Posted a data analysis on Reddit today.
Since then:

The founder of the company I analyzed showed up asking for data
Strangers dropping their extensions for free lookups

So I'm testing something: 20 founding member spots for the database behind it.
Not launching. Deciding whether to build.

Today I posted a public teardown of how a title change moved Mailmeteor's CWS rankings.
Braced myself for an angry email from their team.
Instead, the founder @frenchcooc showed up in the comments — asking if my dataset has keyword volume too.
"Helpful for companies like us."
Building in public is weird. In the best way.

Report an error

The custom date range in Datafast is not working.

Can you fix it? @marclou

[Joseph Hu @KeepGoingJoe]

@HowlingNitin lol. Thx for the info.🤣

Spent $5 for #1 in the SEO category on https://t.co/6yd0aiGRY1

Late to the party? Maybe..

But for me, now might actually be the best time to jump in.

$5 for a DR 46 backlink, a full day of SEO category exposure, and potentially a few visits.

Pretty good deal.

[Joseph Hu @KeepGoingJoe]

I don't get it.

Why did they pay so easily?

[Joseph Hu @KeepGoingJoe]

@nhrdev Cool, I'll think about it

[Joseph Hu @KeepGoingJoe]

Go for a hike.🚶‍♂️‍➡️

@BansalRahul14 Btw, it's from India

0 to 30k users in less 30 days.

A website design extractor extension

crazy

@BansalRahul14 The testimonials cited on the landing page are all from Instagram.

I think he contacted some KOLs.

56 → 5,000+ users in 9 weeks.

But the interesting part isn't just the growth.

Extension Ranker found keyword opportunities the extension wasn't targeting well.

The developer rewrited the listing based on those recommendations.

Then:
- 9/9 tracked keywords improved
- “mobile simulator”: #8 → #3
- “mobile view”: #10 → #2

This is the full case study of how the listing changed and how the rankings moved afterward ↓

@marclou You're the winner!

[Joseph Hu @KeepGoingJoe]

@KambliVedant Totally agreed.

Success comes with conditions.

No one's going to advertise for a nobody.

[Joseph Hu @KeepGoingJoe]

@KambliVedant Yeah, I think so

[Joseph Hu @KeepGoingJoe]

I don't get it.

Why did they pay so easily?

Okay let me summarize the past 24 hours for you 🤯

- launched https://t.co/ZElVA2hguv at 11:08PM yesterday
- got 200k+ visitors so far
- made $21.499 from it
- got 1500+ new followers
- broke my analytics provider
- got offered $100k to sell outbid
- 3 copycats launched already

[Joseph Hu @KeepGoingJoe]

@jonathan_wilke OK, It's pocket change for them.

Btw, I'm one of Supastarter users, and I like it.

[Joseph Hu @KeepGoingJoe]

Chrome Web Store has started limiting the number of extensions a developer account can publish.

For new accounts, the current limit is only 2 extensions. If you want to publish more, you’ll need to apply for an increase.

This is becoming harder for extension factories.

But I think there could also be new opportunities.

Has this change affected you?

[Joseph Hu @KeepGoingJoe]

@alexabelonix Couldn't agree more
I lose sleep this every night

[Joseph Hu @KeepGoingJoe]

If your extension can't get 1,000 users, but your competitors can

You should stop and think about why

[Joseph Hu @KeepGoingJoe]

The next tech giant might be hiding in the Chrome Web Store 🤪
