How to convert website http to https in Easy way?

Converting your website from HTTP to HTTPS involves several steps to ensure that the transition is smooth, secure, and optimized for performance. Here’s how to do it in an advanced and comprehensive way:

1. Obtain an SSL/TLS Certificate
Choose a Certificate Authority (CA): Obtain an SSL/TLS certificate from a reputable Certificate Authority (e.g., Let's Encrypt, DigiCert, Comodo). Let's Encrypt is a popular free option.

Select the Right Type of Certificate:
Single Domain: Covers one domain (e.g., www.example.com).
Wildcard: Covers a domain and all its subdomains (e.g., *.example.com).
Multi-Domain (SAN): Covers multiple domains (e.g., example.com, example.net).

2. Install the SSL/TLS Certificate

Place your certificate files in a directory (e.g., /etc/ssl/certs/).
Update your Apache configuration:

<VirtualHost *:443>
    ServerName example.com
    DocumentRoot /var/www/html

    SSLEngine on
    SSLCertificateFile /etc/ssl/certs/example.com.crt
    SSLCertificateKeyFile /etc/ssl/private/example.com.key
    SSLCertificateChainFile /etc/ssl/certs/example.com.chain.crt
</VirtualHost>

sudo service apache2 restart

Place your certificate files in a directory (e.g., /etc/nginx/ssl/).
Update your Nginx configuration:

server {
    listen 443 ssl;
    server_name example.com;

    ssl_certificate /etc/nginx/ssl/example.com.crt;
    ssl_certificate_key /etc/nginx/ssl/example.com.key;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers HIGH:!aNULL:!MD5;

    location / {
        root /var/www/html;
        index index.html;
    }
}

sudo systemctl restart nginx

3. Redirect HTTP to HTTPS
Force HTTPS in Apache:

<VirtualHost *:80>
    ServerName example.com
    Redirect permanent / https://example.com/
</VirtualHost>

Force HTTPS in Nginx:

server {
    listen 80;
    server_name example.com;
    return 301 https://$host$request_uri;
}

4. Update Internal Links and Resources
Absolute URLs: Update all internal links, images, scripts, and stylesheets to use https://.
Relative URLs: Use relative URLs where possible to avoid hard-coding the protocol.

5. Update Your CMS Settings
If you’re using a CMS like WordPress, Joomla, or Drupal, update the base URL in the settings to use https://.
WordPress Example:
Go to Settings > General and update the WordPress Address (URL) and Site Address (URL) to https://example.com.

6. Update External Services
Google Search Console: Add the HTTPS version of your site to Google Search Console.
Google Analytics: Update your property settings to use HTTPS.
CDN Configuration: If you’re using a CDN, ensure that it is configured to serve HTTPS.

7. Mixed Content Fixes
Identify Mixed Content: Use browser developer tools or online tools like Why No Padlock? to identify and fix mixed content issues (HTTP resources on an HTTPS page).
Fix Mixed Content: Replace all HTTP URLs in your site’s HTML, CSS, and JavaScript files with HTTPS URLs.

8. Enable HTTP Strict Transport Security (HSTS)
HSTS instructs browsers to only access your site over HTTPS, even if users try to use HTTP.

Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"

add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;

9. Optimize HTTPS Performance
Enable HTTP/2 or HTTP/3: Ensure your server is configured to use HTTP/2 or HTTP/3, which is faster and more efficient over HTTPS.
Session Resumption: Enable session resumption to improve performance by reusing SSL/TLS session parameters.
OCSP Stapling: Reduce SSL handshake time by enabling OCSP stapling.

SSLUseStapling on
SSLStaplingCache "shmcb:logs/stapling-cache(32768)"

ssl_stapling on;
ssl_stapling_verify on;

10. Test the SSL Configuration
Use tools like Qualys SSL Labs to test your SSL configuration. Aim for an A+ rating, which indicates strong encryption and correct configuration.

11. Update Your Sitemap and Robots.txt
Sitemap: Update your XML sitemap to include the HTTPS versions of all URLs.
Robots.txt: Ensure your robots.txt file references the HTTPS sitemap if applicable.

12. Monitor for Issues Post-Migration
Crawl Errors: Monitor Google Search Console for crawl errors after the migration.
Traffic Drops: Keep an eye on analytics to ensure there’s no significant drop in traffic or issues with indexing.
User Feedback: Collect user feedback to catch any issues with the transition that might have been missed.
You can ensure a smooth and secure transition from HTTP to HTTPS and improving your website’s security, performance, and search engine rankings By following these advanced steps.

How to Reduce Lazy Load Resources

How to Reduce Lazy Load Resources in Website Reduce Lazy Load Resources: Utilize lazy loading for resources such as images, scripts, and stylesheets. This means only loading these resources when they are needed, which can help reduce the initial DOM size and improve page load performance. Diagnose performance issues, Performance Values are estimated and may vary. The performance score is calculated directly from these metrics. See calculator. Images:  Lazy loading images can be achieved by setting the loading attribute to "lazy" on the <img> tag. This tells the browser to load the image only when it's about to come into view. <img alt="Lazy-loaded image" src="placeholder.png" data-src="image.png" class="lazyload" /> <script>   document.addEventListener('DOMContentLoaded', function() {     var lazyImages = document.querySelectorAll('img.lazyload');     //...
