If you’ve ever seen a browser warn “Not Secure” when visiting a website, that’s a sign the site is missing HTTPS/SSL — a basic security requirement that every website today must have. This article explains what HTTPS/SSL is and why it matters.
What Is HTTPS/SSL?
SSL (Secure Sockets Layer) is a security certificate that encrypts the data exchanged between a user’s browser and a website’s server. Once HTTPS/SSL is installed, the address bar shows “https://” instead of the regular “http://”, along with a padlock icon.
Why Does Every Website Need HTTPS/SSL?
1. Protects User Data
HTTPS encrypts all data exchanged between users and the website, preventing attackers from stealing sensitive information such as passwords or payment details in transit.
2. An Official Google Ranking Signal
Google officially announced HTTPS as a ranking signal back in 2014. A website without HTTPS may rank lower than competitors that have already adopted it.
3. Builds Trust With Users
Modern browsers such as Chrome and Firefox display a clear “Not Secure” warning on websites without HTTPS, which makes users wary and prone to leaving the site immediately.
4. Mandatory for Websites With Online Payments
For e-commerce sites or any site with payment integration, HTTPS is a mandatory requirement from payment gateways to ensure transaction safety for customers.
Common Types of SSL Certificates
Free SSL (Let’s Encrypt)
Bundled free by many hosting providers, suitable for most small and mid-sized business websites, and offering fully adequate baseline security.
Paid SSL (OV/EV SSL)
Offers a higher level of verification and displays additional business information when the certificate is checked, typically used for financial and banking websites that require the highest level of trust.
How to Check Whether Your Website Has HTTPS
Simply look at the browser’s address bar: if there’s a padlock icon and the address starts with “https://”, the site is secured. If you see a “Not Secure” warning, contact your technical team to install SSL right away.
Does Installing HTTPS Affect a Live Website?
When switching from HTTP to HTTPS, you need to implement proper 301 redirects and update all internal links and your sitemap to avoid disrupting your existing SEO rankings during the transition.
Understanding what HTTPS/SSL is is the first step toward applying this knowledge in practice rather than only grasping it in theory. A deep understanding of HTTPS/SSL is the foundation for implementing a security strategy that stays effective and sustainable over time. This is also why HTTPS/SSL is consistently referenced in authoritative SEO resources today.
Conclusion
HTTPS/SSL is no longer optional — it’s now a mandatory standard for every website, directly affecting security, user experience, and SEO rankings alike. If your website still doesn’t have HTTPS installed or you’re running into issues during migration, contact our technical team for immediate support.
