Adsense Publishers may not place ads under misleading headers or titles as this may confuse users into thinking the ads are actually site links related to that header. 48 hours to fix the issue or else account in danger. Now my blog has this design to clearly elaborate to you - What do you say? Is this placement of 336 x 280 incorrect?
No the policy says "Misleading Headers" not titles of your blog post... You can not say "Current Best Offer" as the title of your right panel... But you can use term "Advertisements"if you wish to add a title to Right Panel.
