Performance used to be an afterthought but now things have changed significantly. It is no more just a technical concern, performance now needs to be measured, monitored and reviewed continuously. So, we’ll create a front end checklist of the things that you have to keep in mind from the start of the process to the final release of your website to improve performance.
Develop a performance culture
Usually, front-end developers know what exactly the problem is but the absence of alignment between marketing and design team makes it hard to achieve long-term performance. So run performance experiments and measure the outcomes both on desktop and mobile.
When creating a performance environment, choose, set up and maintain your tools. Also, keep progressive enhancement as the guiding principle of your front-end architecture. And make sure you choose a strong performance baseline for maximum results.
Set a goal to be faster than your competitor
When setting the goals, you need to be better than your competitor that means at least 20% faster than them. To achieve this, you have to study your primary competitors and gather metrics of their performance. However, these goals need to be realistic that you can really achieve.
For instance, if you to want to make your interaction with the customers smooth, the interface should have 100ms to respond. Any longer than this and your customer will think of your app as laggy.
Select the right metrics
Not every metric is important for your website. Study the metrics and figure out which ones matter the most to your website. Focus on these metrics specifically. Usually, these metrics are what the most important pixels are and how you can start rendering them.
This will help you in getting the best optimization target for your ongoing efforts. Don’t just start focusing on full loading page time; prioritize as per your customers. A few metrics worth targeting are Time to Interactive, First Meaningful Paint etc.
Collect data of your audience
To start with this thing, you need to first choose the devices to test on. This device needs to be a representative of your audience. You can begin with a good range device such as a Samsung and then switch over to different networks as in WiFi, 3G and 4G.
It’s entirely possible that some of the optimizations would be simply beyond your budget and scope. Use this list as a general guide and create your own list of issues and more specific test and monitor your own projects to identify the problem areas before optimization.
