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.
Now you know the difference between impressions and Impression Share (IS). Regularly monitor your Impression Share metrics and quickly fix issues as they arise. Low Impression Share hurts your chances at success by allowing your competitors to gain greater market share. Chances are, your competitors are already closely monitoring their IS and actively optimizing to 100% Impression Share. PPC is a dynamic platform – always look for opportunities to make gains over your competitors.
Google spiders the directories just like any other site and their pages have decent PageRank and so they are good inbound links to have. In the case of the ODP, Google’s directory is a copy of the ODP directory. Each time that sites are added and dropped from the ODP, they are added and dropped from Google’s directory when they next update it. The entry in Google’s directory is yet another good, PageRank boosting, inbound link. Also, the ODP data is used for searches on a myriad of websites – more inbound links!
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.[10][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.[11] 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.[12]

Of course, important pages mean nothing to you if they don’t match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all dozens of aspects of the page’s content (and the content of the pages linking to it) to determine if it’s a good match for your query.


Whether or not the overall range is divided into 10 equal parts is a matter for debate – Google aren’t saying. But because it is much harder to move up a toolbar point at the higher end than it is at the lower end, many people (including me) believe that the divisions are based on a logarithmic scale, or something very similar, rather than the equal divisions of a linear scale.
In the past, the PageRank shown in the Toolbar was easily manipulated. Redirection from one page to another, either via a HTTP 302 response or a "Refresh" meta tag, caused the source page to acquire the PageRank of the destination page. Hence, a new page with PR 0 and no incoming links could have acquired PR 10 by redirecting to the Google home page. This spoofing technique was a known vulnerability. Spoofing can generally be detected by performing a Google search for a source URL; if the URL of an entirely different site is displayed in the results, the latter URL may represent the destination of a redirection.

The content page in this figure is considered good for several reasons. First, the content itself is unique on the Internet (which makes it worthwhile for search engines to rank well) and covers a specific bit of information in a lot of depth. If a searcher had question about Super Mario World, there is a good chance, that this page would answer their query.


PPC stands for “pay-per-click”. PPC advertising platforms allow you to create content, show it to relevant users and then charge you for specific actions taken on the ad. In many cases, you’ll be paying for ad clicks that take users to your site, but on some platforms you can also pay for other actions like impressions, video views and on-site engagements.
Digital marketing is defined by the use of numerous digital tactics and channels to connect with customers where they spend much of their time: online. From the website itself to a business's online branding assets -- digital advertising, email marketing, online brochures, and beyond -- there's a spectrum of tactics that fall under the umbrella of "digital marketing."
A more intelligent surfer that probabilistically hops from page to page depending on the content of the pages and query terms the surfer that it is looking for. This model is based on a query-dependent PageRank score of a page which as the name suggests is also a function of query. When given a multiple-term query, Q={q1,q2,…}, the surfer selects a q according to some probability distribution, P(q) and uses that term to guide its behavior for a large number of steps. It then selects another term according to the distribution to determine its behavior, and so on. The resulting distribution over visited web pages is QD-PageRank.[39]

Ad extensions are additional links and details that show supplementary information about your business to enhance the basic PPC ads. Certain ad extensions are manual choices, which you can control. Search engines may also automatically generate some ad extensions. The main advantage of ad extensions is that they help improve the click-thru-rate (CTR) of the ad headline because the ads are larger in size and therefore more prominent on the search engine results pages (SERPs). There are many ad extensions.
Create, develop and enhance your relationships with influencers, bloggers, consultants, and editors. In every industry, you should already know that there are a number of reputable figures that people listen to and trust. Take advantage to develop relationships with them, because they’ll be able to enhance distribution of your content, and include quality backlinks to your blog.
What seems to be happening is that the toolbar looks at the URL of the page the browser is displaying and strips off everything down the last “/” (i.e. it goes to the “parent” page in URL terms). If Google has a Toolbar PR for that parent then it subtracts 1 and shows that as the Toolbar PR for this page. If there’s no PR for the parent it goes to the parent’s parent’s page, but subtracting 2, and so on all the way up to the root of your site.  If it can’t find a Toolbar PR to display in this way, that is if it doesn’t find a page with a real calculated PR, then the bar is greyed out.
Nathan: The comment by Mansi Rana helps answer your question. The fact is, the PageRank scores that were visible in the Google Toolbar hadn’t been updated in a long time (2+ YEARS), so they were probably getting more and more out-of-date anyway. The main reason Google would make them disappear, though, is that Google wants website owners to focus on the user and on quality content, not on trying to game the system with links.
It is clear that something new should emerge to cover that unfollow emptiness. Here and there it is believed that some search engines may use so-called implied links to rank the page. Implied links are, for example, references to your brand. They usually come with a tone: positive, neutral, or negative. The tone defines the reputation of your site. This reputation serves as a ranking signal to search engines.
While ordinary users were not that interested in pages' scores, SEOs of a different caliber felt that this was a great opportunity to make a difference for their customers. This obsession of SEOs with PageRank made everyone feel that this ranking signal is more or less the only important one. In spite of the fact that pages with a lower PR score can beat those with a higher score! What did we receive then, as a result?
The development of digital marketing is inseparable from technology development. One of the key points in the start of was in 1971, where Ray Tomlinson sent the very first email and his technology set the platform to allow people to send and receive files through different machines [8]. However, the more recognisable period as being the start of Digital Marketing is 1990 as this was where the Archie search engine was created as an index for FTP sites. In the 1980s, the storage capacity of computer was already big enough to store huge volumes of customer information. Companies started choosing online techniques, such as database marketing, rather than limited list broker.[9] This kind of databases allowed companies to track customers' information more effectively, thus transforming the relationship between buyer and seller. However, the manual process was not so efficient.
And that sense of context has grown from simple matching of words, and then of phrases, to the matching of ideas. And the meanings of those ideas change over time and context. Successful matching can be crowd sourced, what are others currently searching for and clicking on, when one enters keywords related to those other searches. And the crowd sourcing may be focused based upon one's own social networking.

(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.

By relying so much on factors such as keyword density which were exclusively within a webmaster's control, early search engines suffered from abuse and ranking manipulation. To provide better results to their users, search engines had to adapt to ensure their results pages showed the most relevant search results, rather than unrelated pages stuffed with numerous keywords by unscrupulous webmasters. This meant moving away from heavy reliance on term density to a more holistic process for scoring semantic signals.[13] Since the success and popularity of a search engine is determined by its ability to produce the most relevant results to any given search, poor quality or irrelevant search results could lead users to find other search sources. Search engines responded by developing more complex ranking algorithms, taking into account additional factors that were more difficult for webmasters to manipulate. In 2005, an annual conference, AIRWeb, Adversarial Information Retrieval on the Web was created to bring together practitioners and researchers concerned with search engine optimization and related topics.[14]
