SSL Certificate (HTTPS) - What It Is and Why It's Essential

Security·3 min read

An SSL certificate is what turns a site's address from http into https and shows the padlock in the browser. It encrypts the connection between the user and the site - and today it's a standard, not a luxury.

What it actually gives you

It encrypts data sent through the site (e.g., from forms), so no one along the way can eavesdrop on it. It also builds trust - a site without the padlock scares people off with a "Not secure" warning.

Impact on SEO and trust

Google treats HTTPS as a signal and flags sites without SSL as unsafe, which drives visitors away. A missing certificate can genuinely reduce the number of inquiries.

How much it costs

Often nothing - a basic certificate can be free and included with hosting. It's worth making sure the site has one from day one.

In brief

  • SSL = the padlock and https, meaning an encrypted, secure connection.
  • No SSL scares customers off and hurts SEO.
  • It's usually free - and should be there from the start.
