Repository start to gain users, contributors and stars without my promotion

I have a few open source repositories on my GitHub profile. Usually, they only get users when I mention them publicly. However, one of my repositories is gaining stars and users on its own. It is interesting.

Suddenly, people started:

1. Installing my pip package
2. Submitting pull requests
3. Starring the repository

GitHub repo insights traffic shows that most people come from Google.

At pypistats I can see much more activity after 2024-11-06 but I did nothing these dates.

Do you have any ideas about why this is happening? How does it work? Why were no visitors and changed in a single day without my activity?

How does it work on your repos?

I would love to create more useful open source solutions that people can find organically, without needing to promote it myself. But I still don’t understand how this process works.
