Hi,
I have noticed the same thing occuring, only in Yahoo, i set up a campaign a while ago and left it as i had set my price per click low, but over the last few days or week i have been getting a load of clicks mainly for one betting keyword. My google analytics doesnt show the same amount as what Yahoo is saying but i have anothr hit tracker and it does show that the page is in fact getting the hits, in regards to accounts i have seen an increased number, it could be down to yahoo or as cheltenham starts my organic and google adwords traffic has also increased. I did not alter anything but then all of a sudden yahoo started sending me loads of clicks. Like 80 plus per day. Do you think it is a competitor clicking your add or a yahoo bot ? Can you see where your clicks are coming from ?
