Drop in Page Impressions

Hey everyone, I just found this forum, I need help with understanding the Page Impressions. I just recently added some new keywords to a few of my campaigns and the over the past couple days (right after I added the keywords) my page impressions have dropped signifigantly. My ctr is still normal, but I'm getting less than half of the impressions (and thus clicks) as I have been for over a month. It doesnt seem to be coincidental. I also added some keywords to multiple campaigns, and was wondering what happens when you have the same keywords on say 3-4 campaigns? Do you start driving the price higher and compete against yourself for rankings? I also cannot always find my ads when I search my keywords, even though it says in my stats page that my average position is around 6-7. Do they not put your ads in 100% of the time? Shouldn't they do this until your maximum cost per day is met? My max cost per day is set at $30 and it never even comes close. usually around $3. I need help!!!

Thanks

Have you checked the status of the keywords? Sometimes google will slow or disable your keywords based on their performance. If your impressions have only been down a few days I wouldn't get too worried. Give it a few more days.
