In my humble opinion, the issue with reviews is the most significant challenge facing authors on TES. Some of my FREE resources have been downloaded 1000s of times and not a single review has been left. The solution is pretty obvious: incentivise reviews for premium resources. "Get 10% of your purchase back [AS TES >CREDIT<] if you leave an accurate and helpful review for your purchase" One or two less "25% OFF SALES "(as much as I love them) would cover the costs. At the moment, reviews are worth their weight in gold, and customers have very little way of discerning "I've spent 4 hours making this" lessons from "I made this during registration whilst drinking coffee" resources. Any other suggestions for how we can systematically improve the review system?
