Top 5 Tools to Track Website Performance

Marcel Casella March 16, 2019

Did you know that 53% of visitors will leave your website if it takes more than 3 seconds to load? Or that a 1-second delay in page response can reduce conversions by 7%?

As the statistics above show, more often than not how fast a site loads determines if we choose to stay on it or move on to another.

But what does that mean in terms of money?

Let’s assume your online store’s daily average sales is $10, 000. That 1-second delay would transform into over $250,000 lost revenues every year.

If that’s not enough reason to be on top of your website’s performance, here is another:

Google has always considered loading speed one of the most important factors when ranking sites and presenting them to users.

And from 2018, mobile loading speed also factors into the ranking equation. So, if you want your site to stand a chance at showing on the first page of search results, speed should be one of your main concerns.

For some users, loading speed is more important than how a site looks. This has a lot to do with the fact that the internet has gotten us accustomed to instant gratification. Humans are already hardwired for it, but it just so happens that the digital era made it possible for us to find or get what we want almost instantly. If we don’t get what we want out of a click quickly enough, we’ll simply move on, and so will our customers.

You want your customers to stay on your site long enough to see your products or services, and even make a purchase. That’s why providing a seamless experience for them is paramount to increase your sales. If a site is quick to load, it is more likely that visitors will stay on it, read its content and take action.

The good news is that there are plenty of online tools that allow you to assess how fast your site loads. They can also help you gain insights on how to improve your website and optimize its loading speed.

Here is a list of some of the best load speed testing tools available:

1.   PageSpeed Insights (by Google)

PageSpeed Insights (PSI) offers data on a website’s real-time performance both on desktop and mobile devices. The tool provides a report that includes Chrome User Experience Report data to show how fast your site is and how you can improve it.
