Where do utm tags come from in Yandex.Webmaster indexed pages?

Question

Search Engine Optimization

A bunch of new ones appeared in the webmaster's indexed pages directly with utm-tags, duplicating the old ones and themselves, where do they come from? That is, why do they get into the list of indexed pages?

An example of an indexed page from Webmaster:

https://site.ru/catalog/section/?utm_source=yandex&utm_medium=cpc&utm_campaign=XXXXXXXX&utm_content=XXXXXXXXXX&utm_term=Заголовок%20рекламы&region=XX&region_name=Город.desktop.Город.&source=context.images.yandex.ru&_openstat&XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX&yclid=XXXXXXXXXXXXXXXXXXX

It is

Array
(
    [utm_source] => yandex
    [utm_medium] => cpc
    [utm_campaign] => XXXXXXXX
    [utm_content] => XXXXXXXXXX
    [utm_term] => Заголовок рекламы
    [region] => XX
    [region_name] => Город.desktop.Город.
    [source] => context.images.yandex.ru
    [_openstat] => XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    [yclid] => XXXXXXXXXXXXXXXXXXX
)

Answer 1

1. In robots.txt, use the Clean-param directive . Example:

User-agent: Yandex
Disallow:
Clean-param: utm_source&utm_medium&utm_campaign&utm_content&utm_term&yclid

So you can check robots.txt https://yandex.ru/support/webmaster/indexing-optio...
2. Specify the canonical address of the page

<link rel="canonical" href="http://www.example.com/blog"/>
