HTTPS and Mixed-Content Checks

Make sure every page, image, script and form on your website loads securely over HTTPS, without browser warnings, broken padlocks or blocked resources.

The Padlock Visitors Expect

HTTPS encrypts the connection between a visitor’s browser and your website, protecting form submissions, login details and payment information from being read or altered in transit. Today it is a basic expectation rather than an optional extra. Modern browsers label plain HTTP pages as not secure, particularly when they contain forms, and many visitors will leave rather than enter their phone number or email address on such a page. Google has confirmed HTTPS as a lightweight ranking signal, and many modern browser features only work on secure pages.

Simply installing an SSL certificate is not the end of the job, however. A website can have a valid certificate and still show warnings if some resources, such as images, fonts, scripts, stylesheets, iframes or form actions, are loaded over HTTP. This is called mixed content. Browsers may block insecure scripts and styles entirely, which can break layouts, sliders, forms, maps or tracking, or they may show a warning instead of a clean padlock. Other common issues include certificates that expire unnoticed, certificates that do not cover all domain variations, HTTP pages that are still accessible without redirects, and outdated server security settings.

ViV Softech Solution is a website designing and digital marketing agency based in Delhi. We check and fix HTTPS configurations for websites across India, from small business sites to ecommerce stores. This page explains what a correct HTTPS setup includes, what mixed content is and how to find it, the common causes on WordPress and other platforms, how HTTPS relates to redirects and canonicals, certificate management, security headers, how we work and what affects cost. It forms part of our technical SEO services and complements our website security work.

What a Correct HTTPS Setup Includes

Valid Certificate

A trusted, unexpired SSL/TLS certificate that covers every host name you use, including www and any subdomains.

Single-Step Redirects

Every HTTP URL redirects permanently to its HTTPS equivalent in one hop.

No Mixed Content

All images, scripts, styles, fonts, embeds and form actions load over HTTPS.

Consistent Signals

Canonicals, internal links, sitemaps and structured data all use HTTPS URLs.

Modern Server Settings

Current TLS versions, secure ciphers and, when ready, an HSTS header.

Automatic Renewal

Certificates renew automatically, with alerts in case renewal fails.

Understanding Mixed Content

Active mixed content

Scripts, stylesheets, iframes and similar resources that can change how a page behaves. Because an attacker could tamper with them in transit, modern browsers block them on HTTPS pages. The result can be a page that looks broken, a slider that does not move, a form that fails to submit, a map that does not appear or analytics that stop recording.

Passive mixed content

Images, audio and video loaded over HTTP. Browsers increasingly try to upgrade these to HTTPS automatically, and block them if the secure version does not exist. Older browsers show a warning or remove the padlock. Either way, visitors may see missing images or a reduced sense of security.

Mixed content also includes forms whose action points to an HTTP address, which browsers warn about before submission, and links to HTTP versions of your own pages, which force an extra redirect. All of these should be corrected so that every request your pages make is secure.

Where Mixed Content Comes From

Hard-coded HTTP links in page content created before the site moved to HTTPS, especially images inserted into older posts and pages.
Theme and page builder settings storing absolute HTTP URLs for logos, backgrounds and custom CSS.
Plugin settings and widgets that saved HTTP addresses.
Custom code in headers, footers or template files that loads scripts or fonts over HTTP.
Third-party embeds such as old video players, maps, chat widgets, booking tools or advertising scripts.
Serialised data in the database that a simple find-and-replace can corrupt if not handled with proper tools.
CDN or proxy settings serving assets over HTTP or rewriting URLs incorrectly.
Email templates and downloadable files linking to insecure addresses.

How We Find and Fix It

Finding issues

We crawl the entire website with an SEO crawler configured to report insecure resources, check browser developer tools on key templates for mixed content warnings and blocked requests, search the database for HTTP references to your own domain, and review theme, plugin and custom code settings. We also test forms, checkout and other interactive features to ensure nothing is silently failing.

Fixing issues

After a full backup, we update URLs in the database using tools that handle serialised data safely, correct theme and plugin settings, update custom code to use HTTPS, and replace or update third-party embeds that do not support HTTPS. Where a resource is no longer available securely, we host it locally or find an alternative. Browser features such as upgrade-insecure-requests can help as a safety net, but we fix the underlying URLs rather than relying only on them.

HTTPS, Redirects and Search Engines

Moving a website from HTTP to HTTPS is technically a site migration, because every URL changes. Search engines handle it well when the signals are consistent: every HTTP URL should return a single permanent redirect to its HTTPS equivalent, canonical tags should reference HTTPS, internal links and XML sitemaps should list only HTTPS URLs, and structured data and hreflang annotations should be updated too. Redirect chains, such as HTTP to HTTPS and then non-www to www in separate steps, should be combined into one hop. We also recommend a Google Search Console domain property, which covers both protocols and all subdomains together, so that reporting is not split. After the change, we monitor indexing to confirm search engines have switched to the HTTPS versions. See canonicalization and redirect and 404 error management.

Certificates and Their Management

Types of certificates

Domain-validated certificates, including free certificates offered by many hosts, provide the same encryption as paid ones and suit most business websites. Organisation-validated and extended-validation certificates involve additional identity checks, which some organisations prefer for their own policy reasons, although browsers no longer display them very differently.

Coverage

The certificate must cover every host name visitors and search engines might use: the root domain, the www version and any subdomains such as shop or blog. Wildcard or multi-domain certificates can simplify this for businesses with several subdomains.

Renewal

Certificate lifetimes have become shorter over time, which makes automatic renewal essential. An expired certificate triggers full-page browser warnings that stop most visitors. We confirm renewal is automated and set up monitoring that alerts you before expiry.

Security Headers and Server Configuration

Beyond the certificate itself, server settings affect how secure your HTTPS connection is. We check that outdated protocol versions are disabled and current TLS versions are enabled, and we review security headers that add protection on top of HTTPS:

Strict-Transport-Security (HSTS): tells browsers to use only HTTPS for your domain. It should be introduced carefully, starting with a short duration, because it is difficult to reverse if any part of the site still needs HTTP.
Content-Security-Policy: controls which sources can load scripts and other resources, and can report mixed content. It needs careful testing to avoid breaking legitimate features.
X-Content-Type-Options, Referrer-Policy and frame options: simple headers that reduce certain risks.

Header changes are tested on staging where possible and introduced gradually. Deeper security hardening is covered by our security hardening service.

Special Situations

Ecommerce and payment pages

Online stores handle personal and payment-related data, so every page, not just checkout, should be served securely. Payment gateways have their own security requirements, and we check that gateway integrations, callbacks and order emails work correctly after HTTPS changes.

Websites behind a CDN or firewall

When a CDN or web application firewall sits in front of your server, both the visitor-to-CDN and CDN-to-server connections should be encrypted. Misconfigured settings can cause redirect loops or insecure origin connections.

Old subdomains and microsites

Forgotten subdomains with expired certificates can show warnings to visitors who find them through old links. We identify them and either secure, redirect or retire them.

Shared hosting limitations

Some older hosting plans make HTTPS difficult or expensive. If your hosting cannot support a proper setup, we explain the options, including moving to more suitable hosting.

Our Process

1. Check: certificate validity, coverage, expiry and server protocol settings. 2. Test variations: HTTP, HTTPS, www and non-www on key URLs. 3. Crawl: find mixed content, insecure forms and HTTP internal links. 4. Back up: files and database before changes. 5. Fix: database URLs, settings, code and embeds. 6. Align: redirects, canonicals, sitemaps and Search Console. 7. Harden: add appropriate security headers gradually. 8. Monitor: certificate expiry, browser warnings and indexing.

What Affects Cost

Website size and amount of older content.
Platform, theme and plugin complexity.
Hosting and server access, including CDN configuration.
Third-party integrations needing updates or replacement.
Whether a full HTTP to HTTPS migration is required.
Ongoing certificate and security monitoring.

Frequently Asked Questions

Usually because some resources load over HTTP (mixed content), HTTP pages are not redirected, or the certificate does not cover the version visitors are using.

For most business websites, yes. Free domain-validated certificates provide the same encryption strength as paid ones.

Handled correctly with proper redirects, the move usually goes smoothly. Short-term fluctuations can occur while search engines update their index.

Resources such as images or scripts loaded over insecure HTTP on a page served over HTTPS.

Yes, once every part of the site works on HTTPS, introduced gradually with a short duration first.

Browsers show full-page warnings and most visitors will leave. Automatic renewal and expiry monitoring prevent this.
