 Hi guys,

 Weird one here that has been bought about by Google Search Console showing
 me Google is indexing hundreds of pages of my site.  I raised a
 [https://wordpress.org/support/topic/wordpress-treating-url-number-suffix-
 strangely/ support ticket] which resulted in the suggestion I raise it
 here.

 WordPress seems to handle any number on the end of a valid URL as if it
 were a real page, and show it as a separate page, complete with canonical
 URL tag.

 Example:

 Real Page: http://www2.cuny.edu/academics/academic-programs/

 Fake page - does not actually exist but returns a page:
 http://www2.cuny.edu/academics/academic-programs/2/

 I have used these pages from the wordpress.org sample section as my
 example to prove its happening not just with my own install (I also tested
 with default theme & all plugins disabled).

 The result of this craziness is that Google will index these many variants
 of the same page, causing duplicate content issues.

 I would have expected WordPress to redirect to the actual page, which
 would have its own (correct) canonical.

 Thoughts? Help!
