The Attribution Gap
Website visitors call, but without dynamic number insertion, clinics can’t link inquiries to the campaigns that drove them.
The Real Attribution Challenges
01.
Marketing campaigns cannot be linked directly to calls.
02.
Calls from online and offline campaigns often create tracking gaps.
03.
Multi-location campaigns make reporting inconsistent and confusing.
04.
Insights into conversion trends are frequently lost.
05.
Manual tracking is error-prone and consumes valuable team member time.
Industry-Specific Challenges
Dental
- PPC or social media ads generate calls that are not linked to specific campaigns.
- Clinics cannot measure which ads lead to new patient conversions.
Physical Therapy
- Local campaign numbers are not displayed dynamically for callers.
- Attribution gaps prevent tracking which campaigns drive patient inquiries.
Optometry
- Seasonal promotions and exam campaigns generate calls that cannot be traced to their source.
- Leads from these campaigns often go untracked for follow-up.
Veterinary
- Boarding, grooming, or wellness campaigns create calls without source attribution.
- Revenue opportunities from these campaigns are frequently missed.
The Outcome Without dynamic number insertion, clinics lose visibility into which campaigns drive calls, miss follow-ups, and cannot optimize marketing spend for patient growth.
