Today, I'd like to tell story about best rating feature in Envato market. Most authors doesn't know about this opportunity (someones may call it bug, or wrong algorithm).
One of our theme had pure 5.00 stars with more than 50-60 ratings, we gained that by providing superior support, and we noticed that our item traffic grow day by day. Then, someday, one of the users put 4 star (not bad), and our traffic decreased 4 times! https://screencast.com/t/4bHJ2AnsWma
I couldn't understood why only one 4 star among the rest 60 5 stars, could reduce traffic 4 times. Then I investigated the issue and found out how it works. It works in the following way - it list on top those sites which have only pure 5.00 above all others.
Let's compare two items:
quantity of ratings: 1000 with 5 star ratings, and 1 only 4 star
quantity of ratings: 50 with only 5 stars.
Logically when you filter with best rated, ItemA should come on top, because 1000 people voted 5, and only 1 voted 4.
But on Envato market sites it works vice versa. There are few themes which come on top with best rating filter on top behond other themes which is not pure 5.
Also, doesn't matter whatever you search, if ItemB has any keyword inside it's page, it will always come on top.
Hopefully Envato team will take a look at this weak side of filtering algorithm, and make corrections.
This problem exist on all market sites.
