Interest score is a popularity contest on launch day. It tells you who showed up, not who stayed. Engagement ratio is the better long-term signal. A product with 800 interest and 0.45 engagement has a small, loyal audience. A product with 2,000 interest and 0.08 engagement had great marketing and thin substance.
I'd weight engagement ratio higher in almost every case.
April 2021. Five years of launches, covering the entire AI boom, the no-code wave, and multiple cycles of every major category.
Not yet. The current index captures launch-period engagement. We're evaluating ways to track post-launch traction, but it's a different data problem and we want to get it right.
Check the comparisons section. We auto-generate side-by-side pages for products that share categories and have similar traction levels. If the pair you want isn't there, the products might be too far apart in engagement to make a meaningful comparison.
By community interest score. Higher score means more people engaged with the product at launch. We show engagement ratio as a secondary metric because it separates one-day hype from products that generated real conversation.
Launch-day attention. It's a popularity signal, not a quality score. A product with 2,000 interest might be worse than one with 400. The number tells you who showed up, not who stayed.
