I’ve been using the ALTstar, Alt Text app on my Shopify store and it’s been a huge help. Before this, I had to manually add alt text to every single product image, which was so time-consuming. Now the app does it automatically and saves me hours of work. What I really like is that it keeps the alt text relevant by using my product titles, so everything looks natural and clean. It also makes me feel good knowing my store is more accessible and SEO-friendly without me having to constantly worry about it.
