Say you've got 100s of sites. Do you use the same theme for all of them? Would that look suspicious? I've got a bunch and I keep trying different themes/colors/whatever but one keeps having above average performance so I keep changing the rest to that layout/design/style. Is it going to trigger any red flags at Google if I have hundreds of sites in different niches all with the same color/theme/design? They all use adsense btw.
