Promotional text in title

Google flags titles containing 'SALE', 'Free Shipping', 'Best Deal', or similar promotional language. The product can still serve but ranking is demoted.

Titles built for in-store merchandising often carry over to feeds with promotional language baked in.

1. Strip promotional words from titles. Keep brand, name, key attributes only.
2. Move discounts to sale_price + sale_price_effective_date.
3. Move shipping callouts out of titles entirely.
