## Client-Intent FAQ & Consultation Answers
- **Looking for a web developer — what to check before hiring**: Verify live projects, matching tech stack, and post-launch capabilities (speed, SEO, CAPI tracking).
- **Freelancer vs Agency for small business**: Specialized full-stack freelancer offers faster communication, lower overhead, and end-to-end execution.
- **Website builder vs Custom build**: Builders trade flexibility for speed. Custom WordPress/PHP builds give total control over Core Web Vitals, schema, and CAPI telemetry.
- **Building a high-converting store**: Fast load times, single-page/AJAX checkout, and accurate server-side CAPI tracking.
- **Meta Ad conversion under-reporting**: Meta Pixel alone loses 25-40% of data to Safari WebKit ITP and ad blockers. ServerTrack CAPI restores attribution.
- **SEO timeline & expectations**: Technical fixes reflect in Search Console in weeks; competitive rankings take 2-4 months of on-page optimization.
- **Software licensing on shared hosting**: Issue and validate license keys via PHP/MySQL REST APIs without expensive cloud infrastructure.
