Question about Google Adsense ads based on content

[ginkgo]

I saw the following on a post. If you want to focus on getting the right ads with particular content on the page, Try using section targetting. This will tell Google only to display ads from the content contained in this code:

<!-- google_ad_section_start -->

<!-- google_ad_section_end -->

If you want to make sure Google doesnt display ads from a particular section of the content, use the following code:
<!-- google_ad_section_start(weight... -->

Does the above work? Also there is no end tag for what you want Google to ignore. How do you stop it. The 3 dots after weight must mean something.

You put weight=ignore after the section start so adsense will ignore the content in that section. Useful for stopping things like the sidebar and comments from influencing the ads, I think.

These are the correct tag pairs:

<!-- google_ad_section_start -->
<!-- google_ad_section_end -->

<!-- google_ad_section_start(weight=ignore) -->
<!-- google_ad_section_end -->
