With the launch of Google’s AMP scheme, the discussion over web page loading time seems to have obtained a new ground altogether. Everyone appears to be in maddening insanity to optimize site and reduce page load time. Page speed is a measurement of how quick the content on your page loads.
What is Page Speed?
Page speed is often involved with “site speed,” which is the page speed for a sample of page aspects on a site. Page speed can be defined in either “page load time” or “time to first byte” (how long it needs for your browser to receive the first byte of information from the webserver).
You can assess your page speed with Google’s Page Speed Insights. Page Speed Insights Speed Score consolidates data from CrUX (Chrome User Experience Report) and reports on two significant speed metrics: First Contentful Paint (FCP) and DOM Content Loaded (DCL).
A one-second delay in page load time:
- 11% fewer page views
- 16% reduction in customer satisfaction
- 7% loss in conversions
A few more seconds could have a large impact on your ability to engage visitors and earn sales. In another research, the relationship between load times and conversion rates showed a 27% decrease in conversion rates with just one more second of load time.
How Can You Speed Up Your Website?
Let’s begin with some of the things that have the greatest impression.
- Use CDN :Content Delivery Network (CDN)carries the static content of your website closer to the global users, using point-based servers. In other terms, it reduces the distance between the real hosting servers and the destination computers, by placing several connecting or point servers in different parts of the world. These servers then cache some of your website’s components and distribute them to their ‘nearest local servers’. This method not only assists in decreasing both page-load times and the bandwidth charges but also reduces the pressure on the original server while enhancing the customer experience.
- Minify CSS/JS files:
Every time you visit a website, there’s a whole set of technical stuff going on back the scenes. While news and images are loading on your screen, in the background your browser is requesting and receiving files.
These HTTP requests affect page load speeds and, ultimately, change the user experience, bounce rate, and SEO. The fewer HTTP requests your site sends to the server, the faster your site will load.
They also continue to the number of requests your site does every time a user visits it. You can decrease this number by “minifying” and linking your files. This reduces the size of each file, as well as the total number of files. Minifying a file includes removing unnecessary formatting, whitespace, and code.
- Apply Caching : Ensure that your mobile browser uses local memory to cache resources to avoid additional server requests.
- CSS Sprite :
By using the advantage of CSS sprites, the user will nevermore have to wait for individual images to load. Once the main “sprite” has loaded, all the other relevant images in the sprite are loaded as well. Load time is decreased as your browser has to fetch information;
If your browser requires to load 50 small images, it still has the overhead of 50 requests. CSS sprites reduce this number considerably. The image to the right is a sprite we began using 13 individual icons from the FamFamFam Silk Icons Set. As a sprite, they are 4.51 kilobytes in size (4,620 bytes), however, the thirteen icons figure 7.95 kilobytes (8,144 bytes) if their file sizes are calculated. When analysing the pre-loading effect, the file-size savings, and the fact that your browser only has to do one HTTP request instead of thirteen, the benefits are very simply illustrated.
- Install Page Speed Module on Server : For Apache installation of the PageSpeed module, it is really simple as Google has already implemented pre-compiled packages for PageSpeed. Presently, the PageSpeed module is supported on CentOS, Fedora, Debian, and Ubuntu. It supports both 32 bit and 64-bit versions of Operating Systems. The PageSpeed module can be installed from both the latest stable version and beta version. It is prescribed that in a production environment you use constant mode only.
- Improve Server Response Time : To improve your server response time, see for performance bottlenecks like passive database queries, slow routing, or a shortage of adequate memory and fix them. The optimal server acknowledgment time is under 200ms.
- Enable GZIP Compression on Server : When a web browser visits a website it checks to view if the webserver has GZIP enabled by viewing if the “content-encoding: gzip” response header lives. If the header is detected, it serves up the compressed and fewer files. If not, it serves up the uncompressed data list. If you don’t have GZIP allowed, you will most probably see warnings and errors in acceleration testing tools such as Google PageSpeed Insights and GTmetrix.
- Apply AJAX to Speed Up :
- Applying AJAX will improve your mobile site fetch the data from a web server without essentially requiring the page to be renewed.
- It enables your mobile site to fast load and fill in updated content while the viewer is still browsing through your mobile page.
- Add Expires Headers to Leverage Browser Caching : Expires headers speed up your site in two steps: –
- They decrease the need for users to download similar files from your web server twice.
- Secondly, it reduces the number of HTTP requests that need to be done, further speeding up the time it needs for the page to load.
Conclusion: Making your page load times to where you want them to be is a challenging endeavour, but will have an important positive impact on your overall site performance. It’s also essential to remember that while all of the tips on this page can benefit you achieve your site speed goals, you don’t need to implement all of them today. To prevent this from occurring, you need to understand the different determinants impacting your website loading time.
