SEO comparison, which is better for organic traffic?

Evaluate content, crawlable navigation, URL handling, redirects, canonical tags, sitemaps and structured data in the proposed implementation. Either platform can have useful content or technical mistakes. Before moving, identify existing search landing pages and preserve relevant destinations through tested redirects and internal links. Compare the actual controls and required development work rather than treating platform choice as a ranking guarantee. Keep the keyword roles of product, category and editorial pages distinct.
