What's up Hacker News, I built a keyword grouping tool as a developer managing my own websites' SEO, I found myself annoyed with expensive subscription based SEO tools with lots of unnecessary features for my needs. So I made a simple tool for myself that grew into it's own SaaS. Optiwing has tools for Keyword discovery, grouping, content briefing, Search Volume, Schema creation, and SERP comparison. What I did different: Pay-as-you-go pricing with no subscriptions, Simple integrated workflow from keyword research to grouping, to content briefing, Large scale keyword grouping to identify which keywords can be targeted with a single piece of content using live search data for accuracy. I'd love feedback, especially from others doing technical SEO or programmatic SEO who have used topical clustering in the past.
