# Website URL — subdomain

Your Bulido website has its own URL in the format `name.bulido.com` (or `.bulido.pl` / `.bulido.de` for the Polish and German markets — the suffix matches the dashboard you logged into). That's the link you put on a business card, send a client by SMS, or share on Facebook.

## How to pick a subdomain

The subdomain is the part of the URL before the `.bulido.<tld>` suffix.

On wizard **step 3** you'll see up to five **suggested addresses** chips below the input — derived from your company name, first name and surname (e.g. for "Jan Kowalski" at "Acme Painting": `acme-painting`, `jan-kowalski`, `jan`, `acme-painting-jan`). Each suggestion is pre-checked as free. Tap one to fill the field, or type your own.

Rules:

- **Lowercase letters, digits and hyphens only** — no spaces, accented characters, capital letters.
- **3 to 30 characters**.
- **Cannot start or end with a hyphen**.
- **Cannot be a reserved word** (e.g. `admin`, `api`, `login`, `www`, `mail`, `user` — Bulido shows a message if you pick one, and they never appear in the suggestion chips).
- **Must be free** — Bulido checks in real time whether someone else has it.

## Good practices

- **Short**. Clients type this manually. `jb-renovations.bulido.com` is better than `johnbuilderrenovationsfullservice.bulido.com`.
- **Readable**. Make it clear what it is. `finishings-london.bulido.com` says more than `account123.bulido.com`.
- **Tied to your brand**. If you already have a logo, leaflets, or email signature — make the URL match what they say.

## How to change it

In **Settings → Website**, **SEO** tab — the **Subdomain** section is at the top of that tab. Type the new URL, Bulido checks if it's free. If yes, the global save bar at the bottom of the panel shows the unsaved change; click **Save changes** and confirm in the dialog.

## ⚠️ What happens to the old URL after a change

**The old URL stops working IMMEDIATELY.** There is no redirect.

That means: any client with the old link saved (in email, contacts, on a leaflet) will hit a "not found" page. The old URL also becomes free — someone else can take it.

So:

- Change the subdomain **only if you really have to**, don't experiment.
- After the change, **update everywhere** you list the URL: business card, email signature, Google/Facebook profile, leaflets.
- If you're not sure — leave the current URL.
