It is accessed directly via the web browser and can be used on various devices and operating systems, such as Android and iOS, regardless of the platform. Installation via an app store is not absolutely necessary, as the user can add the PWA directly to the home screen of their device.<\/p>\n<h2>Properties and technical basis of PWAs<\/h2>\n<p>PWAs are characterized by specific features that significantly improve the user experience:<\/p>\n<ul>\n<li><strong>Reliability:<\/strong> Content loads even with a poor or no Internet connection, as it uses offline functionalities through so-called service workers. These <a href=\"https:\/\/csw.agency\/en\/glossar\/javascript\/\">JavaScript<\/a>-Scripts operate in the background and cache important data and assets.<\/li>\n<li><strong>Speed:<\/strong> PWAs respond quickly to user input, offer short <a href=\"https:\/\/csw.agency\/en\/warum-pagespeed-optimierung-nicht-alles-ist\/\">Loading times<\/a> and smooth interactions, similar to a native app. This is also achieved through service workers and optimized caching.<\/li>\n<li><strong>Commitment:<\/strong> They offer an appealing user experience that is similar to that of a native app. This includes functions such as push notifications, the option to install on the home screen (add-to-homescreen) and a full-screen mode without a browser interface.<\/li>\n<\/ul>\n<p>The technical basis of a PWA is based on common web technologies such as <a href=\"https:\/\/csw.agency\/en\/glossar\/html\/\">HTML<\/a>, <a href=\"https:\/\/csw.agency\/en\/glossar\/css\/\">CSS<\/a> and <a href=\"https:\/\/csw.agency\/en\/glossar\/javascript\/\">JavaScript<\/a>. Specific APIs and concepts are also used:<\/p>\n<ul>\n<li><strong>Service Workers:<\/strong> These background scripts enable offline caching, push notifications and the updating of content in the background.<\/li>\n<li><strong>Web App Manifesto:<\/strong> A JSON file that provides the browser with information about the web application, such as name, icon, start URL and display options that are relevant for the \u201einstallation\u201c on the start screen.<\/li>\n<li><strong>HTTPS:<\/strong> Secure data transmission via HTTPS is absolutely essential for PWAs, as it guarantees the confidentiality and integrity of the data and is a prerequisite for the use of service workers.<\/li>\n<li><strong><a href=\"https:\/\/csw.agency\/en\/mobile-first-2\/\">Responsive design<\/a>:<\/strong> PWAs are designed to automatically adapt to different screen sizes and devices to provide a consistent user experience.<\/li>\n<\/ul>\n<h2>Advantages for users and companies<\/h2>\n<p>Progressive web apps offer significant advantages for both end users and companies:<\/p>\n<ul>\n<li><strong>For users:<\/strong>\n<ul>\n<li><strong>No installation from the App Store:<\/strong> Direct access via a URL without the detour via app stores saves time and storage space on the device.<\/li>\n<li><strong>Platform independence:<\/strong> A PWA works on almost any end device and operating system, which ensures broad availability.<\/li>\n<li><strong>Offline capability:<\/strong> Important content is also accessible without an active Internet connection.<\/li>\n<li><strong>App-like experience:<\/strong> Fast <a href=\"https:\/\/csw.agency\/en\/warum-pagespeed-optimierung-nicht-alles-ist\/\">Loading times<\/a>, smooth navigation and push notifications improve the user experience.<\/li>\n<\/ul>\n<\/li>\n<li><strong>For companies and SEO:<\/strong>\n<ul>\n<li><strong>Increased visibility and <a href=\"https:\/\/csw.agency\/en\/glossar\/search-engine-optimization-seo\/\">SEO<\/a>-Advantages:<\/strong> PWAs are available via <a href=\"https:\/\/csw.agency\/en\/ki-search-engine-optimization\/\">Search engines<\/a> <a href=\"https:\/\/csw.agency\/en\/glossar\/ranking\/\">indexable<\/a>, which increases their reach compared to native apps. Google evaluates aspects such as <a href=\"https:\/\/csw.agency\/en\/warum-pagespeed-optimierung-nicht-alles-ist\/\">Fast loading times<\/a> and <a href=\"https:\/\/csw.agency\/en\/mobile-first-2\/\">Mobile friendliness<\/a> positive, which affects the <a href=\"https:\/\/csw.agency\/en\/glossar\/ranking\/\">Ranking<\/a> can have an effect.<\/li>\n<li><strong>Lower development costs:<\/strong> As a single code base is used for all platforms, there is no need for separate developments for iOS and Android, which reduces costs and maintenance work.<\/li>\n<li><strong>Improved user loyalty and <a href=\"https:\/\/csw.agency\/en\/conversion-rate-optimization\/\">Conversion rates<\/a>:<\/strong> The seamless, fast and reliable experience leads to higher dwell times, lower <a href=\"https:\/\/csw.agency\/en\/glossar\/bounce-rate-bounce-rate\/\">Bounce rates<\/a> and increased <a href=\"https:\/\/csw.agency\/en\/conversion-rate-optimization\/\">Conversions<\/a>.<\/li>\n<li><strong>Independence from app stores:<\/strong> Companies are not bound by the guidelines and commission models of app stores.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>By combining these advantages, Progressive Web Apps represent a forward-looking solution for an effective digital presence that meets both the requirements of modern users and the strategic goals of companies.<\/p>","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false,"_lmt_disableupdate":"no","_lmt_disable":"no","footnotes":"","_links_to":"","_links_to_target":""},"categories":[22],"class_list":["post-40494","glossar","type-glossar","status-publish","hentry","category-digital-services"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.2 (Yoast SEO v27.8) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Progressive Web Apps &#187; CSW.AGENCY<\/title>\n<meta name=\"description\" content=\"PWA: Moderne Webanwendung, die Website-Zug\u00e4nglichkeit &amp; native App-Funktionalit\u00e4t vereint.
