How to Use These Tools for Free Website Ideas

1. Start with Keywords: Enter 1–2 words related to your website (e.g., "eco fashion" for a sustainable clothing site). Tools like Nameboy or Instant Domain Search will generate variations like ecofashionhub.com or greenstyle.ai.
2. Check Availability: All listed tools verify real-time availability to avoid wasted time on taken names. For example, DomainWheel shows registration options directly.
3. Explore TLDs: In 2025, .ai and .io are surging for tech sites, while .shop suits e-commerce. Use filters to prioritize .com for broad appeal.
4. Refine and Register: Save favorites (e.g., Namelix learns from this). Once chosen, register via the tool's partner (e.g., Bluehost for Nameboy offers free domains with hosting). Aim for short (6–15 characters), memorable names without hyphens or numbers.
5. Tips for 2025: Incorporate SEO keywords for better rankings, but prioritize brandability. Check trademarks via USPTO or tools like Atom.com. Secure social handles too for consistency.
