I can see this topic has been raised before, however that was about six years ago and I did not find a solution to the issue.
One of our clients run an online clothing store and as you know images are quite important for them. The problem we are facing is that none of their product images are currently being indexed.
Our alt tags and image file names have been added. The images are also listed in the products xml sitemap, however they still do not get indexed.
Will creating a separate image xml sitemap by uploading a plugin and adding the sitemap to the robots.txt resolve this issue?
