1. Hello friend.
    The code works well in computer, but in mobile device the ads don't appear.
    When the ads are included with a box widget, is easy to include the code "mobile=yes", but following this method I don't know how to do it.

    Could you help me please?

    Thanks in advance.

    1. It will work in mobile site too. You just need to enable custom template for mobile site. Follow this post for further info http://www.the101helper.com/2015/05/how-to-optimize-blogger-blog-for-mobile.html

    2. Hello Fahim. I already did that. My blog already was enabled with "custom template" for mobile site, but the ads don't appear in mobile.

      Until now the only way to show ads in mobile has been including the ads in widget blocks and including the code "mobile='yes".

      Do you have other idea to solve this?
      Thanks so much for your great help.

    3. Yes, use below code to show ad below post header in mobile:

      5b:if cond='data:blog.isMobile == "true"'6
      /////////YOUR AD CODE//////////

      Replace 5 with < and 6 with >

      But make sure the ad code between this code will show only in mobile for desktop u need to add another ad code

  2. Thank you Bro.
    As you know, adsense allows only 3 ads units per page. I can include more blocks, ones for mobile and some others for PC and configure the blocks to show maximum 3 blocks. But anyway, in the html code will be many blocks, maybe 6 or even more.

    Does Google sees as a problem to have a big amount of blocks in the html code?
    I'm not sure if this is against the adsense rules.

    Thanks for your great help.

    1. No bro and Google now allows unlimited ads per page, search about it.

  3. Hello. When I search "'post-header" code, this code only appears one time. The code doesn't appears two times.
    I tried putting the code above this one but didn't work.

    Can you help me please ? thanks in advance.

    1. Normally we have 2 or 3 post-header but if you don't find it change your template or email me at fahimraza101@gmail.com and send your blog link, I will help you.
