Complete Guide to Organic and Paid Search Marketing – By SickDevs NG
Understanding SEO and SEM

| Cost Structure | Time investment, potential service fees | Pay-per-click (PPC) model |
| Time to Results | 3-12 months for full impact | Immediate visibility |
| Traffic Quality | Higher trust, better conversions | Varies by targeting precision |
| Longevity | Sustained results over time | Only while campaigns are active |
| Click-Through Rates | Lower but more qualified | Higher but less targeted |
| Maintenance | Continuous optimization | Daily budget management |
