Τι είναι το Schema Markup;
Το Schema Markup (Structured Data) είναι κώδικας που προσθέτεις στο HTML για να βοηθήσεις τις search engines να καταλάβουν καλύτερα το content σου. Το αποτέλεσμα; Rich snippets στα search results - stars, prices, availability, reviews - που αυξάνουν το CTR κατά 20-40%.
1. Rich Snippets: Product cards με stars, price, availability
2. Higher CTR: 20-40% περισσότερα clicks vs plain results
3. Better Rankings: Η Google προτιμά well-structured content

Testing & Validation Tools
ALWAYS test your schema markup before going live. Λάθη στο schema = no rich snippets (ή χειρότερα, Google penalties).
2. Fake reviews/ratings: Google penalizes this heavily
3. Wrong currency format: Use "EUR" not "€"
4. Old dates: priceValidUntil must be future date
5. Broken URLs: All URLs must be absolute and working
