We do not require long term agreements, but we do hope to provide you with the service that keeps you with our company. If you do not stay with us, we chalk that up as a failure because that means we failed to provide you with the best service and the best results. We have clients who have been with us for four years. Even though their contracts are month to month, they are happy with our services and choose to stay with us through the many changes that Google makes to its algorithm over time.
