Why is indexing pages with obscure parameters?

Question

CMS

Good day. I went to the Yandex webmaster of my site on WP and saw in the list of indexing articles that, after the name of the article in the address, also have the parameters ?sa=X&sqi=2&ved=0ahUKEwiOpIett2q4AAhWFA5oKHTMRCDwQ9QEIDjAA
for example site.ru/kak-viigrat-million.html?sa=X&sqi=2&ved =0ahUKEwiOpIett2q4AAhWFA5oKHTMRCDwQ9QEIDjAA
The parameters are the same on all pages, the values ​​are different. What could it be?

Answer 1

1) Some plugin can add these values.
2) No link can be seen by search engines if there are no links to it from within your site (or external sites).
3) Set up canonical parameters - it merges all pages with URL parameters into one page. Thus, search engines will see URLs but they will not be unique (they will stick together with the main URL)
3rd point - the solution to your problem.
