FB + Adwords - What is your best?

Hey, what is the lowest you paid for a conversion? I mean how much you paid to make a certain amount? People keep saying average profit margin for ppc is around 35-40% of the total ad spend?

Can you give some tips who are doing high in even numbers?

Bumping.

I can tell you for dropshipping. I don't know if it is an indicator on the PPC market but it can give you some points.I have a friend who earned a lot from dropshipping a sort of lamp and he told me that in order to sell one lamp for around $30 he had to invest $10 on each sale.

I know another person who sells jewelry and for every $55 jewel she sells it costs her a little more then $10 not including all the upkeep and inventory costs. She is using a warm audience which was a look-alike of people who already bought from her. I think your numbers are about right.

So the tip I got from them was on facebook, make sure you are putting a big budget each day ( facebook gives preferences to people who spend more) and it might also be relevent for google daily ad spend.
