The PageSpeed Insights performance score for mobile rose from 12 to 82.

The PageSpeed Insights performance score for desktop rose from 47 to 94.


Having a fast website is important for both search engine rankings and user experience, and global telecom business TeleForwarding wanted us to improve its website speed performance on desktop and mobile.


Over a twelve-week period, we analysed the Core Web Vitals for Teleforwarding. We used the PageSpeed Insights tool to pinpoint problems with page loading. We captured a score of 12 on mobile and a score of 47 on desktop – both of which are poor results.

Paying careful attention to both mobile and desktop scores, we looked at different recommendations to make a positive impact to the score – with very successful results.

After just three months, we saw a big improvement in the website’s speed on both desktop and mobile!
