The main search sites in Ireland are really directories though I don't really know what kind of traffic they get. The ones below are the ones that seem to be the most recognised.
http://whoisireland.com (Automatic .ie/CNO inclusion/user sub)
http://www.indexireland.com (User submission)
http://www.irishsearch.net (ODP/User submission)
http://www.niceone.com (User submission)
http://www.browseireland.com (User submission)
http://www.kompass.ie (business)
http://www.doras.ie (User sub/paid inclusion)
There was an attempt at a Yahoo directory clone (http://www.doras.ie) by the main telco in Ireland but it stagnated after an attempt to introduce paid inclusion for some categories and a lack of investment. Most of the directories have been squashed by Google. Traffic now seems to be based on search engines rather than directories.
As for Scotland, I'm sure there is a good opportunity for a good search engine/directory but I don't know of any at the moment.

(1) whoisireland.com is currently on the first March run spidering all the .ie websites). It has two search engines - the first indexes .ie websites only (daily/weekly) and the other indexes all Irish websites (.ie/com/net/org/info) in depth (monthly).
