What is SSL and HTTPS?
SSL (Secure Sockets Layer) and HTTPS (HyperText Transfer Protocol Secure) are technologies that guarantee the security of data transmission between a server and a browser. SSL encrypts information so that it cannot be intercepted by third parties, which is especially crucial when handling sensitive data such as passwords or credit card information.
HTTPS is the secure version of HTTP, and its implementation is essential for any website looking to protect its users' information. As of 2014, browsers began marking sites without HTTPS as "not secure," which can negatively affect user trust and site SEO.
Benefits of implementing SSL in WordPress
Implementing SSL on your WordPress site not only improves security, but also brings with it several benefits:
- SEO improvement: Google prioritizes HTTPS sites in its search results.
- User confidence: A padlock in the address bar indicates to users that their information is protected.
- Data protection: Encryption of sensitive information, which is crucial for online stores and sites that handle personal data.
How to obtain an SSL certificate
There are several ways to get an SSL certificate for your WordPress site:
1. Free certificates
One of the most popular options is Let's Encryptwhich offers free and automatic SSL certificates. Many hosting providers include this option in their control panels, making installation easy.
2. Payment Certificates
If you need a higher level of validation (such as an EV certificate), you can opt for paid certificates through companies such as Comodo, Symantec o GoDaddy. These certificates usually include additional warranties and technical support.
Installing the SSL certificate on WordPress
Once you have obtained your SSL certificate, the next step is to install it on your server. Here's how to do it:
1. Accessing your hosting control panel
Log in to your hosting provider's control panel. Most panels offer an option to manage SSL certificates.
2. Install the certificate
Locate the SSL/TLS and follow the instructions to add your certificate.
- Select the domain to which you want to add SSL.
- Upload the certificate and private key if necessary.
- Save the changes and activate the certificate.
Configure WordPress to use HTTPS
Once the certificate is installed, it is crucial that you configure your WordPress site to use HTTPS by default.
1. Update the site URL
Go to Settings > General in your WordPress administration panel and change the URL of the site from http://tusitio.com a https://tusitio.com.
2. Redirect HTTP to HTTPS traffic
To ensure that all visitors are automatically redirected to the secure version of your site, you can add the following lines to the file .htaccess:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
Check that everything is working properly
After making all these changes, it is essential that you check that your site is running smoothly.
- Make sure that there is no mixed content (HTTP resource loading on an HTTPS page).
- It uses tools such as SSL Labs to verify your SSL configuration.
- Check that all internal links are updated to HTTPS.
Common problems and solutions
Sometimes, implementing SSL can present some challenges. Here are some common problems and how to solve them:
1. Mixed content
If some elements of your page load over HTTP, the browser may display a security warning. To fix this, be sure to upgrade all internal links and external resources to HTTPS.
2. Redirection errors
If after implementing the SSL certificate your site shows a 404 error or redirects incorrectly, please check the settings in your .htaccess or use a plugin to manage redirects.
Conclusion
Implementing SSL and HTTPS on your WordPress site is an essential step to ensure the security of your visitors and improve your SEO. With the right steps, you can turn your site into a secure and trusted environment.
