A "shooting star" would have to be visible.  The smallest of the meteorite impacts would not necessarily be visible.  On an average day, I would think the number of visible meteorite impacts would be relatively small.  The numbers would be much greater during the meteor showers we have a few times a year.

There is something called micrometeorites.  According to Wikipedia, Earth is impacted with about 10,000 to 20,000 tons of micrometeorites each year.  If each weighs a fraction of a gram, then the total number would be much greater than 10,000 to 20,000 a day.  Most would never be visible when they came down.
