Project description

wagtail-herald

Philosophy

SEO optimization shouldn't require deep technical knowledge. While Wagtail provides excellent content management, setting up proper meta tags, Open Graph, Twitter Cards, and Schema.org structured data requires significant manual work.

wagtail-herald provides a comprehensive SEO solution with just two template tags. Site-wide settings are managed through Wagtail's admin interface, while page-specific SEO can be configured per-page with sensible defaults.

The goal is to help content editors achieve best-practice SEO without touching code, while giving developers full control when needed.

Key Features

Simple Integration - Just 2 template tags: {% seo_head %} and {% seo_schema %}
Site-wide Settings - Configure Organization, favicons, social profiles from admin
Page-level SEO - Uses Wagtail's built-in SEO fields + OG image override
13+ Schema Types - Article, Product, FAQ, Event, LocalBusiness, and more
Automatic BreadcrumbList - Generated from page hierarchy
Locale Support - Per-page language/region targeting with {% page_lang %} tag
Analytics Integration - GTM, GA4, Facebook Pixel, Microsoft Clarity from admin
robots.txt Management - Configure robots.txt from admin interface
Japanese UI - Full Japanese localization for admin interface

Installation

pip install wagtail-herald

Add to your INSTALLED_APPS:

# settings.py
INSTALLED_APPS = [
    # ...
    'wagtail.contrib.settings',  # Required
    'wagtail_herald',
    # ...
]

Quick Start

1. Add Template Tags

{% load wagtail_herald %}
<!DOCTYPE html>
<html>
<head>
    {% seo_head %}
</head>
<body>
    <!-- Your content -->

    {% seo_schema %}
</body>
</html>

That's it! The template tags handle everything:

{% seo_head %} - Meta tags, OG, Twitter Card, favicon, hreflang, analytics scripts
{% seo_schema %} - All JSON-LD structured data

2. Configure Site Settings

Go to Settings > SEO Settings in Wagtail admin to configure:

Organization name, logo, type
Social media profiles (Twitter, Facebook, etc.)
Default OG image
Favicon and Apple Touch Icon
Google/Bing site verification
Analytics (GTM, GA4, Facebook Pixel, Clarity)

3. Add SEO Mixin to Pages (Optional)

For page-level SEO control, add the mixin to your page models:

from wagtail.models import Page
from wagtail_herald.models import SEOPageMixin

class ArticlePage(SEOPageMixin, Page):
    # Your fields...

    content_panels = Page.content_panels + [
        # Your panels...
    ]

    promote_panels = Page.promote_panels + SEOPageMixin.seo_panels

This adds an "SEO" panel in the page editor with:

OG image override
Schema type selector (Article, Product, FAQ, etc.)
Locale selector (ja_JP, en_US, en_GB, etc.)
noindex/nofollow options
Canonical URL override

Note: For SEO title and meta description, use Wagtail's built-in seo_title and search_description fields in the Promote tab. The template tags automatically use these fields.

    'DEFAULT_ROBOTS': 'index, follow',

    # OG image rendition filter (1200x630 is optimal for social sharing)

}

Locale Support

wagtail-herald provides per-page language and region targeting for mixed-language content.

Use Case: Mixed Language Content

Write Japanese and English articles on the same site by selecting locale per page:

{% load wagtail_herald %}
<!DOCTYPE html>
<html lang="{% page_lang %}">
<head>
    {% seo_head %}
    <!-- Outputs: <meta property="og:locale" content="ja_JP"> -->
</head>

{% page_lang %} - Returns language code (e.g., ja, en)
{% page_locale %} - Returns full locale (e.g., ja_JP, en_US)
{% seo_head %} - Automatically includes og:locale meta tag

Available Locales

Locale	Language
`ja_JP`	日本語 (日本)
`en_US`	English (US)
`en_GB`	English (UK)
`zh_CN`	中文 (简体)
`zh_TW`	中文 (繁體)
`ko_KR`	한국어
`fr_FR`	Français (France)
`de_DE`	Deutsch (Deutschland)
`es_ES`	Español (España)
`pt_BR`	Português (Brasil)

Set the default locale in Settings > SEO Settings, then override per-page using the SEOPageMixin.

robots.txt Management

Configure robots.txt from Wagtail admin without editing files.

Setup

Add the robots.txt view to your urls.py:

from wagtail_herald.views import robots_txt

urlpatterns = [
    path('robots.txt', robots_txt, name='robots_txt'),
    # ... other urls
]

Configuration

Go to Settings > SEO Settings and edit the robots.txt content:

User-agent: *
Allow: /
Disallow: /admin/
Disallow: /search/

Sitemap: https://example.com/sitemap.xml

If no custom content is set, a sensible default is used.
