If you want to boost your listing’s BSR, you need to increase sales.
To do this you should sell a consistently high-quality product and keep it in stock at all times. Running out of stock will send sales to zero and put a big gap in your sales history. Product reviews are also a big factor in building consumer trust and improving sale conversions.
Price is an important search ranking factor on Amazon. Products priced competitively appear higher in search results. To keep sales coming in, your products should always be well priced compared to competitors selling similar products. Many sellers use automated repricing software to do this.

Product promotions can also help to boost sales and therefore your BSR. You can often see this at work, where a product on promotion in a specific category will start to climb the best sellers chart.
This camelcamelcamel.com chart shows a steep BSR climb for a product with regular price drops in the last 2 months.
However, some FBA sellers have reported that when they offered a product at a discount their BSR did not increase at the rate they expected. Amazon’s algorithm may be taking promotional giveaways into consideration, and scaling down the impact on BSR when it is due to aggressive discounting.
