Amazon has made a big effort to build a sales ranking mechanism. You can find sample references on the website, as they include all sales ranking statistics, weekly or monthly sales amounts, and product overview charts and information.
You can track your sales through Amazon sales estimator from https://www.turbopiranha.com/amazon-estimated-monthly-sales/ for your business. The website is structured so that you can make comparisons and compare the information that you record.
In addition to tracking Amazon's sales ranking for your product, I am very happy to track the number of other titles from my competitors to see how well I do in the context of my small niche.
It is very helpful to know exactly how everyone is doing because I can see where I have problems and where I've made mistakes. Because sales ranking information is recorded every hour to determine the impact of each ad or article that the publisher publishes in real-time.
Sooner or later, all publishers may have to get this service to look forward to my weekly updates to speed up the journey to the Amazon world – the competitive analysis for marketers, publishers, and advertisers.
It is a good idea of what's on the right track by tracking Amazon's Sales Ranking and Amazon's Sales Estimation.
