how this adword keyword works? It activate it when I add key word at $0.05, after 2 day later it said I need to bid $5.00 per click to activate the keyword.
it went to the high value due it detected that your keywords do not have a good "Quality score" in your account. Try to write more relevant ads (better CTR%) and try also destination pages more relevant (that has the keyword in landing page) For more information for improving your "Quality Score" see the Adwords help.
