Talk about your experience specifically and objectively. "The doctor was able to diagnose the exact problem in the very first visit after six months of bad experiences with other doctors" is a good description of your experience. "This doctor is a genius at diagnosing his patients" is not. Describe your own experience. Don't try to generalize about other patients.
Write long reviews but keep the content to the point. Other people reading your review do not need to know what your test results are but want to know your conclusion. The longer and more focused the review, the more likely it will help others.
Describe what you have experienced at the doctor’s clinic and how your overall experience with the diagnosis & treatment was. Try to inform people of what they might expect when they visit the doctor.
Be authentic. Analyze your own experience, and explain why you liked or disliked your experience with the doctor. Your review will help many people in choosing the doctor for their treatments. Honesty is still the best policy!
Not every experience with a doctor is going to be perfect. Sometimes you’ll want to share negative feedback. Even if you’re frustrated, make sure your criticism is constructive. Do not make remarks about race, color, religion, handicap, national origin, marital status, or parental status. Avoid foul language because you are getting the lime light here and you don’t want to be seen a bad light by other readers.
When writing a review for the doctor, write down your practical experiences and do not tend to get emotional about the doctor. Remember, your review will be a decision making point for someone else.
You can write about the reason for your visit, whether you had to wait very long to see the doctor, doctor's behavior with you, whether the doctor listened to your problems fully, whether the doctor provided enough information about the problem/treatment, were you happy with the treatment and got cured, would you recommend the doctor to others, etc.
Do not forget to conclude your review by stating your overall experience and whether you recommend the doctor to others or not.
Don’t put image links or other irrelevant links in your review. Don’t put your contact information. Do not use abbreviations or Twitter/SMS-like language.
