Hi,
All of that information is stored in your database. Every link to a merchant's website is tracked.
Currently that information isn't exposed in your backend section but if you have access to phpMyAdmin you can run the following query (this assumes your WordPress $table_prefix is set to 'wp_').
Code:
SELECT
p.id AS ID,
p.name AS Name,
p.site_link AS Link,
stats.views AS Views,
stats.clicks AS Clicks
FROM
wp_dfr_shop_products AS p,
wp_dfr_xhits AS stats
WHERE p.id = stats.id
ORDER BY stats.clicks DESC
That will give you a list of products ordered by number of clicks descending.
