so there are tons of keywords that are not bidded so you can be the first with 5$ per 100 clicks and i doubt that if you description be targeted that i cann't get 1 sign up with that se 100 clicks
about hitbots - yea it;s pain in the ass but i think there is some soft that can protect you frof this shit and most sites bid 20-40$ per 100 clicks i guess they have some profit if they bid so high even in 1 place - (by the way overture highly recomend you to be the first
) may be overture hitbot by itself in order to earn some money
