What Is an SSL Certificate? Why Every Website Needs HTTPS

The padlock in the address bar comes from an SSL certificate. Without it, browsers warn visitors your site is "Not secure". Here is what SSL is and how to get it right.

  13. Summary

When you open a website, you will often see a small padlock next to the address. That padlock means the site uses an SSL certificate and loads over HTTPS. Without it, Chrome and other browsers show a "Not secure" warning – which scares visitors away. This guide explains what an SSL certificate does and how to set it up correctly.

What an SSL certificate does

An SSL certificate (technically TLS today) does two things:

  1. Encrypts the connection between the visitor's browser and your website, so nobody in between can read passwords, form details or payment information.
  2. Proves the website's identity, so visitors know they are talking to your real site.

When SSL is active, your address starts with https:// instead of http://.

Why every website needs an SSL certificate

  • Trust: visitors see a padlock instead of a "Not secure" warning.
  • Security: contact forms, logins and checkouts are protected.
  • SEO: Google uses HTTPS as a ranking signal and prefers secure pages.
  • Required for features: online payments, many browser features and modern web technologies need HTTPS.

Even a simple brochure website with a contact form should use HTTPS.

Types of SSL certificate

TypeChecksGood for
Domain Validated (DV)You control the domainMost business websites, blogs, stores
Organisation Validated (OV)Domain + company detailsCompanies that want extra verification
Extended Validation (EV)Strict company checksBanks and large enterprises
WildcardCovers all subdomainsSites with many subdomains

For most small and medium businesses, a free DV certificate (such as Let's Encrypt) is perfectly secure – the encryption is the same strength.

How to install an SSL certificate

  1. Make sure your domain points to your hosting.
  2. Activate SSL from your hosting control panel (many hosts do it automatically).
  3. Update your website address to https:// (in WordPress: Settings → General).
  4. Redirect all http:// traffic to https:// so visitors and Google always use the secure version.
  5. Fix "mixed content" – images or scripts still loaded over http://.

SSL certificate renewal

Free certificates usually last 90 days and renew automatically. Paid ones last up to a year. Expired certificates show a full-page warning to visitors, so make sure renewal is automatic and monitored.

Common SSL problems

  • "Not secure" even with SSL: some images or scripts still load over http. Replace them with https links.
  • Certificate name mismatch: the certificate does not cover www or a subdomain. Reissue it for all names you use.
  • Redirect loops: conflicting redirect settings in the site and the server. Keep one redirect rule.

HTTPS and website speed

Modern HTTPS (with HTTP/2 or HTTP/3) is not slower – it is often faster than plain HTTP. Combine SSL with the tips in our website speed guide for the best results.

Frequently asked questions

Is a free SSL certificate safe?

Yes. Free certificates such as Let's Encrypt use the same strong encryption as paid ones. Paid certificates add extra company validation or warranties, which most small businesses do not need.

Does an SSL certificate improve Google rankings?

HTTPS is a confirmed, light ranking signal, and Chrome warns visitors about sites without it. More importantly, it builds trust, which affects whether visitors stay and contact you.

How do I know if my SSL certificate is working?

Open your site with https:// and look for the padlock in the address bar. Click it to see who issued the certificate and when it expires. Also check that http:// redirects to https:// automatically.

Do I need a separate SSL certificate for www?

Your certificate must cover every name you use – yourbrand.in and www.yourbrand.in. Most hosting panels include both automatically, but check if you see a name mismatch warning.

Summary

An SSL certificate encrypts your visitors' data, removes browser warnings, supports online payments and helps your Google ranking. Use HTTPS on every page, redirect http to https and make sure renewal is automatic.

All websites on our web hosting can run on HTTPS with SSL managed from the control panel. Ask us if you need help moving your site to HTTPS.
