## 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
- **ads.txt Management** - Configure ads.txt (Authorized Digital Sellers) from admin interface
- **security.txt Management** - Configure security.txt (RFC 9116) from admin interface
- **Custom Code Injection** - Add custom HTML to head and body from admin
- **Japanese UI** - Full Japanese localization for admin interface

## Installation

```bash
pip install wagtail-herald
```

Add to your `INSTALLED_APPS`:

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

## Quick Start

### 1. Add Template Tags

```html
{% 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:

```python
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.

### 4. Override SEO per Sub-route (RoutablePageMixin)

When using `RoutablePageMixin`, individual sub-routes often represent different content items that need their own SEO metadata. Pass well-known keys through `context_overrides` and `{% seo_head %}` will use them instead of the page object's fields.

**Supported context keys:**

| Key | Overrides |
|-----|-----------|
| `seo_title` | Page title and OG/Twitter title |
| `seo_description` | Meta description and OG/Twitter description |
| `seo_canonical_url` | Canonical URL and `og:url` |
| `seo_og_image` | OG image and Twitter image (Wagtail Image instance) |

```python
from wagtail.contrib.routable_page.models import RoutablePageMixin, path
from wagtail.models import Page

class BlogIndexPage(RoutablePageMixin, Page):

    @path("<slug:slug>/")
    def detail(self, request, slug):
        item = get_object_or_404(BlogPost, slug=slug)
        return self.render(request, context_overrides={
            "seo_title": item.name,
            "seo_description": item.summary,
            "seo_canonical_url": request.build_absolute_uri(),
        })
```

Any key not provided falls back to the page object's own fields, so you only need to specify what differs per sub-route.

## Supported Schema Types

### Site-wide (Automatic)
- **WebSite** - Site search box support
- **Organization** - Company/organization info

### Page-selectable
| Type | Use Case |
|------|----------|
| WebPage | General pages (default) |
| Article | General articles |
| NewsArticle | News content |
| BlogPosting | Blog posts |
| Product | Product pages |
| LocalBusiness | Store/business info |
| Service | Service descriptions |
| FAQPage | FAQ pages |
| HowTo | How-to guides |
| Event | Events |
| Person | Profile pages |
| Recipe | Recipes |
| Course | Online courses |
| JobPosting | Job listings |

### Automatic
- **BreadcrumbList** - Generated from page hierarchy

## Configuration

All settings are optional and configured through Wagtail admin:

### Site Settings (Admin UI)

| Organization type | Corporation, LocalBusiness, Person, etc. (use Person for individual/personal sites) |
| Organization logo | Logo image for Schema |
| Twitter handle | @username (without @) |
| Facebook URL | Facebook page URL |
| Default locale | Default og:locale (e.g., en_US, ja_JP) |
| Default OG image | Fallback image for social sharing (1200x630) |
| Favicon (SVG) | SVG favicon for modern browsers (recommended) |
| Favicon (PNG) | PNG fallback, minimum 48x48 (Google requirement) |
| Apple Touch Icon | iOS home screen icon (180x180) |
| GTM Container ID | Google Tag Manager (GTM-XXXXXX) |
| robots.txt content | Custom robots.txt content |

| security.txt content | Security vulnerability reporting info per RFC 9116 (returns 404 if empty) |
| Custom head HTML | Custom HTML for `<head>` section |
| Custom body end HTML | Custom HTML before `</body>` (chat widgets, etc.) |

### Django Settings (Optional)

```python
# settings.py
WAGTAIL_HERALD = {
    # Default robots meta (can be overridden per-page)
    'DEFAULT_ROBOTS': 'index, follow',

    # OG image rendition filter (1200x630 is optimal for social sharing)
    'OG_IMAGE_FILTER': 'fill-1200x630',

    # Favicon rendition filter (48x48 minimum recommended by Google)
    'FAVICON_FILTER': 'fill-48x48',
}
```

## 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:

```html
{% 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 wagtail-herald URLs to your `urls.py`:

```python
from django.urls import include, path

urlpatterns = [
    path('', include('wagtail_herald.urls')),
    # ... 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 left empty, a sensible default is generated (allow all crawlers, include sitemap URL).

## ads.txt Management

Configure ads.txt (Authorized Digital Sellers) from Wagtail admin without editing files.

### Setup

Include wagtail-herald URLs in your `urls.py` (same as robots.txt):

```python
from django.urls import include, path

urlpatterns = [
    path('', include('wagtail_herald.urls')),
    # ... other urls
]
```

### Configuration

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

```
google.com, pub-0000000000000000, DIRECT, f08c47fec0942fa0
```

Unlike robots.txt, if the ads.txt field is left empty, the `/ads.txt` endpoint returns a **404** response rather than generating default content.

## security.txt Management

Configure security.txt ([RFC 9116](https://www.rfc-editor.org/rfc/rfc9116)) from Wagtail admin without editing files. This file helps security researchers report vulnerabilities through the standardized `/.well-known/security.txt` path.

### Setup

Include wagtail-herald URLs in your `urls.py` (same as robots.txt and ads.txt):

```python
from django.urls import include, path

urlpatterns = [
    path('', include('wagtail_herald.urls')),
    # ... other urls
]
```

### Configuration

Go to **Settings > SEO Settings** and edit the security.txt content. Per RFC 9116, the **Contact** and **Expires** fields are required:

```
Contact: mailto:security@example.com
Expires: 2026-12-31T23:59:59z
Preferred-Languages: en, ja
Canonical: https://example.com/.well-known/security.txt
```

If the security.txt field is left empty, the `/.well-known/security.txt` endpoint returns a **404** response.

## Requirements

| Python | Django | Wagtail |
|--------|--------|---------|
| 3.10+  | 4.2, 5.1, 5.2 | 6.4, 7.0, 7.2 |
