Sleep Calculator
Sleep well keep fresh
A few months ago I was frustrated.
I kept waking up exhausted — even after sleeping 8 hours. I'd set
my alarm, do everything "right", and still feel like I'd been hit
by a bus.
Then I learned about sleep cycles. Turns out it's not how long you
sleep — it's WHEN you wake up within your cycle. Wake mid-cycle =
groggy. Wake at the end = refreshed.
So I built a calculator to solve this for myself.
Then I put it online. Then people started using it.
SmartSleepCalc.com now has tools for:
→ Bedtime calculator
→ Wake-up time calculator
→ Nap calculator
→ Shift work sleep optimizer
→ Epworth Sleepiness Scale test
All free. No login. No fluff.
The SEO strategy that worked:
- Target long-tail "calculator" keywords with zero paid competition
- Each tool = its own dedicated page
- Simple, fast, mobile-first design
- Structured data (schema markup) on every page
Traffic is growing month over month purely from organic search.
Here's what I'm still figuring out:
- Best monetization mix (AdSense vs affiliate vs SaaS)
- Building an email list from tool users
- Expanding to multilingual pages
Happy to answer questions about the build, the SEO approach,
or anything else. What would you do differently?
