Domain Extension Compare: Free TLD Comparison

This domain extension compare tool lines up TLDs such as .com, .io, .ai and .shop side by side. For each one you see the estimated yearly price, SEO value, trust, recognition and best use, so you can choose the extension that fits your brand and budget before you register anything.

What Is a Domain Extension (TLD)?

A domain extension, also called a top-level domain or TLD, is the part of a web address after the last dot. In mybrand.com, the extension is .com. Every extension belongs to a family, and the family affects price, rules and how visitors see your brand.

• Generic TLDs such as .com, .net and .org are not tied to a country. They are the most widely recognized.
• New generic TLDs such as .app, .shop, .agency and .studio describe an industry or purpose.
• Country-code TLDs such as .us, .uk, .de and .ca belong to a country or territory. A few, including .io, .co, .ai, .me and .tv, are sold worldwide and used as brandable alternatives.

The tool covers nearly 70 extensions across these groups, from long-standing ones to newer industry labels.

How to Use the Domain Extension Compare Tool

You can compare extensions in under a minute, and you do not need to type a domain name to get the comparison. Follow these steps:

1. Type your brand in the field labeled Your domain name (without extension, optional). Use only the name, for example mybrand, with no dot and no extension.
2. Look at the checklist under Select TLDs to Compare. The extensions .com, .net, .io and .ai are ticked by default.
3. Tick extra extensions you are considering and untick any you do not want in the comparison.
4. Click Compare Extensions.
5. Read the side-by-side results: price range, SEO value, trust, recognition, type, best use and a short note for each extension.
6. If you entered a name, use the one-click Register link next to an extension to check that exact domain with a registrar.

Leave the name field empty when you only want to learn how extensions differ. Add the name when you are ready to see your own brand with each ending.

Worked Example: Comparing mybrand Across Four Extensions

Say you run a small SaaS startup called mybrand and compare the four default extensions. The tool returns ranges like these:

Now do the math over three years. A .com costs about $30 to $45. An .io costs about $90 to $150. An .ai costs about $210 to $300. If your product is not AI-related, paying roughly six to seven times more for .ai buys you little.

The ratings point the same way. The .com extension scores the highest on SEO value, trust and recognition. The .io extension scores a step lower, but its tech audience knows it well. A sensible plan is to register mybrand.com if it is free, or mybrand.io if you sell to developers and .com is taken.

How to Read and Act on the Results

Each result column answers a different question, and the right extension is the one that balances all of them for your project. Here is how to read them.

Price

The price is an estimated yearly range, not a quote. Registrars set their own prices, and promotional first-year deals (common on cheap extensions like .xyz) often jump at renewal. Plan for the renewal cost, since you will pay it every year you keep the domain. A $1 first year is not a bargain if the renewal is $15.

SEO value, trust and recognition

These are quick guide ratings that show how familiar and credible an extension tends to look to people and to spam filters. A high trust rating, such as .com or .org, suggests visitors will feel comfortable typing in a card number or donating. Lower ratings, such as .info or .biz, come with notes about spam history. If you need a trust-heavy site such as a store or a membership service, favor extensions with higher trust and recognition scores, or add a strong brand to offset the weaker ending.

Type, best for and notes

The type tells you whether the extension is generic, a gTLD or a country code. The best-for line shows who usually picks it, and the notes flag special rules. For example, .app and .dev require HTTPS, so you need an SSL certificate from day one.

Which Domain Extension Is Best for SEO?

There is no single best extension for SEO, because Google's Search Central documentation says it treats new generic TLDs like .com and does not give them a ranking boost or penalty by themselves. Rankings come from content, links and user experience.

What the extension does change is click-through and memory. People are more likely to type .com from memory, and an odd ending can make a result look less trustworthy in a crowded results page. That is why the tool's ratings lean toward .com, .org and .net.

Country-code extensions have one more wrinkle. Google uses them as a geographic signal, so a .de domain suggests a German audience. Google's documentation lists a few country codes, including .io, .co and .me, as generic, so they are not treated as geo-targeted. If you serve one country, a matching country-code extension can help. If you serve the world, stick to a generic one.

Who Should Use a Domain Extension Comparison?

• Founders naming a startup who need to weigh a $12 .com against a $90 .ai.
• Freelancers and creatives choosing between .me, .studio, .design and .art for a portfolio.
• Store owners comparing .shop, .store and .com for an e-commerce brand.
• Non-profits and open-source projects that want the credibility of .org.
• Local businesses deciding between .com and a country code such as .us, .uk or .ca.
• Agencies shortlisting extensions for several clients and needing a quick pricing view.

Best Practices and Common Mistakes

Smart extension choices come from checking cost, trust and availability together. These habits prevent the most common regrets.

• Check the .com first. If you pick .io or .shop and a competitor owns the same name on .com, visitors may land on their site by mistake.
• Judge renewal, not just first-year, price. Multiply the price range by the number of years you plan to hold the name.
• Match the extension to your audience. A .dev domain suits a developer portfolio, but a family bakery will look odd on it.
• Avoid extensions with a spam reputation for trust-sensitive sites. The tool flags .info, .biz and .xyz for this reason.
• Keep the name short. A short, easy-to-spell name matters more than a clever extension.
• Consider protecting the brand. A second extension or common misspellings can stop lookalikes. The domain typo generator lists misspelled variations worth considering.

Troubleshooting

If no results appear, make sure at least one extension is ticked, then click Compare Extensions again. If the Register link is missing, you probably left the name field empty. If your name contains a dot or a space, remove it and use only the brand word, such as mybrand.

Limitations to Keep in Mind

The comparison is a decision aid, not a live price feed. Prices are typical ranges, so your registrar may charge more or less, and premium names (single dictionary words, for example) can cost far more than any listed range. The SEO, trust and recognition ratings are general guidance and do not measure how your own site will rank. The tool also does not confirm that a name is free until you follow the Register link and check it with the registrar. Some country-code extensions have residency or local-presence rules that a registrar will explain at checkout.

Next Steps After You Pick an Extension

Once you have a favorite, confirm the name is open with the bulk domain availability checker, which tests up to 20 names at once. If your first choice is taken, the TLD extension suggester turns one brand name into dozens of ideas, and the keyword domain finder helps you find names built around your topic. When you are weighing a name that is already registered, the domain age checker shows how long it has existed. If you move names later, the bulk domain transfer estimator helps you budget the change. You can find more utilities in the Domain Tools category.
