10.7 Avoid These SEO Mistakes

Mistake	Why it hurts	Correct way
Using ?lang=es parameter	Google treats it as one site	Use directories or subdomains
Hiding languages with noindex	Wastes crawl budget	Let Google crawl everything
Same content in multiple languages	Duplicate content penalty	Always translate or use proper hreflang
Forgetting to translate alt text	Misses image SEO	Enable Media Translation + translate alt
