Last week I used: <!--google_ad_section_start--> <!--google_ad_section_end--> to assist AdSense crawler to focus on trageted content on my main index page after I restructured the layout and added new written content. The top line of code starts at the beginning of sentence "cartoons available" and bottom line of code after wording: "planning to drive across" (just before the reddish brown text). It seems to have worked, as ads in that 336 wide rectangle now pertain more to the content. QUESTION: Is it acceptable to add that same code within other parts of same page? Such as for that other 336 wide rec. at lower right in same page?
