Going wide with Yahoo?

Hello Jeremy and thanks for all the info...

I've been listening and watching the webinars with Amit and you about PPC.

I used your coupon to sign up with Yahoo and have launched a couple of campaigns. One is a CPA and another my own product that drives people to my eBay auctions after they check out my landing page.

I know this is not exactly the laptop approach but I wanted to get up to speed on PPC and also test an affiliate product by direct linking.

If I may, I would like to ask about the CPA offer concerning PPC and going wide vs. going deep at first

My question is keywords and cost analysis.

On a $1.30 CPA PPC campaign...where do you want the cutoff to be on what you'll accept to pay...for instance when I get CPC down to .18 no one is clicking, very little impressions...

I'm sure I can get some action if I go up on the CPC. But before I go that route I was thinking it could be my keyword selection or my approach to this, etc... or if it's a matter of going up on the CPC, what would a reasonable limit be on a CPA $1.30 zip.

I remember your webinar where you stated expect to spend some money testing and to set some aside. I don't mind turning the bids up, I just want to make sure I'm approaching this correctly.

With the going wide approach, it seems there is a chance that money will be spent on keywords that are really not related to my product. So is this a matter of knowing where customers are in the buying cycle?

I understand the approach from your super affiliate, I'm a little hazy on the going wide approach as it applies to where the customer is in the buying cycle or does that even matter on the wide part?

I hope all this makes sense......

Thanks,
Gary
