Dealing with duplicate content in TYPO3, or any content management system, involves a few steps to ensure that you maintain SEO best practices and provide a good user experience. Here's a guide on how to address duplicate content issues in TYPO3:

1. Identify Duplicate Content: Use tools like Google Search Console, Screaming Frog, or SEMrush to identify duplicate content on your website. Look for duplicate meta descriptions, title tags, and body content.
2. Canonical Tags: Implement canonical tags to tell search engines which version of a page should be considered the authoritative version. In TYPO3, you can set canonical tags using TypoScript or SEO extensions.
3. Redirects: Use 301 redirects to direct visitors (and search engines) from duplicate pages to the preferred page. This helps consolidate link equity. TYPO3's URL routing can be configured to handle redirects effectively.
4. Consistent URLs: Ensure consistent usage of URLs throughout your website. TYPO3 may generate different URLs for the same content due to different parameters. Use URL rewriting or the built-in routing feature to maintain clean, consistent URLs.
5. Configuration and Extensions: Check your TYPO3 configurations for settings that might lead to duplicate content, like allowing indexing of both http and https versions or trailing slashes. Use SEO extensions like cs_seo or seo_basics to manage and optimize meta tags and canonical URLs easily.
6. Content Structuring: Review how content is structured. Use TYPO3’s features like templating to keep content modular and avoid unnecessary duplication. Reusable content elements should be properly managed so they don't create separate indexable pages.
7. Manage Query Parameters: Use rel="canonical" tags or configure robots.txt to manage pages with significant query parameters that may lead to duplicate content. TYPO3's RealURL or the newer routing functionality can help manage query parameters efficiently.
8. Sitemap Adjustments: Ensure your XML sitemap only includes the preferred versions of your pages. TYPO3 extensions for sitemap generation can be adjusted to exclude duplicates.

By following these steps, you can effectively reduce and manage duplicate content issues in your TYPO3 setup, improving your site's SEO and user experience. Regular audits and updates are essential to keep your content and configurations in check.
