I need advice anything I can get...does google ppc work and convert well enough? are there any other ppc that work as good?
I prefer yahoo. Yahoo seems to convert better but you have a hard time getting clicks that charge less than 10 cents.
hmm well what are average costs of keywords? are they all different and does it matter what you bid at?
it really matters what the subject matter is... mortgage is expensive, others are less... you can only tell after you create the campaign and start placing bids. I would say start as low as you can and increase if you get no impressions
Depends whether it will work well and the average CPC on the niche, keywords, knowledge of adwords, etc.
