Optimization playbook

  1. Kill waste: negative keywords from search terms
  2. Improve RSA assets: pin sparingly; test benefits vs features
  3. Fix landing message match and mobile speed
  4. Shift budget to ad groups with acceptable CPA
  5. Re-test bids/audiences only after tracking is clean

Case study: Weekly optimization for a Chitwan hospital OPD campaign

Week 1 data: CTR healthy (6%), CPA high because many clicks were “nursing vacancy” and “salary.”
Actions: Add job negatives; rewrite ads to “Book OPD appointment”; landing CTA = call + WhatsApp; mark both as GA4 key events.
Week 3 pattern: CPC slightly higher, CPA down because clicks were patients, not job seekers.

Second insight: Saturdays converted; late-night clicks did not (no staff). Ad schedule trimmed → better CPA without creative changes.

Nepal practice: Optimize to qualified inquiries (appointment booked), not form fills from competitors researching you. Align marketing and front-desk definitions of a lead.
