TYPO3 SEO Configuration

Compatibility: TYPO3 v13.x and v14.x (v14 preferred) All SEO configurations in this skill work on both v13 and v14.

1. Core SEO Extension Setup

Installation

ddev composer require typo3/cms-seo
ddev typo3 extension:activate seo
ddev typo3 cache:flush

Page Properties SEO Tab

After installation, pages have an "SEO" tab with:

• seo_title - Override page title for search engines
• description - Meta description
• og_title, og_description, og_image - Open Graph
• twitter_title, twitter_description, twitter_image - Twitter Cards
• canonical_link - Canonical URL override
• no_index, no_follow - Robot directives

2. Meta Tags Configuration

TypoScript Setup (v13/v14)

page {
    meta {
        # Basic meta tags
        viewport = width=device-width, initial-scale=1
        robots = index,follow
        author = webconsulting
        
        # Open Graph (auto-filled by EXT:seo if page properties set)
        og:type = website
        og:site_name = {$site.name}
        og:locale = de_AT
        
        # Twitter Cards
        twitter:card = summary_large_image
        twitter:site = @webconsulting
    }
}

Dynamic Meta Description

page.meta.description = TEXT
page.meta.description {
    # Fallback chain: page description > parent description > site description
    data = page:description // levelfield:-1,description,slide // {$site.description}
    htmlSpecialChars = 1
}

Hreflang Tags (Multi-Language)

EXT:seo automatically generates hreflang tags based on site configuration:

# config/sites/main/config.yaml
languages:
  - languageId: 0
    locale: de_AT
    hreflang: de-AT
    title: Deutsch
    
  - languageId: 1
    locale: en_GB
    hreflang: en-GB
    title: English

3. XML Sitemap Configuration

Basic Sitemap Setup

# config/sites/main/config.yaml
base: 'https://example.com/'
routeEnhancers:
  PageTypeSuffix:
    type: PageType
    map:
      sitemap.xml: 1533906435

TypoScript Sitemap Configuration (v13/v14)

plugin.tx_seo {
    config {
        xmlSitemap {
            sitemaps {
                # Pages sitemap (default)

                    provider = TYPO3\CMS\Seo\XmlSitemap\PagesXmlSitemapDataProvider
                    config {
                        excludedDoktypes = 3,4,6,7,199,254,255
                        additionalWhere = no_index = 0 AND nav_hide = 0
                    }
                }
                
                # News sitemap (example for EXT:news)
                news {
                    provider = GeorgRinger\News\Seo\NewsXmlSitemapDataProvider

                        lastModifiedField = tstamp
                        changeFreqField = sitemap_changefreq
                        priorityField = sitemap_priority
                        additionalWhere = {#hidden} = 0 AND {#deleted} = 0
                        pid = 123
                        url {
                            pageId = 45
                            fieldToParameterMap {
                                uid = tx_news_pi1[news]
                            }

                    provider = TYPO3\CMS\Seo\XmlSitemap\RecordsXmlSitemapDataProvider
                    config {
                        table = tx_shop_domain_model_product
                        sortField = title
                        lastModifiedField = tstamp
                        pid = 100
                        recursive = 2
                        url {

                            fieldToParameterMap {
                                uid = tx_shop_pi1[product]
                            }
                            additionalGetParameters {
                                tx_shop_pi1.controller = Product

                            }
                        }
                    }
                }
            }
        }
    }
}

Sitemap Index

Access sitemap at: https://example.com/sitemap.xml

Individual sitemaps:

• https://example.com/sitemap.xml?sitemap=pages
• https://example.com/sitemap.xml?sitemap=news

4. Robots.txt Configuration

Static Robots.txt

# public/robots.txt
User-agent: *
Allow: /

# Disallow TYPO3 backend and system directories
Disallow: /typo3/
Disallow: /typo3conf/
Disallow: /typo3temp/

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

Dynamic Robots.txt via TypoScript

# Generate robots.txt dynamically
robotstxt = PAGE
robotstxt {
    typeNum = 9999
    config {
        disableAllHeaderCode = 1
        additionalHeaders.10.header = Content-Type: text/plain; charset=utf-8
    }
    
    10 = TEXT
    10.value (
User-agent: *
Allow: /
Disallow: /typo3/
Disallow: /typo3conf/
Disallow: /typo3temp/

Sitemap: {getEnv:TYPO3_SITE_URL}sitemap.xml
    )
}

Route enhancement:

# config/sites/main/config.yaml
routeEnhancers:
  PageTypeSuffix:
    type: PageType
    map:
      robots.txt: 9999

5. Canonical URLs

Automatic Canonicals

EXT:seo generates canonical tags automatically. Configure in site:

# config/sites/main/config.yaml
base: 'https://example.com/'
baseVariants:
  - base: 'https://staging.example.com/'
    condition: 'applicationContext == "Development"'

Manual Canonical Override

In page properties SEO tab, set "Canonical URL" field.

Via TypoScript:

page.headerData.100 = TEXT
page.headerData.100 {
    value = <link rel="canonical" href="https://example.com/specific-page" />
}

6. Structured Data (JSON-LD)

Organization Schema

page.headerData.200 = TEXT
page.headerData.200.value (
<script type="application/ld+json">
{
    "@context": "https://schema.org",
    "@type": "Organization",
    "name": "webconsulting",
    "url": "https://webconsulting.at",

        "contactType": "customer service"
    }
}
</script>

lib.breadcrumbSchema = COA
lib.breadcrumbSchema {
    10 = TEXT
    10.value = <script type="application/ld+json">{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[
    
    20 = HMENU
    20 {
        special = rootline
        special.range = 0|-1
        1 = TMENU
        1 {
            NO = 1
            NO {
                doNotLinkIt = 1
                stdWrap.cObject = COA
                stdWrap.cObject {
                    10 = TEXT
                    10.value = {"@type":"ListItem","position":
                    20 = TEXT
                    20.data = register:count_HMENU_MENUOBJ
                    30 = TEXT
                    30.value = ,"name":"
                    40 = TEXT
                    40.field = nav_title // title
                    40.htmlSpecialChars = 1
                    50 = TEXT
                    50.value = ","item":"
                    60 = TEXT
                    60.typolink.parameter.field = uid

            }
        }
    }
    
    30 = TEXT
    30.value = ]}</script>
    30.replacement {
        10.search = ,]}
        10.replace = ]}
    }
}

page.headerData.300 < lib.breadcrumbSchema

Advanced Structured Data with EXT:schema

# Install schema extension for advanced structured data
ddev composer require brotkrueml/schema

<?php
// In a PSR-14 event listener
use Brotkrueml\Schema\Type\TypeFactory;
use Brotkrueml\Schema\Manager\SchemaManager;

#[AsEventListener]
final class AddSchemaListener
{
    public function __construct(
        private readonly TypeFactory $typeFactory,
        private readonly SchemaManager $schemaManager,
    ) {}

    public function __invoke(SomeEvent $event): void
    {
        $organization = $this->typeFactory->create('Organization')
            ->setProperty('name', 'My Company')
            ->setProperty('url', 'https://example.com');
        
        $this->schemaManager->addType($organization);
    }
}

7. Performance SEO

Core Web Vitals Optimization

# Preload critical resources

<link rel="preconnect" href="https://fonts.googleapis.com">
<link rel="dns-prefetch" href="https://www.google-analytics.com">

# Lazy load images (built-in v13/v14)
lib.contentElement {
    settings {
        media {
            lazyLoading = lazy
        }
    }
}

Image Optimization (v13/v14)

// config/system/additional.php
$GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_allowUpscaling'] = false;

// WebP is automatically generated in v13/v14 when supported

# Responsive images
tt_content.image.settings.responsive_image_rendering = 1
