🚀 How I Built Calcuzy.app in 4 Hours (and Got 120+ Visitors in 48 Hours)

So a random idea clicked.
Not a big startup. Not a serious product.
Just a fun weekend build to learn SEO, ads, traffic, and how fast things can move on the internet.

I built Calcuzy.app — a super-simple “all tools in one place” website.
No big dreams. No virality expectations.
Just curiosity. 🤷‍♂️

But here’s the crazy part…

⚡ It got 120+ visitors within 48 hours — without posting anywhere except Reddit.

And it's not even something unique 😂
(There are like 1000 other “tool websites”. Trust me, I’m not pretending it’s special.)

But this experiment taught me something important:

🧠 Good SEO + clean performance + correct metadata = instant real traffic.

Here’s how I did it:

🛠️ The Stack (kept it super basic)

Next.js 14 (static export)

TailwindCSS

Zero backend

Google AdSense (testing phase)

SEO-first structure

Manual metadata for every page

100/100 PageSpeed on most runs (both mobile + desktop)

🔍 What I actually learned

This was the real point of the project:

✔ How SEO really works

Title tags, descriptions, JSON-LD, internal linking…
The basics matter more than fancy algorithms.

✔ How Google AdSense works

Still waiting for approval 👀 but learned:

placement matters

CLS matters

speed matters

compliance pages matter A LOT

✔ How fast small projects can attract real users

Google indexed it in hours.
Traffic came the same day.

That felt wild.

📊 Some Analytics Snapshots

(Feel free to show the screenshots you posted earlier.)

120+ visitors, purely organic.
No social posting.
No marketing.
Just SEO doing its job silently.

🤏 It's not a big project. But it taught me big things.

Most devs think:

“Small projects don’t matter.”

But honestly, building small things teaches you more than thinking about big things.

This wasn’t a startup.
This wasn’t an invention.
This wasn’t meant to “change the world”.

It was just a fun idea → shipped fast → learned a lot.

Just ship.
Even tiny projects can bring big learnings.
