Targeting by Search Engine?
MSN is female mostly… They are probably 30 years old and do less searches - BUT are ready to buy.
Shopping.com people are not spending as much, but the cost of that search engine is so cheap it pays off.
Myway.com is for young and 18 yr old males.
Ask Jeeves - Mostly young kids..
Don’t over look these smaller search engines - they are very targeted.
Landing pages from different Search Engines might need to be different. This could be done dynamically… hrmmmm. That is easy..
