Apply these tried and tested tips to optimize your website! Optimization is for everyone!

Digital era exposed Canadian market to the millions of websites. Most of these are unfortunately bothersome and clunky due to poor optimization. There are a number of issues you may encounter in such websites such as the browser incompatibilities, non-mobile ready, slow loading time and much more.

This article will go over performance test tips you can use to optimize the performance of your website. You can dramatically enhance the overall speed and performance with the following tips.


Clean-up your HTML Document

Almost all website’s backbone is based on HTML that allows you formatting with text organizing features (lists, heading, sub-heading, etc.), as well as you have the options for creating attractive graphics. You can update the content of your website in search engines timely as web crawlers can easily read HTML. It is recommended to write the HTML code in concise manner for effectiveness. There are some practices that are beneficial if you need to reference other resources in HTML.

You should create proper CSS stylesheets after creating the website’s HLML skeleton. To ensure rendering is progressive it is preferable to put your CSS components within the header of the HTML document, rather than placing it near the bottom. Such a strategy allows your visitors to wait on black screen, although does not improve the website’s speed. It is a way to optimize your front end as visitors may not find it bothersome if the visual content of your website is already loaded. It is consistent with the perceived performance.

You must never put your JavaScript attributes in place of CSS and HTML components in the header because it will block the processing of these elements. Such a blunder may let your visitor keep waiting on the blank page and eventually leave impatiently. JavaScript attributes must be placed at the bottom of your page to avoid this issue.

Preferably use async script to load in JavaScript. It will prevent processing of HTML rendering from blocking due to script tags if it crosses it even in the mid-document. Mostly, HTML is integrated with JavaScript and CSS attributes as commonly used tools for web designing it tends to slow down the webpages. However, they can help you transform your pages if you use them in appropriate manner with special care. Best practices in using JavaScript and CSS attributes include avoiding to embed code. It is because it will lead to increase the load time for webpages when you refresh it as JavaScript are used in script and CSS in style tags.

Don’t bother about combining files in CSS script as you most likely used to do for referencing a file in your HTML code. This practice is no more used now after HTTP/2 as you can implement multiplexing for HTTP responses and requests using connection from single TCP. Thus, you do not need to combine scripts tediously in one file.

Optimize CSS Performance

You can achieve a professional and clean content with cascading style sheets. Except for inline CSS you need HTTP requests, so you will need to reduce bloated files without removing the important features. The browser will need to load several files at a time when all of the layout links, plugins, and banners are placed in different files. It can take longer to load the CSS files from external sources that is not a major problem now.

There is an outdated method used to prevent the parallel downloading in the browsers; @import directive. The best practice promote link tag as it extents the websites performance on front end. Another advantage of using link tag is when external style sheets are requested they do not prevent downloading parallel within the browser.


Minimize Request for External HTTP

Although, mostly HTTP requests are present in a large website portion in loading time, however, external resource loads and its speed depends on the location, server infrastructure and other attributes of the host provider. You will need a minimalist outlook to review your website as a foremost objective to reduce requests for external HTTP.

Enhance your visitors’ experience by adding exciting components to your webpage and eliminating incompetent features such an excessive CSS, unnecessary Javascript, unnecessary plugins, and unnecessary images. Now that you have removed all the irrelevant content trim down the weight of the remaining. To manage HTTP requests best practices include prefetching, CDN services, and compression tools.


To remove the unnecessary characters you can use a technique to minify CSS, JS and HTML# within a file. You may use notes and indentations if you write code in editor. Although, it adds extra bytes, it also makes your code readable. Minification tool can be integrated easily via CSS, JS, and HTML files to trim down the bytes.


There is a technique used to enhance the user experience, prefetching. It fetches the necessary data and resources before the need arises for the visitor. There are pre-rendering, DNS, and link prefetching techniques. It gathers the JavaScript, CSS images, and URL well before you leave the page. It require minimum time to load pages making navigation though links smooth for the visitors. It depends on the type of technique you use, however it is easy to enable prefetching. You can add tag in your HTML code to link attributes.


Content delivery method and caching can be integrated for your website’s performance and speed to improve. In using Content delivery network (CDN) you are linked with the network server globally. If you have global visitors this can be obviously important for you. Using this technique may help your visitors in data loading from nearby servers. Using CDN you can rapidly compress your files across the globe automatically.

A network diagram for content delivery may help you reduce the delivery time, although there are other techniques such as leveraging the browser caching. For fast delivery of files your browser can use its own cache if you set up the browser properly. You can directly perform this configuration method from the server of origin in your configuration file.


Gzip and Brotli for Compression Files

In place of CDN you can use other methods of file compression for optimization of your front end on origin server. Mostly, you are likely to use such a technique for easy management and lightweight content. Gzip is recognized to be the most used methods of file compression. It is very effective to shrink PNG images, audio files, documents, etc.

Brotli is a new but a popular compression algorithm, which is updated by various organizations including Google, regularly. It’s ratio of compressing files has proven to be much effective than other tools. It is rightly positioned to become the next default file compressor even with the current support for this algorithm is quite low.

Image Optimization

If you are not accustomed with the optimization of front end, you must know that website images best serve the purpose. If your website is based on large number of high resolution pictures or massive images it will block the rendering process. Since, images if not optimized weigh several megabytes with high definition. So, you can enhance the performance of your website’s front-end with image optimizations.

There is a lot of information that is actually not relevant to the actual image. Such as the JPEG photos may contain camera specifications, location, date, etc. You can achieve optimization with tools when deleting this data and avoid the length of loading process. Optimus tool is used for optimization of PNG images via smart compression, while for JPEG it uses a lossy compression. In lossy compression image’s excessive information is removed, whereas in Optimus lossy compression there will be no loss of visual quality with definite level settings. So, you can have the high quality images with much lesser file sizes.

Minimalistic Framework

You can integrate a good framework in your front end to avoid several mistakes, except for if you are developing your website with your own knowledge. Your website may not need a range of well-known and large frameworks. So, you should sort out the requirements for your project before starting to work with the features that may keep your website lightweight. CSS, HTML, and JavaScript are mostly use for concise design framework. You can minimize your loading time with milligram, skeleton, and pure.

It is obvious that these frameworks are not at all replacement of efficient programming, designing and maintenance. You can think of a framework like a new house, which is clean but empty. So when you start to put inn stuff, you make sure that it looks desirable rather cluttered. Only you are responsible that excessive codes, HTTP, and large images do not ruin your website.



CDN is a great way for you to just use it as a static resource apart from its hot libraries. CDNs may differ in the configuration methods and control. You can change DNS records to set the CDNs for pointing out your domain as well as rest will be handled by CDN to decide if it is dynamic or static. You can choose the specific resources using CDN, as well as you don’t need to use the local URLs to update webpages or upload the static assets. You can do this using CDN provider. CDN checks for the closest location to route a request for the user in all cases. You try a number of CDN planners and providers that are absolutely free including Microsoft Azure, Akamai, CloudFlare, and Amazon CloudFront.


HTML5 has matured with a high number of new features as well as open up the chances for greater possibilities. It is a way of creating caching features and building offline that facilitated the service workers. You may need some technical expertise to integrate these features, while the advantages worth effort. You web application can work without a network to a certain degree when you add some offline capabilities to it. The load time for page can be instantaneous with the integration of service workers for requesting cache and responding.

Content Adaptation

You can enhance the content based optimization with the help of uses cases that are mostly used in a device. It is better to research or prioritize your use cases that may appear most likely as you do not know which users will want to use your app on which devices. It doesn’t mean that you will need to ignore the other use cases. Google’s search results illustrate this idea in action. Obviously desktop and mobile users have different experience as there is a difference in the surfaced information. In mobile, information is directed towards local results more than desktop as well as other priorities are different. You may observe demotion in mobile, however it is available to reflect as per the likely use cases, while accommodating the others.
