Sanded Australia review for SEOmatic: AI SEO Optimizer

I used this app to help reduce the size of pics on the shop,worked well.. but don't let it change your alt text and photo names. We have completely dropped out of the image search in every cat that we used to be at the top of Google???? Now trying to work out how to reverse all this and the work to replace every alt text and image name is going to be a nightmare!!!!!!
