My goal is to fix the blog pagination duplicate content issue in Google Search Console, in order to avoid indexing page 21 of my blog. To do so I use the Google Crawl URLs Parameters tool see image below.

My permalink structure needs to stay as is: domain.com/%postname%/

My pagination needs to stay as is: domain.com/blog/page/2, domain.com/blog/page/3

Since the only way to tell Google about pagination pages is via parameters, see below image,

I came up with the idea of adding an additional pagination parameter to my current blog pagination.

My goal is to set blog pages to have a parameter attached to it:

domain.com/blog/page/2?pageid=2, domain.com/blog/page/3?pageid=3

in order to tell Google to index and pass the juice from all the blog pages to one only page: domain.com/blog
