At least 62% of visitors on my PWA come from Play Store, with 20% being labeled "unknown".

It really depends on your app, but many mobile users just search for stuff in Play Store first before searching on Google, and even Googling it will help as you will get a widget about your app (sometimes). The web version is (for the most popular queries) on average 1.6th in Google results.

Although the dataset may not be very large (10k+ installs shown on Play Store page).
