This app is amazing and so easy to use. It has saved a ton of work and time spent optimizing my site. I highly recommend it to anyone who is serious about building a successful ecommerce site. Thanks for the support!
I used this app to add alt tags to my photos. Setup was easy and done in minutes. Can't answer yet whether it will help with image SEO, as I'm writing this same day as I installed app. Only time will tell. But in terms of ease-to-use, it gets 5 stars.
Does exactly what it says, works great will highly recommend. I have over 8000 products images and it completed quickly within minutes.
