@darlene-tidwell Hi Darlene
There is no real standard – it will all depend on your page, but a good guideline would be around 10-20%.
I have been tracking mine now for 8 months and I average towards the top end of that, although some weeks I can have upwards of 30%+.
Just remember that it will fluctuate a lot, so the best way to measure it is to keep track of it.
