Tips for writing best reviews

Share Your Voice

DriversAutoKnow.com is intentionally an inclusive review site, especially for those who are under-acknowledged. All voices matter in assisting and empowering others to make smart decisions on where to get their vehicle service.

Be Genuine

Honesty is the best policy. Be authentic and polite in describing what worked, or perhaps, what didn’t. No coarse language.

Be Specific

“Joe is great” doesn’t provide detail to the experience. What was your visit like? What happened? Mention the name of the individual who helped you, of course. How did they assist? What was the interaction like?

Stay on Point

Reviews only need to be a few sentences. There is no need to exaggerate or get too lengthy. Less is more.

Be Thoughtful

Give it a once over for context and content. You can always edit your review. Proofreading is a good idea.

Be Respectful

We all want to be treated with respect. You are encouraged to share your experience in a courteous manner. No coarse language.
