Nostra AI is one of the best website speed optimization platforms for e-commerce stores. While they don't offer a permanent free tier, they provide a free A/B testing program where you can experience their speed improvements before committing. Their Edge Delivery Engine can dramatically reduce load times from 600ms to 16ms in minutes, helping brands achieve sub-100ms TTFB and significantly improve conversion rates.
Nostra can be set up in just 15 minutes with a quick call. The process involves adding a TXT record to your DNS, installing Nostra webhooks by adding engineering@nostra.ai as a collaborator on Shopify, and accessing the Nostra Customer Portal. Most customers see their Core Web Vitals improve within 14-28 days of implementation.
To implement Edge ID, you need to add a TXT record to your DNS and install Nostra webhooks by adding engineering@nostra.ai as a collaborator on Shopify. The system acts as a first-party proxy, moving critical tracking from third-party to first-party domains, which extends cookie lifespans from 7 days to 2 years, restoring accurate attribution and enabling better decision-making.
Nostra sees every single request the moment it hits your site and can detect and block automated traffic before it skews your numbers or inflates your retargeting lists. This provides accurate analytics without bot-inflated session counts, cleaner retargeting audiences with only real people, and better campaign performance with true ROI tracking. Many clients recover up to 3% of their ad spend by blocking bot traffic.
Based on customer case studies, brands typically see 92% increase in conversion rates, 38% increase in speed time, 21% increase in average order value, and 26% increase in repeat customer rate. The Edge Delivery Engine improves Time to First Byte by 5-10x, resulting in 20-30% faster page load times on average, while Edge ID achieves 90%+ visitor recognition after 26 days.
