One of the ways on how to rate products is customer satisfaction ranking. Envato Market does offer such solution allowing everyone who purchased products via their marketplace rate them. In addition customers are able to provide their reasonable comments in order to explain their given rate and decision.
From perspective of customers such ranking system allows easily track successful and beloved products and of course be aware of low rated ones which may inform them about poor quality, support or some other product related issues. Once you will see popular product with high ranking you can be sure that this is a high quality product you may look into and if you find out that it does exactly what you need this is a win situation.
On other side of the table there are product owners who must care about their product ranks and be smart enough to use them as a feedback mechanism. Any time product owner receives low ranking it is mandatory to carefully study reasons and act accordingly in order to be sure this won’t happen again. Instead many product owners get angry about someone not to pay “well deserved” respect to their products. Make, receive feedback, improve and repeat – this is a well known mechanism of success which every company and individual should follow.
If we take a look at WPBakery Page Builder as an example – during those years we always track rankings and analyze comments we receive in order to discover bottlenecks within our software and align our future strategy with our custom feature requests. Such approach involves our customers into the process of development and idea generation and ensures that we deliver exactly the same things they are asking for at the right place and time.
Our strategy helped us significantly improve our rankings within relatively short period of time. Thanks to this approach we are 100% sure that our deliverables are meeting our customer expectations in the shortest possible time frame.
