I was paid $27,399 in affiliate commissions in May, as reported here: https://ebizfacts.com/finance-reports/may-2021/
That surpassed my previous high of $21,641 last December and up from $17,713 in April.
I started into affiliate marketing back in 2018 and this has been my progress...

As you can see, income is trending upwards in general but it's a bit unpredictable from one month to the next. This is mainly due to some affiliates paying on an irregular schedule.
Including other sources of income, my business earned $27,683 in May, which is the most it has ever earned in a single month.
Expenses were $5,106. Which leaves a profit of $22,577 for the month, also a new high 🥳
