From GitHub Pages to Custom Domain: Complete Guide to Porkbun, Cloudflare DNS, AdSense Approval, and Multi-Engine SEO
Hosting a developer blog on GitHub Pages under username.github.io/project is one of the quickest ways to share technical insights. However, as your readership grows and you prepare for professional monetization, you hit a hard architectural wall: Google AdSense strictly prohibits free subdomains like *.github.io. To qualify for AdSense publisher verification, establish domain equity, and secure multi-region organic reach, you need your own apex custom domain.
Migrating a static documentation or engineering site to a custom domain is not just a DNS record change. It involves coordinating registrar name delegation, edge SSL termination, canonical redirects, automated publisher ads.txt hosting, and navigating subtle search console UI quirks across global and regional search engines.
In this guide, we break down our end-to-end migration from jbjihwan.github.io/global_blog to https://globaldevlog.com, including our zero-downtime DNS architecture, AdSense integration, and actionable solutions for real-world indexing traps in Google Search Console, Naver Search Advisor, and Bing Webmaster Tools.
