparing documents. The calculator operates in two modes:- Simple and Real. In Simple mode, the calculations assume that all pages are in the Google index, whether or not any other pages link to them. In Real mode the calculations disregard unlinked-to pages. These examples show the results as calculated in Simple mode. pagerank, page rank

The PageRank algorithm outputs a probability distribution used to represent the likelihood that a person randomly clicking on links will arrive at any particular page. PageRank can be calculated for collections of documents of any size. It is assumed in several research papers that the distribution is evenly divided among all documents in the collection at the beginning of the computational process. The PageRank computations require several passes, called “iterations”, through the collection to adjust approximate PageRank values to more closely reflect the theoretical true value.

There are two primary models for determining pay-per-click: flat-rate and bid-based. In both cases, the advertiser must consider the potential value of a click from a given source. This value is based on the type of individual the advertiser is expecting to receive as a visitor to his or her website, and what the advertiser can gain from that visit, usually revenue, both in the short term as well as in the long term. As with other forms of advertising targeting is key, and factors that often play into PPC campaigns include the target's interest (often defined by a search term they have entered into a search engine, or the content of a page that they are browsing), intent (e.g., to purchase or not), location (for geo targeting), and the day and time that they are browsing.
Call extensions are available in both Google and Bing and give advertisers two possibilities. On mobile devices, call extensions supplement ads with the ability to click-to-call, giving mobile searchers an easy way to call the business. Keep in mind that call extensions are now part of AdWords’ dynamic ad extension options. In the event that calls are of no use to your business, consider opting out of this feature.
SEO – Search Engine Optimization is the practice of achieving a high rank in the SERPs without the use of paid ads. In other words, marketers create content that they think will rank well for a specific search term. Typically, they’ll also build a backlink profile to pass page rank from high authority sites to their own site in an effort to achieve a higher spot in the search results.
Early versions of search algorithms relied on webmaster-provided information such as the keyword meta tag or index files in engines like ALIWEB. Meta tags provide a guide to each page's content. Using metadata to index pages was found to be less than reliable, however, because the webmaster's choice of keywords in the meta tag could potentially be an inaccurate representation of the site's actual content. Inaccurate, incomplete, and inconsistent data in meta tags could and did cause pages to rank for irrelevant searches.[dubious – discuss] Web content providers also manipulated some attributes within the HTML source of a page in an attempt to rank well in search engines. By 1997, search engine designers recognized that webmasters were making efforts to rank well in their search engine, and that some webmasters were even manipulating their rankings in search results by stuffing pages with excessive or irrelevant keywords. Early search engines, such as Altavista and Infoseek, adjusted their algorithms to prevent webmasters from manipulating rankings.
