Speed Up Your Shopify Store With Thunder Page Speed Optimizer

Boost store speed, AI SEO visibility, and LLMs discovery. Monitor pages and optimize safely.

Keep your store speed fast, easy to discover, and ready for AI / LLMs. Thunder continuously monitors how real shoppers experience every page and proactively optimizes slow pages, images, CSS, navigation, and third-party scripts. It identifies delayed clicks, layout shifts, broken links, and hard-to-crawl content, then prioritizes what needs attention. Automatic image compression, ongoing monitoring, and safe previews help maintain performance without constant manual work.

See and track page-level Core Web Vitals based on real shopper visits.
Find slow pages, SEO barriers, and content AI agents may struggle to access.
Improve website speed with CSS, third-party scripts, and image optimizations.
Control lazy loading, predictive preloading, and page-slowing scripts.
- Preview every optimization safely before publishing to your live store.

Thunder Page Speed Optimizer has been a helpful tool for improving my store’s performance. It’s easy to use, and I like that there’s a free plan available to test the features. A useful app for anyone looking to make their Shopify store faster and provide a better customer experience.

Thunder made a noticeable difference to our store speed. The setup was super easy, and we didn't need to make complicated technical changes. Our pages load much faster now, which has improved the overall shopping experience

Must-have app if you care about speed and conversions. Our site performance improved almost immediately, and the team helped us optimize things we didn’t even know were slowing us down. Easy to use and great support.
