We believe that this article gave you a basic understanding of website testing and website testing tools and technologies. You are now in a position to select the most appropriate Website Testing tools based on your requirements.


What are Website Speed Testing Tools?

There are multiple reasons why people shop at one online store rather than the other one or choose a streaming service over their competitors. Pricing, quality of content, quantity, etc. are important but what makes a consumer lose patience? You guessed it right! Speed of the said website.

Website Speed Testing tools refer to tools and technologies that test the speed of the website at which it loads and reacts to input from the user.

What should you consider while using Website Speed Testing tools?

We believe it is utterly important to understand while figuring out how and why speed affects delivering an enhanced user experience. A few of the most common performance metrics to watch out for are:

  • HTTP Headers

  • Resources that take too long to load

  • Page sizes, speed, and number of requests

  • TTB and FMP

Why should you use Website Speed Testing tools?

The user experience while moving through your website should be a good enough reason. A slow-performing website will frustrate users as users have multiple options when it comes to the consumption of content that would send them somewhere else.

A responsive, faster, and more efficient website will keep them focused and engaged with your content rather than waiting for your web page to load.

A slow-loading website also negatively impacts SEO which can negatively affect your ranking on search engine result pages (SERPs). Page performance and page experience should be among the top optimizations to consider.

What factors may impact my Website Speed Test results?

As per most research and surveys, more than half of the web users expect a website to load within three seconds or less which may seem like a minor thing, but it isn’t. Most online shoppers wouldn’t go back to the same e-commerce website to shop again and would tell their friends about their poor experience, given the speed of the website.

However, certain factors may impact your Website Speed Test results and they are:

  • Volume of Traffic

  • The connection speed of the user

  • PC Cache

  • Hosting/Server

  • Browser used by the user

  • File Sizes/Types

  • Plugins

If your website speed test results are poor, don’t panic. Follow the recommendations of the speed testing tool which suits your requirement the best and work on it.

Why should I be concerned about my website’s speed?

The speed of your website is one of the most important factors which Google considers while ranking your website. The importance of page loading time has drastically increased over the past couple of years. A slow-loading website typically means a slower crawl rate which would even delay the speed at which Google will index your web pages.

To boost traffic and organically get a higher ranking, you will have to increase the speed of your website and web pages. A fast website without broken links is a user-friendly website.

Why is measuring website speed critical?

A positive user experience depends on the speed of the website. If your page loads slowly, your conversion rates will likely remain the same. In general, if it takes more than three seconds for your website to load, 40% of visitors will leave.

What does website performance testing entail?

Performance tests can show you how your system behaves so you can observe how it scales as pressure is put on it and how resources are deployed to meet that demand, as well as verify that your websites and applications perform well even when there are significant increases in concurrent users.
