The structure of your ad campaign and ad group is very important. Make sure your ad group is named of which is related to the ad campaign name. First, set your daily budget to about $20.00 and then set your keyword bids to 3-5 times more than the current bid requirement. It’s better for you to only place 1-5 keywords in each ad group.
You could then reduce the bid cost of each keyword down by half once your CTR is around 5-25%. If your QS still “Great”, you should notice that your number of clicks per day is still the same even your bid cost is lower now.
The next day, reduce the bid cost down again by 10-20% of the actual price google initially wanted for that keyword. This means that if the keyword is 50 cents, reduce it to 40-45 cents but assuming your CTR is still rather high. Although you reduce your bid cost, you still get the top position while others pay the top amount to be in position 1. As you start building history with Google, you can then set bids at around 5-10 cents and still be at the top position.
