SEO and Google Ads can both help recruitment agencies win employer clients, but they solve different timing problems. The useful comparison is not “free clicks versus paid clicks”; it is how each channel contributes to qualified hiring conversations.
Use Google Ads when speed and control matter
Paid search can test recruitment-service demand quickly, target specific sectors or locations and send traffic to a tightly matched employer landing page. It is especially useful when you need evidence before investing heavily in a wider content programme.
Use SEO to build durable demand capture
SEO is better suited to building a library of strong sector, role and service pages that can attract employer demand repeatedly. It also supports trust when decision-makers research an agency before making contact.
Do not blend candidate and employer performance
Candidate job searches can create large traffic numbers that hide weak client acquisition. Report employer enquiries and qualified vacancies separately from applications.
Compare cost per commercial outcome
For Google Ads, trace spend to qualified employer opportunities. For SEO, include the cost of content, technical work and ongoing optimisation, then compare the opportunities and revenue those pages influence. CPC versus SEO retainer is not a like-for-like commercial comparison.
Often the best answer is both
Paid search can validate language, offers and landing pages while SEO builds longer-term visibility. Use shared conversion tracking so both channels are judged against the same business outcomes.
