How to Make a Website Secure in Google Chrome: A Step-by-Step Guide

When visitors open your website, they decide quickly whether they trust it. If Google Chrome shows a “Not secure,” “Dangerous,” or “Your connection is not private” warning, many users will leave right away.

That warning can hurt:

• Leads
• Sales
• Form submissions
• Search trust
• Brand credibility
• Customer confidence

If you are asking how to make a website secure in Google Chrome, start with the basics: HTTPS, SSL/TLS certificates, clean redirects, safe content loading, malware cleanup, and regular website maintenance.

This guide explains the process in simple steps.

What Does “Secure” Mean in Google Chrome?

A secure website in Chrome usually means the site loads through HTTPS with a valid SSL/TLS certificate.

HTTPS protects information as it travels between the visitor’s browser and your server.

This matters when users submit:

• Passwords
• Contact forms
• Payment details
• Account information
• Uploaded files
• Private messages
• Email addresses

A secure connection does not automatically mean a website is trustworthy. It only means the browser connection is protected.

A truly secure website also needs clean code, updated software, safe hosting, malware protection, strong passwords, and responsible data handling.

Why Chrome Shows “Not Secure”

Chrome may show website security warnings for several reasons.

Common causes include:

• No SSL certificate
• Expired SSL certificate
• Invalid SSL certificate
• Wrong certificate domain
• HTTP pages instead of HTTPS
• Mixed content
• Broken redirects
• Malware or phishing detection
• Unsafe downloads
• Hacked pages
• Insecure forms
• Old server settings
• Suspicious scripts

Some issues are simple fixes. Others may mean the website has been compromised.

Quick Answer: How to Make a Website Secure in Google Chrome

Use this checklist:

1. Install a valid SSL/TLS certificate.2. Force all pages to load over HTTPS.3. Redirect HTTP URLs to HTTPS.4. Fix mixed content errors.5. Renew expired certificates.6. Update WordPress, plugins, themes, and server software.7. Scan for malware.8. Check Google Search Console security reports.9. Secure forms, login pages, and checkout pages.10. Remove unsafe scripts, ads, or downloads.11. Add security headers.12. Monitor the site regularly.

The goal is simple: every page should load cleanly over HTTPS without Chrome warnings.

Step 1: Check Your Website in Chrome

Start by opening your website in Google Chrome.

Look at the icon next to the web address.

Chrome may show:

• A secure/default icon
• “Not secure”
• “Dangerous”
• “Your connection is not private”
• “Deceptive site ahead”

Do not check only the homepage.

Test important pages, including:

• Homepage
• Contact page
• Login page
• Checkout page
• Blog posts
• Landing pages
• Old URLs
• Subdomains
• Mobile version

A site may be secure on one page and insecure on another.

Step 2: Install a Valid SSL/TLS Certificate

An SSL/TLS certificate allows your website to use HTTPS.

Without it, Chrome may warn users that the connection is not secure.

Common Certificate Problems

Chrome may show warnings if:

• No certificate exists
• The certificate expired
• The certificate belongs to another domain
• The certificate chain is incomplete
• The server is misconfigured
• The certificate does not cover the www version

What to Check

Ask your host or developer to confirm:

• The certificate is installed
• It covers your exact domain
• It covers www and non-www versions
• It covers needed subdomains
• Auto-renewal is active
• The certificate chain is complete

Examples:

https://example.comhttps://www.example.comhttps://blog.example.comhttps://shop.example.com

If your site uses multiple subdomains, make sure each one is covered.

Step 3: Force Your Website to Use HTTPS

Installing a certificate is not enough. Your website must actually load over HTTPS.

Every HTTP page should redirect to HTTPS.

Example:

http://example.com/contactshould redirect to:https://example.com/contact

Use a permanent 301 redirect when possible.

Avoid Redirect Chains

A messy redirect chain can slow your site and cause errors.

Poor example:

http://example.com→ http://www.example.com→ https://www.example.com→ https://example.com

Better example:

http://example.com→ https://example.com

A clean redirect improves both security and user experience.

Step 4: Fix Mixed Content Errors

Mixed content happens when an HTTPS page loads some files through HTTP.

For example:

<img src="http://example.com/image.jpg"><script src="http://example.com/script.js"></script><link rel="stylesheet" href="http://example.com/style.css">

The page itself may be HTTPS, but insecure files can still trigger warnings.

Common Mixed Content Sources

Mixed content often comes from:

• Images
• Fonts
• CSS files
• JavaScript files
• Videos
• iframe embeds
• Analytics scripts
• Ad scripts
• Old theme files
• Plugin assets
• CDN resources

How to Fix Mixed Content

Update all HTTP resources to HTTPS.

Example:

<!-- Insecure --><img src="http://example.com/logo.png"><!-- Secure --><img src="https://example.com/logo.png">

For WordPress sites, mixed content often appears after moving from HTTP to HTTPS.

Check posts, pages, widgets, themes, page builders, media files, and database links.

Step 5: Update WordPress URL Settings

If your website uses WordPress, check the site URL settings.

Go to:

WordPress Dashboard → Settings → General

Make sure both fields use HTTPS:

WordPress Address (URL): https://example.comSite Address (URL): https://example.com

If these still show HTTP, WordPress may generate insecure links.

Also review:

• Menus
• Widgets
• Internal links
• Media files
• Page builder templates
• Custom fields
• Theme settings

Back up your website before making database-wide changes.

Step 6: Secure Forms, Login Pages, and Checkout Pages

Forms are high-risk because users submit information through them.

Secure these pages first:

• Login page
• Registration page
• Contact form
• Quote request page
• Appointment page
• Checkout page
• Newsletter signup
• Customer portal
• File upload page

Form Security Checklist

1. Page loads over HTTPS.2. Form action URL uses HTTPS.3. No mixed content appears.4. CAPTCHA or spam protection is enabled.5. Form plugin is updated.6. Sensitive data is not emailed insecurely.7. Admin access uses MFA where possible.8. Form submissions are stored securely.

If your site collects payments, use a reputable payment processor and follow security requirements.

Step 7: Renew Expired SSL Certificates

An expired certificate can trigger Chrome warnings immediately.

Prevent this by setting up:

• Auto-renewal
• Hosting alerts
• Calendar reminders
• Domain monitoring
• Backup certificates for complex setups

If your certificate expires, renew it and retest the website in Chrome.

Do not wait for visitors to report the issue.

Step 8: Check for Malware or Hacked Content

HTTPS does not guarantee your website is safe.

A website can have a valid certificate and still contain malware, phishing pages, spam injections, or harmful redirects.

Signs Your Website May Be Compromised

Watch for:

• Unknown admin users
• Strange redirects
• Unfamiliar files
• New pages you did not create
• Sudden traffic drops
• Security warnings in Chrome
• Search results showing spam text
• Hosting provider alerts
• Visitors reporting pop-ups

If you see these signs, act quickly.

Step 9: Use Google Search Console

Google Search Console helps website owners monitor security and search issues.

Check:

• Security Issues report
• Manual Actions report
• Indexing status
• Crawled pages
• Page experience reports
• Sitemap status

If Google detects malware, phishing, hacked content, or harmful behavior, it may appear in the Security Issues report.

After Cleaning a Hacked Website

Once the issue is fixed:

1. Verify ownership in Search Console.
2. Review Security Issues.
3. Clean affected pages.
4. Remove malicious code.
5. Patch vulnerabilities.
6. Request a review if available.

Only request review after the cleanup is complete.

Step 10: Update CMS, Plugins, Themes, and Server Software

Outdated software is one of the most common security risks.

Update:

• WordPress core
• Themes
• Plugins
• PHP version
• Server packages
• Ecommerce software
• CMS extensions
• Website builders
• Security tools

Also delete anything you do not use.

Remove:

• Inactive plugins
• Old themes
• Unused admin accounts
• Old staging files
• Test directories
• Public backup files

Unused software can still create risk.

Step 11: Use Strong Admin Security

Your site is only as secure as its admin access.

Admin Security Checklist

Use:

• Strong passwords
• Unique admin accounts
• Multi-factor authentication
• Limited admin roles
• Login attempt limits
• Activity logging
• Regular user reviews
• Secure hosting login
• No shared admin accounts

If a former employee, contractor, or vendor still has access, remove it.

Admin security protects both your website and your reputation.

Step 12: Add Security Headers

Security headers tell browsers how to handle your website.

Useful headers include:

• HTTP Strict Transport Security
• Content Security Policy
• X-Content-Type-Options
• Referrer-Policy
• Permissions-Policy
• X-Frame-Options

Example:

Strict-Transport-Security: max-age=31536000; includeSubDomainsX-Content-Type-Options: nosniffReferrer-Policy: strict-origin-when-cross-origin

Be careful with strict settings like HSTS. If configured incorrectly, they can cause access problems.

Ask a developer or hosting provider for help if needed.

Step 13: Review Third-Party Scripts

Third-party scripts can create security problems.

These may include:

• Ad scripts
• Analytics tags
• Chat widgets
• Tracking pixels
• Affiliate scripts
• Embedded forms
• Video embeds
• Social widgets

Ask:

Do we still use this script?Is it loaded over HTTPS?Is the provider trusted?Does it slow the site?Could it inject risky content?Does it request unnecessary access?

Remove scripts you no longer need.

Step 14: Secure Your Domain and Hosting

Chrome warnings are not always caused by page content. Sometimes the issue starts with domain or hosting access.

Domain Security Tips

Use:

• Strong registrar password
• MFA at your domain registrar
• Domain lock
• DNS change alerts
• Accurate contact information
• Limited DNS access

Hosting Security Tips

Use:

• Reputable hosting
• MFA for hosting accounts
• Regular backups
• Malware scanning
• Secure FTP or SSH
• File permission controls
• Limited user access

If someone gains access to your domain or hosting, they can redirect your site or upload harmful files.

Step 15: Fix “Your Connection Is Not Private” Errors

Chrome may show this error when it cannot verify the SSL certificate.

Common causes include:

• Expired certificate
• Wrong domain certificate
• Missing certificate chain
• Server misconfiguration
• Old TLS settings
• Incorrect system time on visitor device
• Self-signed certificate

Website Owner Checklist

Check:

1. Certificate expiration date.2. Certificate domain coverage.3. Intermediate certificate chain.4. HTTPS redirects.5. Server configuration.6. HSTS settings.7. www and non-www versions.8. Subdomain coverage.

After fixing the issue, test again in Chrome.

Step 16: Fix “Deceptive Site Ahead” Warnings

A “Deceptive site ahead” warning is serious.

It may mean Google suspects phishing, malware, social engineering, or unsafe behavior.

What to Do

1. Check Google Search Console.
2. Review Security Issues.
3. Scan your website files.
4. Remove phishing pages.
5. Remove unauthorized redirects.
6. Change admin passwords.
7. Update plugins, themes, and software.
8. Remove suspicious users.
9. Patch vulnerabilities.
10. Request review after cleanup.

Do not ignore this warning. It can damage traffic and trust quickly.

Step 17: Build Trust Beyond HTTPS

A secure connection is only one part of trust.

Visitors also look for signs that your business is real and responsible.

Add:

• Clear business name
• Contact information
• Privacy policy
• Terms of service
• Refund policy
• About page
• Secure checkout
• Real customer support options
• Accurate business listings

Security protects the connection. Trust protects the relationship.
