For example, a search for [charles darwin] in Google returns a Wikipedia result at the top. The result has the classic one line Sitelinks, but instead of the Sitelinks hyperlinking to different pages, they hyperlink to the same page, but anchor down the page to a specific section. For example, clicking on religious views anchors the searcher to the “Religious views” section on the page, by appending the # sign to the URL.
I believe Yahoo’s quick links have been doing this for a while now. Just try the same search for [charles darwin] but this time on Yahoo and clicking on the single link quick link to religious views, does the same thing.
Again, the one line sitelinks is not new, but the anchors feature seems to be new from a Google search page perspective.
