How to remove duplicates in Wordpress?

Question

WordPress

Tell me please. The site has a problem with duplicate pages. Those. one and the same page is available at several addresses. For example
/?p=1063551
/yandeks-market-proveryaet.html
This is the same page. And this problem is not for all pages. If you try to take the ID from the admin panel and go to some pages, it will redirect to pages with the address /yandeks-market-proveryaet.html?p=1063551 Please tell
me which way to look?

Answer 1

Everything goes with a 302 redirect. The search engines understand it.
But you can install a SEO plugin - it will determine the canonical URLs or not.
In general, this is not a problem. This is how it always worked and the search engines did not swear
