What's up Hacker News, I built a keyword grouping tool as a developer managing my own websites' SEO, I found myself frustrated with expensive subscription based SEO tools that had lots of unnecessary features for my needs. So I made a simple tool for myself that grew into it's own product. Optiwing has tools for Keyword discovery, grouping, content briefing, SERP checking 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 Google search data for accuracy. I'd love feedback, especially from others managing their own SEO who find existing tools too expensive for their needs. Cheers
