How to generate new, meaningful ideas?

- Speak to real human customers
- Gather real humans from different parts of biz
- Outline clear opportunity, based on what real humans are trying to get done

Ban any "use AI" easy cop out ideas.

“Most CRO test screenshots are bullshit” 🎯

@andrewjfaris great pod w/ Mars Men head of ecom

He lists the most common issues, but this quote nails it:

“Doing CRO is easy, doing CRO the right way is hard”

@Tudi_rad Our house was stacked with boxes of wine for my ecom business 15 years ago. (We drank much of the stock)

@jforjacob How long it takes until the lines “level out” is itself a random variable, not a property of the site.

No need to invent weak heuristics. Simply use a statistical power calculator before running the test.

@johnhickey1970 What did they get wrong?

@codyplof grok ftw

[Johann Van Tonder @chat_JVT]

@codyplof You should write more long form. This may be the best overview on the topic I’ve ever read.

From someone who’s gone super deep in this rabbit hole over 15 years and read / studied everything worth laying eyes on.

[Johann Van Tonder @chat_JVT]

@jforjacob Big factor for sure, but even sites with no reviews (yup they exist) see wild swings in CVR day to day.

Sol Medium -> sweet spot intelligence vs cost per task

Fable -> if you want absolute highest intelligence, cost secondary

Sol High -> near-top intelligence at far better value

Sonnet 5 -> meh

Opus 4.8 -> overpriced vs Kimi K3, basically an expensive Sol High 👇

On sheer intelligence:

@DaveDiederen Yup downgraded Claude to $20

Codex is 🔥 even for knowledge work,

and with some guidance I find GPT a much better writer than Claude

@petergyang It’s hard to find something here that is NOT ai-written

“only 53.2% of X articles flagging as fully human-authored”

@codyplof It’s actually standard practice for reputable CRO agencies.

In fact, quantifying $ saved from preventing loss-making changes permanent only supports the case for CRO.
