Extremely poor docs.python.org SEO performance.

Describe the bug
docs.python.org has atrocious search performance on Google. It's so bad that I suspect Google is actively downranking it for some reason.

To Reproduce
Search Google for virtually any Python documentation topic. The ones that drove me here were searches for [python set] and [python shuffle list].

Expected behavior
docs.python.org is the authoritative source for Python documentation on the web. I expect to find relevant results on docs.python.org somewhere on the first page of Google search results.

Instead, I find the opposite. For [python set] I expect to find https://docs.python.org/3/library/stdtypes.html#set
somewhere on the first page of results, but instead, the only python.org result I see is for the long-deprecated
Python 2 sets module --
https://docs.python.org/2/library/sets.html

For [python shuffle list], neither https://docs.python.org/3/library/random.html nor any other python.org result shows up anywhere on the first page.

Screenshots

Additional context
These results are egregious enough to make me suspect you're
being actively downranked for some reason. This isn't a request for general SEO optimization -- although that'd be a great project if someone has the interest -- but for a domain admin to try to use Google's search console (https://developers.google.com/search) to investigate if there's something egregiously wrong with an easy fix.

Google Search Console と、issue にある例のクエリおよび URL（Python 3 set のドキュメントと random のドキュメントページ）から始めてください。インデックス登録またはランキングの問題が結果を説明できるかを調査してください。一般的な SEO 改善ではなく、具体的な原因と実行可能な対処方法が特定された時点でのみ、issue は完了です。
