What are Page Rankings?
A page ranking allows you to pin results at the top of the list for specified search terms. Using specific search terms and/or an audience, it is possible to manually select particular results to be shown above the organic list of results. Page Rankings are engine specific.
Example
When a visitor searches for search terms like “Job” or “Career”, you can configure a page ranking to always display the page about open positions as the first result on the page, even if the page content may not seem the best match to the search engine from a logical standpoint.
