HTTP vs. HTTPS, Which Is Better for SEO?

The difference between HTTP and HTTPS goes beyond just a letter. While both are protocols used for data transfer on the web, HTTPS (Hypertext Transfer Protocol Secure) adds an essential layer of encryption to protect data, making it the clear winner for SEO. From my experience, transitioning a site to HTTPS not only enhances its security but can also positively impact its search engine ranking, helping it gain more trust and visibility.

Understanding HTTP and HTTPS

What is HTTP?

HTTP, or Hypertext Transfer Protocol, is a protocol that facilitates data communication between the user’s browser and the web server. It transfers data in plain text, meaning that any data sent over HTTP, such as form submissions or login credentials, is easily accessible to anyone intercepting the data.

What is HTTPS?

HTTPS is the secure version of HTTP. It uses SSL (Secure Sockets Layer) or its successor, TLS (Transport Layer Security), to encrypt data exchanged between the user’s browser and the web server. This encryption ensures that sensitive information remains private, creating a safer user experience.

Why HTTPS is Essential for SEO

1. Google’s Ranking Boost for HTTPS Sites

In 2014, Google confirmed that HTTPS is a ranking factor, giving secure websites a slight ranking advantage. This SEO boost is part of Google’s broader initiative to make the web safer for users. If two sites are identical in every other SEO aspect, the HTTPS-enabled site is more likely to rank higher.

2. Enhanced User Trust

Security plays a crucial role in user experience. HTTPS provides users with a visual indication (a padlock symbol) that a website is secure, which builds trust. This trust factor can reduce bounce rates and increase engagement, positively affecting rankings. Learn more about the importance of user experience in on-page SEO.

3. Prevention of Data Interception and Manipulation

HTTPS ensures that all data transferred between the browser and the server is encrypted. This protects user information from being intercepted by third parties and prevents malicious entities from modifying content during transmission. Google prioritizes secure experiences for users, making HTTPS a critical component for any website seeking SEO success.

Transitioning from HTTP to HTTPS: Step-by-Step Guide

Step 1: Obtain an SSL Certificate

To enable HTTPS, you need an SSL certificate, which authenticates your website’s identity and enables encrypted connections. Most hosting providers offer SSL certificates, and some even provide free options through services like Let’s Encrypt.

Step 2: Install the SSL Certificate

After acquiring the SSL certificate, install it on your web server. Many hosting providers offer step-by-step guides or automated installations to make this process straightforward.

Update all internal links to point to HTTPS versions of your site’s URLs. This can be done by using a search-and-replace tool to modify links in your site’s content, CSS, and JavaScript files.

Step 4: Set Up 301 Redirects from HTTP to HTTPS

Redirecting HTTP URLs to their HTTPS counterparts using 301 redirects ensures that search engines and users are directed to the secure version of your site. This preserves the SEO value from your HTTP pages and consolidates traffic to HTTPS.

Step 5: Update Canonical Tags and Sitemaps

Make sure that all canonical tags and XML sitemaps reflect HTTPS URLs. This guides search engines to index only the HTTPS versions of your pages, avoiding duplicate content issues. Read more about how canonical tags can help manage duplicate content.

Step 6: Inform Google and Bing of the Change

Update your site in Google Search Console and Bing Webmaster Tools. Resubmit your sitemap with HTTPS URLs, which helps search engines understand and index your new secure URLs faster.

Common SEO Mistakes During HTTP to HTTPS Migration

1. Not Implementing 301 Redirects Correctly

Failing to set up 301 redirects from HTTP to HTTPS can result in duplicate content, where both HTTP and HTTPS versions are indexed by search engines. This can dilute your SEO efforts, so it’s essential to ensure all redirects are in place.

If your site has backlinks from external sites pointing to HTTP URLs, those links should ideally be updated to HTTPS. While you may not have direct control over these links, reaching out to the site owners for an update can help maximize SEO benefits.

3. Inconsistent Use of HTTPS Across Pages

Sometimes, websites mistakenly serve some pages via HTTPS and others via HTTP. This inconsistency confuses search engines and can impact your rankings. Ensure that every page is securely served over HTTPS.

SEO and Security Benefits of HTTPS

1. Protecting User Data and Privacy

HTTPS encrypts all data, making it nearly impossible for hackers to intercept. This is particularly important for eCommerce sites or any site collecting user data, as it protects information like credit card numbers and passwords.

2. Maintaining Referral Data in Google Analytics

When traffic moves from an HTTPS site to an HTTP site, referral data is lost and attributed as “Direct” traffic in Google Analytics. Moving your site to HTTPS preserves referral data, giving you a clearer picture of traffic sources.

3. Meeting Browser Security Standards

Modern browsers like Chrome display a “Not Secure” warning for HTTP sites. This can discourage users from browsing non-HTTPS sites, particularly if they need to input sensitive information. By securing your site with HTTPS, you improve user trust and potentially increase engagement metrics.

Monitoring the Impact of HTTPS on SEO

After migrating to HTTPS, use Google Search Console to monitor your site's indexing status, ensuring that only the HTTPS versions of your pages are indexed. Additionally, track metrics like engagement time, bounce rate, and session duration in Google Analytics to gauge how users are interacting with your secure site.

Conclusion

Switching from HTTP to HTTPS is essential for any website serious about its SEO performance. HTTPS not only improves search rankings but also enhances user trust, security, and compliance with modern web standards. From my view, migrating to HTTPS was one of the most impactful steps I took to improve site credibility and SEO performance, and it remains a vital component of technical SEO best practices.
