Frequently Asked Questions
We pull new launch data regularly and rebuild the entire index. Historical scores are preserved. A product's launch-day numbers don't change retroactively, which keeps the rankings honest.
Because interest score measures initial attention, not quality. A 300-interest product with 0.50 engagement ratio has a small, obsessed audience. That's usually a better sign than 3,000 interest with 0.08 engagement, which screams 'great marketing, thin product.'
The index tracks launches automatically. If something's missing, it either launched below our engagement threshold or hasn't been indexed yet.
Primary target audience at launch. Some products serve both. We classify based on who the product was positioned for, not who ended up using it.
We're working on it. Right now, the index captures launch data and community metrics. Direct product links are coming in a future update.
