Why is Website Speed important for Everyone?
Before answer of these questions, you should keep this in mind that there is a lot of things on which website speed depends.
We will decode everything one-by-one. First, we should list out everything which is responsible to affect website or page loading speed.
- Server Response timing
- Location of Data Centre
- No. of requests
- No. of Images on Page

These are some major reason to affect page loading speed. Page loading speed is one of the major factors of On-Page SEO. There are many tools on which you can test your website speed or page loading speed.
Let’s analyze these major responsible factors for website speed:
Server Response Timing
Server response timing is the major reason to affect your website speed. Server response timing is the time which server takes to response for every request for your website’s URL or any page’s URL.
This is also called Latency.
It directly depends on your server type. Like figure for Shared Servers will be maximum and we all know that in terms of page loading speed we want quickest as possible. The difference in VPS (Virtual Private Server) and Dedicated servers could be very minimal or like nothing. It depends on the server configuration and optimization.
Cloud VPS and Dedicated servers are the best in terms of performance but they are very costly. So you can’t go for them until you don’t really need them.
Location of Data Centre
Its most simple thing to understand in this article that if data centre where website’s server hardware physically present is very far from you or visitor then it will take more time to load.
Suppose your data centre is located in North US and someone is trying to visit your website in New Zealand. In this case data have to travel such a long distance, so, it will take time. And your website speed will we little bit slower.
As you can see here the difference in page load speed for the most preferable website on internet www.google.com, from 2 different location. Because you only can choose 1 data center for your website, so this was a huge challenge to reach all over the globe at very very short time. Yes, you heard right, “It was”. Because in present time when every microsecond matters you can’t afford to be 1 sec. behind from your competitor. CDN (Content Distribution Network) service was introduced some years ago to solve this problem, and today approx. every large scale or globally famous websites use this to increase their page loading speed. Every large and Medium scale organization and companies using this service to reach everywhere at blazing fast speed.
You will get the answer of every important question about CDN like:
- My original Data Centre Location matters if I’m using CDN service?
- How CDN works?
- Should I use CDN service?
- How to calculate the exact Pricing for My used CDN service?
And much more.
No. of request
Now question comes
- what is no. of request?
- How requests affect Page Loading speed?
- What will be best No. of Request for great Website speed?
- How can I optimize this to increase my website speed or page loading speed?
A request is a query by the browser to the web server for each and every action, file, HTML request and for third party plugins and their actions too.
Less request will help you to keep your page loading speed higher. Like If in your website you are using a Facebook plugin which is showing your likes of your Facebook page on your website, then it has to fetch the data from Facebook so, it will create one more action.
So, there is one more tip you can uninstall unnecessary plugins to keep your website speed up.
No. of Images on Page
No. of Images is very major reason and approx. 90% site are slow down just cause of non-optimize or uncompressed images.
This factor alone can spoil your whole optimization and expenditure on best servers and fastest CDN service.
Undoubtedly Images play an important role to maximize the visual effect and call to action, but it can cost to your website speed.
Because nothing can replace images and infographics. Even according to different reports images increase visitor engagement about 30-40 %.
But sometimes you uploaded large size images, willingly or unwillingly. And Because Images are also counted as file requests, so it increases page loading speed. Sometimes it hampers website speed very badly.
So, what we should do? There is the very easy solution for this major problem.
Optimize and compress images before uploading to the websites.
If you’re on WordPress then, many third party plugins will make your work easier. Many of them are premium and some are free. I recommend to go with premium plugins, some of them really work great.
The importance of Image optimization and recommend Plugins for image optimization and compression in WordPress.
TTFB (Time to first byte)
TTFB is also a kind of parameter of website speed measurement. According to Wikipedia, TTFB means
“Time To First Byte (TTFB) is a measurement used as an indication of the responsiveness of a web server or other network resource. TTFB measures the duration from the user or client making an HTTP request to the first byte of the page being received by the client’s browser.”
Process and Time Taken under the Red boxes are TTFB.
Yes, in simple words, suppose your page size is 863 kb, you hit your URL into the browser and wait for load the page. Loading your page means browser have to download total 863 kb from the web server, that’s called Page Loading time. But in between, there is a lot of processes. Like if you simply hit the www.xyz.com then the browser will redirect to the web server and first determine this URL is http:// or https://, then another request will pass by web server if website URL is naked (without www). Then browser will start downloading the page’s content. Timing between hit the URL and the first byte is downloading from your webserver is called TTFB (Time to First Byte).
Simple to understand by its name alone. Right?
How can you find your website’s TTFB?
Go to tools.pingdom.com and enter your website’s URL for speed test. Then you’ll get these data….
When you’ll scroll a little bit then you’ll find the detailed time report request-by-request.
Time taken by the first two process is you TTFB.
