WB 23 - Need help with a warning message

>> Warning : In order for the 'PAGE_QF2' page to be referenced by the search engines, the call to PageDisplay() can be replaced by a direct link. To do so, choose 'Display the PAGE_QF2 page' in the description of the 'LINK_QF2' control.<<

When this warning tells me I can (must?) replace a PageDisplay(Page_QF2) with a 'direct link' - what is direct link referring to - searched the tutorial docs, didnt find anything.

Thanks in advance

Don
