Setting up a custom domain and connecting it to your store: DNS records explained in detail

What does it mean to connect a domain to your e-commerce store?

A domain (or domain name) is the text address a visitor types into the browser to reach your store, like "mystore.com." The store itself runs on a server with a numeric address that is hard to remember. Connecting a domain to your e-commerce store means pointing that text address to the right server, so your store opens when someone types your name instead of the long default link your store provider gives you.

This pointing happens through the Domain Name System (DNS), which is like a phone directory that translates the text name into an address the browser understands. When you set up DNS records correctly, the browser knows where to find your store within seconds. A custom domain gives your store a professional look and more buyer trust, and makes it easier to remember in ads and links.

How do you buy a custom domain and pick the right extension?

The process starts by buying a domain from a domain registrar. Here are the practical steps in order:

1. 1Pick a short name that is easy to pronounce and type, and reflects your brand or product.
2. 2Check if the name is available using the search tool at the registrar, and try alternatives if it is taken.
3. 3Pick the right extension: ".com" is general and trusted, or business extensions like ".store" and ".shop", or a country code if your audience is local.
4. 4Complete the purchase and enable auto-renewal so you do not lose the domain when the term ends.
5. 5Enable privacy protection if available, to hide your personal information from public domain records.

What types of DNS domain records do you need to set up a store domain?

When you set up a store domain you will work with certain types of records, and each type has a different job. Your store provider gives you the exact values to enter, and the table below shows the main types and when you use them:

• In most cases you will add one A record for the root domain and one CNAME record for the "www" subdomain.
• Copy the values exactly as your store provider shows them, with no extra spaces or missing characters.
• An MX record is completely separate from displaying the store, so do not delete it if you use email on your domain.

What are the steps to connect a domain to your store using DNS records?

After you buy the domain and have the record values from your store dashboard, follow these steps in order:

1. 1Open domain settings in your store control panel, pick "Add custom domain", and type your domain.
2. 2The store will show you the DNS records you need (A record value and/or CNAME record value). Copy them exactly.
3. 3Log in to your domain registrar account and open the DNS record management page.
4. 4Add an A record and point it to the IP address your store gave you, then add a CNAME record for the "www" subdomain.
5. 5Delete any old conflicting records pointing the domain elsewhere, then save your changes.
6. 6Go back to your store dashboard and click "Verify" or "Connect" to confirm the connection succeeded.

Why is the domain connection incomplete without a security certificate (SSL)?

A security certificate (SSL) is what makes your store open via the "HTTPS" protocol with a lock icon in the address bar. Without it, a visitor sees a "not secure" warning, which drives buyers away and hurts trust before they even see your products. Most store platforms issue this certificate automatically and free as soon as DNS records point to the right server.

You usually do not need to buy the certificate manually; just make sure your records are right and wait for issuance to complete, then open your store via "https" to confirm the lock appears. If the warning stays after propagation is done, double-check your DNS record accuracy or request certificate issuance again from your store dashboard.

Checklist: How do you confirm your domain works correctly?

Before you launch your campaigns, run through this quick checklist to confirm your domain is fully connected to your store:

• The root domain "example.com" opens and shows your store directly without a long default link.
• The subdomain "www.example.com" opens and reaches the same store.
• The lock icon and "https" appear in the address bar with no security warning.
• Internal links and images load via your new domain, not the old one.
• Auto-renewal of the domain is enabled so the site does not go down later.
• You tested opening from a phone, another device, and a different network to confirm full propagation.

Where do you manage your store and prepare content after connecting your domain?

Once your domain works, you need a store to run and content to fill it. SymplysisAI gives you a built-in e-commerce store in every plan—the free plan starts with one store and up to 50 orders a month with no card required, and paid plans expand in store count and order limits (see the pricing page). The tools also generate Arabic landing pages, ad copy, posters, and voiceover from a single product link.

Before you launch cash on delivery campaigns, calculate your profit margin using the profit calculator at symplysis.com/calculator so you can price your products confidently once your domain is ready to receive visitors.
