What Datum is used by Google Maps?

Question

I am trying to convert vector shapefiles into Google Maps Datum using QGIS.

Do you know which one is the datum?

When I tried to convert them into WGS84 EPSG 3857, I could see that the shapes of the buildings didn't fit very well with those which are in Maps.

I've already tried using both EPSG:3857 and EPSG:4326. I don't have any good results.

Sorry, I've already tried.. and it doesn't work. I mean the shapes don't fit as well. — Guercio, Oct 18, 2018 at 16:53
what datum is your shapefile in? are you sure they're accurate? — NULL.Dude, Oct 18, 2018 at 16:54
... and don't expect the Google Earth Orthoimagery to be georeferenced "accurately". Sometimes they aren't even "ortho". You get what you paid for ... — AndreJ, Oct 19, 2018 at 6:01

Google use Web Mercator.

EPSG:3857 formerly EPSG:900913

But Web Mercator is a interesting projection system. As it uses WGS84 for calculations.

So you can try EPSG:4326

As you can see on sites like https://epsg.io/3857 or https://www.epsg-registry.org/ , EPSG:3857 uses the World Geodetic System 1984 (WGS84) as datum.
