Still real new at this. My question is there a way to get certain ads to show?

What do I need to do?

Right now I am doing post on Horror Stars Celebrity Bios for Halloween.

But No ads are showing for Halloween Costumes.

I don't want to write a post on Halloween costumes. But I would think that bios on Horror Stars would show some costumes ads.

It's like they should go hand in hand. Right.

Thanks in Advance
