J

Javascript – A client-side scripting language that can be embedded into HTML [link:] documents to add dynamic features.

Search engines do not index most content in Javascript. In AJAX [link:], JavaScript has been combined with other technologies to make web pages even more interactive.

Jump Page – An entry into a site other than the homepage. It may be a legitimate landing page, used to measure the results of a specific promotion or campaign. However, these pages are often created exclusively to spam search engine results, or misrepresent a site’s content. Search engines frown heavily on the use of these doorway pages [link:], and may penalize sites if the practice is reported and/or discovered.

JQuery – JQuery is a lightweight cross-browser JavaScript library that emphasizes interaction between JavaScript [link:] and HTML [link:]. JQuery’s syntax is designed to make it easier to navigate a document, select DOM elements, create animations, handle events, and develop AJAX [link:] applications.

JQuery also provides capabilities for developers to create plugins on top of the JavaScript library. Providing this option, developers are able to create abstractions for low-level interaction and animation, advanced effects and high-level, theme-able widgets. This contributes to the creation of powerful and dynamic web pages.

Java applets

Small programs written in the Java programming language that can be embedded into web pages. Applet programs run on the Internet user’s computer rather than the web server’s computer. Search engines can not run Java applets. Consequently, if navigation or content is embedded in a Java applet, it will be invisible to the search engines and will not get indexed. Java source code gets compiled into executable code called “bytecode.”

JavaScripts

programs written in the JavaScript programming language. JavaScripts run on the Internet user’s computer rather than the web server’s computer. Search engines can not run JavaScripts. Consequently, if navigation or content is embedded in a JavaScript
