🐶 PuppyGrowthCalculator.com — The Viral Niche Tool You Can Clone in a Weekend

“It got 2.6 million visits out of nowhere — from one simple tool. And anyone can build this.”

🧠 What Is It?

PuppyGrowthCalculator.com is a hyper-niche, ultra-simple website that lets users estimate how big their puppy will grow.

That’s it.

No blog. No store. No social media. Just a single-page calculator that blew up from 1 visit/month to 2.6 million in March 2025.

And yes — you can build this exact site using free tools, your own domain, and a basic site builder.

📈 Traffic Breakdown (Why This Deserves Your Attention)

This site did nothing for over a year — and then exploded. Most likely via organic virality on Reddit, TikTok, Facebook parenting groups, or newsletters.

🛠️ How the Site Works

• One-page calculator (likely JavaScript-based)
• You enter your puppy’s breed, age, and weight
• It estimates final adult weight based on basic growth models

That’s it. No deep tech required. The value is in niche specificity and utility.
