6. Deploy your new plan
After you have come up with your new hypothesis with the relevant tweaks made to the plan. You can deploy it once again. Keep monitoring the results to see if it yields the kind of traffic or sales you desired in return. You can keep make changes to the plan till you think it works well enough for your current goals.
No plan is permanent hence it can and should be changed at all times. This means you need to keep reviewing everything so that you can keep making it better and getting better results!
