I asked Matt Cutts (Google Engineer):

Yahoo provides a robots-nocontent class tag that can be used to remove content from the page flow from being indexed (or used in determining a pages weight). Does Google support this tag? If not, are there are plans to support such a tag?.


He answered:

“We don’t current [sic] support that tag, for a couple reason. We think we do pretty well on detecting boilerplate (e.g. you’re not likely to run into any issues of duplicate content for header/footer type stuff). The other reason is that we haven’t seen a lot of sites using the tag after Yahoo mentioned it. Given the choice on where to put engineering resources, not a ton of people have asked for this feature.”


Good to know
