Optimizing Your Website's SEO with CNAME Records
What is "C-name" in web hosting?
In web hosting, "CNAME" stands for "Canonical Name."
- It is a type of DNS (Domain Name System) record to create an alias or nickname for one domain name to another.
- A CNAME record allows you to map one domain (or subdomain) to another realm.
- For example, let's say you have two domains: "example.com" and "www.example.com."
- Instead of setting up separate DNS records for each element, you can create a CNAME record that points "www.example.com" to "example.com."
- This way, when someone types "www.example.com" in their web browser, it can resolve to the IP address associated with "example.com."
- CNAME records are frequently employed to create subdomains, offer alternative names for current resources, or streamline DNS settings within a single website or service.
- It's important to note that CNAME records can only point to other domain names and not directly to IP addresses.
- If you need to map a domain directly to an IP address, use an "A" (Address) record instead of a CNAME.

How does a CNAME record help in Google ranking?
- Canonicalization: CNAME records assist in canonicalization by allowing you to set a preferred domain for your website. This process helps Google understand the primary realm you want to use and avoid duplicate content issues.
- Subdomain Usage: Creating subdomains with CNAME records can help organize content and improve user experience, indirectly impacting ranking by making it easier for visitors to navigate your site.
- Load Distribution: CNAME records enable the distribution of web traffic across multiple servers or CDNs, thereby improving website performance and load times. This process enhances rankings in search results, as Google search engines often prefer faster websites.
- SSL Certificates: CNAME records enable a single SSL certificate across multiple subdomains, which can positively influence ranking by ensuring a secure browsing experience for users.
- Site Migration: During website migration, CNAME records can redirect traffic from the old domain to the new one, preserving search engine rankings and preventing traffic loss.
- Content Delivery Networks (CDNs): CNAME records allow CDNs integration, can speed up content delivery and positively impact SEO by improving page load times.
- Flexible Domain Management: With CNAME records, you can switch hosting providers or change the IP address of a domain without affecting its DNS settings, providing more flexibility for maintaining the website's ranking during infrastructure changes.
How to add CNAME records in Blogspot or Bloggers?
To add CNAME records in Blogspot (also known as Blogger), you'll need to follow these steps:
- Sign in to your Blogger Account: Go to www.blogger.com and sign in with your Google account associated with your Blogger blog.
- Access your Blog's Settings: Once logged in, click on the "Settings" option for the blog where you want to add the CNAME record.
- Go to the "Basic" Section: In the left sidebar, click on "Basic" under the "Settings" section.
- Set up a Custom Domain: Scroll down to the "Publishing" section. You should see your current blog address, which typically looks like "yourblogname.blogspot.com." Click the "Set up a third-party URL for your blog" link.
- Enter your Custom Domain: Enter the custom domain name you've purchased (e.g., www.yourdomain.com) into the text box provided. Confirm you've already purchased the domain from a domain registrar and configured its DNS settings to point to your Blogspot blog.
- Add CNAME Records: After entering your custom domain, Blogger will provide you with two CNAME records. You can add these records to your domain's DNS settings through your domain registrar or hosting provider. The CNAME records are typically in the format of "www" and "ghs.google.com".
- Configure DNS Settings with your Domain Registrar: Log in to your domain registrar's website (where you purchased the custom domain). Look for the DNS management or DNS settings section. Find the option to add/edit DNS records.
- Add the CNAME Records: Add the two CNAME records provided by Blogger. One will be for the "www" subdomain and the other for the "ghs.google.com" target.
- Save the Changes: Save the changes you made to the DNS settings. The changes may take some time to propagate across the internet.
- Complete the Custom Domain Setup: Revert to your Blogger settings, enter your custom domain again, and click the "Save" button. If everything is correct, Blogger will confirm the successful setup of your custom domain.
Please note that DNS changes may take some time to propagate, so your custom domain might not be immediately available. Additionally, some domain registrars have different interfaces for managing DNS settings, but the basic steps to add CNAME records are similar across various or diverse providers. If you encounter any difficulties, refer to your domain registrar's documentation or contact their support for assistance.
How can bloggers detect the changes?
After setting up a custom domain in Blogger and adding the necessary CNAME records, bloggers can detect the changes by following these steps:
- Check Domain Settings in Blogger: Log in to your Blogger account and navigate to the blog where you set up the custom domain. Go to the "Settings" > "Basic" section and check the "Publishing" section. Here, you should see the custom domain you entered earlier.
- Verify Domain Ownership: Blogger might prompt you to verify domain ownership to ensure that you have access to the domain's DNS settings. Follow the verification steps provided by Blogger, which typically involve adding a TXT or CNAME record to your domain's DNS settings.
- Wait for DNS Propagation: DNS changes can take time to propagate across the internet. This process can vary but typically takes a few minutes to a few hours. Occasionally might take up to 48 hours for the changes to fully propagate. During this time, the custom domain might not be accessible, or you might see the old realm.
- Check Custom Domain Availability: Once the DNS changes have fully propagated, you can try accessing your blog using the custom domain (e.g., www.yourdomain.com). If everything is correct, your blog should be accessible through the custom domain.
- Verify Redirects (Optional): If you set up 301 redirects from the old domain (e.g., yourblogname.blogspot.com) to the custom domain, check if the redirects are working as expected. The original realm should automatically redirect visitors to the new custom domain when they access it.
- Test Functionality: After the custom domain is accessible, click through various pages and posts on your blog to ensure that all functionality, links, and images are working correctly.
- Check SSL Certificate (Optional): If you have set up SSL for your custom domain, confirm your website is loading securely with "https://" and a padlock symbol in the browser address bar.
- Clear Browser Cache (If Needed): If you still encounter issues, try clearing your browser cache and cookies. Sometimes, cached data can prevent you from seeing the updated version of your website.
- Check with Different Devices and Networks: Verify your custom domain's functionality using different devices (e.g., computer, smartphone, tablet) and from various internet networks. This process helps ensure that the changes are visible to all users.
By following these steps, bloggers can confirm that the changes, including the CNAME records and custom domain setup, have been successfully implemented and are visible to visitors. Bloggers should double-check the DNS settings with the domain registrar and verify the CNAME records if any issues arise.
