After everything is setup and running possibly the most important step is reviewing all keywords every 2 weeks to a month to see how things are going and make potential corrections. In this step it is important to have a quality ad tracker to ensure reliable data in order to make educated decisions.

The frequency of checking your ad tracker depends on how many clicks are being made, the more clicks and conversions that are recorded the more reliable the information. It is important to not make immediate decisions but to wait until you have sufficient information. A bad example would be after your first conversion comes through to assume that the keyword that generated the actual sale is the only good keyword when in reality it could have been luck. Make sure you have enough data to make an educated decision.
