If your browser displays "Not Secure" when visiting your website, it usually means the website is not providing a valid HTTPS connection or there is another security-related configuration problem.
For a professional business website, this should be investigated promptly.
What Does "Not Secure" Mean?
Browsers use security indicators to inform visitors about the connection between their browser and the website.
If your website is accessed using HTTP instead of HTTPS, the connection may not be protected by TLS encryption.
For example:
http://yourdomain.com
instead of:
https://yourdomain.com
A browser may therefore display a security warning or "Not Secure" message.
Common Reasons for the Warning
1. SSL Certificate Is Missing
Your domain may not have a valid SSL/TLS certificate installed.
2. Certificate Has Expired
SSL certificates have validity periods.
An expired certificate can cause browsers to display security warnings.
3. Certificate Does Not Match the Domain
The certificate must cover the domain being accessed.
For example, a certificate issued for:
example.com
may not automatically cover every other domain or subdomain unless those names are included appropriately.
4. Mixed Content
Mixed content occurs when an HTTPS page loads some resources over insecure HTTP.
For example:
https://yourdomain.com
may load an image or script from:
http://example.com/file.js
Browsers can flag or block insecure resources.
5. Incorrect Website Configuration
Your website may not be configured correctly to use HTTPS.
For example, the application may continue generating HTTP URLs.
6. DNS Problems
If your domain points to the wrong server, the expected SSL certificate may not be available.
How to Troubleshoot "Not Secure"
Step 1: Check the Website URL
Make sure you are accessing:
https://yourdomain.com
rather than:
http://yourdomain.com
Step 2: Check the Certificate
Inspect the browser's security information and confirm:
-
The certificate is valid.
-
The certificate covers the correct domain.
-
The certificate has not expired.
Step 3: Check Your DNS
Make sure your domain points to the correct hosting server.
Incorrect DNS configuration can cause the browser to connect to the wrong server.
Step 4: Check for Mixed Content
If the certificate is valid but the page still displays security warnings, check whether the website is loading HTTP resources.
WordPress users can also check whether their WordPress URL and site URL are configured to use HTTPS.
Step 5: Clear Cached Information
Your browser may retain older information.
Test the website using:
-
Private/incognito browsing
-
Another browser
-
Another device
-
Another internet connection
Should HTTP Redirect to HTTPS?
For most modern websites, HTTP traffic should generally be redirected to the HTTPS version.
This ensures visitors are directed to the secure version of the website.
The exact redirect method depends on your hosting environment and website technology.
Does "Not Secure" Affect SEO?
HTTPS is an important part of modern technical website security and is also a ranking signal.
However, resolving an SSL warning alone does not guarantee improved Google rankings.
Your website should also have:
-
Useful content
-
Good technical SEO
-
Fast performance
-
Mobile-friendly design
-
Good user experience
-
Appropriate internal linking
-
Relevant authority and links
