About Thunder Page Speed Optimizer

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.

I tried few speed optimization apps before Thunder, but this one is definitely the one that gives you the most extensive data based insights into issues and which pages are slow! The automatic speed optimization are a lifesaver for a store that constantly makes changes on the website!

I reached out both times with no response back. I uninstalled and reinstalled the app thinking a crucial update was missed; however there was no change. App was uninstalled permanently and other venues h...

I hate giving poor reviews, but this app simply isn't working at all. At first I only saw a blank screen when opening the app. Ok, the app support responded quite fast to solve the issue and confirmed it was a bug on their/Shopifys side. But then the optimization page just freezed and nothing happened. I didn't see any kind of progress on the dashboard or in the history tab. And now I'm back to se...

The only true benefit using this app was compressing the css file and nothing more...
