Why an SSL Certificate Matters for SEO

What is an SSL certificate

An SSL (Secure Sockets Layer) certificate is a digital certificate that encrypts communication between the user's browser and your web server. When a site has an SSL certificate, the URL starts with "https://" instead of "http://", and the browser shows a padlock icon next to the address.

Without SSL, all data sent between the user and the server (passwords, personal data, card numbers) travels as plain text and can be intercepted by attackers. With SSL, that data is encrypted and practically unreadable to anyone trying to intercept it.

SSL as a Google ranking factor

Google officially announced in 2014 that HTTPS is a ranking signal. The importance of HTTPS has only grown since, and today it is practically impossible to rank on Google's first page without an SSL certificate.

How SSL affects SEO

• Direct ranking signal: Google explicitly lists HTTPS as one of the ranking factors. Two identical sites - one with and one without SSL - the SSL site will rank higher.
• Referral data: When a user moves from an HTTPS site to an HTTP site, referral data is lost in Google Analytics. The traffic is shown as "direct" instead of as referral, which makes source analysis harder.
• Core Web Vitals: An HTTPS site can use HTTP/2 and HTTP/3 protocols that significantly speed up loading. HTTP/2 requires an SSL certificate. A faster site = better Core Web Vitals = better ranking.
• Indexing: Google prefers to index the HTTPS version. If you have both HTTP and HTTPS versions, Google will pick HTTPS as canonical.

Chrome warnings and user trust

Since 2018, Google Chrome marks all HTTP sites as "Not Secure" in the address bar. This warning is visible to every visitor and directly affects trust and conversion.

Impact on user behavior

• Bounce rate: Studies show 84% of users leave a site if they see a "Not Secure" warning. For e-commerce sites the effect is even stronger.
• Conversion: Sites that moved from HTTP to HTTPS record on average a 10-15% conversion increase, solely thanks to increased user trust.
• Form filling: Chrome specifically warns users when trying to enter data in forms on an HTTP site. Many users will abandon a contact form or purchase.

Besides Chrome, Firefox, Edge, and Safari also show warnings for HTTP sites. In 2026, a site without SSL looks unprofessional and unsafe, regardless of content quality.

SSL certificate types

There are different SSL certificate types that differ in validation level, number of covered domains, and price.

By validation level

• DV (Domain Validation): The simplest type - only confirms you control the domain. Issued automatically within minutes. Free via Let's Encrypt or included in a hosting plan. Enough for most sites.
• OV (Organization Validation): Confirms the identity of the organization behind the domain. Requires company verification (registration number, address). Provides higher trust. From $50/year.
• EV (Extended Validation): The strictest validation - more detailed company, legal status, and physical address checks. It used to show the company name in a green browser bar, but most browsers have removed that visual distinction. From $200/year.

By number of domains

• Single domain: Covers only one domain (e.g. beohosting.com). The cheapest type.
• Wildcard: Covers the domain and all subdomains (*.beohosting.com - mail.beohosting.com, shop.beohosting.com, etc.). Ideal if you have multiple subdomains.
• Multi-domain (SAN): Covers multiple different domains on one certificate. Ideal for companies with multiple sites.

HTTPS implementation

Migrating from HTTP to HTTPS requires careful implementation to avoid losing SEO value or creating technical issues.

Step by step

• 1. Install the SSL certificate: On BeoHosting, free Let's Encrypt SSL can be activated in cPanel with one click in the "SSL/TLS Status" section.
• 2. Redirect HTTP to HTTPS: Set up a 301 redirect from all HTTP URLs to HTTPS versions. Add rules to .htaccess or use "Force HTTPS Redirect" in cPanel.
• 3. Update internal links: Change all internal links from http:// to https://. In WordPress, use the Better Search Replace plugin for bulk replacement.
• 4. Update mixed content: Verify that all images, scripts, and styles also use HTTPS. Mixed content can block resource loading and show browser warnings.
• 5. Update Google Search Console: Add the HTTPS version of the site as a new property in Google Search Console and resubmit the sitemap.
• 6. Update Google Analytics: Change the default URL to HTTPS in Admin > Property Settings.
• 7. Update external links: Contact sites linking to you and ask them to update links to the HTTPS version. A 301 redirect will transfer SEO value, but a direct HTTPS link is better.

Common implementation mistakes

• Mixed content: The page loads over HTTPS but contains resources (images, scripts) loaded over HTTP. The browser will either block them or show a warning. Use a tool like Why No Padlock to identify mixed content.
• Missing redirect: If you do not set a 301 redirect from HTTP to HTTPS, Google will see two versions of the site, which can lead to duplicate content and wasted SEO value.
• Expired certificate: An SSL certificate has an expiration date (usually 90 days for Let's Encrypt, 1 year for commercial). If it expires, the site shows a scary warning. Set up automatic renewal.
• Redirect loops: Wrong .htaccess or CDN configuration can create infinite redirect loops (ERR_TOO_MANY_REDIRECTS). Test the configuration carefully.
• Canonical tags: Verify that canonical tags on all pages point to the HTTPS version of the URL.

SSL and performance

A common myth is that SSL slows down the site. That was partly true 10 years ago, but today the situation is reversed - an HTTPS site can be faster than an HTTP site.

• HTTP/2: This protocol significantly speeds up page loading via multiplexing, header compression, and server push. HTTP/2 requires an SSL certificate - without it, the site stays on slower HTTP/1.1.
• HTTP/3 (QUIC): The latest protocol that further reduces latency. Also requires HTTPS.
• TLS 1.3: The latest TLS version reduces the handshake to a single roundtrip (TLS 1.2 requires two). The load difference is minimal - less than 10ms.
• OCSP Stapling: Instead of the browser contacting the Certificate Authority for verification, the server "staples" the OCSP response to the certificate. LiteSpeed automatically supports OCSP Stapling.

Free vs commercial SSL

Let's Encrypt revolutionized the SSL market by offering free DV certificates. For most sites, free SSL is perfectly sufficient.

When free SSL is enough

• Blogs, portfolio sites, company presentation sites.
• Small online stores that use an external payment gateway (which has its own SSL).
• Sites that do not collect sensitive financial data directly.

When to consider commercial SSL

• Large e-commerce sites with direct card processing.
• Financial institutions and healthcare organizations where trust is critical.
• Organizations that want a warranty (insurance against certificate compromise).

BeoHosting offers free Let's Encrypt SSL on all hosting plans, with automatic renewal every 90 days. For users who want a higher validation level, we also offer commercial SSL certificates.

Conclusion

An SSL certificate is not optional - it is a mandatory element of every professional site in 2026. It affects SEO ranking, user trust, data security, and even site speed (thanks to HTTP/2 and HTTP/3). Implementation is simple, especially with the free Let's Encrypt certificate included in most hosting plans. If your site still does not have SSL, install it today - every day without HTTPS is a day of lost visitors and missed conversions.
