Propagation Time

Once a subdomain has been created, it can take anywhere from a few minutes to up to 48 hours for it to become available on the web. This duration is called propagation time and is caused by the time it takes for changes to propagate to all of the DNS servers worldwide. The number of DNS servers, the geographic distance between them, and the performance of the DNS servers all influence the propagation time. Additionally, if the primary domain has not been configured with the correct name servers, it can take even longer for the subdomain to propagate.

How can I make a subdomain faster?

1. Choose the Right Hosting Provider

Choosing the right hosting provider is the most important step in making a subdomain faster. Look for a hosting provider that is reliable, offers high-speed servers, and provides high levels of security. Also, consider their customer service and how often they upgrade their systems. With the right hosting provider, your subdomain should be able to handle high traffic without any problems.

2. Minimize HTTP Requests

Reducing the number of HTTP requests can significantly improve the speed of your subdomain. To minimize HTTP requests, you should minimize the number of files on your page. This can be done by removing unnecessary elements such as background images, scripts, and CSS files. Additionally, you should combine multiple files into one file whenever possible.

3. Utilize a Content Delivery Network (CDN)

A content delivery network (CDN) can significantly reduce the loading time of your subdomain. A CDN works by caching your content on multiple servers located around the world. This allows users to access your content from the closest server, which reduces latency and loading times.

4. Optimize Images

Large images can significantly increase the loading time of your subdomain. To optimize your images, you should reduce their file size as much as possible without sacrificing quality. You can also use the right image format for the job, such as JPEG for photos and PNG for graphics.

5. Enable Browser Caching

Enabling browser caching can help reduce the loading time of your subdomain. Browser caching stores certain elements of your website on the user’s computer, which allows the content to be loaded more quickly on subsequent visits. To enable browser caching, you can use a caching plugin or edit your .htaccess file.

Why subdomain is not good for SEO?

Why Subdomains are Not Good for SEO?

1. Low Authority: Search engines view subdomains as separate entities from the main domain, so each subdomain will have to be manually optimized in order for it to be indexed properly. Additionally, due to the lack of trust and authority associated with the main domain, the subdomains may suffer from low search engine rankings and less visibility.

2. Duplicate Content: Most websites use subdomains to host different sections, such as a blog, ecommerce store, or forums. However, if the content from these sections is duplicated on the main domain, then it can lead to duplicate content issues and a decrease in organic rankings.

3. Difficult to Track: It can be difficult to track the performance of a subdomain in comparison to the main domain. This makes it difficult to measure the success of the subdomain and make changes or optimizations as necessary.

4. Not Search Engine Friendly: Subdomains have to be individually optimized in order to be indexed properly, which can be a time-consuming process. Additionally, while they can be indexed, they may not be given as much priority as the main domain.

An A record can also be used to point a subdomain to a separate IP address.
