Random ad doesn't work

I insert adsense, and I want ads displayed between posts on my home and category pages. On those pages, with it set to display 3 ads with the random setting, the three ads are always displayed in a row, either in the first three or second three spots, and always below the content.

I tried using top, random, and bottom placements, but that was even worse, with one ad above the content (which in my case is a video), one below, and the next above the next video. All cramped and messy looking.

Using random is still the best option.

I haven’t found coding to work well, and no other ads plugin I’ve found displays ads between posts. At least the ads themselves change. lol
