Sherpas: Smart SEO

Highly recommended app for those who want to quickly set up alt tags , meta tags, and json-Ld mark up. To set alt tags for 3000 over products with more than 20 pcs for each product, it took me about 10min using Bulk edit function. Not to mention product token system which helps users to allocate different tags for each respective product is outstandingly useful. As to Json-LD mark up, it is mostly all-auto, and seems there is no room to tweek.
