Thunder Page Speed Optimizer

I highly recommend using the app and working with George. He helped me with optimizing my store and resolved critical issue with CLS (visual stability problems). I think an app like that is the future of online store optimizations. I must also add that I am a newbie to subject like this, I always feel dizzy while talking with developers - but not with George. He has high communication skills and I understood everything he said and every process he showed and explained. I appreciate the experience and results.
