Code optimization helps a website to load faster and also aims at removing the problem elements from the code like white spaces and comments which prevents bots or crawlers from finding and indexing the page.

Improving internet technologies keep on providing us with attractive and multifunctional websites. These websites are intended to enhance the user experience while browsing and to serve multiple functionalities. However, in order to attract more number of users, a website is desired to be attractive, understandable as well as engaging to the user. For a new user, there will be a need of an intermediate router to direct them to the website and this is where the role of a search engine comes in.

In order to attract more number of users to a website, it is advisable to attract search engine bots to that website so they can index the website and make it appear in search results. To do so, various search engine optimization strategies and techniques are performed, website code optimization being one of them.

With website code optimization, a spider is attracted to the website so that it can index it in search result. Such optimization is achieved by formatting the code of the website in such a way that unnecessary elements are removed. However, such formatting shouldn't affect the functionality of the site as we want to cater to the audience visiting the website and not only to the search engine bots. Few things which should be considered in order to optimize the code of a website are:

Placing the style-sheets at higher locations in the header provides efficient web solution in terms of SEO, for web sites. It means placement of the style-sheets should be kept just after the < title > or < meta >. This helps a web-crawler to easily differentiate between the text and style-sheet area.
Using < script > at the bottom of the page, next to the closing of < body > is quite a good practice to deploy in the code of a website. Although it is not always feasible to use this technique, the deployment of such methods wherever possible, speeds up the loading of website.
While making an AJAX call, if an option exists to choose between $_GET and $_POST, then choose $_GET as it sends out only one TCP packet on the network according to a study conducted by the team of YahooMail.
Make use of content delivery network or CDN for efficient flow of content from the server to the client or end user. CDN is basically a set of distributed servers selected for delivering the content to the user. The selection of the server is based on the location proximity of the user. Considering Google's CDN is a better known practice to improve the response time of a website.
Making use of redirects hinders the user experience and delays the response of the page as nothing can be downloaded until the HTML document has arrived to the user. So in order to load a website faster, it is desired not to use redirects as nothing on the page can be rendered.

Some other practices which help developers or designers to optimize a website is making use of Console.log() to debug a website. This technique, along with the FireBug, a developers extension of Mozilla Firefox, lets the developer or designer to debug the website in case any value has been entered wrong or such closely related events.
