My homepage has been getting less-relevant adsense ads.
Page source shows that the start & ending codes for ad targeting happens to be placed just one line after the other, as follows:
Line 351: <!-- google_ad_section_start -->
Line 352: <!-- google_ad_section_end -->
Above 2 lines of code doesn't encompass the Main Column, obviously.
How do I modify the placement of above ad targeting codes such that H1 or H1 & H2 are being encompassed?
