Mismatch in the position of objects on Yandex.Maps and Google Maps at the same coordinates?

I have coordinates in latitude, longitude format (in decimal) for a set of features. Initially, they were obtained through the Google Maps geocoder.
When displaying these objects on Yandex.Maps, the labels are shifted compared to the map compared to the output on Google Maps: for example, if in GM the label was in the center of the house, then in Y.Maps it is lower and to the left by 10-15 px.
Is there any algorithm for recalculating the coordinates so that they point to the right place on Y. Maps?

Maybe they have different datum. Pulkovo is used in Russia, WGS in the world

Your question is ideologically similar to the following: “I have a load on one scale, its mass is 1 kg, and on the other 1.2 kg. give the calculation algorithm. Both Google and Yandex use the same latitude-longitude coordinate system. And if there are discrepancies, most likely they have a jamb somewhere. I can assume that aerial photographs of your house were taken from different angles, and since the satellite is high, the influence of the atmosphere is significant and various deviations of the image may occur. Moreover, if you compare some other region, the deviations in the pictures may already be in the other direction. I would attribute this to the measurement error carried out by Yandex and Google. We do not have more precise military coordinates. So either introduce an artificial correction-crutch that only works for your area, or be content with what you have.

I asked you at the club and I will also ask here - where are the mistakes?
give a code or links where to look, indicate at what zoom you get an offset of 10-15 pixels, and so on.
Convert this mixture to meters and so on...
