He he,
putting perlmonks into the title might seem ok but will only suffice if the search bots look for "is /can be part of other words" which they apparently don't do by default.
But there are meta-tags that could be added (only on "The Monastery Gates" page). Look at the source of the page you get when you hit perl.com or perl.org and you'll see:

<META name="description" content="The official Perl home page, run by 
+O'Reilly. Contains documentation, news, and links to a variety of res
+ources, including the Open Source Perl conference." />
<META name="keywords" content="o'reilly network,o'reilly,perl,perl dev
+elopers,perl programming,software,learning perl,programming perl,regu
+lar expressions,perl algorithms,perl 5, mod_perl,perl for win32,open 
+source" />

Just overlooking it I count ten times the word "perl" and only once "mod_perl".
Search engines examine title, description, keywords, and Content. But if you look at perlmonks.org (or .com's) site how often do you find the word "perl"?grin
I counted alike 3 times.
Well if a search bot is rather smart than he will exclude double links, as for example Cool uses for Perl at the top and in any other place at the same document.
Note, "The Monastery Gates" is the only place to add these meta-tags as the major search bots will not follow links to scripts. This problem has also been discussed regarding how to find nodes at perlmonks.org using a search engine as google for example.
Can anyone remember the node? Sorry, as I remember a fellow monk set up a "static" mirror of a lot of perlmonks nodes to make them searcheable. Sincere excuse to the unnamed, but I simply forgot.

Have a nice day
All decision is left to your taste

Update
Thanks blakem, which is now not unnamed anymore, for poiting to his node about Making perlmonks seach engine friendly.
