What is this fruit? Is it edible?

Considering how many of them I’ve seen growing on the ground where I live in PA, it’s likely a mock strawberry. The plants grow on runners on the ground and have yellow flowers with five petals that become the fruit. The seeds come off easily when you rub it.
They’re safe to eat (wash them and make sure your lawn isn’t treated with chemicals though) but lack the flavor of real strawberries. I’ve eaten them before.
The fruit doesn't get much bigger than the one you're holding either. Here is a zoomed-in picture from Wikipedia:
It looks quite similar to the fruit of arbutus unedo (a.k.a. strawberry tree), which is edible:
