The Complete Guide to Domain Availability Checking for SEO Success
Domain availability checking is crucial for brand protection, business expansion, and SEO strategy. A domain availability checker helps find available domain names across multiple top-level domains (TLDs), ensuring you secure the perfect domain for your website. This comprehensive guide explores domain registration, availability checking, and best practices for domain selection.
What is Domain Availability?
Domain availability refers to whether a specific domain name is registered and in use, or available for registration. Available domains can be registered through domain registrars, while taken domains are already owned by someone else.
Domain Structure
- Second-level domain (SLD): The main name (e.g., 'google')
- Top-level domain (TLD): The extension (e.g., '.com', '.org')
- Fully qualified domain name (FQDN): Complete domain (e.g., 'google.com')
