We have a new sitefinity website. We have blog posts whose urls are being appended with a ReturnURL parameter and this leads to the search engines seeing the same blog post multiple times as different urls.
Serious SEO issue here and just not clean structurally.
I discovered that this has something to do with the Comments being enabled. When looking at the page source I see that sitefinity is finding a restricted authentication issue and thus the return url parameter. See image attached.
By disabling comments I can avoid this, but ideally we'd have comments enabled. So please:
1. How to prevent this behavior?
2. Why is this happening?
Thank you -
