Why should you care

Because you care about your visitors

What matters and why?

What matters is your users' experience. At Storff, we believe the most crucial part of their experience is how fast your pages become 'available'. Not just how fast they load, but how soon can a user interact with them. For those technically inclined, yes, we mean 'DOMContentLoaded'.

What should you do?

Track real visitor experience for every single page view. Track changes over time and ensure all your visitors have the best experience possible.

And yes, we can help you with this!
