I am a grand-fathered ($30/month pro plan) Yotpo user and I wish I left sooner. Yotpo is out of touch with the majority of Shopify store owners and uses antiquated, slow loading scripts that ruin user experience and hamper SEO.
Judge.me has a FAST loading reviews system that does everything Yotpo does and more. I installed Judge.me at 1AM today and the developer was replying to my questions within minutes, even helping me install the badges to match my theme properly.
This is an excellent app that outperforms Yotpo at a fraction of the cost. Support this company!
