Application.cfm and SEO

My 10 years of experience with CF is strictly with intranet
sites, so search engine optimization has not exactly been one of my
priorities. I am now developing an external site for my
organization, and am curious about how I have been doing things.



For my intranet site, I have been placing my site's
navigation bar in the application.cfm page of my site. This, of
course, allows it to appear at the top of each and every one of my
pages. For my purposes, it works fine.



I had thought about using this approach for the external
site, and putting my keywords and META tags in that same
application.cfm page. This ensures that they are seen on every
page, easy to maintain in one place, etc. etc.



The problem with this approach (other than the rhetoric about
keeping application logic and presentation logic separate, etc.
etc) is that from what I understand, search engines despise sites
that have the SAME tags on every page of their site. If this is
true, I would not be doing myself any favors by using
Application.cfm for my META tags.



Is there a consensus about the benefits or detriments of
every page showing the same META tags?
