Algorithm used by Google Search to rank web pages PageRank (PR) is an algorithm used by Google Search to rank web pages in their search engine results. It is named after both the term "web page" and co-founder Larry Page. PageRank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is. Currently, PageRank is not the only algorithm used by Google to order search results, but it is the first algorithm that was used by the company, and it is the best known.[2][3] As of September 24, 2019, all patents associated with PageRank have expired.[4] Description[edit] A PageRank results from a mathematical algorithm based on the webgraph, created by all World Wide Web pages as nodes and hyperlinks as edges, taking into consideration authority hubs such as or History[edit] The eigenvalue problem behind PageRank's algorithm was independently rediscovered and reused in many scoring problems.

New York Times Exposes J.C. Penney Link Scheme That Causes Plummeting Rankings in Google Today, the New York Times published an article about a search engine optimization investigation of J.C. Penney. Perplexed by how well did in unpaid (organic) search results for practically everything the retailer sold, they asked someone familiar with the world of search engine optimization (SEO) to look into it a bit more. The investigation found that thousands of seemingly unrelated web sites (many that seemed to contain only links) were linking to the J.C. The New York Times presented their findings to Google. J.C. So where did J.C. “Link Schemes” and the Google Webmaster Guidelines The web is big. Google was launched on a foundation of PageRank: the idea that people link to things they like and find valuable, so a page with a lot of links to it is probably more useful than a page without very many links. Over time, as site owners realized how valuable it was to rank well in Google search results, some began hatching “link schemes”. Everyone, that is, except Google.

How Google made the world go viral The first thing ever searched on Google was the name Gerhard Casper, a former Stanford president. As the story goes, in 1998, Larry Page and Sergey Brin demoed Google for computer scientist John Hennessy. They searched Casper’s name on both AltaVista and Google. The former pulled up results for Casper the Friendly Ghost; the latter pulled up information on Gerhard Casper the person. What made Google’s results different from AltaVista’s was its algorithm, PageRank, which organized results based on the amount of links between pages. Google officially went online later in 1998. This year, The Verge is exploring how Google Search has reshaped the web into a place for robots — and how the emergence of AI threatens Google itself. There is a growing chorus of complaints that Google is not as accurate, as competent, as dedicated to search as it once was. For two decades, Google Search was the largely invisible force that determined the ebb and flow of online content. But it wasn’t an anomaly.

Google Raters - All About Google Quality Raters Wow, my post about how Google makes algorithm changes sure got a LOT of attention. While I happened to think the post itself was pretty darn informative (if I can be so humble…lol), it turns out that the majority of folks visiting just wanted a copy of the 2011 Google Quality Raters Handbook. Makes sense, but as most know by now, I was contacted by Google and had to stop sharing and linking to that document. So, let’s move on and talk about these Google Quality Raters. Google Quality Raters are out there rating not only organic search results, but also Google ads (AdWords) and Videos, and probably more things but those are the three types of raters I am sure of. There is a good forum out there that is all “Quality Raters” info and discussion. The Raters I will be talking about today are the ones that rate the organic results – called Search Quality Raters. What Is a Google Search Quality Rater? “There are a few names for this position. These quality raters are not new for Google. 1. 2.

Happiness is peace, it’s not pleasure. #willsmithmotivation #willsmith... | Happy Quotes | TikTok The Fresh Rank Algorithm, Is It More Important Than PageRank First of all let me confess the term ‘fresh rank’ has been stolen from fellow SEO blogger Justin Briggs, I am going to refer to one of his excellent posts throughout the rest of this one. You will no doubt know about Google’s new QDF upgrade, an algorithm tweak designed to get you to ‘fresh’ content quicker, rather than bringing up old static results. You can see an example of it here; They’re not site links but links to fresh content on the BBC for the search term ‘football’. Google has stated that this affects around 35% of search queries, don’t get that mixed up with searches. 1) How does Google decide what is fresh? 2) Is the link graph involved when deciding ‘freshness’? 3) How do links from these ‘fresh’ pages influence rankings for the taget website? I wrote a really short post a few months ago based on fresh links vs text links vs links placed in old content. How Does Google Determine Freshness? Document Discovery Proportion of Change Fresh Rank Is Freshness More Influential Than PageRank

Howard Rheingold's insight:

Every time you Google, you are using an augmented collective intelligence engine. PageRank is the algorithm that weights the inbound links to web pages as "votes" for that page's significance. Certainly no blogger thinks "I'm making Google more intelligent and contributing to its value" when adding a link to a website. More likely, they think "this is a valuable link for the attention of my public." By figuring out how to measure the informational value of websites through a mathematical manipulation of its inbound links, Google created a collective intelligence engine (and, to the benefit of Google's stockholders, created an attention magnet for displaying advertising messages -- a case of a public good that is also a concentrator of private wealth. by noosquest Mar 30
