Where to Buy Wildcard SSL Certificate

Explained What a Wildcard SSL is & How It Can Benefit Website

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.

Why a website needs a Wildcard SSL?

  • Security & Trust
  • Secure connection for all subdomains
  • Website URL starts with “HTTPS,” indicating security
  • The padlock icon in the address bar indicates trust
  • Avoids Mixed Content Warning

Security and Trust

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.

Secure Connection for all Sub-Domains

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.

Website URL starts with “HTTPS,” indicating security

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:

  • https://www.example.com
  • https://blog.example.com
  • https://mail.example.com

Padlock Icon in Address Bar Indicating Trust

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.

The Padlock indicates the following to Visitors

  • The identity of the website owner has been authenticated. The SSL certificate was issued by a trusted Certificate Authority, who confirmed the website owner’s identity during the issuance process.
  • The connection to the website is secure and encrypted, so users can trust that their data and communications are protected in transit.
  • The website takes security seriously and has tried implementing HTTPS to secure its users’ data and privacy.

Avoids Mixed Content Warning

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.

SEO Benefits of a Wildcard SSL Certificate

  • HTTPS can Boost your SEO rankings
  • Search Engines favor secure websites

HTTPS Can Boost Your SEO 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 favor secure websites

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.
