When I searched for “desktop” on Yahoo! I noticed the following two ads in top section position 1 and 3.
“HP Desktop with Intel® Technology
www.hp.com Get free shipping and an all-in-one printer with select HP desktops.”
and
“Desktop Computers from the HP Home Store
www.hpshopping.com Shop HP desktops from $249 and save up to $150 in rebates from HP.”
The first one took me to the page
http://welcome.hp.com/country/us/en/prodserv/computers.html?jumpid=ex_hphqglobal_coreSEM/computing
while the second one took me to
http://www.shopping.hp.com/webapp/shopping/store_access.do?template_type=landing&landing=desktops&aoid=33323&kw=desktops
It appears, the main HP guys and the shopping division of HP guys are not collaborating and so bidding for the same keywords which could inturn unnecessarily increase the cost.
Whether my above observation specific to HP is true or not, the main question is, large organizations with several divisions responsible for promoting different LOBs may end up spending money on ads individually unless there is a centralized policy. This is no different from the classic Purchasing Spend Consolidation. Instead of goods or services it’s ads (another way to look at it is the keyword ads as a service).
