How to connect your .com.mx domain to your website (step by step)

You’ve already got your page published and you’ve already bought your .com.mx. Now comes the part that scares everyone: how to connect your .com.mx domain to your website so that when someone types tunegocio.com.mx, your site shows up instead of a blank screen. It sounds like a job for programmers, but it isn’t. It’s two pieces of data you copy and paste, and a wait. That’s it.

We’re not going to debate here whether it’s worth having your own domain or which one to buy — we covered that in another post. This one assumes you’ve already bought it and just want it to work. Let’s go step by step, with a real example so you don’t get lost: Florería Girasol, in Querétaro, already has its page built on Proyecta and just bought floreriagirasol.com.mx. All that’s left is connecting it. Let’s do it together.

What is a DNS record?

DNS is the internet’s address book: when someone types floreriagirasol.com.mx, their phone asks “where do I send this person?”, and the address book answers with an address. Connecting your domain is, literally, writing that address in the book. That’s all you’re going to do — you’re not going to program anything.

You’ll use two types of records, and with these you’re set:

A record — tells where to send your “bare” domain, the one with nothing in front: floreriagirasol.com.mx.
CNAME record — tells where to send the www version: www.floreriagirasol.com.mx.

You don’t need to fully understand them. You just need to know they’re two lines you’re going to copy from one place and paste into another.

Step 1: get the data Proyecta gives you

Go to your page in Proyecta, open the domain settings, and enter the one you bought (floreriagirasol.com.mx). Proyecta will show you on screen the exact data you need to copy: the A record value and the CNAME value. Don’t make them up or copy them from a YouTube tutorial — use the ones Proyecta shows you, because those are the ones pointing to your page, not someone else’s.

Leave that window open, or copy them to a note on your phone. You’ll paste them in a moment.

Step 2: go to your registrar’s panel

The “registrar” is where you bought the domain: Akky, GoDaddy, NIC México, Namecheap, whichever one you used. Log into your account and look for the section called “DNS”, “Manage DNS zone”, or “Edit records”. Every panel looks different, but they all have that section; if you don’t see it, look under the domain’s settings, not the account’s.

That’s where your domain’s address book lives. And watch out for one thing: it almost always comes with records already set by default — an “under construction” page or a redirect from the registrar itself. Those are the ones that are going to clash with your new page, so make a mental note of them because you’re about to change them.

Step 3: connect your domain (paste the two records)

Now for the important part. In that DNS section:

Find the A record for the bare domain (sometimes it shows up as the record named @). Delete it or edit it, and enter the address Proyecta gave you.
Find or create the CNAME record for www and set it to the value Proyecta gave you.

Save. That’s it: two lines. If your registrar asks you for a “TTL,” leave it as is or set it to the lowest one offered — that only changes how fast the address book updates.

A classic mistake here is leaving the registrar’s old record alongside the new one. The two can’t coexist: if you leave the default redirect next to your A record, your domain will work “sometimes yes, sometimes no.” Leave only what Proyecta gave you.

How long does it take to connect a .com.mx domain?

It can take anywhere from five minutes to a full day, though a few hours is most common. It’s called propagation: the time it takes for your change to spread across the whole internet, and there’s no button to speed it up.

You saved everything, you type floreriagirasol.com.mx into the browser… and you get an error or the old page shows up. You didn’t do anything wrong. That’s just how it goes while propagation is happening. If you want to check on its progress, type your domain into one of those “dnschecker” tools and it’ll tell you which countries have already updated.

The rule is simple: if you already pasted both records correctly, don’t touch anything else. People mess up their connection because they get impatient after ten minutes, think they made a mistake, start changing things, and that’s when they actually break it. Paste them, close the laptop, and check back in a while.

Do you need to buy an SSL for your .com.mx domain?

No. In Proyecta, the security certificate —the 🔒 lock next to https://— is generated automatically as soon as your domain is pointing correctly; you don’t need to buy it separately or pay anyone for it.

When your page loads on the new domain, check that it shows https:// with the lock closed at the top. If you see a “not secure” warning at first, it’s almost always because the domain is still finishing propagation (the previous step). Give it a bit more time and it’ll sort itself out.

What are the most common mistakes when connecting a .com.mx domain?

There are three, and they come up in almost every case:

Pasting the record in the wrong field — the A record value goes in the A field, the CNAME value goes in the CNAME field. Mix them up and it won’t work.
Typing the domain with www in one place and without it in another — that’s exactly why you set up both records, the bare one and the www one. With both in place, it works no matter how it’s typed.
Giving up after ten minutes — propagation takes time. Be patient.

What if you don’t have the page yet?

If you ended up here looking for how to connect your domain but the page doesn’t exist yet, do it the other way around and save yourself the stress: first describe your business in Proyecta —“a page for my flower shop with an arrangement catalog, photos, and a WhatsApp button”— and publish it. It goes live immediately with a link you can already share, even if it’s the temporary one. You can connect your own domain later, with these same five steps, whenever you have it. You don’t need the .com.mx to start selling; you need it to look more official, and that can wait a few days.

Describe it, publish it, and keep the link (proyecta.dev). When your domain arrives, you’ll know exactly what to do.
