The list usually goes: Google, Yahoo, MSN, Ask, Teoma in terms of top
5 to optimize for. AOL uses Google, although their script changes the
results slightly (reportedly), so no reason to optimize for AOL as you
want to optimize for their supplier.
Ask and Teoma use a very different algorithem, supposedly, in
comparison to the top 3 search engines.
