Tips to Minimize HTTP Request and Increase Google PageSpeed.
The world travels easily. The majority hurry to be the ones to see, play and review it when the new iPhone rolls out.
People are glued to their TV screens when there’s breaking news, waiting for updates as broadcasters rush to be the first to deliver. It’s no wonder that when they search the site, people expect the same kind of agility and speed.
They want their user experience undisturbed so that they can quickly access the details they are looking for. For sites with slow load speeds or insufficient performance, users today have little patience.
Around half of internet users assume a page to load in 2 seconds or less in a study conducted by Akamai. Some of these users usually leave the site if it isn’t loaded within 3 seconds.
Another alarming statistic is that 64% of shoppers who are unhappy with the experience and loading time of an online store will take their company somewhere else. This means that you not only lose your current visitors and lower conversion rates, but you end up losing traffic from other users who have recommended your website to someone.
Seconds make the difference on this day. You should no longer accept unoptimized pictures and databases to downgrade your website. The users expect your web-pages to load quickly and if they don’t, they won’t stick around.
Let’s take a look at ways of optimizing your website for the highest performance with that in mind.
1. Minimize requests for HTTP
HTTP (Hypertext Transfer Protocol) queries are recorded when a file, page, or image is fetched from a web server by a browser.
Such queries occasionally take about 80% of the load time of a webpage, according to Yahoo. The browser also restricts requests to 4-8 simultaneous connections to the server, which means it is not a choice to load 30+ assets at once.
This implies the more HTTP demands you need to load, the longer it will take for the page to go and retrieve all of them, the longer the load time of your web page.
How you can reduce HTTP requests
Although it seems to restrict the designs of your pages by keeping them basic, you can use many techniques to Minimize HTTP Requests in an attempt to relieve the browser.
Although this can be complicated if your stylesheets and scripts differ from page to page, it will eventually improve your load times in the long run by managing to combine them.
Using queries to load only what is needed: If you notice that you only need to load those images on the desktop or only need to run a particular mobile script, it can be a great way to improve speed by using conditional statements to load them. In this way, the browser is not required to load a range of scripts or images that are not useful for those devices or viewports.
If you think a few of your pages are extremely image-heavy, attempt to eliminate some, particularly if their file sizes are high. Reduce the number of images you use. Not only can this help reduce HTTP image requests, but erasing distracting images that do not correlate to your written content, can enhance your UX.
CSS sprites: So if it applies, you can combine pictures in one sprite sheet fairly frequently across your web site and access images via CSS background images and background-position to prevent anyone browser from trying to constantly recover several images each time certain pages are loaded on your site. In this manner, the browser only went to retrieve the one that can be used on the page multiple times by correctly placing the correct image in view for each page location.
2. Using CDNs and deleting unused scripts/files
More than likely, that web server would not be in close enough proximity to several of your users.
It is simply not a feasible choice to minimize this gap by spreading the content through a number of geographically distributed servers, and it is a little too difficult to implement.
This is where a network for the distribution of content (CDN) comes in. A CDN is a series of web servers that are spread around several locations so that users can deliver content more effectively.
When published, CDNs are usually used only for static content or data that will need to be touched.
Based mostly on the user’s estimate of network distance, servers are chosen. For instance, the server with the fastest response time and/or the least network hops is selected.
Larger companies prefer to have their own CDN, while medium-sized companies will use a CDN provider.
Smaller businesses can find a CDN excessive or beyond their budget, so using websites such as CNDjs that have a JS and CSS files and system libraries may help you avoid hosting those files with your own servers whereas increasing their loading speed.
If you notice that the website of your business might gain from using CDNs, take this time to also review your site to identify if your site has unused scripts or CSS files.
Although making your programmer go through your website and review each page is the easiest (yet most time-consuming) thing, there are a few tools like UnCSS that can delete unused styles from your website and reduce the size of your CSS file.
