One domain for everything you sell: your website, payments, and WhatsApp, without any overlap
Knows how to add a new service (an online store, a WhatsApp number, a payment button, a different language, a sister brand) to the same domain that already has a working website and email, without breaking either one. Ends with a written map of which record serves what, so you never have to touch DNS blind again.
Your website already works: email arrives, the domain is verified, everything's in place. Now you want to add something (an online store, a WhatsApp number, a payment button, the English version, or a sister brand), and you're not sure if it piggybacks on what you already have or needs its own corner. Touching DNS blind is scary: one wrong record and email goes down or the domain stops verifying.
This course solves that in the order the problems actually show up. First, the rule for choosing between a folder and a subdomain. Then, how to create that subdomain without dragging along anything from the old one. Next, which records you shouldn't touch when you add WhatsApp or payments, and what to do if Meta or your payment gateway asks you to verify one, so you don't break your email. From there, the difference between a new language and a new brand. It wraps up with a written map of every record, so you never have to improvise again.
This is for business owners who already have a website and email working with their own domain and are about to add something new to it. It's not for someone who doesn't have a domain yet, since this starts from one that's already working.
- Deciding whether the new thing goes in a folder of your website or in a separate subdomain.
- Creating the subdomain without touching the records for the email or website you already have running.
- Knowing which DNS records you shouldn't touch when you add something new, so you don't break the email or the website that already work.
- Writing out a map of your DNS, record by record, so you never have to touch it blindly again.
Have your business website and email already working on your own domain, and have access to its DNS on hand (wherever you bought it or wherever it's hosted).
The 6 lessons
In the order it makes the most sense to read them.
- 1
The new addition: under your website, or next to it?
You know how to decide, with a real criterion instead of a guess, whether the new addition to your business goes in a folder of your website or in a separate subdomain.
7 min - 2
The new subdomain doesn't inherit anything from the old setup
After this lesson, you'll have the subdomain record created as a new row, know which DNS rows should never be touched in this step, and have confirmed that the website and email that were already working still respond the same way.
7 min - 3
If Meta asks you to verify your domain
You'll come away knowing how to add the TXT record Meta uses to confirm your domain is yours without touching your email's SPF, and how to check from outside that both records coexist.
6 min - 4
The payment button lives on your website, and it almost never requires touching the domain.
You'll know whether your payment button needs anything on your domain, and if it does, you'll add it without overwriting what you already had in the DNS.
8 min - 5
The language hangs off your domain, a new brand doesn't
That you decide whether the new addition shares your domain or needs its own by checking whether it has its own brand name, not whether it's a different language.
5 min - 6
The map you'll never have to improvise again
By the end, you'll have written down, line by line, what each DNS record is for, so you never touch it blindly again.
