This article only covers Google SEO. No other search engines. Reason: Google has the traffic share, doing Google well is enough.

Structured Data

The most important part. Structured data lets Google show rich results in search — publish date, author, summary.

Every article gets JSON-LD injected at build time:

{{ if .IsPage }}
<script type="application/ld+json">
{
 "@context": "https://schema.org",
 "@type": "Article",
 "headline": "{{ .Title }}",
 "datePublished": "{{ .Date.Format "2006-01-02T15:04:05Z07:00" }}",
 "dateModified": "{{ .Lastmod.Format "2006-01-02T15:04:05Z07:00" }}",
 "author": {
 "@type": "Person",
 "name": "{{ .Site.Params.author }}"
 },
 "description": "{{ if .Description }}{{ .Description }}{{ else }}{{ .Summary | plainify }}{{ end }}",
 "url": "{{ .Permalink }}"
 {{ with .Params.tags }}
 ,"keywords": "{{ delimit . ", " }}"
 {{ end }}
}
</script>
{{ end }}

One thing to note: dates in JSON-LD must be ISO 8601 format (2025-03-17T10:43:00+08:00). If you only provide date without timezone, Google might not parse it correctly. Hugo’s .Date.Format outputs timezone by default, but if frontmatter doesn’t have timezone info, it assumes UTC — might not match your actual publish time.
