Using Automated Rules
Automated rules can be great and can save you lots of time but its important to know what you are doing when you use them.
A thing to note about automated rules is that they are exactly that, automated. I have seen people run automated scripts daily, trying to stay within the top 2 Adrank. This can be a true disaster if your competitor is doing the same or you have a quality score issue.
A common script to run is trying to keep a high adrank by increasing bids automatically if the average position is consistently below a certain number. The script does not know that your profit margins are at $8 so it will happily bid $15 a click.
Ensure you set your limits with automated rules. Even if yo are reluctant, set a max CPC ceiling so its doesn’t go over board.
What you can do to fix it:
Add Quality score in your automated bid. Ensure you dont increase bids where the quality score is under 5, There are other factors you need to address and simply upping bids with your automated rules won’t solve the issue.
