Depending on the service, it typically takes a few months to get things dialed in to start generating good results. There is no overnight success. If you want it done right, it takes time.
Example: If I wanted to go to the gym and lose 50 pounds, there is no magic pill that will help me lose 50 pounds in a month. It takes time, hard work, and effort. If I stick with it for 3 to 6 months, I will see the results.
The same rules apply to marketing.
