Similar sitaution to Phil. As an example we are the only people in the
whole world to make and sell  a 'mother of pearl banana bar' which is
why we are #1 in all the search engines for those search terms, except
Google where it is not to be found. We have nutured publicity through
all the normal chanels, trade shows etc and we are known for this
unusual and unique item. The problem is internet users see that Googles
results do not show any site related to this specific item, so they
either assume no such item was ever made or they turn to the other
search engines for help.
As i see it, the reason the page (forgive the link)
http://www.silverstall.com/bodyjew/banana-bar_mother-of-pearl_8.html is
not in the googles main index is that it has been supplemented based on
the cached page 'as retrieved on 2 May 2006' That page was updated a
long time ago, so why does it take so long for Google to re-examine a
supplemented page. I know our initial page was poorly titled and lacked
contenet however is the any way a review of supplemental pages could be
speeded up to say once a month?
