How to close pagination pages from indexing?

Question

Search Engine Optimization

There is a site, on ImageCMS. How to close pagination pages from indexing.
links:
m-investspb.ru/balka-dvutavrovaya
m-investspb.ru/balka-dvutavrovaya/15
both are indexed in Google, and this is bad - duplicates.
And there are many such pages m-investspb.ru/balka-dvutavrovaya/1-81 (there are so many pagination pages here). There are a lot of sections, how to close them from indexation?

Answer 1

In robots.txt add:
Disallow: /balka-dvutavrovaya/*

Answer 2

Use the canonical tag and don't need to close anything.
If there is content on the page, such as a description, then make it available only on the first page.
PS. Where do you get pagination from and why?

Answer 3

In my opinion, the best solution would be rel="canonical" (if you leave pagination pages). It is strange that users do not have the opportunity to scroll through these pagination pages. It is doubtful that customers need such lists in one column with prices. Hypothesis: can it be more convenient to make it in 2-3 columns without prices and place lists on 1 page without pagination?

Answer 4

1. Set up the canonical URL rel="canonical"
2. (Control) add the following line to the robots.txt file:
Disallow: /balka-dvutavrovaya/*

Answer 5

1st option https://support.google.com/webmasters/answer/16637...
2nd option - robots meta tag with the noindex parameter
In robots, you cannot prohibit what has canonical, Google will not be able to recognize the instruction from this page, since access for the crawler will be prohibited..
