Consider that there is an old blog, which has almost 10 or more images in every post they published. As everyone knows, WordPress creates an attachment link for every image we upload in a blog.
For SEO, low-quality pages are the biggest problem, so they redirected all the attachment pages to their respective parent posts or home page. Now there are almost 100K redirects in a blog which has only 20k published posts.
So my question is, will this affect SEO?
Of course, this number looks too large to me. What other ways we can use to solve this problem?
