Even fewer know this trick. It's possible to sort an Amazon search by total number of reviews, instead of just the average review.

Here's how to do it:

1. Search for something on Amazon.
2. Select a department that matches what you're looking for.
3. Sort the results by average customer review.
4. In the URL, replace: 'review-rank' with 'review-count-rank'.

For example, change:

https://www.amazon.com/s?k=mouse&i=computers&s=review-rank

to:

https://www.amazon.com/s?k=mouse&i=computers&s=review-count-rank

Your results should now be sorted by the total number of reviews, which I find has much greater signal than the average review.

If this didn't work, you probably didn't select a department. Sometimes it doesn't show up in search results, so you might have to try different search terms.
