Google advised blogger to place the "AdSense Linking Code with Google Analytic" at the most top part on your blog page. Which means, immediately below the 'Header' section.

How to do that?

(ON YOUR BLOG LAYOUT PAGE)

- Click 'Add Gadget' link either at Sidebar or Footer section
- Click 'HTML/JavaScript' on the 'Add A Gadget' pop up panel
- Paste your blog 'AdSense Linking Code with Google Analytic' into the compose box
- Click 'Save'
- Drag the saved gadget template slightly below the 'Header' section.

Finally, do not forget to click the 'Save' button link for your blog layout.

ALL DONE.
