Made My First $100 Solving an SEO Problem I Personally Hated

A few months ago, I was doing SEO work for clients and kept running into the same annoying task over and over again: writing JSON-LD schema manually.

Every site needed different markup:

Articles
FAQs
Products
LocalBusiness
HowTo pages

And every time, I’d end up digging through schema.org docs, validating nested properties, fixing commas, then testing everything in Google’s Rich Results tool.

It felt ridiculously repetitive.

So one weekend I built a small AI-powered schema generator for myself. You paste in a page URL or describe the content, and it generates clean JSON-LD automatically.

At first it was just an internal tool.

Then I shared it in a few SEO communities.

This week it made its first $100.

Not life-changing money, but honestly it validated something important:

The best product ideas usually come from problems you already deal with every day.

A lot of indie hackers try to invent futuristic ideas, but there’s real opportunity in boring workflow pain.

Especially in SEO where so much work is still manual.

A few things I learned building it:

SEOs care more about saving time than fancy AI branding
Validation matters more than generation
People want outputs they can paste directly into production
Simple niche tools convert surprisingly well if they solve one painful problem clearly

The tool is called SERPSpur:

Curious if anyone else here has built products from their own repetitive workflows instead of chasing trends.
