KartenSyndikat
How we rebuilt 5 broken product collections, fixed hreflang across 22 European markets, and deployed TCG product schema to put KartenSyndikat on page 1 for “Pokémon Booster kaufen” in 60 days.
Visit WebsiteChallenges Faced
KartenSyndikat launched in 2025 with a strong product range but critical structural SEO failures from day one. Five product categories linked to placeholder URLs, the title misrepresented the inventory, and 22 European markets had no hreflang.
Title Misrepresented Inventory
The page title “Kartensyndikat | Premium Japanese Pokémon Card Shop” misrepresented a store selling 4 games in 5 languages — German, English, Japanese, Korean, and Chinese editions.
Five Categories Pointing to Placeholders
Yu-Gi-Oh!, One Piece, Lorcana, Korean Pokémon, and Chinese Pokémon categories all linked to /collections/frontpage — an empty placeholder URL with no products or content.
No Hreflang for 22 EU Markets
The store shipped to 22 European countries with a German-language interface but had zero hreflang implementation — causing duplicate content issues and no geo-targeting for any EU locale.
Zero Product Schema
No Product or CollectionPage schema on any booster, display, or collection listing — completely ineligible for Google Shopping rich results across all European markets.
