BidAdjustments –Sometimes you will get the same amount of clicks with a much lower bid. Remember don’t change your bid, just duplicate your working campaign and set it a lower bid and track performance. Now monitor your take home net and decide which campaign will make you the most money in the long run. Sometimes you’ll besurprised how greedy these ad networks are with their bid prices, unlike Google most ad networks don’t charge you just a penny more over the top bid, butcharge you the actual bid amount you place!
新人,还没有bid过。所以上面一段看的不太明白。。。前面说了dont't change your bid. 后面又紧跟着lower bid...
