Currently you can sort by popularity, which is nice, but has some flaws. It uses customer review count to sort, so items with many very low scores can place high on the sort. Also old items that have acquired many reviews over time, but are currently outdated or old tech, can place high on the sort.

I suggest you add a "Sort by What's Hot" feature. This would sort items by most sales or maybe most views over a given time frame, like the last 30 days. This would give people a better idea of what the truly in demand products are.
