I built a PDF viewer and all I'm getting is bots

I've been building Fracto.dev for a few months — a PDF viewer that lets you read distant pages side by side.

The product works. Stripe payments are set up.

But when I check Google Analytics, most sessions are 3–6 seconds.

Bots, probably.

I've tried X (0 followers), Product Hunt (no reaction), Reddit (removed by filters),dev.to, note.com (medium.com of japan), Zenn(tech blog service in japan).
