Building a Hugo Blog - From Start to SEO

Thu, 03 Sep 2026 00:00:00 +0000

Overview

This blog itself was built in this exact order. From the pipeline of writing in Notion, converting to Markdown, building with Hugo, and deploying to GitHub Pages, to connecting a custom domain, adding multilingual support, and applying security headers — here’s the order.

Why This Combination

A static site doesn’t need its own server to run, and hosting it for free on something like GitHub Pages already makes it fast and stable. The catch is that “static” tends to make the writing experience inconvenient — using Notion as a CMS solves that: you write in the editor you’re already used to, and an API pulls the Notion page straight into Markdown for the build. Hugo was chosen because, among static site generators, it builds fast and has a solid theme ecosystem.

4 Security Headers Flagged by an SEO Audit — Applying Them on Cloudflare Without Code

Sun, 30 Aug 2026 01:25:00 +0000

Overview

SEO audit reports sometimes flag four security headers: Strict-Transport-Security, Content-Security-Policy, X-Content-Type-Options, and Referrer-Policy.

At first glance it’s odd to see these under “SEO.” Short answer up front: these headers don’t directly boost your search ranking.

This post covers why security headers show up in SEO audits, what each header actually does, and how to apply them on a static blog sitting behind Cloudflare in a combination that’s easy to maintain later.

Adding Multilingual Support to a Hugo Site

Goal

Apply multilingual support and SEO optimization to a Hugo blog to maximize search engine exposure and provide the appropriate language version to multilingual users.

SEO Configuration

SEO (Search Engine Optimization) is the work of optimizing a site’s structure and metadata so that search engines like Google can better understand the site’s content and surface it in search results.

Building a Blog with Hugo + GitHub

Tue, 10 Feb 2026 08:46:00 +0000

Introduction

I had been keeping technical notes in Evernote and personal documents, and was preparing to run a blog using Notion’s website feature.

However, Notion had limitations on customization, and using a custom domain came with extra costs, which gave me pause.

As an alternative, I considered switching to velog or rewriting everything in Markdown and moving to Jekyll.

Using a Custom Domain with GitHub Pages

Tue, 10 Feb 2026 07:34:00 +0000

Overview

By default, GitHub Pages provides a URL in the format https://{account name}.github.io/{repo name}/

This document explains how to connect a custom domain.

Using a Subdomain

This is the case where you use a subdomain such as hugosample.plzhans.com.

DNS Settings

Add a CNAME record in your domain’s DNS settings.

HTTPS TLS/SSL Free vs Paid Certificates

Thu, 17 Mar 2022 16:48:00 +0900

Overview

HTTPS communication requires a TLS/SSL certificate and domain.

Certificates are issued for owned domains, and clients verify that the accessed domain matches the certificate’s domain.

This document organizes domain-specific certificate issuance methods from a practical perspective.

It focuses on practical choices and implementation rather than theory.
