The .KAUFEN extension is one of the strongest niche TLDs for the German e-commerce and affiliate marketing market. “Kaufen” means “to buy”, making it ideal for product reviews, deals, online shops, and price-comparison sites.
Below are the most effective tips to choose, register, and use a .KAUFEN domain successfully.
1. Choose Short, Clear, Buy-Intent Keywords
The best .KAUFEN domains clearly signal what the customer will buy.
Best categories:
- Electronics → LaptopKaufen.kaufen, Fernseher.kaufen
- Automobiles → Auto.kaufen, TeslaKaufen.kaufen
- Household → Staubsauger.kaufen, Küche.kaufen
- Fitness & beauty → Fitnessgerät.kaufen, Makeup.kaufen
- Consumer finance → Versicherung.kaufen, Kredit.kaufen
Avoid:
- Very long phrases
- Complicated compound words
- Non-German keywords (unless global brand)
2. Match Exact Search Intent
If Germans search “X kaufen,” then a domain ending in .kaufen is a perfect match for SEO + CTR.
Strong examples:
- Schuhe.kaufen
- Smartphone.kaufen
- Matratze.kaufen
- Winterreifen.kaufen
These domain names immediately answer “Where can I buy this?”
3. Prefer Singular Over Plural
For e-commerce and comparison sites, singular keywords convert better because people often search for the exact item:
✔ Laptop.kaufen > Laptops.kaufen
✔ Auto.kaufen > Autos.kaufen
✔ Waschmaschine.kaufen > Waschmaschinen.kaufen
4. Avoid Over-Branding; Keep It Functional
.KAUFEN works best as a descriptive performance domain, not a brand-building domain.
Good:
- KreditKaufen.kaufen
- GamingPC.kaufen
- NikeSchuhe.kaufen
Weak:
- MegaSuperOutlet.kaufen (too vague)
- MaxStore.kaufen (not useful for SEO)
5. Combine with High-Value Niches
To maximize revenue or resale value, choose industries where German buyers spend money online:
High-value niches for .KAUFEN:
- Electronics
- Mobility & auto
- Home appliances
- Insurance & finance
- Pet products
- Furniture
- Baby products
- Beauty & health
These categories have strong affiliate commissions, making the domain more valuable.
6. Keep It Easy to Spell and Type
German users prefer domains that:
- Are short
- Don’t require hyphens
- Are simple to pronounce
Avoid:
- Hyphens
- Long compound words (>18 characters)
- Uncommon foreign spellings
7. Good for Affiliate, Testberichte & Preisvergleich Sites
If you plan to build:
- Affiliate site
- Testberichte website
- Vergleich (comparison) portal
- Gutschein (deals) portal
then .KAUFEN is a perfect fit.
Example:
- Staubsauger.kaufen → Dyson, Miele, Bosch affiliate links
- Handy.kaufen → Telekom, O2, Amazon
- Ebike.kaufen → High affiliate payouts
8. Register Multiple Variations (If Profitable)
To protect your idea or business model, consider registering:
- Singular + Plural
- Keyword + Kaufen
- Keyword on .de
- .kaufen + .shop (optional)
But only if the keywords have strong commercial value.
9. Check for Trademark Issues
If your domain includes a brand (e.g., Nike.kaufen, Apple.kaufen), you must check trademark restrictions.
Generic product names are much safer:
✔ Sportschuhe.kaufen
✔ Laptop.kaufen
✔ Reifen.kaufen
10. Look for Undervalued Premium Keywords
Many excellent product keywords in German remain unregistered in .KAUFEN.
Look for:
- One-word generics
- Seasonal keywords (Winterreifen, Luftreiniger, Klimaanlage)
- Evergreen consumer goods
11. Use .KAUFEN for Fast Monetization
This extension is ideal if you want to build:
- Amazon affiliate sites
- Partner program landing pages
- Dropshipping microstores
- Single-product funnels
A keyword like Staubsauger.kaufen can bring fast SEO traffic and high conversion rates.
12. Consider Resale Potential
Good .KAUFEN domains can sell to:
- E-commerce shops
- German affiliates
- Product comparison portals
- Agencies
- Niche brands
Value increases when:
- Keyword has high monthly searches
- The niche has strong buying intent
- Competitors want to own the keyword
