Today’s world is dominated by mobility and all smartphone users want sites to be loaded in the minimal time. No one wants to wait for loading data and images. In technology’s race, as a UI developer, I personally feel that some crucial points must be kept in mind before writing code. Web optimization plays a key role in web development.
What is Website Optimization? A technique used to describe the procedures to optimize the speed at which your website loads in a Web browser. This type of optimization generally involves editing your website to optimize scripts, HTML, or CSS code for faster loading. It also reduces the number of components, such as images, scripts, or videos that are required to render the webpage.
The key points for website optimization are as follows:
Minimize HTTP Requests: The speed of website optimization depends upon the volume of HTTP requests going to the server side.
Higher number of HTTP requests = Slower Website
Less number of HTTP Requests = Website will load faster
To minimize HTTP requests, follow the points below:
Use less images
Use CSS instead of images whenever possible
Merge multiple style sheets (CSS) into one CSS.
Optimized HTML Code: Always use optimized HTML code in programming. In order to achieve this, follow the points below:
Avoid table structures
Avoid unnecessary DIV elements
For repetitive structures use UL and LI
Optimized CSS: It is the backbone of websites. For optimized CSS code, follow the points below:
An image sprite is a combination of multiple images put into a single image. A web page with lots of images takes longer to load and generates multiple server requests (HTTP Requests). Using image sprites will reduce the number of server requests and save bandwidth. We can combine many images into one and use it by calling its background position. Like (background: url('img_navsprites.gif') -47px 0;)
Use of image smasher
Always use an image smasher tool to compress the size of images. These tools compress images to almost half their original size, without affecting their quality.
SEO Semantic Code
In a website, content is king. Always use fresh content and avoid duplication. The HTML5 specification is developed especially for creating well-optimized sites; it helps make indexing fast and reliable. These HTML5 SEO tags are also used by search bots while crawling and indexing. For example, the search crawler will first check the information in <article> tag as most important and will name it with the title from <header> block. It will then go to the next pages from <nav> block.
W3C validated Code
W3C stands for the World Wide Web Consortium, which is the recognized standards organization for the World Wide Web. These standards are used to help guide web developers and browsers in developing code that lives up to certain universal standards. In a nutshell, they write the rule-book that helps define our code and whether it is well or poorly written.
