For Blogger sites, you will need to manually install the widget onto your template for it to display beneath each post on the article pages.
Go to the “Layout” page in your Blogger admin and remove all of Content.ad gadgets that might currently be installed on your layout.
Go to the “Template” page and select the “Edit HTML button” to edit your site’s code.
Paste your Content.ad widget’s installation code after the following code:
<b:includable id=’comments’ var=’post’>If the code above doesn’t work, please try this one:
<b:includable id=’comment_picker’ var=’post’>
After you paste your widget’s installation code, be sure to click on the orange “Save Template” button and check if the widget appears on your site.
Given the variety of Blogger templates, these instructions may or may not apply to your template. If you run into any issues, please email firstname.lastname@example.org for help.
