SEO toolkit for Wagtail CMS - meta tags, Open Graph, Twitter Cards, and Schema.org structured data

Project description

wagtail-herald

PyPI version CI codecov License: BSD-3-Clause Published on Django Packages

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 3 template tags: {% seo_head %}, {% seo_body %}, {% 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
  • Google Tag Manager - GTM integration with noscript fallback
  • robots.txt Management - Configure robots.txt from admin interface
  • Custom Code Injection - Add custom HTML to head and body from admin
  • 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 lang="{% page_lang %}">
<head>
    {% seo_head %}
</head>
<body>
    {% seo_body %}

    <!-- Your content -->

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

That's it! The template tags handle everything:

  • {% seo_head %} - Meta tags, OG, Twitter Card, favicon, GTM script, custom head HTML
  • {% seo_body %} - GTM noscript fallback, custom body end HTML
  • {% seo_schema %} - All JSON-LD structured data
  • {% page_lang %} - Language code for html lang attribute

2. Configure Site Settings

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

  • Organization name, logo, type
  • Social media profiles (Twitter, Facebook)
  • Default OG image and locale
  • Favicon and Apple Touch Icon
  • Google Tag Manager (GTM)
  • robots.txt content
  • Custom head/body HTML injection

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.
