The speed of your site has a significant impact on its success. Google has confirmed page experience as a ranking factor, and slower pages cause visitors to switch to competitors. This directly impacts conversion and bounce rates and, ultimately, revenue. Add to this that slow sites likely have higher content and resource storage costs, and it’s clear that the speed of your site can seriously impact your bottom line.
Lumar gives you not only full Lighthouse performance reporting at scale, but critically the details you need to understand the issues and take action, while improving collaboration across web development teams. All of which helps drive a high-performing, revenue-driving site that delivers a great experience.
