hi, ive got a music site, which i use adwords to advertise. ( to test before more ads are bought ) well i was advertising with them, but over the the first week the price gradually increased. which is fine as weekend prices shoot up. the second week i tested all keywords (weekday) some had few advertisers, some had only me. the next day the ads weren't being showed. I looked at my account the price had risen. i needed to increase my default price.even on the keywords i was the only advertiser. what i did was choose completely different set of keywords. And left them on for a couple of hours. I then went back the and checked my orignal ketwords, the price has fallen to the original price!! I dont know if this is A TIP but it worked for me. anyone know why this happened? or similar thing happened to them?
