SSL certificate: why does a website need it and how does it affect trust and SEO
The Internet is developing rapidly, and users are increasingly paying attention to online security. One of the main indicators of a secure website is the presence of an SSL certificate. If earlier this was considered an additional option, today it is a mandatory standard for any resource.
What is an SSL certificate?
SSL (Secure Sockets Layer) – is a data encryption technology that provides a secure connection between the site and the user.
How can you tell if a site is secure? A site with SSL has an address that starts with https://, and a “lock” icon is displayed in the browser. This means that the visitor’s data (passwords, card numbers, personal information) is protected from interception.
Why does a site need an SSL certificate?
1. Protection of user data
Any form on the site (registration, order, feedback) transmits information. SSL encrypts this data, eliminating the risk of theft.
2. Customer trust
The visitor sees the “lock” and https:// and understands that this is a serious site that can be trusted. If the “Insecure connection” warning appears, most users will simply close the page.
3. SEO promotion
Search engines take into account the presence of SSL. Google has directly stated that sites with a secure connection receive an advantage in search results.
4. Online payments
If you accept payments on the site, SSL is required. Banking systems and payment services do not work with unsafe resources.
What types of SSL certificates are there?
- DV (Domain Validation) is the simplest and cheapest. It only confirms domain ownership.
- OV (Organization Validation) – additionally confirms the organization’s data.
- EV (Extended Validation) – the highest level of trust, a green line with the company name is displayed in the browser.
How to install an SSL certificate?
- Many hosting providers provide free SSL (for example, Let’s Encrypt)
- For business, you can purchase a paid certificate from certified centers.
- Installation is usually performed through the hosting panel or CMS admin panel.
It seems that an SSL certificate is just a small detail, because the address of a secure and unsecured site is only one letter away. But in fact, it is the most important element of a modern site. It protects user data, increases trust in your brand and helps promote in search engines.
If your site still does not have an SSL certificate, you should fix it right now.
