- Improved URL structure with service-specific targeting
- Implemented schema markup for Local Business and Service
2. On-Page & Semantic SEO

- Push new content with optimized and comprehensible keyword research
- Published 30+ long-form service pages and local landing pages targeting Dhaka-based areas
