On tt-pro, the main page still opens in Russian, although the specification states that Ukrainian should be the primary language, and there are already two specific 404 images in the articles. It is dangerous to focus solely on PageSpeed: pages can be accelerated, but duplicates can remain and the logic of redirects can be broken.
I will start with a backup and verification of URLs, 301, canonical/hreflang, and robots as one scheme. Then I will address speed, HTML errors, alt, Schema with ratings, FAQ, and llms.txt. I will handle AMP for news separately to avoid touching the catalog unnecessarily. I will show the results before/after for PageSpeed and technical checks.
I have been working with OpenCart since 2013, and I do not modify the core without reason. I can outline the order of work on your 12 points directly in the chat.
