A wildcard SSL certificate uses a single certificate to secure multiple subdomains on the same website. For example, a website with subdomains www.example.com, blog.example.com, and mail.example.com could secure all those sub-domains with a single wildcard SSL for *.example.com. This provides an effective and affordable way to enable HTTPS across all subdomains, helping to build trust, maximize SEO potential, and avoid mixed content warnings.
Wildcard certificate secures all subdomains with HTTPS, using the padlock and “HTTPS” in the address bar to indicate a secure connection and build trust with users. Search engines give websites fully secured with HTTPS a slight SEO ranking boost, allowing all subdomains to qualify. Without an SSL, browsers may show “Mixed Content” warnings if some subdomains are http while others are https, so a wildcard certificate ensures all subdomains have consistent, secure https connections. Purchasing a wildcard SSL is also often more affordable than buying individual certificates for each subdomain.
A Wildcard SSL Certificate provides the HTTPS secure connection, padlock icon, and vouching by a trusted Certificate Authority that helps build trust with users. The certificate secures all subdomains, eliminating any insecure connections that could reduce trust and security. The consistent HTTPS experience across all URLs further enhances users’ trust in the website.
It is issued by a trusted Certificate Authority (Comodo, Sectigo, or Certera), which validates the website owner’s identity during the purchase and issuance process. The trusted Certificate Authority then acts as a vouching third party, giving users additional confidence that the website is legitimate.
Wildcard SSL uses a * (asterisk) as a wildcard character to represent any subdomain under a given domain, enabling it to encrypt HTTPS connections for an unlimited number of subdomains, securely connecting users to all parts of the website. The secure connection applies uniformly, ensuring no subdomain is left unprotected.
It provides a single point of management for all certificate needs across an entire domain and all its subdomains. When the certificate is installed on the website’s web server, it automatically secures connections to any subdomain under that top-level domain.
Without a wildcard certificate, a website would need to purchase individual SSL certificates for each subdomain. This can be more expensive and cumbersome to manage since a new certificate would be required whenever a new subdomain is added.
When a website uses a wildcard SSL to secure its domain and all subdomains with HTTPS, its URLs will all begin with ‘HTTPS’ instead of the insecure ‘HTTP.’ This indicates to users that a secure connection is in use.
For example, with a wildcard certificate for *.example.com, the URLs would be:
the browsers of visitors to those subdomains will display a locked padlock icon in the address bar. The lock icon indicates that the website has implemented HTTPS and an SSL certificate to encrypt the connection and thereby protect users’ privacy and data as they browse.

Wildcard SSL certificate can help avoid mixed content warnings and ensure that your website is fully secured with HTTPS. It improves the user experience & helps build trust with your visitors by providing a consistent and secure browsing experience across all subdomains of your website. By avoiding mixed content warnings, you can avoid potential SEO penalties and maintain your search engine rankings.
Using a Wildcard SSL with HTTPS can potentially have a positive impact on your website’s SEO rankings. As HTTPS is a ranking factor for search engines like Google/Bing. When a website uses HTTPS, it means that the data exchanged between the user’s browser & website server is encrypted. It is important because it helps protect sensitive information, such as login credentials or financial data, from being intercepted by hackers or other malicious actors.
Search engines like Google prioritize user experience and consider website security an important factor in this regard. Websites that use HTTPS are more likely to provide a safe & trustworthy experience for users, which can lead to higher levels of user engagement & satisfaction. This can translate into higher search engine rankings and improved visibility in search results.

Know the Advantages of Wildcard SSL Certificate.
Installing a Wildcard SSL will secure the domain name and all subdomains using the asterisk (*) symbol. For example, if you have a Wildcard SSL for *.example.com, it will secure blog.example.com, store.example.com, etc.
A Wildcard SSL certificate can help simplify certificate management and reduce costs by securing multiple subdomains with one certificate. It can also improve website security and user trust by providing a consistent and secure browsing experience across all subdomains.
One limitation of Wildcard SSL is that it can only secure subdomains on the same level as the domain name. For example, a Wildcard SSL for *.example.com cannot secure subdomains like sub.sub.example.com. Additionally, if one subdomain is compromised, it can potentially affect the security of all other subdomains.
To get a Wildcard SSL certificate, you will need to choose a reputable SSL provider, generate a Certificate Signing Request (CSR), and submit it to your provider along with any required documentation. Your provider will then verify your identity and issue the certificate.
The installation process for a Wildcard SSL will vary depending on your web server and operating system. Most SSL providers offer detailed instructions or support to help you through the process.
The lifespan of a Wildcard SSL certificate can vary depending on the provider and the specific certificate. Most Wildcard SSL is valid for 1-3 years, after which they will need to be renewed to maintain security and protection for your website and its visitors.
