For three mornings in a row, my audit log printed the same line: published today: 0 / target: 3. Nothing crashed. The scripts ran, exited, and produced nothing. The entire cause turned out to be a 41-second margin — a 300-second timeout against a process that actually takes 259 seconds. Changing one number to 600 turned 0/3 into 3/3 the next morning.
Some background: I went from earning 100k yen a month as a university student to 600k a month juggling multiple gigs, then lost all of it overnight to a company-initiated layoff. Over the following six months I built an autonomous Claude Code environment, and I'm now above 1.2M yen in monthly revenue. At the core of it is a system that publishes three affiliate articles every morning without a human touching anything.
Why this system works
The difference between people who keep earning from affiliate marketing and people who drop out is not writing skill, and not a nose for picking products. It's whether you can keep going.
Articles that tend to earn on Rakuten Affiliate share a common pattern: spec-comparison articles about home appliances and gadgets priced above 50,000 yen, with lots of reviews and in stock. Robot vacuums, portable power stations, heat-pump washer-dryers, fully automatic coffee makers. The search intent is "I want to compare before I buy," so product link click-through is high and it fits the structure of affiliate marketing well.
