How to do clean-params correctly?

Question

Search Engine Optimization

There is a format link site.ru/category/subcategory/

A problem was detected in Yandex Webmaster, on pages site.ru/category/subcategory/and site.ru/category/subcategory?start=13. The error is that the page data contains the same title and description, but the content does not change.

It's simple, you just need to specify clean-param in robots.txt, but the problem is that there is a useful get-param on the page site.ru/category/subcategory/article?start=13and Clean-param: start /category/*it will not work without harming the useful one.

Tell me, is it possible to somehow flexibly specify the clean-param parameter so that it does not fall under the distribution site.ru/category/subcategory/article?start=13?

Answer 1

Not clear, please provide more examples.
It sounds like there are pages site.ru/category/subcategory/, and there are duplicate pages in the get-parameter site.ru/category/subcategory/article?start=13. How to close pages with geth without closing them?
