Mobile SEO Overview | Mobile Friendly Websites | Google Developers Let's make sure your site shows up in search results. Here you can learn how to configure your site for multiple devices and help search engines understand your site. 3 ways to implement your mobile website There are three main techniques for implementing a website that can handle view screens of all types and sizes. Responsive web design: Serves the same HTML code on the same URL regardless of the users’ device (desktop, tablet, mobile, non-visual browser), but can render the display differently (i.e., “respond”) based on the screen size. Google does not favor any particular URL format as long as the page(s) and all page assets are accessible to all Googlebot user-agents. For more information on selecting a mobile site configuration (and weighing the pros and cons of each option), please see “Building Websites for the Multi-Screen Consumer”. The key points for going mobile As we discuss later, there are different configurations you can choose to make your site mobile-friendly.
Google desktop VS Google mobile : plusieurs algorithmes pour un seul index ! Le français Mickaël Marie, responsable SEO chez WAM-référencement, a posé une question à Gary Illyes et John Mueller au sujet de la Google Search Console.Son objectif était de savoir si Google différencierait l'index mobile de l'index desktop dans le suivi de l'état de l'indexation. Il est vrai que la question pourrait se poser pour les personnes qui voudraient mieux analyser l'indexation de leurs pages web, mais la réponse de Gary Illyes était plutôt attendue... Si John Mueller est resté muet sur le coup, Gary Illyes a répondu au référenceur lyonnais de la plus simple des manières, sur le réseau social de Larry Bird. En français dans le texte, sa réponse est sans équivoque : Non, cela n'aurait pas beaucoup de sens actuellement puisque nous n'avons qu'un "index desktop". En effet, si nous savons avec certitude que Google utilise des algorithmes spécifiques pour Google mobile, il est assez logique qu'un seul et même index serve de base au moteur de recherche.
Mobile Site Configuration & The Vary HTTP Header Yesterday, Google announced more changes to the Google mobile search algorithm , which we can expect to roll out shortly. This update is intended to improve the search experience for mobile users by “address[ing] sites that are misconfigured for smartphone users” — presumably by improving mobile rankings for sites that have been optimized according to their Mobile Optimization Guidelines . In an attempt to prevent some confusion, Google also updated these guidelines to include a list of common mistakes , along with ways to avoid said mistakes. In November 2011, when Google launched the GoMo project to help businesses make “m.” versions of their desktop sites, it seemed like a tacit endorsement for the development of mobile-specific pages from Google, and that was great. The inconsistency in Google’s messaging about mobile SEO leaves large, enterprise-level strategists wondering if it is truly possible to future-proof their mobile search strategy.

Vary with Care - IEInternals About the Vary Response Header As described in the HTTP/1.1 specification (RFC2616), the Vary response header allows a cache to determine if a cached (still fresh) response may be returned for a subsequent request, based on whether or not the new request's headers match those that were sent when the the previously response was originally cached. The Vary field value indicates the set of request-header fields that fully determines, while the response is fresh, whether a cache is permitted to use the response to reply to a subsequent request without revalidation. For uncacheable or stale responses, the Vary field value advises the user agent about the criteria that were used to select the representation. The Problem(s) Unfortunately, the WinINET caching engine (below Internet Explorer and other applications) does not cache outbound request headers. Note: IE's isn't the only cache with issues around Vary; see Internet Explorer 6
What will Google’s Accelerated Mobile Pages (AMP) mean for marketers? Google’s Accelerated Mobile Pages (AMP) project has launched, taking a huge stride towards Google’s stated goal of a “better, faster mobile internet.” But just what does AMP consist of, and what will it mean for the marketing industry? Last October, Google announced the introduction of its Accelerated Mobile Pages project, a new open-source initiative aiming to “dramatically improve the performance of the mobile web.” This latest move towards a more mobile-friendly web is Google’s answer to Facebook’s Instant Articles and Apple News. In the months since the announcement, we’ve seen a lot more information released about what AMP will consist of, its key features and how it will alter the experience of the mobile web. What is AMP, and what does it do? Simply put, Accelerated Mobile Pages is a stripped-down version of the mobile web which runs on a reinvented version of the language used to create web pages: HTML. Sounds good so far. But don’t despair just yet. Fine-tuning ad control

Google's Starting To Enforce Smartphone Penalties: The Evidence In June, Google announced it would be adjusting search rankings appearing on smartphones based on how well the site in question handled the mobile user experience. The company didn’t say exactly when these changes would be rolling out, but only said it planned “to roll out several ranking changes in the near future that address sites that are misconfigured for smartphone users.” These smartphone misconfiguration errors include faulty redirects like app interstitials or homepage redirects, and smartphone-only errors such as unplayable videos, smartphone-only 404 pages and serving 404 pages or redirects when equivalent content exists on the desktop site. It’s anyone’s guess how far away “the near future” is; so at SMX East, I presented results of a random sample of about a hundred queries where sites that exhibited these smartphone misconfiguration errors showed up in smartphone and desktop search results.

amphtml/examples/metadata-examples at master · ampproject/amphtml Etude SEO : les particularités des sites bien positionnés par Google sur mobile L'éditeur Searchmetrics a analysé et comparé les résultats qui se hissent au sommet des résultats de Google sur mobile et sur desktop. Certaines observations sont intéressantes. Fournisseur d'outils dédiés au SEO, Searchmetrics est aussi bien connu pour ses études. Sa dernière en date s'est intéressée aux particularités des sites les mieux classés par Google sur mobile. Pour cela, sa méthodologie a été d'observer en détail les caractéristiques des 30 premières pages qui remontaient sur 10 000 requêtes effectuées sur un terminal mobile. Avertissement préliminaire, comme souvent avec les études de Searchmetrics, il faut bien veiller à ne pas confondre corrélation et causalité. 1- Les pages les mieux positionnées sur mobile ne sont pas les plus légères L'étude de Searchmetrics montre bien (voir ci-dessous) que le poids moyen des pages sur les 10 premiers résultats remontés par Google sur mobile est inférieur à celui observé sur les 10 premiers résultats sur desktop.
