Frequently asked questions

What is BSR Trend Predictor?

BSR Trend Predictor analyzes your product's Best Seller Rank history to predict future sales trends. It identifies if sales are improving, stable, or worsening.

How accurate are the predictions?

Predictions are based on historical BSR data and trend analysis. Accuracy depends on the amount of data provided (more days = higher confidence). Confidence levels are shown for each prediction.

How many BSR values do I need?

At least 2 BSR values are required, but 7+ days of data provides higher confidence predictions. Enter BSR values separated by commas, with most recent value last.

What does improving/worsening trend mean?

Improving trend means BSR is decreasing (getting better), indicating growing sales. Worsening trend means BSR is increasing (getting worse), indicating declining sales.

Can I use this for any category?

Yes, the tool works for all Amazon categories. Select your category to get accurate sales estimates based on category-specific BSR-to-sales conversions.
