I setup an Adwords account. It started out with what I thought was pretty poor performance; something like 3000 impressions and 6 clicks over 3 or 4 days. It was never hitting my max bid of $1, usually only about $0.44 per click but it was showing steady activity. Now for the past 3 days it has shown no impressions and obviously no clicks. It still shows my budget at about $195. Also the keywords thing has me a bit confused. There is a Google tool that suggest keywords for your site and somewhere in the documentation it says there is a limit of something like 5000 keywords but somewhere else in the documentation it says you should only use 3 to 4 keywords. Right now I have about 6 or 7 keyword phrases. I picked keywords that were only getting about 300 searches a day with medium to low competition. Anyway it seems all activity has stopped. No impressions, no clicks. The ad shows to be active. What is it I'm missing?
