The Two-Sided Problem
A marketplace or staffing business has two audiences that both need to be reached through advertising: the buyers of the service and the providers of the service.
For a home health care company, that means families looking for care for a loved one AND caregivers looking for work.
Both audiences search Google. Both searches contain overlapping vocabulary — ‘home care’, ‘caregiver’, ‘senior care’.
Both need to reach the same company. But the message for each is completely different, the landing pages are different, and the conversion action is different.
Running both in a single campaign produces ad copy that speaks to neither audience well. Running them in separate campaigns — with strict keyword separation between them — reaches both correctly.
Same company. Two audiences. Two campaigns. Zero overlap between them.
The Campaign Structure
Campaign 1: Client acquisition
Keywords targeting families seeking care: home care for elderly parent, senior care near me, in-home caregiver services, respite care, memory care services at home. Ad copy speaks to the family: peace of mind, qualified caregivers, personalized care plans.
Exclusions: job-seeking vocabulary — careers, apply now, caregiver jobs, work from home, job openings. Every search from a caregiver looking for work is blocked from the client campaign.
Campaign 2: Caregiver recruitment
Keywords targeting caregivers seeking work: caregiver jobs near me, home health aide jobs, CNA jobs, caregiver positions, senior care jobs. Ad copy speaks to the caregiver: flexible hours, competitive pay, meaningful work, good employer.
Exclusions: client-seeking vocabulary — care for my parent, senior care services, find a caregiver, home care agency. Every search from a family seeking care is blocked from the caregiver campaign.
The Conversion Actions
The two campaigns have different conversion goals. Client campaign: contact form submission, phone call, free care assessment request. Caregiver campaign: job application submission, recruiter call, information request.
Tracking both separately gives Smart Bidding two independent optimization targets. It learns which searches produce client inquiries for campaign 1 and which produce caregiver applications for campaign 2 — without the two signals interfering with each other.
The Budget Allocation
Most marketplace businesses have an imbalance — they either need more clients or more caregivers at a given time.
The two-campaign structure allows budget to shift between sides based on current business need. When caregiver supply is short, increase caregiver recruitment budget. When client pipeline is thin, shift budget to client acquisition.
A single campaign can’t do this. It optimizes toward whichever conversion type Google finds easiest, regardless of what the business actually needs.
Where This Applies Beyond Home Health Care
The dual-side structure applies to any marketplace or matching business: staffing agencies (clients and candidates), real estate (buyers and sellers), tutoring (students and tutors), event staffing (venues and staff).
Any business that needs to attract two distinct audiences to make the business work.
The principle is always the same: strict keyword separation, separate conversion tracking, independent budget control. The audiences share vocabulary but not intent — and the campaign structure needs to reflect that.
