Two entirely different demand curves run through a staffing agency's website, and confusing them is the classic failure. Job seekers generate the overwhelming majority of search volume, arriving on shift and role queries at all hours, mostly from phones. Employers generate far fewer searches but each one is worth an order of magnitude more, and they search in a completely different register: agency, contract, temp-to-hire, industry and city. An agency that celebrates traffic growth without separating the two is usually just celebrating applicant volume it already had.
Employer demand is triggered by a production event. A contract lands, a line runs a second shift, a peak season starts, or three people quit in a week. When it hits, the buyer is under real operational pressure and calls whoever appears credible fastest, which makes response speed part of the marketing rather than a sales detail. They want to know fill times, whether you actually staff their role type, how markup works, and what happens if a placement does not last the week.
Seasonality is sharper here than in most professional services. Warehouse and logistics demand builds hard into peak retail months, manufacturing follows its own contract cycles, and administrative hiring lifts at the start of budget years. Candidate supply moves opposite to that in the tightest periods, so the campaign has to flex: pushing employer acquisition when candidate supply is comfortable, and pushing recruitment when a contract is signed and the roles are unfilled.
