Tiny SEO Speed Image Optimizer

What I like is: optimised images saved back to the backend of Shopify, same with SEO optimisations. So even when you would delete the app, these optimisations stay there! They were able to point out that a wrong mapping of product brand was caused either by another app or the theme itself. It worked out that the Theme was to blame. And fixed the issue (with the help of the theme developers) on Google Search Console and indeed this app is doing it the right way because the issue is fixed according to Google. Website became noticeable faster with all optimisations. Support is rather fast in answering questions as well. And if you take in consideration the price for a 2 year plan: it becomes unbeatable! So therefore a 5 star!
