Will my SERP go away if I sign up for Yahoo PPC?

[halcyonlost]

Hey guys,

I'm ranked on all SE between page 1-3 onall my keywords. However, I want to put some money into PPC. If I sign up for it and lets say I use the word "truck financing" even though I am already ranked 20, will yahoo take down my rank? Same question for MSN...

Regards.

NO. PPC will not hurt your ranking. In fact in the long term it will give you more exposure and help your ranking.
