Thunder Page Speed Optimizer

The reviews are overwhelmingly positive, with many merchants praising the app’s ease of use, clean and user-friendly interface, quick setup, and noticeable improvements in store speed and performance. A recurring highlight is the support team, especially George/Georgi, who is frequently described as responsive, helpful, knowledgeable, and willing to go above and beyond to solve issues or even provide custom optimization help. Several reviewers also mention benefits to SEO, mobile performance, Core Web Vitals, and overall shopping experience, and some appreciate the free plan or good value for money. The negative feedback is much smaller but important: a few users reported serious technical problems such as blank screens, freezing optimization pages, failed loading, and theme/editor issues after installation or removal. Support responsiveness is generally praised, but a handful of reviews mention delayed replies or no response at all, which led to frustration. A few users also noted that results were not immediate or that the app required some support rather than being fully set-and-forget.
