The Importance of SSL Certificates: Keeping Data Secure & Boosting SEO


The Importance of SSL Certificates: Keeping Data Secure & Boosting SEO


SSL certificates are a crucial component of any website, enabling data encryption & secure connections. Beyond protecting user information, SSL certificates also provide SEO benefits by reassuring search engines that your site is trustworthy. 

In this guide, we’ll break down what SSL certificates are, their key benefits, types of certificates, implementation best practices & tips for leveraging SSL to improve search ranking. Gaining insight into SSL will help organisations secure sensitive communications & gain a competitive edge.

What is an SSL Certificate?

SSL stands for Secure Sockets Layer & is a protocol used to encrypt connections between a web server & browser. Installation of an SSL certificate enables HTTPS, which is the secure version of the HTTP protocol.

With HTTPS enabled, traffic between a website & visitors is encrypted through a Public Key Infrastructure (PKI). This protects data in transit from being read or modified by third parties.

SSL certificates validate a website’s identity & activate the browser padlock & green address bar that signals a secure connection. By establishing trust, SSL certificates help websites gain credibility with visitors & search engines.

The Benefits of an SSL Certificate 

SSL certificates provide two (2) core benefits:

Data Security

Encrypting connections protects sensitive user information like:

  • Login credentials
  • Personal details 
  • Financial & payment data
  • Any private communications

This prevents malicious parties from intercepting & stealing data during transit between a user & website. As threats like man-in-the-middle (MITM) attacks rise, encryption becomes critical.

Trust & Credibility 

Enabled SSL displays recognizable security indicators like the browser padlock & green address bar. This helps establish trust with visitors by signalling that a site is safe to share data with. 

For search engines, SSL helps verify legitimacy & can impact search ranking. Google especially emphasises SSL as a ranking factor for visibility & user experience.

Overall, SSL certificates demonstrate a commitment to security & trustworthiness that makes consumers more comfortable with providing personal details & drives conversions.

Types of SSL Certificates

There are three (3) main types of SSL certificates to consider:

Domain Validation (DV SSL) 

  • Validates control of a domain name only. 
  • No verification of business or identity.
  • The low-cost option is ideal for blogs & small sites. 

Organisation Validation (OV SSL)

  • Validates domain & legal business identity. 
  • Requires submission of documents.
  • Gives more identity assurance for visitors.

Extended Validation (EV SSL) 

  • The highest level of vetting for domain & business.
  • The legal business name is displayed prominently in the address bar. 
  • Indicates maximum credibility & trust.
  • Ideal for e-commerce, financial services & healthcare sites.

Choosing the right certificate type involves tradeoffs between cost, credibility & implementation time. But any SSL is better than no SSL when it comes to security & SEO.

Implementing an SSL Certificate

Follow these best practices when implementing SSL certificates:

  • Choose a credible provider: Only use trusted certificate authorities like Comodo, Symantec & Let’s Encrypt.
  • Pick the right certificate type: Choose based on your site goals & target audience. 
  • Enable HTTPS: Force HTTPS to redirect across all pages to maximise security.
  • Check compatibility: Ensure the certificate works with your server type, web host, CDNs, etc.
  • Include all subdomains: Wildcard SSL covers unlimited subdomains on one certificate.
  • Migrate content: Update any HTTP links internally or externally to use HTTPS versions.
  • Check renewal terms: SSL must be renewed every one (1) to three (3) years before expiration.
  • Monitor expiration: Set calendar reminders for renewal to prevent any lapses in security.

Proper planning during implementation ensures your website reaps the full benefits of an SSL certificate during its lifetime.

SSL Impacts on SEO & Search Ranking 

While not the sole ranking factor, SSL plays an important role in SEO due to its influence on: 

Security Signals: Google prioritises websites using encryption to protect visitors. HTTPS is a sign of trust & credibility.

Keyword Opportunities: HTTPS can appear in URLs, providing a keyword targeting opportunity, e.g. https://www.scriptonet.com

User Experience: Mixed content errors negatively impact user experience. SSL eliminates content warnings.

Page Speed: Encrypted pages often load faster due to Content Delivery Network (CDN) caching & other factors.

Link Building: More sites may link to pages protected by SSL to provide users with a secure destination.

While difficult to quantify, these factors likely provide a modest cumulative ranking benefit for sites using SSL certificates.

Tips for Leveraging SSL in SEO

Follow these tips to maximise the SEO value of SSL implementation:

  • Upgrade the entire site to HTTPS to avoid mixed content errors.
  • Redirect all HTTP pages to HTTPS to consolidate signals. 
  • Update old content & links referencing HTTP to use HTTPS instead.
  • Review analytics data since moving to HTTPS for any user experience impacts.
  • Build internal links using keywords in URLs to target.
  • Earn backlinks from trusted sites referencing HTTPS pages.
  • Host video & images on the site using HTTPS embed codes. 
  • Enable CDNs & caching to accelerate HTTPS site speeds.
  • Create content focused on website security & privacy protections gained through SSL.

Promoting your use of SSL certificates shows commitment to an optimal, secure user experience which search engines reward.


SSL certificates have become an essential component of modern web security & user trust. By encrypting data transmission between servers & browsers, they protect sensitive information from interception & manipulation. Beyond security, SSL certificates also play a crucial role in establishing credibility with users & search engines alike.

The benefits of implementing SSL extend far beyond basic encryption. They encompass improved search engine rankings, enhanced user trust & a commitment to best practices in web security. As cyber threats continue to evolve, having a robust SSL implementation is no longer optional – it’s a necessity for any website that values user privacy & aims to succeed in today’s digital landscape.

Whether you’re running a small blog or a large e-commerce platform, the right SSL certificate can make a significant difference in how your site is perceived by both visitors & search engines. By following the best practices outlined in this guide & staying informed about SSL developments, you can ensure that your website remains secure, trustworthy & well-positioned for success in the digital realm.

Remember, in the world of online security, staying proactive is key. Regularly review your SSL implementation, keep certificates up to date & continue to educate yourself on emerging security trends. By doing so, you’ll not only protect your users but also position your website for long-term growth & success in an increasingly security-conscious online environment.

Key Takeaways

To recap, key points to remember regarding the importance of SSL certificates include:

  • SSL enables site encryption through HTTPS to protect sensitive user data in transit.
  • Beyond security, SSL establishes trust & credibility which provides SEO benefits.
  • Certificate types range from low-cost domain validation to extensive extended validation.
  • Proper implementation requires technical planning & maintenance to maximise value.
  • SSL supports SEO through security signals, keywords, faster speeds & UX improvements. 
  • Leverage SSL by building secure links, promoting your certificate & creating related content.

By securing connections & demonstrating trustworthiness, SSL certificates provide the foundational layer for both safeguarding your visitors & elevating search visibility.

Frequently Asked Questions (FAQ)

What are the drawbacks of using a free SSL certificate?

Free certificates from providers like Let’s Encrypt offer domain validation only. They lack the extended trust indicators provided by paid organisational & extended validation certificates. If verifying identity is important for your business, a paid SSL option is preferable.

How much time duration does it take to obtain & install an SSL certificate? 

Implementation can take less than an hour for technically savvy users. Those less familiar may want to budget two (2) to four (4) hours for setup including testing. Your web host may also be able to install SSL certificates for you.

Do SSL certificates affect page load speed?

In the past, SSL slightly slowed page speeds but improvements in certificate issuance & browser technology have minimised that impact. CDNs & caching now often speed up encrypted sites instead.

Can I implement SSL on just my contact or payment pages?

While possible, it is best practice to implement SSL site-wide to maximise security & avoid mixed content warnings. A wildcard certificate covers the entire domain.

Does my SSL certificate need to match my domain name?

Yes, SSL certificates must use the exact domain name they are issued for. A certificate issued for www.site.com will cause errors on site.com. Use a wildcard or multiple certificates to cover variations.

What happens if my SSL certificate expires? 

An expired certificate will cause security warnings & errors. Set calendar reminders to renew your certificate every one (1) to three (3) years based on the provider term length to maintain a fully functional website.
