How to automatically check the uniqueness of images on the site?

Question

Search Engine Optimization

There is a desire to audit the site for the uniqueness of images. The site was purchased so it is not known if unique images were used in the content. There are many images, manually one by one using images.google.com cannot be checked. Are there ready-made services that automatically scan and check all images for uniqueness?

Answer 1

So after all, if the site is old, then most of the pictures have already been copied and posted on the network. Now you can’t figure out where it’s unique and where it’s not. Unless manually by date of loading.
