When people search for “best side-hustle blog ideas,” the advice is always the same:
- Start a niche site
- Write what you love
- Pick a profitable category
- Be consistent
…and yet the most common struggles remain unchanged:
- You run out of topics
- Competitors are too strong
- You don’t know what to write
- You lose motivation after a few months
But here’s what almost nobody realizes:
There is a massive, evergreen, low-competition niche hiding in plain sight.
Introducing…
The “Error Blog.”
Wait—can you seriously build a blog around errors?
Yes.
And not only is it possible, it’s one of the most reliable, sustainable blogging models out there.
Think about how often these happen:
- Phone won’t charge
- PC suddenly freezes
- WordPress shows a fatal error
- GAS throws
DEADLINE_EXCEEDED - A login button stops responding
- Chrome keeps crashing
- A smartphone app won’t open
- Android notifications don’t arrive
- Twitter/X refuses to load
- API calls randomly fail
Every one of these errors is a search query.
Every day.
By millions of people.
This niche literally regenerates itself because technology constantly breaks.
Why Most People Fail at Side-Hustle Blogging
Because they choose categories such as:
- Beauty
- Finance
- Diet
- Gadgets
- Travel
These niches have insane competition, require deep expertise, and demand constant content updates.
But an error blog?
It plays by completely different rules.
5 Reasons the Error Blog Niche Is Overpowered
1. Infinite content. Your life itself becomes the topic factory.
Use your phone → a bug appears → article.
Try a new app → weird behavior → article.
Update software → something breaks → article.
You no longer “search for topics.”
Topics find you.
This is the closest thing to a “perpetual blog machine.”
2. Error reports are first-hand experience → Google LOVES this
Google rewards:
- originality
- real screenshots
- personal debugging steps
Error content is almost always EEAT-friendly because it comes from your real environment.
3. Competition is weak—especially for micro-errors
Examples:
- “GAS internal error fix”
- “Android notification not showing 2025”
- “Chrome blank page solution”
- “WordPress button doesn’t respond”
- “X Android can’t retrieve posts”
Most people never write about these.
Big media doesn’t bother with small issues.
→ Perfect blue ocean.
4. Translate articles into English → traffic doubles
Most error keywords are GLOBAL:
- WordPress
- GA4
- VS Code
- Android
- Google Apps Script
- API errors
Publish JP + EN versions?
Boom. Your potential market just doubled.
5. Readers are in “urgent mode,” which boosts SEO
People searching for errors truly need help now.
This means:
- Higher click-through rate
- Longer time on page
- Lower bounce rate
Google LOVES these signals.
If you’re stuck choosing a side-hustle blog niche…
Error Blogging is actually one of the most practical choices.**
It’s:
- beginner-friendly
- endlessly renewable
- easy to differentiate
- globally scalable
- ads/affiliate-friendly
- sustainable long-term
And you don’t need to be a programmer.
Even everyday smartphone hiccups can become great posts.
