The easiest way to place ads is with a plugin, which i’ve already used.
But i wanna make a a/b tests for adsense, which i can’t find any plugin for, so i have to do it my self in the code.
And if i try to put a test in the text widget, then it just end up showing both ads and some part of the code

But thanks about the content-single.php! 🙂

I’m not sure what you mean about post formats, but i’ve copied content-single.php and content.php

I still can figure out where to put the ad code.

I have made my child theme, but still don’t know about the code.

First of all i just want it on a single post. This is my code for single.php:

Where should i then add the code from adsense; if i want it in the beginning and in the middle?
And what should i write to allign it in the middle of the browser?

My site is http://veisworld.com/
Using the Twenty Eleven 1.2

But i can try adding it into the loop then

Do you know where to insert it for getting it in the sidebar? (i know you can add a text box widget, but i want the ad in the code, again for a/b)
