Use a CDN: It is strongly recommended to use the Content Distribution Network to speed up website loading. It entails seeing your details all over the place, ready to be shown in every region. It reduces the time the server takes to transmit the data to the remote browser. As the name suggests, it is a network of servers that hosts the static files for quicker distribution.
Minify Markup, CSS, JS: These are the previously described “static files” that contain all the information on your page-content, formatting and relations. When Google recommends that you minify a file, it means removing all useless material, such as comments within the text, extra lines or gaps, etc. Using fewer lines of code to decipher would make the spider crawl the web even quicker.
Browser Caching: Browsers can store files to make pages load easier when users access them again.
Optimize Images: We need to compact images to the shortest possible scale. Initial photographs do not weigh more than 70kb and 10kb for thumbnails. Look at how much your pictures weigh and you’ll be surprised to see how much speed you can increase only by reducing their bulk!
Enable Gzip: This is just as critical as minimizing data. If you have ensured that all of the above are minimized to a minimal, the next move is to gzip the files: compact them.
Improve First Time Byte: This word has also been adopted. We want to reduce the time it takes for the browser to receive the first byte of information from the server by optimizing the backend code or by purchasing faster servers.
