I have written about this before but it is worth restating. If you are writing your first review my advice is make it BALANCED. That means write the best bits about about the meet; "she met the dress request," "she swallowed as advertised," AND the worst bits, "she can't deepthroat though she advertises it," "she is a dress size bigger than the profile states."
If you include an accurate evaluation of both the strengths AND the weaknesses of a WG's performance it will lend credibility to your review and help others decide if they want to see her; check out my review on Sensual Brigit (great girl, heartily recommended, definitely NOT for everyone).
Pimps and touts can't do this convincingly because their purpose is to persuade.
There are lots of reviews, and reviewers, I ignore. Lack of balance and a persuasive tone are clear warning signs that a review cannot be taken at face value in my opinion.
