Client Side Code Versus Server Side Code

While there has been a continuous debate if client side scripting is better than server side scripting, we believe that a mix of both is best for any web application or portal. Here we have outlined some of the pros and cons of both.

Client Side Code

The client side code is inserted in the web page itself and is executed on the user’s internet browser. The scripting languages that can be used to write client side code include JavaScript, HTML and CSS. However, for your web application to be displayed properly, the browser must support these languages.

Advantages of client side code:

  • Allows for more interactive and quick loading websites
  • Immediate execution of client’s requests as they do not require to contact the server
  • May enhance the usability of websites for browsers that support the code

Disadvantages of client side code:

  • Every browser does not support scripts. Hence, some users might face difficulty if substitutes such as HTML have not been provided
  • Requires more time and effort to be developed
  • Every version of different browsers supports the script differently. Therefore, more testing is required.

Server Side Code

In a server side code, the website script is processed on the server before being downloaded by the internet browser. In this way, the requested web page or application is displayed as a regular HTML page while it is being loaded. The scripting languages for server side code are PHP, ASP.NET, Perl, Python, Java Server Pages etc.

Advantages of server side code:

  • Reduces load on the user’s computer
  • The site can be configured to use a content management system to simplify publishing, editing etc.
  • Website load times are generally reduced

Disadvantages of server side code:

  • Server side scripting does not offer as seamless experience for users as client side scripting does.
  • Scripting software must be installed on the server

As each of them has their own usability, most websites use a combination of both client side and server side code. The former one is good for sites that require attractive appearance and user interaction. The latter one can be used for those that require posting dynamic data.

Benefits Of A/B Testing

A/B testing, also called as split testing, is a process of experimenting between two or more variants of the same web page to determine which of them achieves more conversion rate. It involves validating that any changes made in the design or layout of your website is yielding better performance before you make changes in the site code. A/B testing allows you to assess different elements of your website including:

  • Placement, design and color of the buttons
  • The location, text or color of call-to-action
  • Product pricing
  • Headlines and product descriptions
  • Product placement and photos
  • Appearance and layout of website
  • Length of text on each page

Benefits of using A/B testing for your website:

  • Measure Performance Differences: A/B testing allows you to have an accurate measure of your website’s performance between two different alternatives. You just need to collect the recorded data to compare the results.
  • Measure Actual Behavior: While you are creating a website, it might be difficult to judge how a certain design or navigation would perform. By using A/B testing, you can get it evaluated by the real customers and have a better idea about the preferences of your target market. This will help you offer desirable products and services to your clients.
  • Increase Conversion Rate: A/B testing enables you to boost conversion rates on your landing pages as well as increase your current leads with the help of proven techniques and methods.
  • Improve Content: A/B testing helps you in initiating a successful content marketing campaign. It lets you know what type of data is given positive feedback by the users. Thus, you can make the required changes in your existing content adequately optimized for the target customers.
  • Lower Risks: A/B testing considerably reduces the risk involved in major decisions like marketing strategy and pricing. Analyzing consumer behavior before implementing anything increases the chances of success. With A/B testing, companies can appropriately invest their resources to yield maximum results and greater ROI. 
  • Easy To Design: The A/B test does not need to be carefully or technical designed to achieve accurate results. All you need to do is to decide the number of versions you want to test and split your website’s traffic among them.

Regardless of which things are you evaluating in your website, A/B testing is a simple and cost-effective way to know precisely which option will work the best for you.
