Cromojo is the best! I can't tell you how much time and money was saved with Cromojo. The setup only took minutes but the benefits were immediate. Everyone I convinced to use Cromojo is absolutely happy with their decision.

Why use revenue analytics?

Why website monitoring matters

Protect your revenue.
Every minute of downtime, an expired certificate, or a slow checkout costs you sales. Monitoring catches these issues before your customers do, so you keep the revenue you have earned.
Find problems before customers report them.
A broken link or a "not secure" warning erodes trust quickly. Cromojo flags issues the moment they appear, so you fix them first instead of hearing about them in a support ticket.
Keep your pages fast.
Page speed affects both conversions and search rankings. Lighthouse audits and Core Web Vitals show exactly where your pages slow down, so you know what to improve.
Never get caught by an expiry.
Expired SSL certificates and lapsed domain registrations can take a site offline without warning. Cromojo alerts you well ahead of either, so nothing lapses by surprise.
Stay covered as you grow.
One dashboard watches every site you run, so nothing falls through the cracks when you add more.
