Pitfalls to Avoid as Jscript and CSS is Indexed by Google

Each business optimizes its website to get more visitors through popular online search engines like Google, Bing and Yahoo. Many entrepreneurs even deploy developers to frequently optimize the look, feel and performance of their websites to deliver richer user experience. Most developers use JavaScript and CSS heavily to make the websites more dynamic and engaging. Google recently announced that the search engine ranking of a website can be affected negatively by the JavaScript used in the web pages. Google announced that it has modified its page indexing and page rendering systems to meet the growing usage of JavaScript code and CSS style sheets.

According to GoogleWebMasterCentral.blogspot.com, “We have been gradually improving how we do this for some time. In the past few months, our indexing system has been rendering a substantial number of web pages more like an average user’s browser with JavaScript turned on. Sometimes things don’t go perfectly during rendering, which may negatively impact search results for your site.” However, Google warned website developers about a number of potential issues that must be addresses to get their JavaScript and CSS indexed smoothly.

Pitfalls to Avoid for Getting JavaScript and CSS Indexed by Google

Blocking JavaScript and CSS Files
Most developers use external CSS style sheets and JavaScript code to increase page loading speed. But the Google crawler cannot retrieve the code, if the JavaScript or CSS in separate files are blocked. Unlike a normal user, the Google indexing system cannot see the website properly. So the programmer must allow the Googlebot to index the content properly by retrieving the JavaScript and CSS. When the Googlebot can retrieve and index the external resources properly, it becomes easier the algorithms to decide if the web pages are optimized for mobile devices.

Capacity of the Web Server
The ability of the web server to handle higher volume of crawl requests will also have an impact on the website’s search engine ranking. When the server fails to handle a higher volume of crawl requests for resources, the Googlebot fails to render and index the pages properly. So the performance and capability of the web server must be optimized to make it effective in handling crawl requests for resources more efficiently.

Make JavaScript Optional
Despite being widely used for website and web application development, JavaScript is still not supported by several web browsers. The user experience is always affected negatively when a user access the website on web browsers that do not support JavaScript. So the developers must allow users to degrade their websites gracefully to access the content on browsers not compatible with JavaScript. The degradation of websites will further make the search engine crawler index the websites while ignoring the JavaScript code.

Avoid Complex JavaScript Code
Often developers try to optimize the performance of a website through complex JavaScript code. When the JavaScript code is too complex, it becomes difficult for Googlebot to execute the code. So the search engine crawler fails to render the web page in a complete and accurate way. The improper rendition of web pages further makes it tough for Googlebot to index the website. Likewise, developers also use JavaScript code to remove or hide content from a page. The feature makes the web pages more interactive and dynamic. But it prevents the Googlebot from indexing the web pages properly.

The website developers must remember that the search engine ranking of a website is also affected by its page loading speed. So they must organize the JavaScript and CSS code properly to optimize the website’s page loading speed. It is also a great idea to reduce page loading time by using external CSS style sheets and JavaScript code.

Tools and Languages for Improving the Process of Creating JavaScript Applications

As a powerful client-side scripting language, JavaScript is used widely by developers to optimize user experience. The browser based language is coded within the web pages, and the output displayed to users without putting any stress on server. However, developers have to invest additional time and effort to write advanced JavaScript programs by overcoming the issues related to difference in web browsers. That is why; web developers use a library of pre-written JavaScript to rapidly build JavaScript-based applications for AJAX, while overcoming the issues related to browser compatibility.

Some of the Widely Used JavaScript Frameworks

Javascript ajax web development

JQuery: It is one of the most popular JavaScript frameworks used by web developers across the world. JQuery is also used by some of the most reputable and largest companies like Microsoft, Google, IBM and Netflix. The library is designed with features to make it simpler for developers to use accomplish several common tasks without requiring additional code. They can simply wrap the tasks into methods, and call the method by writing a single line code. In addition to providing plug-ins for a wide variety of task, jQuery further allow users to manipulate HTML, CSS and DOM, create HTML event methods, and use AJAX.

Prototype: The open source JavaScript framework enables programmers to perform a variety of common task by using a single Application Programming Interface (API). The API comes with specific features and methods that can be used by programmers to manipulate DOM and AJAX. The library further enhances JavaScript by adding inheritance and classes.

MooTools: Like Prototype, MooTools also allows developers to use an Application Programming Interface (API) to write complex JavaScript programs within a short span of time. But the framework comes with a set of animation functions and lightweight effects. The library is further compatible with major web browsers including Firefox, Chrome, Internet Explorer, Opera and Safari.

Yahoo! User Interface (YUI): The open source library launched by Yahoo can be used by developers to develop interactive web applications by harnessing the power of JavaScript and CSS. Despite being modular and lightweight, YUI still comes with features required to build simple as well as complex JavaScript-based applications. It further supports six distinct types of components including YUI core, UI controls, utilities, CSS components, developer tools and build tools.

Backbone.js: The framework provides models that can be used by developers to give structure to the internet applications. The models come with custom and key-value binding events. The API provide by Backbone.js can also be connected with your existing API over RESTful JSON interface. At the same time, the API also supports several views, functions and event handling features.

Spine.js: The simple and lightweight JavaScript framework supports Model View Controller pattern. So developers can use the library to keep business rules separate from presentation. Unlike other JavaScript libraries, Spine does not come with loads of complex widgets. The developers can avail the feature to save the time required to configure and setup the widgets.

AngularJS: The framework is designed to overcome the limitation of HTML. As HTML cannot be used for developing dynamic web applications, developers use AngularJS to extend the HTML vocabulary to complement the needs of their project. AngularJS further provides a set of tools required to create customized framework for the application development. The framework can be further integrated with other libraries to save the developers’ time and effort.

Agility.js: Like Spine.js, Agility.js is also designed with support for Model View Controller pattern. The developers can use the framework to increase the maintainability and reusability of their code. Despite being a small JavaScript file, Agility does not require programmers to write the entire code in JavaScript. They have option to include HTML, JavaScript and CSS within JavaScript objects.

On the whole, a developer has option to choose from many tools, libraries and languages to improve the process of creating JavaScript applications. But it is also important to evaluate the features of each JavaScript framework according to the nature and needs of the application.
