SSL Installation 101 guide to installing, debunking and affects on SEO. SSL (Secure Sockets Layer) certificates are used to encrypt the communication between a web browser and a web server. They provide a secure connection that protects sensitive data like credit card numbers, login credentials, and personal information from being accessed or intercepted by third parties.
The SSL protocol was originally developed by Netscape in the mid-1990s to enable secure e-commerce transactions and communication over the internet. The first version, SSL 1.0, was never released to the public due to security flaws. SSL 2.0 and 3.0 improved security, and were widely adopted. In the late 1990s, the Internet Engineering Task Force (IETF) took over development of the protocol and renamed it Transport Layer Security (TLS). The term “SSL” is still commonly used to refer to internet security protocols in general.
The primary purpose of SSL certificates is to establish trust between a website and users. It provides assurance that the site is who it claims to be and that the connection is encrypted. This prevents man-in-the-middle attacks where someone tries to eavesdrop on or alter the communication. When a valid SSL certificate is installed on a web server, users will see a padlock icon in the browser address bar and the HTTPS protocol instead of HTTP. This verifies the identity of the website.
Why Use SSL Certificates?
SSL certificates provide several important benefits for websites:
Encrypts Data
SSL certificates encrypt the data transmitted between a website and visitors. This prevents hackers from accessing or intercepting sensitive information like usernames, passwords, credit card details, etc. SSL encryption transforms data into unreadable cipher text during transmission.
Provides Authentication
SSL verifies the identity of a website and establishes that it is operated by a trusted entity. It does this through a validation process with certificate authorities. Visitors can check the SSL certificate to confirm the site’s authenticity.
Builds Trust
The encryption and authentication provided by SSL certificates help build user trust in a website. Visitors feel more secure entering data and conducting transactions on sites protected by SSL. The padlock icon signals it’s safe to share info. This is especially important for ecommerce sites, banks, etc.
Types of SSL Certificates
There are 3 main types of SSL certificates:
Domain Validated SSL Certificates
Domain validated (DV) SSL certificates only verify ownership of the domain name. No identity checks are performed on the business or organization. DV certificates are issued very quickly, usually within minutes or hours, making them the most affordable and popular option. They provide the padlock and https, enabling encryption.
Organization Validated SSL Certificates
Organization validated (OV) SSL certificates require identity verification steps to validate the business registering the certificate. This involves checking official company documents and calling the company to confirm they are requesting the certificate. OV certificates clearly display the organization’s identity in the browser, providing more trust to visitors. Issuance can take 1-3 days.
Extended Validation SSL Certificates
Extended validation (EV) SSL certificates follow strict guidelines for validating identity and undergo thorough vetting by the certificate authority. They provide the maximum level of trust and security, displaying the organization’s name prominently in green font in the browser address bar. The issuance process can take 3-5 days. EV SSLs are recommended for ecommerce sites handling sensitive transactions.
How to Install an SSL Certificate
Installing an SSL certificate involves a few key steps:
Choose a Certificate Authority
The first step is to choose a certificate authority (CA) to purchase your SSL certificate from. Popular options include DigiCert, Comodo, GoDaddy, GlobalSign, Sectigo, and Let’s Encrypt.
When choosing a CA, consider factors like cost, validation levels, browser/platform compatibility, customer support, and reputation. Domain validated (DV) certificates are the most affordable and require only proof of domain ownership. Organization validated (OV) and extended validation (EV) certificates involve more extensive verification and provide more trust, but cost more.
Generate a CSR
Once you’ve chosen a CA, you’ll need to generate a certificate signing request (CSR). This is an encrypted file that contains your public key and information about your server and company.
To generate a CSR, you’ll need your private key. This can be created through your server’s SSL tools or using openssl or keytool commands. Make sure to protect your private key and don’t share it publicly.
When generating the CSR, enter the correct domain name(s) you want covered by the SSL certificate. You may need to generate multiple CSRs for different domains and subdomains.
Install the Certificate
After submitting the CSR, the CA will validate your information and issue the SSL certificate. Most CAs provide instructions for installing the certificate on major platforms like Apache, Nginx, IIS, etc.
The certificate will come with a “chain” of intermediate certificates from the CA. Concatenate your domain certificate with the intermediates to form a full certificate chain. Install the certificate and key in the appropriate locations for your server software.
On many platforms, you’ll need to configure the server to use the certificate. Enable HTTPS and point it to use your new key/certificate for encryption. Restart the server to complete the changes.
Configure HTTPS
The final step is updating your site and server config for HTTPS instead of HTTP. Redirect all HTTP traffic to HTTPS, update canonical tags, sitemaps, HSTS headers, and internal links to use HTTPS URLs.
Test that everything is working properly by visiting your site via HTTPS and confirming there are no certificate warnings or errors. Force a refresh on your browser cache if needed.
Common SSL Installation Errors
Proper SSL certificate installation is crucial for website security and performance. However, there are some common errors that can occur during the installation process:
Mismatched Domain Names
One of the most common SSL installation problems is a mismatch between the domain name on the certificate and the actual website domain. For example, if the certificate is issued for www.example.com but the website is actually hosted on example.com, this will cause browser errors. Always make sure the domain name on the SSL certificate matches exactly with your live website domain.
Expired Certificates
SSL certificates are only valid for a certain time period, usually 1-2 years. If the certificate expires, the website will revert back to HTTP and display security warnings. Check the expiration date before installing a certificate and be sure to renew it before it lapses. Setting calendar reminders can help avoid any interruptions.
Incorrect Server Configuration
The web server software needs to be properly configured to work with the SSL certificate. If the server settings are incorrect, the website may not load correctly over HTTPS. Common configuration issues include missing intermediate certificates and incorrect SSL port binding. Work with your hosting provider to ensure the server is optimized for SSL.
Proactively monitoring for and correcting these types of SSL installation errors is crucial for maintaining a secure website. Testing the site after any changes and watching for warning signs like certificate expiration notices can help avoid problems down the road. Taking the time to properly implement SSL protects website visitors and contributes to a positive user experience.
SSL Certificates and SEO
Implementing SSL certificates on your website can provide SEO benefits in addition to the security aspects. Here are some of the ways SSL impacts SEO:
- HTTPS helps ranking: Google has stated that HTTPS is a ranking signal. Websites using HTTPS may get a slight boost in search rankings, all other factors being equal. Google wants to promote more secure, encrypted web traffic.
- Improves clickthrough rate: Studies show that websites with HTTPS have a higher clickthrough rate in search results. Users feel more comfortable clicking on secure sites. This metric is important for organic traffic and visibility.
- Browser warnings on HTTP: Most modern browsers now display warnings or errors when visiting HTTP sites. This creates friction for users and may cause them to leave your site quickly. HTTPS avoids browser warnings.
- Trust signals: The padlock icon and https in the URL bar signal safety to users. This improves perceptions of trust and credibility for your brand. Google also associates HTTPS with trust.
- Future-proofs SEO: Google has gradually placed more emphasis on HTTPS as a ranking factor. Migrating to HTTPS now future-proofs your site as this trend continues.
Overall, implementing a proper SSL certificate and redirecting to HTTPS can provide modest SEO gains. It also avoids any penalties sites may incur in the future for not being secure. Along with the security and privacy benefits, SSL certificates are worthwhile for SEO.
HTTP vs. HTTPS for SEO
The main difference between HTTP and HTTPS is that HTTPS uses SSL encryption to provide a secure connection. This has several benefits for SEO:
- HTTPS is more secure – Google wants to provide the most secure experience for users, so it favors HTTPS sites in search rankings. HTTP sites are seen as less secure.
- Improves user experience – Users feel more comfortable entering data and conducting transactions on HTTPS sites. This improves engagement metrics like time on site, pages per session, and bounce rate.
- Builds trust – The padlock icon shows users the site is secure. This establishes credibility and trust with visitors.
- Future-proofs your site – Google has already started giving ranking boosts to HTTPS sites. As more sites transition to HTTPS, those without it could be penalized. Moving to HTTPS now will prevent issues.
- Positive ranking signal – Although not the only factor, Google has confirmed HTTPS is a lightweight ranking signal. All other factors being equal, HTTPS sites may get a slight boost.
The best practice is to switch your site to HTTPS if you haven’t already. The process is relatively quick and there are many affordable SSL certificate options. The SEO and user experience benefits make it worthwhile. Migrating to HTTPS shows Google you prioritize security and trust.
Best Practices for SSL Implementation
When implementing SSL certificates on your website, it’s important to follow best practices to ensure proper security and maximum SEO benefit. Here are some key best practices to keep in mind:
Choose a Reputable Certificate Authority
Your SSL certificate should be issued by a trusted, reputable CA (certificate authority). Companies like Comodo, DigiCert, GeoTrust, and Symantec are leading CAs with strong reputations. Avoid cheap or unknown CAs, as their certificates may not be trusted by all browsers and users. Stick to well-known CAs for the best compatibility and trust. If you are unsure, you may contact Adssential Marketing or any agency that does website, they would be able to assist you in this matter.
Keep Certificates Updated
Make sure to renew your SSL certificate before it expires. An expired cert will cause security warnings for site visitors. Set a reminder to renew your certificate at least 1 month prior to expiration. Also replace certificates if their encryption strength becomes outdated.
Implement HSTS
Enable HTTP Strict Transport Security (HSTS) on your web server. This instructs browsers to only connect via HTTPS for a set period of time. It prevents man-in-the-middle attacks that try to downgrade HTTPS to plain HTTP.
Use OCSP Stapling
Enable Online Certificate Status Protocol (OCSP) stapling on your server. This speeds up the SSL certificate verification process by “stapling” your latest OCSP status to the cert. The browser doesn’t have to contact the CA separately to check revocation status.
Following these best practices will maximize your site’s security and prevent issues with your SSL implementation. Keep your certificates up-to-date, use trusted CAs, and enable advanced options like HSTS and OCSP stapling. This will ensure optimal performance and trust for your HTTPS site.
SSL Myths and Misconceptions
While SSL certificates provide many benefits, there are some common myths and misconceptions about what they can and can’t do.
Myth: SSL certificates guarantee higher search rankings
Reality: Google has stated that switching to HTTPS will not directly improve your rankings. SSL protects your site and users, which is worthwhile on its own merits. But it does not give you an automatic rankings boost. Good content and user experience are still the main ranking factors.
Myth: The green padlock icon means you’re 100% secure
Reality: The padlock provides a visual cue that encryption is in place between the browser and server. However, it does not guarantee the legitimacy or security of the site itself. Always look for trusted seals from certificate authorities as additional verification.
Myth: Non-HTTPS sites will be penalized by Google
Reality: While Google is encouraging HTTPS adoption, they have said HTTPS is not a direct ranking factor. Non-secure sites will not be automatically penalized. However, HTTPS provides other benefits like security and trust that are worthwhile for users.
Myth: SSL certificates are only for ecommerce sites
Reality: All websites can benefit from SSL encryption. It protects login pages, contact forms, and any sensitive user data submitted. So both informational and ecommerce sites should adopt SSL.
The main takeaway is that SSL certificates provide encryption and legitimacy, which builds user trust. But they should not be viewed as a “quick fix” for other issues like poor content quality or user experience. SSL contributes to a secure, trustworthy site, but proper implementation and smart SEO remain important.
Conclusion on SSL Installation Certificates
SSL certificates are an important aspect of website security and search engine optimization. Proper SSL installation provides encryption to protect user data and reassure visitors. It also gives a slight SEO ranking boost by switching the site to HTTPS.
The main steps for installing an SSL cert are purchasing, generating a CSR, receiving issued cert, installing on the server, and updating site references to HTTPS. Common errors like missing intermediate certs, incorrect setup, and mixed content need to be avoided.
For SEO, HTTPS shows Google a commitment to security and trust. It prevents keyword sniffing as well. However, switching to SSL doesn’t guarantee higher rankings on its own. Focus on creating quality content rather than obsessing over HTTP vs HTTPS.
In summary, install SSL properly with attention to detail. Use it ethically as part of an overall SEO strategy, not as a quick fix. SSL helps provide a more secure and positive user experience. But always keep the focus on great content, site speed, mobile optimization, and other core web vitals for the best SEO results. When in doubt, you may engage an agency to understand more on SSL as well.
