FAQ
TLD questions
What is a TLD (Top-Level Domain)?
A TLD is the last part of a domain name, like .com, .io, or .ai. It appears after the final dot in a web address. TLDs help categorize websites and can signal your business type to visitors.
Which TLD is best for my startup?
.com is the gold standard for recognition, but good names are often taken. For tech startups, .io is the de facto alternative. .ai is perfect for AI companies, .app for mobile apps, and .dev for developer tools. Choose based on availability and industry fit.
Does my TLD affect SEO?
Google treats most TLDs equally for SEO purposes. Your content and backlinks matter more than your extension. However, .com may have a slight trust advantage with users. Country-code TLDs (.co.uk, .de) can help with local SEO.
What's the difference between .io and .ai?
.io is general-purpose tech/startup TLD used by companies like Linear.app, Notion.so. .ai specifically signals artificial intelligence and is used by companies like Stability.ai, Character.ai. Choose .ai if AI is core to your product.
Are .app and .dev secure?
Yes! .app and .dev require HTTPS encryption by default, making them inherently more secure. This is enforced at the registry level, so all .app and .dev sites must have SSL certificates.
Why are some TLDs more expensive?
Pricing varies by registry policies and demand. .ai is expensive because Anguilla (the country that owns it) sets high prices due to AI industry demand. .io is pricier due to startup popularity. Classic TLDs like .com and .net have stable, moderate pricing.
