    In computing, a web widget is a software widget for the web. It''s a small application with limited functionality that can be installed and executed within a web page by an end user. A widget has the role of a transient or auxiliary application, meaning that it just occupies a portion of a webpage and does something useful with information fetched from other websites and displayed in place. Other terms used to describe web widgets include: portlet, web part, gadget, badge, module, snippet and flake. Widgets are typically created in DHTML or Adobe Flash.

    Widgets often take the form of on-screen devices such as clocks, event countdowns, auction-tickers, stock market tickers, flight arrival information, daily weather etc..

    Widget

    A widget is a stand-alone application that can be embedded into third party sites by any user on a page where they have rights of authorship, e.g. a webpage, blog, or profile on a social media site. Widgets allow users to turn personal content into dynamic web apps that can be shared on websites where the code can be installed. For example, a "Weather Report Widget" could report today''s weather by accessing data from the Weather Channel, it could even be sponsored by the Weather Channel. For website visitors to view, it must be embedded in a webpage, such as a Blogger blog sidebar. Even the portion of a blog where the ads are displayed is a widget.

    Widgets were also added to the Windows Operating System. They first appeared in Windows Vista. The default widgets include clock, CPU meter, picture puzzle and image slideshow. In 2012 Microsoft advised widget users to disable these from their PCs out of security concerns.

    Web developers have used third party code chunks in pages. Early web widgets provided functions such as link counters and advertising banners.

    Widgets may be considered as downloadable applications which look and act like traditional apps but are implemented using web technologies including JavaScript, Flash, HTML and CSS. Widgets use and depend on web APIs exposed either by the browser or by a widget engine such as Akamai, Clearspring, KickApps, MassPublisher, NewsGator, Widgetbox or many others.

    Sites such as MassPublisher, FormLoop and Widgetbox allow users to easily create widgets from their own content with no coding knowledge necessary.

    Major widget types

    Widgets come in many shapes and sizes, but two of the major types today are Web widgets and Desktop widgets. Web widgets are intended for use on (embedding in) webpages and have major implications in areas such as site performance, SEO and even backlink campaigns. Desktop widgets are embedded on local computers, and do not impact SEO or webpage performance.

    As an example, Widgetbox generate Web widgets that can be used on almost any website but not on pages using SSL (URLs beginning with https). Apple Desktop widgets can only be added to the desktop of your local (Apple) computer.

    Usage in social media

    End users primarily use widgets to enhance their personal web experiences, or the web experiences of visitors to their personal sites.

    The use of widgets has proven increasingly popular, where users of social media are able to add stand-alone applications to blogs, profiles and community pages. Widgets add utility in the same way that an iPhone application does. The developers of these widgets are often offering them as a form of sponsored content, which can pay for the cost of the development when the widgets'' utility maps to the user''s needs in a way where both parties gain. For example, a sports news brand might gain awareness and increased audience share in exchange for the utility of current game scores being instantly and dynamically available - the blog which posted the Sports score widget might gain in having a stickier site.

    Element of control

    One important factor with Widgets is that the host does not control the content. The content or the functionality it provides cannot be modified by the host. The content is pre-published by the publisher/author/service provider and the host can either accept that content or not use the widget. The host does, however, control the placement of the Widget. Because the host can always take the Widget down, it assures a large degree of mutual advantage and satisfaction with performance and content.

    Security considerations

    As any program code, widgets can be used for malicious purposes. One example is the Facebook “Secret Crush” widget, reported in early 2008 by Fortinet as luring users to install Zango adware.

    SEO Considerations

    One major consideration in the use of web widgets is how they''ll impact website SEO (Search Engine Optimization). Client-side widgets include pretty much anything rendered in JavaScript or Flash, and are by far the most common types of widgets you''ll see today. The content of these widgets is not visible to search engines, and will therefore not be seen as part of the content of a website. Server-side widget content is visible to search engines, but these are slightly harder to embed. In both cases, search bots can see the embed code for the widget itself, so some of the SEO concern can be alleviated this way—but website SEO should be considered whenever using a widget.
