Find out exactly what is making your website slow

Your website speed depends on (1.) the quality of your code, (2.) greatness of your hosting and (3.) the number of concurrent users you have on your website.

With Supervisor you can continuously track the performance of your code and hosting. And predict the page load speed with high user volumes with easy 1-click load tests.

And to speed up your website we will pinpoint the exact area on your website that needs improvements and we will suggest you solutions to make your website fast.

Monitor the speed of your whole website

Running a website speed check against your front page is a good start. But how about your landing pages, important funnels and the e-commerce check out page?

Let us do the mystery shopping on your e-commerce funnels and track the speed of each and every page on your website. Automatically.

We will notify you when there is a real problem and highlight issues that needs to be fixed.

And if you want to dig deeper you will have a log of evidences from all the issues we find.

Learn how to speed up your website

We get it. Knowing you have a problem is only a start. But a good one.

We will tell you whether you should concentrate on the server or browser side for fixing the issue.

It might just be that your webhost sucks. Or that your devs should really limit the third party integrations they've added to your website.

We will pinpoint the issue to the request and file level. Maybe you have too big pictures. Or maybe there's just too many requests to the same host. Simple adding CDN could totally solve your problem. We will let you know.

How good your webhosting provider really is?

The website speed is affected by how many concurrent users you have at any given moment. But also how overbooked your webhosting providers servers are.

Be proactive and test what happens to your website on Black Friday, during a marketing campaign or when you finally go viral.

Is your e-commerce check out and important CTAs working properly?
It's easy to fine tune and monitor your websites frontpage. But what about the more important pages you can't put in to cache like shopping carts, check out pages and other CTAs? 

If you want to monitor a specific funnel you can teach our robots easily what to do. It is as easy as using your web browser. No need to start to learn coding.
Is bad performance destroying your conversion rates?
There is tons of research proving that page load time directly affects the user experience.


Best conversions are made with pages that load under 2 seconds. And you could lose up to 54 % of your visitors if it takes more than three seconds to load your website.

If you are not monitoring your website performance you might be losing a lot of business without knowing it.

Fast websites convert better

Be fast when it matters the most

It's easy to measure website speed when there is little or no users.

But it is more important to know that your website is fast when everyone wants to use it.
