Highlight the important content of the page to ensure that the matching of AdSense accurate

Google AdSense ads will automatically locate the content of your Web page, but sometimes you may want to highlight or ignore portions of the page.
For example, you might want to highlight the first paragraph of an article or ignore the menu bar. With sector positioning, you can help us determine which part of the content is more important so that your site can display more relevant ads. Our crawlers will still view your entire site, but your suggestions will help us improve your advertising positioning.
You can use section positioning to make recommendations for any part of a Web page. However, you may be up to 1-2 weeks to see the change in advertising positioning. In addition, we want to make sure that your ads are effective, so our technology will detect whether sector positioning will improve the advertising effect, and will only automatically implement this feature when you can get more revenue.
The HTML markup used to emphasize a part of a Web page takes the following format:
The important part begins:<!--Google_ad_section_start-->
Important part over:<!--google_ad_section_end-->
The HTML markup used to ignore a part of a Web page takes the following format:
Ignore part start:<!--google_ad_section_start (weight=ignore)-->
Ignore partial end:<!--google_ad_section_end (weight=ignore)-->
However, it should be noted that doing so may lead to the display of less relevant ads or public interest ads. Please make sure that only the important part of the site-related content, manipulating the advertising positioning resulting in ads and your Web content is not related to Google AdSense plan policy.
