Analyze any domain name for brandability, memorability, SEO fitness, and estimated value. Get 20+ alternative suggestions and compare TLD options.
Compare your domain name across popular top-level domains. Prices are typical annual registration costs.
To verify actual domain availability, use one of these trusted registrars. This tool provides analysis and suggestions; real-time WHOIS lookups require a registrar.
A domain name is a human-readable address that maps to an IP address through the Domain Name System (DNS). When you type example.com into your browser, DNS servers translate that name into an IP address like 93.184.216.34, which your browser uses to connect to the web server.
A domain name has several parts. In www.example.com, "com" is the top-level domain (TLD), "example" is the second-level domain (the part you register), and "www" is a subdomain. The TLD is managed by a registry operator (like Verisign for .com), while you lease the second-level domain through a registrar.
Domain registration works through a hierarchy. ICANN oversees the global DNS. Registry operators manage specific TLDs. Registrars (like Namecheap or Cloudflare) are accredited companies that sell registrations to the public. When you register a domain, you are leasing the right to use that name for a set period, typically 1 to 10 years, renewable indefinitely as long as you pay the annual fee.
Domain values depend on length (shorter is more valuable), TLD (.com is the most valuable), keyword strength (dictionary words command premiums), brandability, existing traffic, and backlink profile. Single-word .com domains routinely sell for six to seven figures. Most newly registered domains are worth only their registration fee until developed.
This tool analyzes your domain name for quality and generates alternatives. To verify actual availability, click through to a registrar like Namecheap, Cloudflare, or Porkbun, which perform real-time WHOIS lookups. Availability changes by the minute, so check and register promptly if you find a name you want.
A brandable domain is short (under 12 characters), easy to pronounce, easy to spell after hearing it spoken, and visually clean. Avoid hyphens and numbers. The best brand names are distinctive and do not describe the product literally. Think Spotify, not music-streaming-service.com.
Google treats new generic TLDs (.io, .app, .dev) the same as .com for ranking. However, .com domains tend to get higher click-through rates in search results due to user familiarity and trust. Country-code TLDs (.uk, .de) help with geo-targeting for local search.
Standard .com registration costs $8 to $15 per year. Newer TLDs vary: .io is $30-60/year, .ai is $70-90/year, .dev is $12-15/year. Premium aftermarket domains can cost hundreds to millions. Always check renewal pricing, as introductory prices may differ from ongoing costs.
For brand protection, registering .com, .net, and .org variants is good practice. At minimum, secure the .com even if your primary site uses a different TLD. Redirect all variants to your primary domain with 301 redirects to consolidate search authority.
Domain squatting (cybersquatting) is registering domains matching established trademarks to profit from resale. It is illegal under the Anticybersquatting Consumer Protection Act (ACPA) and can be challenged through ICANN's UDRP. Registering generic or creative names that do not infringe trademarks is legal. Domain investing in generic names is a legitimate industry.
