Gusto runs payroll, benefits, and HR for more than 500,000 businesses and works with over 14,000 accounting firms. The product covers unlimited payroll runs with automatic tax filing, medical and dental and vision plans, time tracking and PTO, workers’ comp, compliance reminders, and direct access to certified HR staff. That breadth matters because it gives you several different entry points into the same payout.

Traffic has to be US-based to be worth anything here, and the buyer is a business owner, CEO, or HR lead rather than a solo creator. Affiliates get conversion-optimised landing pages, banner sets, a dedicated affiliate team, and periodic bonus incentives on top of the base $200.

Catching Businesses at the Hiring Moment

The 120-day window is the standout number. Payroll decisions crawl through comparison, demos, and internal sign-off, and a four-month cookie covers that entire cycle instead of expiring halfway through it.

Best-converting content sits around first hires, switching payroll providers, and contractor-to-employee conversions. Accountants and bookkeepers with client bases are the strongest partners of all, since a single recommendation moves multiple businesses at once.
