HTTP vs. HTTPS: The SEO Implications of Secure Website Migration

In the evolving digital landscape, the security of a website is not just about protecting user data—it’s also about enhancing search engine visibility and credibility. For businesses like Atomic Social, transitioning from HTTP to HTTPS is not merely a security upgrade but a crucial SEO strategy. This blog discusses the difference between HTTP and HTTPS, the benefits of migrating to a secure server, and the SEO implications that come with this transition.

Understanding HTTP vs. HTTPS

HTTP (HyperText Transfer Protocol) and HTTPS (HyperText Transfer Protocol Secure) are protocols used for transferring data over the web. The key difference between the two is that HTTPS uses an SSL (Secure Sockets Layer) certificate, which encrypts the data transferred between the user and the server. This encryption enhances the security of data exchange, making it extremely difficult for hackers to intercept or tamper with the information.

SEO Benefits of Migrating to HTTPS

  1. Increased Security and Trust:
    • HTTPS encrypts the data exchanged between a visitor’s browser and your server, enhancing the security of sensitive information such as login details and personal information. This added security layer can significantly boost the trust users have in your site, which is increasingly becoming a factor users consider before engaging with a website.
  2. Improved Search Engine Ranking:
    • Google has confirmed that HTTPS is a ranking signal. Websites that are secure may receive a ranking boost over non-secure sites. While this boost may not be significant, in a highly competitive market, even a small advantage can make a difference.
  3. Enhanced User Experience:
    • HTTPS prevents “man-in-the-middle” attacks, ensuring that the content users receive has not been altered. Users are more likely to remain on a secure site longer, reducing bounce rates and improving other metrics like time on site, which can positively impact SEO.
  4. Referrer Data Preservation:
    • HTTPS to HTTPS referral is passed on intact, which means that if someone clicks on a link to your site from another secure site, you’ll be able to see where they came from. With HTTP, this data is lost.

Challenges and Considerations in Migrating to HTTPS

  1. Obtaining SSL Certificates:
    • To switch to HTTPS, you need to obtain and install an SSL certificate. The type of certificate (DV, OV, or EV) will depend on your business needs and budget.
  2. Proper Implementation:
    • Incorrect implementation of HTTPS can lead to issues like mixed content warnings, where some resources load over HTTP while others load over HTTPS. Such warnings can deter users and negatively impact the credibility of your site.
  3. SEO Impacts of Migration:
    • When migrating from HTTP to HTTPS, temporary fluctuations in search rankings can occur. Properly implementing redirects and updating the Google Search Console settings can mitigate these effects.

Best Practices for Migrating to HTTPS

  1. Plan the Migration Carefully:
    • Before transitioning, ensure that every element of your website, including third-party plugins and external scripts, supports HTTPS. Prepare a detailed checklist of tasks to address during the migration.
  2. Use 301 Redirects:
    • Set up 301 redirects from HTTP URLs to HTTPS URLs to inform search engines that the pages have permanently moved. This step helps preserve search engine rankings.
  3. Update Internal Links:
    • Adjust all internal links to point to the HTTPS versions of the URLs to avoid unnecessary redirects and ensure a seamless user experience.
  4. Verify with Google Search Console:
    • After migrating, verify your new HTTPS site in Google Search Console. Submit your new HTTPS sitemap and check for any crawl errors.


For Atomic Social and other businesses striving to maintain an edge in SEO, migrating to HTTPS is a strategic move that reinforces security, builds user trust, and potentially improves search rankings. While the migration process requires careful planning and execution, the long-term benefits of a secure, trusted website in the eyes of both users and search engines can significantly outweigh the temporary challenges.
