Possible spider mite infestation

Hey everyone I need some good pics of a spider mite infestation. My plant has lower leaves turning yellow with some little spots on the top side. I looked with my pocket microscope and saw all sorts of little spots on the underside and some were black dots that looked clustered up. I sprayed with neem just to be sure but if this isn't my problem I'd sure like to figure it out so I can save the plant and not have an infestation to fight off. Please send pics so I can compare to my plant.

Thanks man so the little yellow spots are the mites themselves or are they the eggs? I really appreciate your help.

google spidermite pictures that's what I would do. Pull off a leaf and look at it for a few minutes and they will move around.
