“Must have for any e-commerce site"

What do you like best about Nostra? 

The team behind Nostra is phenomenal, from the initial calls to trial and setup, they have been absolutely great. It was such a breeze to get setup and getting any changes done. The app does what it says, it installs in minutes, and gets working pretty much immediately. You can definitely see an increase in store conversions, about 15-20% increase from what we see. We will need longer testing periods to confirm but so far so good.

What do you dislike about Nostra?

Their pricing is little high especially if your web traffic is on the lower end but if you have over 50,000 views a month, then it is worth every penny. If they offered smaller tiers to start, that would be great too. Regardless, it should pay for itself.

What problems is Nostra solving and how is that benefiting you?

Faster web page speeds, maintaining it above 80 and 90's which helps with the user experience significantly and thus creating more sales through better conversion rates. We often have our site optimized but they tend to fade over time. With Nostra, you can rest assured that your page speeds are always at its best.

“Best in class onboarding and a super fast site”

What do you like best about Nostra?

The Nostra team were fantastic during onboarding. We dealt with the same people throughout the sales process right through to launch. I'm not a super 'tech-savvy person, so I really appreciated the time and care they took to explain how their product worked. Most importantly, though, our website is now super fast. Over the years, we've manually tried to speed up our site, but I've really noticed a difference. Once Nostra is up and running, you can 100% notice the difference.

What do you dislike about Nostra?

There's not really any downsides. Our website is a LOT faster, and their support is super responsive.Review collected by and hosted on G2.com.

What problems is Nostra solving and how is that benefiting you?

Like most e-commerce stores, our website is loaded with images which slows down the site speed. Nostra has increased our site speed which has increased our conversion rate. There is a noticeable difference in our website speed before and after installing Nostra.
