To create these versions, companies often have to eliminate many of the features and capabilities of the desktop versions.<\/p>\n<p style=\"text-align: justify;\">When a user accesses a website, the website determines the kind of device that&#8217;s being used and serves a different set of Web pages to a mobile device user than to a desktop user.<\/p>\n<p style=\"text-align: justify;\">Imaginez que vous effectuez une recherche Google sur votre mobile <a href=\"https:\/\/seo.london\/fr\/contenu-de-what-is-cornerstone-35\/\">t\u00e9l\u00e9phone<\/a> et de voir des r\u00e9sultats de recherche qui sont exactement <a href=\"https:\/\/seo.london\/fr\/link-building-how-what-do-dons\/\">ce que<\/a> you are looking for.

La conception serait cibl\u00e9e sur les appareils mobiles, puis adapt\u00e9e \u00e0 d'autres plateformes telles que les ordinateurs de bureau. Un design d'indexation mobile-first est g\u00e9n\u00e9ralement simple et concis et utilise des formes g\u00e9om\u00e9triques, des couleurs vives, une typographie forte et des espaces blancs comme \u00e9l\u00e9ments de design.<\/p>\n<p style=\"text-align: justify;\">La conception place les \u00e9l\u00e9ments d'appel \u00e0 l'action au premier plan et int\u00e8gre des m\u00e9thodes de communication modernes telles que le chat et les chatbots. Il va sans dire qu'un site index\u00e9 par Google mobile-first se charge rapidement, et qu'il est constamment mesur\u00e9 pour maintenir ou am\u00e9liorer sa vitesse.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"2-adapt-your-website\"><\/span>2. Adaptez votre site Web<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">If you&#8217;re not ready for a full mobile-first indexed redesign of your website, you can adapt what you currently have to be mobile-friendly. Since you&#8217;re still taking a desktop version and adapting it for mobile devices instead of the other way around, it&#8217;s not technically a Google mobile-first strategy. But it is a practical step on the way to a mobile-first indexed website design that enables you to appear as mobile-first to search engines.<\/p>\n<p style=\"text-align: justify;\">Lorsque vous adaptez votre site web actuel \u00e0 cet environnement Google mobile-first, l'objectif est g\u00e9n\u00e9ralement de fournir le m\u00eame contenu \u00e0 tous les utilisateurs, quel que soit l'appareil qu'ils utilisent.<\/p>\n<p style=\"text-align: justify;\">However, the way that content is formatted and presented is different depending on the size of the screen that&#8217;s being used to view it. It&#8217;s still acceptable in this transition to include some additional functionality, such as menu options or buttons, that appear only when the website is accessed by a computer. Even Google does this.<\/p>\n<p style=\"text-align: justify;\">Heureusement, il existe des outils qui permettent de faciliter cette transition vers un site adapt\u00e9 aux mobiles. Et il existe des outils qui vous permettent de mesurer votre succ\u00e8s et d'identifier les domaines qui doivent encore \u00eatre am\u00e9lior\u00e9s.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"3-responsive-websites-and-mobile-first-indexing\"><\/span>3. Sites web r\u00e9actifs et indexation en priorit\u00e9 des mobiles<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">To make this transition to a more mobile-friendly or Google mobile-first website, the word you need to embrace is responsive. Responsive Web design is an approach that automatically adapts the presentation of a website according to the user&#8217;s platform, orientation and screen or window size.<\/p>\n<p style=\"text-align: justify;\">Imagine a website that&#8217;s open on your desktop computer and visible on your computer monitor. When you click on the corner of the window and <a href=\"https:\/\/seo.london\/fr\/divi-est-il-mauvais-pour-le-referencement\/\">draguer<\/a> it to make the window smaller, what happens? On a website that&#8217;s not responsive, nothing happens. You simply cut off everything that used to be in view and now you have to scroll left and right to see that content.<\/p>\n<p style=\"text-align: justify;\">On a responsive website, however, the website will automatically reformat itself once your viewing window reaches certain sizes so that all content remains visible in that window. Rather than having content appear side-by-side, it&#8217;s stacked vertically. While you might have to scroll down the page to view all the content, the content you see fits within your viewing window and you don&#8217;t have to scroll left and right to see it.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"4-content-management-systems-eg-wordpress\"><\/span>4. Syst\u00e8mes de gestion de contenu (par exemple, WordPress)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Si vous utilisez un contenu <a href=\"https:\/\/seo.london\/fr\/services-de-gestion-du-referencement\/\">gestion<\/a> syst\u00e8me (<a href=\"https:\/\/seo.london\/fr\/comment-faire-du-seo-onpage-dans-wordpress\/\">CMS<\/a>) tels que <a href=\"https:\/\/seo.london\/fr\/les-sites-wordpress-sont-ils-bons-pour-le-referencement\/\">WordPress<\/a>, you should be using a responsive theme. If your current theme is not responsive and there&#8217;s a newer, responsive version available, upgrade to that version. If no responsive version exists, switch to a responsive theme.<\/p>\n<p style=\"text-align: justify;\">Le th\u00e8me se chargera de la plupart des t\u00e2ches difficiles pour vous. Vous devrez <a href=\"https:\/\/seo.london\/fr\/revue-de-presse-sur-le-referencement-local\/\">revue<\/a> how the responsive pages look on different mobile devices and determine if you need to change the way you present some information that doesn&#8217;t convert well to responsive pages.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"5-web-development-toolkits-eg-bootstrap\"><\/span>5.

You&#8217;ll get a <a href=\"https:\/\/seo.london\/fr\/rapport-sur-les-resultats-de-la-recherche-en-ligne\/\">rapport<\/a> qui vous indique dans quelle mesure votre site web est adapt\u00e9 aux mobiles, avec des suggestions sp\u00e9cifiques sur la mani\u00e8re d'am\u00e9liorer votre site web. <a href=\"https:\/\/seo.london\/fr\/comment-trouver-votre-score-dautorite-de-domaine\/\">score<\/a>.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"7-fast-loading-websites\"><\/span>7. Sites web \u00e0 chargement rapide<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Whether you have a desktop site, mobile-friendly website or mobile-first website, the assumption today is that your website will load quickly. While a discussion of all the factors that influence how quickly your website loads is beyond the scope of this article, there are a few design elements that can significantly slow down your website&#8217;s loading that you should be aware of.<\/p>\n<p style=\"text-align: justify;\">Heureusement, la plupart des th\u00e8mes et des kits d'outils r\u00e9actifs comprennent des fonctionnalit\u00e9s qui permettent, au moins partiellement, de <a href=\"https:\/\/seo.london\/fr\/seo-local-sans-adresse-physique\/\">adresse<\/a> certains de ces domaines pour aider votre site Web \u00e0 se charger plus rapidement sur un appareil mobile.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"8-how-a-website-is-processed\"><\/span>8. Comment un site web est trait\u00e9<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">When you visit a website, it loads the code for the page that you&#8217;re viewing into the memory on your mobile device, and then processes the code to <a href=\"https:\/\/seo.london\/fr\/format-et-structure-de-larticle\/\">format<\/a> et affiche la page sur votre appareil. Lorsque vous cliquez sur un lien pour passer \u00e0 la page suivante, la page sur laquelle vous vous trouviez est supprim\u00e9e et la page suivante est charg\u00e9e en m\u00e9moire. Plus il y a de pages \u00e0 charger, plus il faut de temps pour les r\u00e9cup\u00e9rer, les envoyer sur l'internet et les charger sur votre appareil.<\/p>\n<p style=\"text-align: justify;\">Plus il doit traiter de code, plus il lui faut de temps pour formater et pr\u00e9senter ce qu'il a charg\u00e9 sur votre \u00e9cran. En d'autres termes, si vous chargez et traitez moins de code, votre site Web se chargera g\u00e9n\u00e9ralement plus rapidement.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"9-images-and-google-mobile-first-indexing\"><\/span>9. Images et indexation Google Mobile First<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Les fichiers d'images ou de photos sont souvent la cause de la lenteur de chargement d'un site Web. Plus la r\u00e9solution de l'image est \u00e9lev\u00e9e, plus le fichier est volumineux et plus il met de temps \u00e0 se charger. Soyez r\u00e9aliste quant \u00e0 la r\u00e9solution dont vous avez besoin pour le <a href=\"https:\/\/seo.london\/fr\/google-nindexe-pas-les-images\/\">images<\/a> vous affichez et r\u00e9duisez les images pour qu'elles se chargent plus rapidement.<\/p>\n<p style=\"text-align: justify;\">Selon le format que vous utilisez, vous pouvez r\u00e9duire la taille des images en sacrifiant ou non leur qualit\u00e9. Celles qui sacrifient un peu de qualit\u00e9 sont g\u00e9n\u00e9ralement beaucoup plus petites que celles qui conservent le m\u00eame niveau de qualit\u00e9.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"10-code-and-google-mobile-first-indexing\"><\/span>10. Le code et le Google Mobile First Indexing<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Votre navigateur commence \u00e0 formater la page Web au fur et \u00e0 mesure que les donn\u00e9es sont charg\u00e9es. Toutefois, certains codes obligent le navigateur \u00e0 arr\u00eater le formatage et \u00e0 attendre d'autres codes ou m\u00eame le chargement de la page enti\u00e8re avant de reprendre sa t\u00e2che de formatage.<\/p>\n<p style=\"text-align: justify;\">This is called blocking. To the extent you can, you want to reduce the size of the code that&#8217;s loaded and eliminate any blocking code. One way to reduce code size is to minify it by removing comments and excess white space.<\/p>\n<p style=\"text-align: justify;\">These are important for programmers to understand the code, but they aren&#8217;t necessary for a browser to process it. If you can&#8217;t minify code, some Web servers will send a compressed version of the code to your browser, which will load the smaller version and then decompress it.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"11-background-loading-and-google-mobile-first-indexing\"><\/span>11. Chargement en arri\u00e8re-plan et indexation Google Mobile First<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">When you&#8217;re viewing a Web page, you only see the portion of the page that&#8217;s within your viewing window. If your browser loads and formats what you see in your window first, it can continue to load and format other data in the background until the page is complete.<\/p>\n<p style=\"text-align: justify;\">To you, the Web page appears to load quickly and you don&#8217;t necessarily realize that it&#8217;s continuing to load and format content unless you have to wait a <a href=\"https:\/\/seo.london\/fr\/base-de-connaissances\/seo-combien-de-temps\/\">longue p\u00e9riode<\/a> lorsque vous essayez de faire d\u00e9filer la page vers le bas.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"12-speed-measurement-and-improvement-tools\"><\/span>12. Outils de mesure et d'am\u00e9lioration de la vitesse<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">A page on the Google Developers site called Make the Web Faster provides tips, best-practices advice and resources to help you make your website load more quickly. A primary tool in that toolkit is called PageSpeed Insights. PageSpeed Insights shows you what happens from the time you start loading your website to the time it&#8217;s been loaded, formatted and presented on a mobile or desktop device.<\/p>\n<p style=\"text-align: justify;\">This enables you to see what&#8217;s causing your website to load more slowly so you know what to change. The tool often provides you with specific suggestions for how to improve <a href=\"https:\/\/seo.london\/fr\/base-de-connaissances\/comment-surveiller-les-performances-du-referencement\/\">performance<\/a> et vous fournit m\u00eame des versions optimis\u00e9es de vos fichiers images qui se chargeront plus rapidement.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"13-adapt-to-survive\"><\/span>13. S'adapter pour survivre<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Even if you can&#8217;t do a truly Google mobile-first design right now, you can make your website appear to be mobile-first by using responsive Web pages and reducing the time it takes to load and display your site. These two strategies might not result in higher search engine rankings because they are mandatory, but they should help you avoid being penalized for not having adopted a mobile-first approach.<\/p>","protected":false},"excerpt":{"rendered":"<p>Google a annonc\u00e9 une strat\u00e9gie d'indexation mobile-first en mars 2018.
