Did you know that using a single SSL certificate to secure multiple domains can save you time and money? If you’re managing several websites under different domain names, GoDaddy allows for the use of one SSL certificate across them all. This practice not only streamlines your security management but also ensures uniform protection across your online properties.

There are some essential factors and considerations to keep in mind. Understanding how this process works and its implications is crucial for maintaining a robust web security strategy. Let’s dive into the details of using a single SSL certificate across multiple domains on GoDaddy, including its benefits, limitations, and best practices.

SSL Certificates

Multi-Domain Security

SSL certificates, also known as Secure Sockets Layer certificates, play a crucial role in ensuring secure data transmission over the internet. They provide encryption for sensitive information, such as personal details and credit card numbers, making it extremely difficult for unauthorized parties to intercept and misuse this data. SSL certificates are essential for website security and trust since they establish an encrypted connection between a web server and a browser.

When you have multiple domains that need to be secured with SSL, using individual certificates for each domain can be costly and cumbersome. This is where multi-domain SSL certificates come into play. These types of certificates allow you to protect multiple domains with just one certificate, streamlining the process while providing robust security across all your websites.

GoDaddy Solutions

GoDaddy offers a solution that allows you to use one SSL certificate on multiple domains. Their multi-domain SSL certificates are designed to provide cost-effective security for various domains under a single certificate. For businesses managing multiple websites, this option not only simplifies the management of their SSL needs but also ensures that all their online properties benefit from robust encryption.

For example, if you own an e-commerce business with separate domains for different product categories or regions, using GoDaddy’s multi-domain SSL certificate can help you secure all these domains without the hassle of managing individual certificates for each domain separately.

Understanding SSL Certificates

Encryption Basics

SSL certificates are crucial for securing websites and ensuring the safety of data transmitted over the internet. GoDaddy offers multi-domain SSL certificates, which are perfect for businesses with diverse domain needs. These certificates provide comprehensive website security by encrypting data to prevent unauthorized access.

When you use one SSL certificate on multiple domains through GoDaddy, it means that all the domains covered by the certificate will have their data encrypted and secured. This is especially useful if you run multiple websites or have several subdomains that need protection.

For example, if you own a company with separate websites for different product lines, a multi-domain SSL certificate from GoDaddy can be used to secure each of these sites without needing individual certificates for each domain. This not only saves time but also reduces management complexity.

Certificate Types

SSL certificates work by using encryption to scramble data as it’s transmitted online, making it unreadable to anyone trying to intercept it without authorization. By doing so, encryption ensures both privacy and integrity in information exchange across websites.

Different types of SSL certificates cater to specific domain security requirements. For instance, single-domain SSL certificates are suitable when you need security for just one website or domain name. On the other hand, multi-domain SSL certificates are ideal if your business operates several related domains or subdomains that require protection under a single certificate.

In addition to this flexibility in covering multiple domains under one certificate, wildcard SSL certificates offer even broader coverage by allowing unlimited subdomains within a single top-level domain (TLD) to be secured under one certificate. This means that any new subdomains created within your TLD will automatically inherit the same level of security provided by the wildcard certificate.

Multi-Domain SSL Certificates


SSL certificates are like digital passports that authenticate the identity of a website and encrypt information sent to the server. They play a crucial role in securing online transactions, protecting sensitive data, and building trust with website visitors. By using one SSL certificate on multiple domains, businesses can streamline their security management and reduce costs associated with individual certificates for each domain.

Multi-domain SSL certificates, also known as Unified Communications Certificates (UCC) or Subject Alternative Name (SAN) certificates, allow organizations to secure multiple fully qualified domain names (FQDNs) under one certificate. This means that a single SSL certificate can cover several domains such as example.com, blog.example.com, example.net, etc. The flexibility offered by multi-domain SSL certificates is particularly useful for businesses managing numerous web properties.

Use Cases

Businesses operating across various domains or subdomains can benefit significantly from using one SSL certificate on multiple domains. For instance, e-commerce platforms handling different storefronts or payment gateways within the same infrastructure can effectively secure all these components with a single multi-domain SSL certificate. Similarly, marketing agencies managing websites for multiple clients under their umbrella find it efficient to use one comprehensive certificate instead of obtaining separate ones for each client’s domain.

Moreover, enterprises with diverse web properties catering to different regions or business units can simplify their security infrastructure by leveraging multi-domain SSL certificates. Whether it’s an international corporation maintaining country-specific websites or a conglomerate overseeing distinct brands under its portfolio, the ability to secure all these entities with one unified solution offers convenience and cost-effectiveness.

GoDaddy’s UCC SSL Certificates


Multi-domain SSL certificates are a cost-effective solution for securing multiple domains under a single certificate. However, they come with limitations on the number of domains they can secure. It’s important to understand these limitations before making any decisions about their usage. Some older browsers may not fully support certain encryption algorithms used in these certificates, so it’s crucial to consider compatibility issues.

Understanding the limitations of multi-domain SSL certificates is essential for making informed decisions about their usage. For example, if you have ten different domains that need to be secured, but your chosen multi-domain certificate only supports five domains, you’ll need to purchase an additional certificate or opt for a different solution altogether.


One of the key benefits of multi-domain SSL certificates is centralized management for diverse domains. They offer strong encryption and provide compatibility and trust indicators across all secured domains. This means that users will see consistent security indicators regardless of which domain within the certificate they’re visiting.

Moreover, features like SAN (Subject Alternative Name) support and unlimited server licensing enhance the utility of multi-domain SSL certificates, making them suitable for businesses or organizations managing numerous websites across various platforms and servers.


. They are compatible with popular web browsers, ensuring a consistent security experience for users visiting any domain covered by the certificate.

The seamless compatibility offered by multi-domain SSL certificates is crucial for widespread adoption and effective protection across multiple domains hosted on different servers or platforms.

Configuring UCC SSL for Multiple Domains

Domain Validation

When considering using one SSL certificate on multiple domains with GoDaddy, it’s essential to understand the pricing models. The cost varies based on the number of domains covered and additional features offered. By comparing costs, you can determine the most cost-effective solution for your multi-domain security needs. Understanding these pricing structures also aids in budget planning for SSL certificate investments.

The installation process is crucial when configuring a UCC (Unified Communications Certificate) SSL for multiple domains through GoDaddy. This involves validating ownership or control of each domain included in the multi-domain certificate. Different validation levels exist, such as domain validation (DV), organization validation (OV), and extended validation (EV). Each level offers varying degrees of authentication and verification processes.

Installation Process

Installing a single SSL certificate on multiple domains requires going through the specific steps provided by GoDaddy’s UCC SSL Certificate service. It involves verifying ownership or control over each domain included in the multi-domain setup. This process ensures that all listed domains are secured under a single certificate, simplifying management and maintenance tasks while providing robust security across various web properties.

Managing a UCC SSL for multiple domains entails overseeing all aspects related to its deployment and functionality across diverse websites or subdomains within an organization’s digital infrastructure. It allows centralized control over securing numerous online assets without having to manage individual certificates for each domain separately.

Wildcard SSL Certificates Explained


A wildcard SSL certificate is a type of digital certificate that allows you to secure a main domain and all its subdomains with a single certificate. This means that if you have multiple subdomains under one main domain, you can use the same wildcard SSL certificate to secure them all. For example, if you have “example.com” as your main domain and subdomains like “blog.example.com,” “shop.example.com,” and so on, a wildcard SSL certificate would cover them all.

Wildcard SSL certificates are cost-effective because instead of purchasing separate SSL certificates for each subdomain, you only need one wildcard certificate to secure them all. It simplifies the management of your website’s security by reducing the number of certificates needed.

Another advantage is that it provides consistent encryption across all subdomains, ensuring uniform security standards throughout your website.

Subdomain Coverage

Using a single wildcard SSL certificate on multiple domains in GoDaddy has its limitations. While it secures unlimited first-level subdomains (e.g., *.example.com), it does not cover second-level or subsequent subdomains (e.g., ..example.com). Therefore, if your requirement includes securing an extensive range of unique second-level or third-level subdomains across various domains, this type of wildcard SSL might not be suitable for your needs.

However, for scenarios where the primary concern is securing numerous first-level subdomains under one main domain without needing individual certificates for each one separately, a wildcard SSL from GoDaddy could be an efficient solution.

Server Use

In terms of server use, when implementing a single wildcard SSL certificate on multiple domains in GoDaddy hosting environments such as Apache or Nginx servers, configuration adjustments may be necessary. These adjustments involve installing the wildcard SSL at the server level and updating virtual host configurations to ensure proper encryption for each applicable subdomain within the covered domain scope.

For instance:

In Apache servers: The VirtualHost directive should include ServerName and ServerAlias entries matching both the main domain and its associated first-level wildcards.

Comparing UCC and Wildcard SSL Certificates


Both UCC (Unified Communications Certificate) and Wildcard SSL certificates are types of SSL certificates that offer secure connections for multiple domains. They both provide encryption for data transmitted between a website and its visitors, ensuring that sensitive information remains private.

UCC and Wildcard SSL certificates also support the use of Subject Alternative Names (SANs), which means they can secure multiple domain names with just one certificate. For example, if you have a domain like www.example.com and another like mail.example.com, both can be secured using either a UCC or Wildcard SSL certificate.

In addition to securing multiple domains under one certificate, these two types of certificates also help in reducing administrative tasks because you only need to manage one certificate instead of individual ones for each domain. This makes it easier to keep track of expiration dates and renewals.


The key difference between UCC and Wildcard SSL certificates lies in their scope of coverage. A UCC is specifically designed to secure Microsoft Exchange Server communications, including Outlook Web Access (OWA), ActiveSync, Autodiscover services, as well as Unified Messaging. On the other hand, a Wildcard SSL certificate is more versatile as it secures the main domain along with an unlimited number of subdomains.

Another notable difference is cost-effectiveness based on specific requirements. If your primary goal is to secure multiple subdomains under the same base domain name such as blog.example.com, shop.example.com etc., then a Wildcard SSL might be more cost-effective compared to purchasing separate UCCs for each subdomain.

When considering compatibility across different server types or platforms beyond Microsoft Exchange Server environments, choosing between these two options becomes crucial. While UCCs are tailored towards Microsoft products’ needs due to their SAN feature support that meets those requirements efficiently; however, if your organization’s infrastructure extends beyond this ecosystem or may do so in the future – opting for a more flexible solution like a Wildcard SSL would be advisable.

This can lead to an improvement in your search engine rankings, as Google has officially stated that HTTPS is a ranking factor. With higher visibility in search results, you have the potential to attract more organic traffic to your websites.

Furthermore, having one SSL certificate for multiple domains simplifies the management of security certificates. It reduces the risk of overlooking any domain when renewing or managing certificates individually. This centralized approach not only saves time but also ensures that all domains remain protected without any gaps in security coverage.

User Trust

Using a single SSL certificate for multiple domains enhances user trust and confidence in your websites. When visitors see the padlock icon and “https” in their browser’s address bar across all of your domains, it reassures them that their data is encrypted and secure during interactions with your sites. Users are increasingly cautious about sharing personal information online, so providing a consistent level of security across all domains can help alleviate their concerns.

Moreover, displaying SSL certificates on every domain creates a professional image for your brand. It demonstrates that you prioritize the protection of user data and are committed to maintaining high-security standards across all web properties associated with your business.

Conversion Rates

The use of one SSL certificate on multiple domains can contribute to improved conversion rates by fostering trust among visitors and customers. When people feel confident about the security measures implemented on each domain they visit within your network, they are more likely to proceed with transactions or other desired actions on those sites.

For instance, if you operate an e-commerce business selling products through different subdomains or country-specific domains under one main domain name (e.g., us.yourdomain.com), using a single SSL certificate ensures uniform encryption throughout these various sections of your online store. This consistency reinforces customer trust during the entire shopping experience regardless of which specific domain they interact with.

Common Misconceptions About SSL and Domains

Single Domain Myths

Many people wonder, “Can I use one SSL certificate on multiple domains GoDaddy?” There is a common misconception that a single SSL certificate can be used to secure multiple domains. However, it’s important to understand that a standard SSL certificate is typically issued to secure only one domain or subdomain. While some providers offer multi-domain certificates, they come with specific limitations and are often more expensive.

It’s crucial to note that using a single SSL certificate for multiple domains may lead to security vulnerabilities. Each domain has its own unique set of security requirements, and using the same certificate across all of them could compromise the overall security of your websites. If one of the domains experiences an issue or needs to be removed from the certificate, it could impact the security of other linked domains.

In essence, while it might seem convenient to use one SSL certificate for multiple domains, it’s essential to prioritize individualized security measures for each domain rather than attempting to consolidate them under a single certificate.

Security Overheads

Another misconception surrounding SSL certificates and multiple domains involves concerns about potential security overheads.

When managing the certificates for multiple domains, ensure that all the domains are added correctly in the SAN field during the initial setup. This step ensures that each domain is covered by the same SSL certificate without any issues.

It’s important to note that while using one SSL certificate for multiple domains can be convenient and cost-effective, it requires careful management to ensure all included domains remain secure and properly configured.

Renewing an SSLcertificate covering multiple domains involves considering various renewal strategies. With GoDaddy, you may opt for either individual renewals or a single renewal for all included domains under the multi-domain SSL certificate.

One strategy involves setting up auto-renewal for your multi-domain SSL certificates. This feature helps prevent any unintentional lapses in coverage across your various domain names.

Another strategy is aligning the expiration dates of all included domain names within your multi-domain SSL certification. By doing so, you streamline the renewal process and minimize potential gaps in security coverage across your websites.

Using one SSLcertificate on multiple Godaddy-hosted domains should not compromise security protocols if managed correctly. However, it’s important to consider certain security protocols such as ensuring strong encryption standards across all hosted sites.

Moreover, maintaining updated versions of TLS/SSL protocols is essential for securing connections between clients and servers across different hosted domain names under a single SSL certification from GoDaddy.

Implementing best practices like regular vulnerability assessments and staying informed about emerging threats will help maintain robust security measures across all covered domain names.


It’s essential to consider the convenience and cost-effectiveness of this approach. While it may seem like a practical solution, there are certain limitations and considerations that need to be taken into account before making a decision.

One of the key factors to keep in mind is the compatibility of a single SSL certificate with multiple domains. In some cases, you may encounter restrictions based on the type of SSL certificate you have purchased. For instance, a standard SSL certificate typically secures only one domain or subdomain. However, if you opt for a wildcard or multi-domain (SAN) SSL certificate, you can secure multiple domains under a single certificate.

Another important consideration is managing and renewing the SSL certificate for multiple domains. While using one SSL certificate for several domains simplifies management by having all your security needs in one place, renewal processes need careful attention. If the certificates expire at different times or require varied validation processes due to domain ownership changes, managing them can become complex.
