SSL Certificates and HTTPS: What They Are, Why They Matter, and How Webflow Handles Them
Key takeaways
- SSL encrypts the connection between a visitor's browser and your server, switching your site to HTTPS — essential for any organisation asking for donations or collecting personal data.
- HTTPS is not optional: HTTP sites trigger browser "Not Secure" warnings, are deprioritised by Google, fall short of baseline GDPR expectations for forms, and cannot process payments.
- Webflow provisions and renews a free SSL certificate automatically via Let's Encrypt, covering both the root domain and the www subdomain with no manual installation.
- The certificate is issued only after DNS points to Webflow, and there can be a delay of up to 24-48 hours before it is fully active.
- Even with SSL active, "mixed content" — resources loaded over HTTP, often from migrated images or third-party embeds — can still trigger warnings, so check the browser console and update those URLs to HTTPS.
- Additional subdomains beyond root and www need their own SSL coverage, typically handled by whichever service they point to.
Summary
What SSL certificates are, why HTTPS matters for donor trust, GDPR compliance, and SEO — and why Webflow's automatic SSL provisioning is one of the strongest arguments for the platform.
What SSL Is and Why Your Nonprofit Website Needs It
SSL (Secure Sockets Layer) — now technically TLS (Transport Layer Security) — encrypts the connection between a visitor's browser and your website's server. When SSL is active, your site loads over HTTPS instead of HTTP, and the browser shows a padlock icon.
For nonprofit websites, SSL isn't optional:
- Browser warnings: Chrome, Firefox, and Safari all display "Not Secure" warnings on HTTP sites. For an organisation asking for donations or collecting personal data, this warning undermines trust immediately.
- Google ranking signal: HTTPS is a confirmed Google ranking factor. HTTP sites are deprioritised.
- Data protection: If your site has forms (contact, donation, newsletter sign-up), SSL encrypts the data in transit. This is a baseline GDPR expectation.
- Donation platform requirement: Payment processors require HTTPS. A donation page on an HTTP site won't process payments.
How SSL Works on Webflow
Webflow handles SSL automatically for sites hosted on Webflow. When you connect a custom domain, Webflow provisions a free SSL certificate through Let's Encrypt and manages renewal automatically.
This means:
- No need to purchase an SSL certificate separately
- No manual installation or configuration required
- Certificate renewal happens automatically — no annual renewal process to manage
- Both the root domain (socialectric.com) and www subdomain (www.socialectric.com) are covered
The SSL certificate is provisioned after DNS records are correctly pointed to Webflow. There can be a delay of up to 24–48 hours after DNS propagation before the certificate is fully active.
Verifying SSL Is Active
Browser Check
- Visit your site in Chrome
- Look at the address bar — there should be a padlock icon before the URL
- Click the padlock → "Connection is secure" → certificate details
- Confirm the certificate is valid and not expired
Webflow Dashboard Check
In Webflow: Site Settings → Hosting → look for the SSL status indicator next to your custom domain. It should show as active/connected.
Mixed Content Check
Even with SSL active, your site can still show security warnings if it loads resources (images, scripts, fonts) over HTTP instead of HTTPS. This is called "mixed content."
To check: open your site, press F12 to open developer tools, and look at the Console tab. Mixed content warnings will appear as yellow or red messages referencing HTTP resources.
Common causes of mixed content on nonprofit Webflow sites:
- Images uploaded with absolute HTTP URLs (usually from content migration)
- Embedded content from third parties loaded over HTTP
- Custom code referencing HTTP resources
Fix by updating all resource URLs to HTTPS, or use protocol-relative URLs (//example.com/image.jpg).
HTTPS Redirect
Your site should automatically redirect HTTP requests to HTTPS. On Webflow, this is handled at the hosting level — Webflow forces HTTPS by default.
Verify by typing http://yourdomain.com in the browser. It should immediately redirect to https://yourdomain.com. If it doesn't, check your Webflow hosting settings.

What About Subdomains?
If your nonprofit uses subdomains (e.g., events.yourdomain.com or donate.yourdomain.com), each subdomain needs its own SSL coverage. Webflow's automatic SSL covers the root domain and www subdomain. Additional subdomains pointed to external services (donation platforms, event tools) are handled by those services' own SSL.
Common SSL Issues on Nonprofit Sites
"Your connection is not private" error after domain change: Usually means DNS hasn't fully propagated or the SSL certificate hasn't been provisioned yet. Wait 24–48 hours. If it persists, check DNS records in Webflow hosting settings.
Mixed content warnings despite HTTPS: Some element on the page is loading over HTTP. Check images, embeds, and custom code for HTTP references.
SSL certificate expired: Should not happen on Webflow (auto-renewal), but if you're on a different host, set a calendar reminder 30 days before expiry.
