It only depends on what your turnaround is and your ROI is per client. This will not help to promote your business as much as it will help customers leave a review. Which if you are diligent you can ask for in person.
It's totally NOT worth it! Take a quick read through all the negative comments for yourself. It did nothing for my business, and they would not let us cancel, telling me that I'd still have to pay for half of the entire year's subscription.
