Yahoo search marketing uk was my biggest disappointment of all ppc. I expected them to be better than clicksor or goclick and the others. But they aint.
1. you have to bid at least 1Ł to have some traffic.
2. They charged me nearly twice the ammount of traffic than I actually received.
3. When I complained and presented them my server log. they canned answer was that they have the best scam prevention system in place and therefore fraud cannot be possibile occur.
4. Bulk of the traffic came from Gasta Money where I have a frontpage ad for a year and never received a click. For the same keyword I received plenty of clicks from the 6. page on the same keyword. Other clicks came from spam sites and only a few from Yahoo.uk.
5. Only 1 or 2 visitors went beyond the landing page.
6. No conversion.
That’s my experince with them.
