Metadata Migration

Introduction to Metadata Migration

Metadata migration is a critical component of every CMS migration. It ensures that all SEO-relevant elements of a website are correctly transferred to the new system. Without careful metadata migration, significant ranking losses and traffic declines can occur.

What is Metadata?

Metadata is structured information about a web page that helps Search bots understand and evaluate content. It includes both technical and content elements that directly influence ranking.

Technical Metadata

• Title Tags
• Meta Descriptions
• Meta Search terms (deprecated)
• Canonical URLs
• Meta Robots Tags
• OG tags Tags
• Twitter Card Tags

Structured Metadata

• Schema.org Markup
• JSON-LD
• Microdata
• RDFa

Before migration, a complete inventory of all existing metadata must be performed:

2. Use Crawling Tools

Modern SEO tools enable efficient capture of all metadata:

Best Practices for Title Tags

Title tags are the most important SEO element and must be handled with particular care during migration:
