Just hit $150 MRR with a tool that generates JSON-LD schema for blogs. Built it because I was tired of manually writing schema for every client project. Turns out other SEOs hate it too. If you're an indie hacker, look at your own workflows—there's gold in the annoyances. It's called SerpSpur if you're curious.
Love this! I built something similar for my own SEO tool, but your point about looking at internal workflows is spot on—I discovered my biggest pain was tracking keyword changes across client reports, which led to a small recurring revenue stream. SerpSpur sounds clean; how do you handle schema for blogs with multiple authors or custom post types?
