How Does Google Work? Learn How Google Works: Search Engine + AdWords
The following infographic was created years ago when Google had a content-first focus on search. In the years since then, the rise of mobile devices has caused Google to shift to a user-first approach to search. We created a newer infographic to reflect the modern search landscape here.

Musings about librarianship: 6 common misconceptions when doing advanced Google Searching As librarians we are often called upon to teach not just library databases but also Google and Google Scholar. Unlike teaching other search tools, teaching Google is often tricky because unlike library databases where we can have insider access through our friendly product support representative as librarians we have no more or no less insight into Google which is legendary for being secretive. Still, given that Google has become synonymous with search we should be decently good at teaching it. I've noticed though, often when people teach Google, particularly advanced searching of Google, they fall prey to 2 main types of errors. The first type of error involved not keeping up to date and given the rapid speed that Google changes, we often end up teaching things that no longer work. The second type of error is perhaps more common to us librarians. Also the typical Google Scholar brings back estimated count of results. eg. The 6 are 1.

Webmapping Retour à la page d'accueil de la veille Le Webmapping désigne, au sens large, tout ce qui relève de la cartographie en ligne sur Internet. Sous ce terme générique, on englobe différents types d'applications cartographiques allant du simple visualiseur à l'outil de cartographie thématique, voire au SIG en ligne. Leur point commun est d'être accessible à travers un simple navigateur Internet.

PageRank Mathematical PageRanks for a simple network, expressed as percentages. (Google uses a logarithmic scale.) Page C has a higher PageRank than Page E, even though there are fewer links to C; the one link to C comes from an important page and hence is of high value. If web surfers who start on a random page have an 85% likelihood of choosing a random link from the page they are currently visiting, and a 15% likelihood of jumping to a page chosen at random from the entire web, they will reach Page E 8.1% of the time. PageRank (PR) is an algorithm used by Google Search to rank websites in their search engine results. PageRank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is. It is not the only algorithm used by Google to order search engine results, but it is the first algorithm that was used by the company, and it is the best-known.[3][4] Description[edit] Cartoon illustrating the basic principle of PageRank. where , and

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 jcpenney.com 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. Penney web site. 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”. Paid Links

The Advanced Google Searches Every Student Should Know - November Learning “Did he seriously just ask that? How old is this guy?” Well yes, I recently seriously just asked a group of students if they knew how to search Google. “Of course I know how to use Google,” I have been told by every student to whom I have asked the question. “Really? The truth is that every student can use Google on some level. If you watch your students use Google you will probably observe that most begin their search by simply typing the title of the assignment verbatim into Google (i.e., Iranian Hostage Crisis). After their results pop up, most students will look only at the first screen of results, believing that those top hits contain everything they will need to complete their assignment. But what happens when a meaningful search requires more thinking than simply typing in the assignment? Expert Google search strategies The internet presents our students with the significant challenge of learning how to access and synthesize massive amounts of information from all over the world.

Painting by Numbers Data Visualisation may be a hot topic right now but a new poster show at London's Transport Museum reminds us that getting complex information over in attractive ways is not a new challenge for the art director or designer Figures for 1923, by Charles Shepard, 1924 Painting by numbers - making sense of statistics will feature 20 London Underground posters, many dating back to the 1930s or earlier. The posters were designed not only to promote the benefits of travelling by London Transport but also in order to wow the travelling public with details of the remarkable service they were (hopefully) enjoying every day. Here, Speed, by Alfred Leete from 1915 reminds passengers of the dizzying speeds possible on the Tube, compared to alternatives of the time. And What It Takes to Move the Passengers - Problems of the Underground, by Irene Fawkes, reminds passengers of the resources needed to make their journey. If you only read CR online, you're mising out.

Comment le web de données change-t-il la nature de la toile ? En rendant les contenus du web lisibles par les machines, le web sémantique bouleverse notre univers informationnel et ouvre de nouvelles opportunités propres à redéfinir la nature du Web : d’un web de document à un web de données. (ce billet est issue d’une note de synthèse, réalisée dans le cadre de mes activités universitaires. Il s’agit d’un bilan de lecture autour du web de données. Il m’a semblé intéressant de le republier ici pour solliciter l’avis des connaisseurs de ce sujet, et ouvrir le débat) 1. A peine avons-nous commencé à explorer les nouveaux modèles d’affaires du Web 2.0 que déjà se profile un nouveau paradigme prometteur : le web de données. Les applications du Web 2.0 reposent de plus en plus sur la gestion, l’analyse et l’exploitation des massives quantités de données issues des UGC. Nos historiques de navigation sont enregistrés, tous comme nos requêtes sur des applications tierces, et l’immense champ des flux de données plus ou moins bien structurés. 2. 3. 4. 5. 6.

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. Now that is all well and good but from my point of view I want to know a few key points; 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?
