We fear that the proverb "slow and steady wins the race" does not apply to website speed. According to Google, if your website made by web development company Kolkata takes more than three seconds to load, you will lose approximately half of your visitors.

A slow-loading website appears to be a recipe for disaster. When you run speed tests and see your website's performance plummet, you'll want to figure out what's wrong.

In this post, we'll look at the eight most common causes of a slow website.

How can the performance be tested?
Before we can look at how to improve performance, we must first understand how our website is currently performing. There are numerous tools available for this purpose. Google Page is a well-known example of such a tool. This tool can provide a comprehensive view of the various performance metrics. As an alternative, we can use the Lighthouse Chrome extension.

Along with the Google page, the Chrome network tab can be used to quickly verify the site's performance and analyze a few metrics.

1. Overflowing HTTP Requests
HTTP requests are when a browser sends ...
... information about a specific webpage to your servers. Your website may contain numerous image files, CSS, and JavaScript, resulting in multiple HTTP requests.
Browsers send several requests to access these files whenever a visitor lands on your website. These requests overload your website, causing it to slow down.

How to Fix It?
Sprites can be used to reduce HTTP requests.
Reduce the size of the javascript and CSS files.
Reduce the number of files on your website.

2. Your Site Includes Unoptimized Images
Images attract more visitors. However, a large number of unoptimized images is one of the most common causes of a slow website speed. There's no denying that these high-resolution images can consume a lot of bandwidth.

Uploading high-resolution, large-sized images and then scaling them can increase the overall size of the web page. As a result, your website may take longer to load than usual.

How to Fix It?
No image should be larger than 1MB.
Use JPEG or WebP file formats for larger images.
Perform tests to determine image sizes.

3. JavaScript Issues
The availability of jQuery and JavaScript plugins makes it easier to include dynamic content forms on websites. However, incorrect implementation can cause your website to lag.
It can take some time to load, interpret, and execute JavaScript and jQuery. As a result, if you're using different API calls for rendering, it could be another cause.
Website owners must conduct a JavaScript audit for this purpose.

How to Fix It?
Asynchronous loading is required.
Think about using Google Tag Manager or Segment.
Examine all JavaScript scripts.

4. Presence of Flash Content
Flash content was popular among website owners five years ago. It's great for increasing your website's engagement and interactivity. The bad news is that flash content could be another cause of your website's slow loading speed.

You can significantly improve the performance of your web page by removing any Flash content or reducing file sizes.
Using HTML5 alternatives is another way to make your website faster than before. These alternatives can assist you in replacing all existing flash files.

How to Fix It?
Look for HTML5 alternatives.
Avoid using flash content because it is large and has poor performance.

5. Not Using Caching Techniques
Caching is a common technique in the world of web development. It can vastly improve the performance of your website made by website design company Kolkata. You're missing out on the good stuff if your website isn't actively caching.
This technique allows you to cache some of the most frequently accessed data.
This cached memory serves all subsequent requests for the same data piece. So, what is the bottom line? Caching can aid in the acceleration of data retrieval funnels.
Your website has a better chance of retaining its performance if you use HTTP/browser caching. It can cut latency and improve UX.

How to Fix It?
Cached data from images or any static content should be cached.

6. Unclean Codes
Unclean codes may appear to be very common and unproblematic. However, it is mostly these unclean codes that cause website slowness.
Inline stylings, unnecessary comments, empty lines, and excessive white space can all increase the size of your website's stylesheet.
By removing such elements and compressing the code, you can improve the overall load speed of the web page.
This is known as minifying in the language of web developers.

How to Fix It?
Avoid using inline CSS.
Pay attention to the coding style to avoid unnecessary calculations, loops, and so on.
Avoid creating multiple CSS stylesheets.
CSS and JS should be optimized.

7. Too Many Third-Party Ads
The majority of visitors find these pop-up and in-page ads annoying. Ads could be a source of income. However, losing traffic should not cost you anything.
Too many advertisements on your website can cause it to load slowly. Furthermore, advertisements increase the number of HTTP requests. When dealing with website slowness, limiting the number of ads can be beneficial.

How to Fix It?
Use them judiciously

8. Skipping CDN Service
A CDN service is a network of independent servers that are used in various geographic locations. Visitors are served by these separate servers, which provide web content.
The nearest data center will provide the requested content after analyzing the website visitor's geographic location.
The use of regional data centers reduced round-trip time (RTT). As a result, website visitors can access the content in much less time.

How to Fix It?
Cache frequently accessed data in geographically dispersed locations.
Bottom Line

Several factors contribute to your website's slow speed. Sometimes it is a single factor, and other times it is a combination of factors. When it comes to assessing the pain points of your website's speed, you should leave no stone unturned.
