Ad Spider is a ´no bells and whistles´ program designed for one specific purpose - to find keywords or phrases where there are eight or fewer Google Adwords ad campaigns running. Find such keywords and you´ve found CHEAP clicks.
UPDATE: I´m finding SO many CHEAP keywords in my campaigns that it´s unfair!
USE this program. You won´t regret it- and any feedback to info @ mortgageadvice4free.co.uk Would really be appreciated.
