Modern and flexible SEO Bundle for Symfony 6/7 projects. Easily manage meta tags, OpenGraph, Twitter cards, canonical URLs, hreflangs, and verification tags.

🧭 Roadmap (Post-2.0)

🟥 Priority 1: Full SEO "out-of-the-box"

🧩 Support JsonLd + JsonLdMulti rendering helpers
🧠 Add schema.org presets (Article, Product, Event, etc.)
🌐 Integrate with sitemap generator (e.g., via Symfony event or SitemapProviderInterface)
🧷 Provide Google Tag Manager (GTM) support
🧲 Provide Meta Pixel support (Facebook)

🟧 Priority 2: Enhanced social sharing support

🖼️ og:image object support: url, width, height, alt, type
🎥 og:video support with full metadata
🧵 Multiple og:image / og:video entries
🎯 og:type configuration (article, product, etc.)
📌 Pinterest meta tags (pinterest:description, pinterest:image)
💼 LinkedIn-specific sharing optimization

🟨 Priority 3: Developer Experience & Flexibility

🧰 Symfony UX Component for real-time preview of tags in dev mode
🧪 PHPUnit constraint: assertSeoRenderedContains($tag)
🧬 Full extensibility via custom SeoRenderStrategyInterface
📦 Export configuration to JSON/LD, XML for third-party SEO analysis
📖 Recipe / packagist recipe for easy install with Flex

✅ Done

Rewrite listeners for flexibility and testability
Add support for localized defaults (en/uk/…) and translatable attributes
Add SeoMetaRenderOptions (include_title, skip_empty, etc.)
Add SeoTagHtmlBuilder for rendering
Add new SeoMeta flags (noIndex, disableDefaults, etc.)
Add canonical generator with query filtering
Add granular disabling via config/environment

📦 Installation

Require the bundle via Composer:

composer require gurtok/seo-bundle

If you're using Symfony Flex, the bundle will be registered automatically. Otherwise, manually add to config/bundles.php:

return [
    Gurtok\SeoBundle\GurtokSeoBundle::class => ['all' => true],
];

⚙️ Configuration

Create a config file config/packages/gurtok_seo.yaml:

gurtok_seo:
    allow_custom_meta: false         # Allow setting custom meta tags (true/false)
    auto_inject_response: true       # Auto-insert SEO meta into <head> if not manually called
    excluded_paths:
        - '/admin'
        - '/api'
    canonical_excluded_query_keys:
        - 'utm_source'
        - 'utm_medium'
        - 'utm_campaign'
        - 'utm_term'
        - 'utm_content'
        - 'ref'
        - 'fbclid'
        - 'page'
    defaults:
        title: { en: 'Default Title', uk: 'Типовий заголовок' } # Default title for the site
        title_separator: ' | '
        description: { en: 'Default description', uk: 'Типовий опис' }
        auto_canonical: true         # Automatically generate canonical URL
        meta:
            robots: 'index, follow'
        og:
            type: 'website'
        twitter:
            card: 'summary_large_image'
        verifications:
            google-site-verification: 'abc123'
        no_index: false              # Set to true if the site should not be indexed by search engines
        is_adult_content: false      # Set to true if the content is adult-oriented and will be marked as such

Note: The default locale is automatically taken from %kernel.default_locale% (usually configured in framework.yaml).

Example framework.yaml:

framework:
    default_locale: 'en'

🚀 Usage

Using the Attribute on Controllers

You can define SEO metadata directly via PHP 8+ attributes:

use Gurtok\SeoBundle\Attribute\SeoMeta;

#[SeoMeta(
    title: 'Homepage',
    titlePrefix: 'MySite',
    titleSeparator: ' ~ ',
    description: 'Welcome to our amazing website!',
    canonical: 'https://example.com',
    meta: ['robots' => 'index, follow'],
    og: [
        'title' => 'Homepage OG',
        'image' => 'https://example.com/image.jpg',
    ],
    twitter: ['card' => 'summary_large_image'],
    verifications: ['google-site-verification' => 'your-verification-code'],
    hreflangs: [
        'en' => 'https://example.com',
        'uk' => 'https://example.com/uk'
    ],
    noIndex: false,
    isAdultContent: false,
    disableDefaults: false
)]
public function __invoke()
{
    // ...
}

You can place the attribute either on the controller method or on the class — method attribute has priority.

Localized Titles and Descriptions

You can specify translations via arrays:

#[SeoMeta(
    title: [
        'en' => 'Homepage',
        'uk' => 'Головна сторінка'
    ],
    description: [
        'en' => 'Welcome!',
        'uk' => 'Ласкаво просимо!'
    ]
)]

The bundle automatically detects the current request locale (RequestStack) and uses the localized value. Fallback is the default locale from %kernel.default_locale%, or the first available value.

🎨 Twig integration

In your Twig layout (base.html.twig):

<head>
    {{ seo() }}
</head>

This will render:

<title> tag
<meta> description
<meta> robots
OpenGraph tags
Twitter card tags
Canonical link
Hreflang alternate links
Verification meta tags

🔍 Twig Functions

Twig Function	Description
`seo()`	Renders everything (title + meta + OG + Twitter + etc)
`seo_title()`	Renders only `<title>` tag
`seo_meta()`	Renders only `<meta>` tags
`seo_og()`	Renders OpenGraph tags
`seo_open_graph()`	Alias for `seo_og()`
`seo_twitter()`	Renders Twitter card tags
`seo_hreflangs()`	Renders hreflang links
`seo_verification()`	Renders verification tags

⚙️ Twig Function Options

Functions seo() and seo_meta() accept an optional options array:

{{ seo({ include_title: true, skip_empty: true }) }}

include_title (bool, default true) — whether to include the <title> tag.
skip_empty (bool, default true) — skip rendering empty meta fields.

🔥 Auto Injection (Optional)

If you forget to call {{ seo() }} manually in Twig, and auto_inject_response is enabled (default true), SeoBundle will automatically inject SEO meta before </head> during the HTTP Response phase.

📘 Full Example

# config/packages/gurtok_seo.yaml
gurtok_seo:
    allow_custom_meta: true
    auto_inject_response: true
    excluded_paths:
        - '/admin'
        - '/api'

Controller:

use Gurtok\SeoBundle\Attribute\SeoMeta;

#[SeoMeta(
    title: 'Blog',
    titleSeparator: ' * ',
    description: 'Latest articles and news.',
    og: ['title' => 'Blog OG', 'type' => 'website'],
    twitter: ['card' => 'summary'],
)]
class BlogController
{
    public function __invoke(SeoManager $seoManager)
    {
        // get post data, from database or API
        $seoManager->setTitlePrfix('Post Name');
        
        // ...
    }
}

Twig:

<head>
    {{ seo() }}
</head>

Result in HTML:

<title>Post * Blog</title>
<meta name="description" content="Latest articles and news.">
<meta property="og:title" content="Blog OG">
<meta property="og:type" content="website">
<meta name="twitter:card" content="summary">
