Hi, I didn't tried adwords yet but I am doing some research and study even watch some videos in youtube and I just want to ask if how much do I bid on a certain keywords. Is there a 0.01 cents keywords? Thanks!
In theory, I think that is the minimum, but don't think like that - you won't get keywords for that unless you have a) an excellent site, with more relevancy to that keyword than anyone else has ever had, that has performed well in adwords for a period of time b) they're worthless keywords on the content network that will never convert.
Until you gain more experience, be careful paying more than five cents per click. Refine and narrow your phrases until you get a low rate.
A really good way I became familiar with AdWords and the right keywords to use, was to buy a few books off Amazon. If you read them cover to cover, you can become an AdWords pro in no time.
