Every moving thing on the planet does the same thing. However the net effect is
zero, because "what goes up must come
down". The only way these things might have net effect is if they come from
space.
Even so, the effect is still totally insignificant, due to their small mass
relative to that of the planet.
Don't forget meteors/meteorites also move the planet, and they have been
bombarding us for billions of years.
The motion of the planet is also influenced by the gravitational forces of the
other bodies in the Solar system, in fact
by that of everything in the Universe.
If no one clicked on ads companies would stop paying for them. :)
