    What is SSL?

    SSL is the familiar name for the technology behind HTTPS, which encrypts information travelling between your website and a visitor's browser. Modern websites use TLS, but hosting providers often still call the certificate an SSL certificate.

    The fix

    • Check that your homepage and important pages open using HTTPS.
    • Ask your hosting provider to install a valid certificate if one is missing.
    • Redirect old HTTP addresses to their HTTPS versions.
    • Enable automatic certificate renewal and check that it works.

    Does every page of your site start with https and show the padlock?

    In more detail

    What HTTPS protects, and what to check

    The reel explains SSL through a familiar sign: the padlock beside a web address. The important part is the secure connection behind that sign. HTTPS encrypts information travelling between a visitor's browser and your website, helping protect it from being read or changed in transit. This matters when someone sends an enquiry, enters contact details or signs into an account.

    SSL is the name many business owners recognise, although modern secure connections use its successor, TLS. Hosting companies still commonly describe the certificate as an SSL certificate. You do not need to manage the technical terminology yourself, but you should know who looks after the certificate and whether renewal happens automatically.

    Start with the check in the video: open your website and inspect the address and connection information. Browser designs differ, so a secure site may show a settings or connection icon rather than a padlock. Look for HTTPS and check for any security warning. Repeat this on your contact page, service pages and any separate booking or payment pages.

    If a certificate is missing, expired or does not cover the address being used, ask your hosting provider or website manager to investigate. Installing a certificate is only part of the job. Visitors following an old HTTP link should be redirected to the secure version, and your navigation should also use the correct addresses.

    A page can use HTTPS while still trying to load an image, script or other resource over HTTP. This is called mixed content, and browsers may block those resources or report a problem. After changing a site to HTTPS, check that images display, forms submit and essential features still work. Ask your developer to replace any remaining insecure resource addresses.

    Finally, treat certificate renewal as ongoing maintenance rather than a launch task you can forget. Automatic renewal reduces manual work, but it still needs to function correctly. HTTPS protects the connection; it does not prove that a business is trustworthy or remove the need for secure passwords, software updates and careful handling of customer information.

    Common questions

    Why does my browser not show a padlock?

    Some browsers now use a connection or settings icon instead of a padlock. Check the connection information and confirm that the address uses HTTPS without a security warning.

    Does HTTPS mean my whole website is secure?

    HTTPS protects information travelling between the browser and your website. You still need software updates, secure account access and appropriate protection for stored customer information.

    What should I do if my certificate expires?

    Contact your hosting provider or website manager to renew or replace it. Ask them to check automatic renewal as well, so the underlying problem is addressed.
