10 Best Website Speed Test Tools

The speed of a website is a very critical factor in its success.

In fact, faster loading websites are in for higher SEO rankings, lower bounce rates, higher conversion rates, longer visitor duration on site, as well as offer better overall user experience, and engagement.

So, it is in your interest to take advantage of the best website speed test tools and achieve optimal performance.

Today we share with you 10 Best Website Speed Test Tools with which you can analyze your website performance and take corrective measures for optimizing your website speed.

It is important for you to know that the average amount of time that most Internet users can tolerate concerning slow loading websites is only 2 seconds. This itself spells the importance of website speed.

So, it is very important for your website to be reliable and fast loading.

In fact, Google has incorporated website speed as a ranking factor. It wants that your site should load fast for your visitors.

What is Page Speed?

Page speed determines how fast the content of your page loads.

In fact, it is described as “page load time” – the total time is taken for displaying the content of a specific page or “time to the first byte” – the time taken by the browser for receiving the first byte of information from the specific website server.

Irrespective of how you go on to measure page speed, having a faster page speed is in your own interest. It is found that faster pages load the better on SERPs as well as convert better.

So, you should be focusing on page speed (and, as a result, website speed) if you want to make your online venture as profitable as possible.

Why is page load speed so important?

It is in your interest to enhance your page load speed as much as possible. In fact, it is very frustrating for online users to find that it takes ages for pages to load.

They get disillusioned to see a slow loading page and decide immediately to shut down that site. It means a lost opportunity for you.

Moreover, slow loading pages are a key reason for high exit rates.

Internet users expect that a website should load within 2-4 seconds. If it takes longer than that, they get frustrated and prefer to click away from that site looking for a better page load performance.

Moreover, more than three-quarters of web users would not return to a website that takes more than four seconds to load.

So, if you want that you do not lose out on your visitors, it is important for you to ensure that all of the pages of your website load within a maximum of two to four seconds.

SEO Best Practices for Increasing your Page Speed

According to Google, site speed (as well as page speed) is used by its algorithm for ranking pages on SERPs. Moreover, Google measures time to the first byte when it considers page speed.

In addition to this, a slow page speed makes search engines to crawl fewer pages with their allocated crawl budget.

This could lead to a negative impact on your indexation.

Plus, page speed is closely related to user experience.

Pages that have a longer load time tend to suffer from high bounce rates and have low average time on page.

It also has a negative effect on conversions.

How to Speed Up Your Website

Here, we list out some of the ways by which you can increase your page speed:

Enable Compression

You can use GZIP Compression for reducing the size of the files on your website by almost 70%.

It helps in reducing the size of your CSS, HTML, and JavaScript files that are more than 150 bytes.

However, for compressing image files, you should be using a program like Photoshop. It helps to retain control over the quality of the image.

Minify JavaScript, HTML, and CSS

When you go on to optimize your code (remove commas, spaces, and other unnecessary characters), you get to increase your page speed.

You should also remove code comments, formatting, and unused code. In fact, Google has recommended the use of YUI Compressor for both CSS and JavaScript.

Reduce Redirects

In case of a page redirect, your visitor has to wait for the HTTP request-response cycle to complete.

For instance, if your mobile redirect pattern takes the following form: “example.com -> www.example.com -> m.example.com -> m.example.com/home,” then these two additional redirects cause your page to load slowly.

Use Browser Caching

Browsers cache a lot many information such as style sheets, JavaScript files, images, and more. So, when a visitor comes to your site again, the browser doesn’t need to reload the entire page.

You can use one such tool as Yslow to make out if there is an expiration date set for your cache.

Then you set your “expires” header for knowing how long that information can be cached. In most of the cases, a year is a reasonable time period unless your site design changes quite often.

So, when you use browser caching, your website can make use of cached version instead.

Improve server response time

Your server response time depends on the amount of traffic you receive, the software used by the server, the resources each page uses, as well as on the hosting solution.

For improving server response time, you should check for performance bottlenecks such as slow database queries, slow routing, lack of enough memory, and go on to fix them. The optimum server response time is well under 200ms.

Using a CDN (Content Delivery Network)

Content Delivery Networks (CDNs), also known as content distribution networks, are networks of servers that is employed for distributing the load of delivering content.

They go on to store the copies of your site at multiple, geographically distant data centers so that users can get faster and more reliable access to your website.

Optimize Images

Make sure that the images you use on your website are optimized. The images shouldn’t be larger than they need to be.

They should be in the right file format. PNGs are generally suited for graphics that have less than 16 colors. JPEGs are good for photographs.

The images should be compressed for the web. You can use CSS sprites for creating a template for images that can frequently be used on your site.

CSS sprites go on to combine your images into one large image which can load all at once. It means fewer HTTP requests are thereby saving load time. Users don’t have to wait for multiple images to load.

You also need to compress images used on a web page. One can use image compression software to compress the image size without losing the image quality. One can also use software like Photoshop to compress image file size.

How is a Website Speed Test Helpful to You?

Website Speed Test Tools are helpful in more than one ways.

Here, we list out some of the common ways in which website speed test tools are used:

  • They go on to pinpoint scripts, fonts, and plugins that cause load time issues.
  • They help in checking out the minification of your scripts.
  • They find out large images that result in bottlenecks.
  • They help out in determining render-blocking CSS or JavaScript.
  • Testing Time to First Byte.
  • They analyze total load times, page sizes, as well as # of requests.
  • They check performance from different geographical locations.
  • They check rendering speed in different browsers.
  • Analyze HTTP Headers.
  • They measure the performance of your CDN (Content Delivery Network).
  • They go on to verify whether the assets are loading correctly from your CDN.

Here, it should be noted that making your website load faster can offer you lots of advantages.

With a fast loading website, you can certainly get high rankings on SERPs. It leads you to achieve consistent conversion rates for sales.

It goes on to minimize bounce rates and can help in maximizing the amount of time that your visitors spend on your website.

Moreover, the website speed test tools that we have listed are the best way for optimizing the performance and speed of your website.

These tools go on to pinpoint stuff like custom plugins, fonts, code, scripts that lead to load time issues.

They can help you in locating large files and images that result in loading bottlenecks. Plus, these tools can analyze page sizes, load times, and various other performance-related tests.

Some Website Speed Concepts

Here, we put across to you some of the concepts behind website speed test tools so that you are in a better position to analyze the data and can go on to optimize your site accordingly.

It will not only help you to test the speed of your web host, but you can also go on to measure your CDN performance.

Time to First Byte (TTFB)

It is the measurement of the responsiveness of a web server. Specifically speaking, it is the time taken by your web browser to start receiving information once it has requested it from the server.

When you use a CDN, you can immensely reduce the impact of the load on your server, which in turn helps to reduce your TTFB.

Render-Blocking Javascript & CSS

Render-blocking refers to CSS and JavaScript that prevents your page from loading as quickly as it should.

Minification of Resources

It refers to the removing of unnecessary characters from your HTML, CSS, and JavaScript that are not required to load.

These include the following:

  • Whitespace characters
  • New line characters
  • Block delimiters
  • Comments

This helps to speed up the load time as the amount of code that is requested from the server is reduced. Here, tools like JavaScript Minify and Dan’s CSS prove immensely useful as they can remove all the unnecessary characters.

In case you are running WordPress, then using a plugin such as Autoptimize can be very helpful as it goes on to minify all the HTML, JavaScript, and CSS for you.

HTTP Requests

A browser goes on to fetch data from the server using HTTP (Hypertext Transfer Protocol). This can be termed as a request or response between a client and a host.

As a rule, more the number of HTTP requests that your web page makes, the slower it will load.

However, you can reduce the number of requests by adopting the following ways such as:

  • Combine your JavaScript and CSS files
  • Inline your JavaScript (only when it is very small)
  • Using CSS Sprites
  • Reduce the use of 3rd party plugins that make many external requests.

How fast your pages should load?

It is important to note that the negative impact on conversion rates is minimum (less than 5%) when page load time is less than a second.

When pages have load time of less than a second, any exit rates that do happen for these pages are a result of factors other than page load speed.

So, to meet your visitors’ expectations, you should try and achieve page load speed of 2 second or less.

It will help you in getting high conversion rates.
