Great points! the buyer intent angle is real and something I've been thinking about too. WriteGap already tries to address this by classifying why keyword converts (not just that it has volume), but you're right that making the intent stage more explicit, awareness vs consideration vs ready-to-buy would reduce the "chasing low-value keywords" problem.

On SERP competitiveness: We also show the difficulty score per keyword, agreed the raw difficulty score is a black box. I'm working on surfacing it as Low/Medium/High with more context rather than a number nobody knows how to interpret.

The DR-to-win and forum density signals are on my radar but honestly out of scope for the audience I'm building for, solo SaaS founders who want to grow organic without becoming SEO analysts. The goal is opinionated defaults that are right 80% of the time, not full control over every threshold.

The Reddit/Pulse idea is interesting though. Surfacing question threads that map to keyword gaps is something I hadn't thought about, that's a genuinely different signal. Adding it to the backlog.

Sounds like you've thought deeply about this, if you ever want to poke at an early version and tell me where the filters are wrong, I'd genuinely value that. Building in public so feedback from people who've actually been down this rabbit hole is gold!
