Sorry, forgot to check this part of Oprano again. It truly depens on what products you are promoting.
If you are promoting UltrAllure for example, the pheremones some of the common keywords woudl be
women/woman can both be used here
attract women
pickup women
pheromones
pheremones
cologne
dating
divorce
seperated
single men
single man
single women
blind date
And any other keywords you can relate to a situation where someone would be using pheromones.
As for the penis enlargement products it is self explanitory.
penis surgery
bigger penis
increase penis size
small dick
grow penis
incease penis girth
increase penis length
bigger dick
bigger penis
And any other variations relative to what someone would be searching for on PE products.
My best suggestion is to not count on QUANTITY rather quality. Don't overbid outrageous amounts and hope for 300 sales in a month, rather bid low $.08 per click with great descriptions pre-selling them on the product. Yes, you will probably only get 50-100 hits a day maximum if you take some time to develop a strong campaign but it will be much more profitable.
50-100 hits a day could easily lead anywhere from $40 - $100 in profit from commisions. At $.08 per hit you are only paying $4.00 - $8.00 to get this traffic.
Another strong suggestion on top of presellign them with a well written pre-sell is to direct them to a splash page that refreshes in say 5 - 10 seconds and forces them to the url of the product you are trying to sell. On this splash page promote the product again, and talk about hwo you used it yourself and saw amazing results, etc... By this time they have been pre-sold twice are auto refreshed and are very intrigued by the product, you have a much better chance of making the sale like this rather than directing them straight to your link for the product
I'll try to check back more oftne in this area in case anyone has any questions.
