Is a .app Domain Good for Your Business? Meaning, HTTPS, and SEO

A .app domain is a strong choice for any software product, because it says exactly what you do in three letters and forces every visitor onto a secure HTTPS connection. Google Registry runs .app and added the whole extension to the browser HSTS preload list, so a .app site simply cannot load over plain HTTP. That built-in security is a small SEO plus, since Google uses HTTPS as a ranking signal, and it removes a class of setup mistakes. The tradeoffs are minor: you must have an SSL certificate in place before launch, and the ending suits software more than a general brand. Here is what .app means, what it costs, and who should use it.

.app domain facts at a glance

What does a .app domain mean?

A .app domain is a web address ending in .app, operated by Google Registry and aimed at software of every kind: mobile apps, web apps, SaaS products, and desktop tools. The meaning is right there in the name, so a visitor knows before they click that they are heading to a piece of software rather than a blog or a store. It launched to the public in 2018 and is open to anyone, with no requirement to prove you actually ship an app. For a product company, that clarity is the whole appeal: the extension does part of your positioning for you.

Why does a .app domain require HTTPS?

Every .app domain requires HTTPS because Google placed the entire extension on the browser HSTS preload list, so mainstream browsers refuse to connect to a .app site over insecure HTTP. There is no per-site setup to turn this on and no way to opt out; it is baked into the extension. In practice that means you must have a valid SSL certificate installed before your site will load for anyone. Most modern hosts issue a free certificate through Let's Encrypt automatically, so this is usually a non-issue, but it is the one thing to confirm before you launch on .app.

Is a .app domain good for SEO?

Yes, a .app domain ranks in Google like a .com, and its forced HTTPS gives it a small, real edge. Google has used HTTPS as a lightweight ranking signal since 2014, and because .app sites are secure by default, you never lose ground to a mixed-content or non-secure warning. The extension itself is treated as generic, so there is no penalty and no geographic tie. As with any domain, your rankings still come down to content, links, and page experience, but starting fully secure removes one common technical stumble.

How much does a .app domain cost?

A standard .app domain costs roughly 12 to 20 dollars a year to register and about the same to renew, which makes it one of the more affordable modern extensions, well under the 30 to 60 dollars a year that .io often runs. Short, one-word .app names may carry higher registry premium pricing, so check the exact figure before you buy. Because renewal sits close to the registration price, there is no surprise jump after the first year the way there is with dollar-promo extensions. See our domain cost guide to compare .app against other endings.

Is .app better than .io or .com?

It depends on your product and audience. A .com is still the broadest, most familiar default, so if the exact .com is available take it. Against .io, a .app is cheaper and states its purpose more plainly: .io reads as a developer or infrastructure product, while .app reads as a finished thing a user opens and uses. If you are shipping a consumer-facing or business app, .app often communicates better and costs less; if you are building developer tooling or an API, .io may still fit the culture. Compare the specific names available in each ending, since the perfect exact-match name usually matters more than the extension in the abstract.

How to set up a .app domain the right way

Setup on a .app is the same as any domain with one non-negotiable step: HTTPS has to work before launch. Point the domain's DNS at your host, then make sure a valid SSL certificate is issued for it, because a .app site will not load at all without one. On modern platforms like Vercel, Netlify, or Cloudflare Pages, the certificate is provisioned automatically within minutes of adding the domain, so there is nothing manual to do. On a traditional host, enable the free Let's Encrypt certificate in your control panel before you flip the site live. Test the URL in a fresh browser to confirm it resolves over HTTPS, then add your email records if you plan to send from the domain. Skipping the certificate is the single most common .app launch mistake, and it shows up as a site that simply will not open.

Who should use a .app domain?

A .app is a natural fit for SaaS companies, mobile and web app makers, and any product where the word app describes what you deliver. It works especially well as a product or download domain that sits alongside a company .com, for example a marketing site on the .com and the live product on the .app. Once you own the name, the next step is simply to stand up the site on it and point the domain at your host. It is a weaker pick for content brands, local services, or stores, where the app label does not describe the business.
