What Does HTTPS Mean and Why Does Your Website Need SSL?

Introduction

Most people have seen the difference between a website address beginning with http:// and one beginning with https://.

The extra “s” stands for secure.

That small difference represents an important layer of protection between a visitor’s browser and the website they are using.

HTTPS helps encrypt information being exchanged with the website and allows the browser to verify that it is communicating with the server associated with the domain.

For businesses investing in website design Osborne Park, HTTPS should be considered a basic website requirement rather than an optional technical upgrade.

It is important for security, customer confidence, modern browser behaviour and the overall reliability of the website.

You will also often hear people refer to an “SSL certificate”. Strictly speaking, modern websites use TLS rather than the older SSL protocols, but the term SSL certificate remains widely used in the website industry.

What Does HTTPS Mean?

HTTPS stands for Hypertext Transfer Protocol Secure.

HTTP is the protocol used to transfer information between a web browser and a web server.

HTTPS adds encryption and authentication to that communication using TLS.

In simple terms, HTTPS helps create a protected connection between the visitor and the website.

A secure website address looks like this:

https://www.example.com/

rather than:

http://www.example.com/

That does not mean the entire website is automatically safe from every possible security problem.

It means the connection used to communicate with the website is encrypted and authenticated.

What Is an SSL Certificate?

An SSL certificate is the commonly used name for the digital certificate that helps a website establish an HTTPS connection.

Modern certificates are more accurately described as TLS certificates, but “SSL certificate” remains the familiar industry term.

The certificate contains information such as:

• the domain name it applies to
• the certificate authority that issued it
• the certificate’s validity period
• the public key used as part of the secure connection

When a visitor connects to the website, the browser can use this information to help verify that it is communicating with the correct server and establish an encrypted connection.

Cloudflare provides a good technical overview here: What is an SSL certificate?.

SSL and TLS Are Not Exactly the Same Thing

The terms SSL and TLS are often used interchangeably, but they are not technically identical.

SSL stands for Secure Sockets Layer.

TLS stands for Transport Layer Security.

TLS replaced the older SSL protocols and is the technology modern HTTPS connections use.

When a hosting company, web developer or certificate provider talks about “SSL” today, they are usually referring broadly to the certificate and secure TLS setup required for HTTPS.

This is why terms such as:

• SSL certificate
• SSL security
• SSL/TLS
• TLS certificate

may all appear when discussing secure websites.

What Does HTTPS Actually Protect?

HTTPS encrypts information while it travels between the visitor’s browser and the website.

This can include:

• contact form submissions
• login credentials
• account information
• checkout information
• search queries
• page requests

Without encryption, network traffic may be easier for an attacker in a suitable position to inspect or interfere with.

HTTPS helps protect the communication from being read or altered while it is travelling between the visitor and the website.

Encryption Does Not Mean the Website Cannot Be Hacked

This distinction is important.

HTTPS protects the connection.

It does not automatically protect the website from:

• vulnerable WordPress plugins
• weak passwords
• malware
• compromised administrator accounts
• poor server configuration
• outdated software
• insecure third-party integrations

A website can have a perfectly valid SSL certificate and still have serious security problems elsewhere.

HTTPS is one layer of website security, not the entire security strategy.

Our article Website Security for Small Businesses: What Your Website Provider Should Be Looking After explains the broader protections a business website needs.

HTTPS Helps Protect Contact Forms

Even a simple business website may collect personal information.

A contact form may ask for:

• name
• email address
• telephone number
• company
• details of an enquiry

That information should not be sent through an unencrypted website connection.

HTTPS helps protect the form submission while it travels between the visitor and the web server.

That does not remove the need to handle the information securely after it reaches the website or associated systems.

Our article What Personal Information Does Your Business Website Collect? looks at the wider information-handling issues.

HTTPS Is Essential for Ecommerce

For an ecommerce website, HTTPS is fundamental.

Customers may be:

• creating accounts
• entering names and addresses
• signing in
• submitting order details
• moving between the store and payment provider

Modern payment gateways typically handle card information through their own secure systems, but the ecommerce website itself still needs secure communication throughout the shopping and checkout journey.

An online store that does not use HTTPS would create immediate security and trust concerns.

Browsers Expect Websites to Use HTTPS

HTTPS is now the normal standard for modern websites.

Browsers distinguish between secure and insecure connections and may warn users when a site uses plain HTTP.

Even visitors who do not understand the technical difference can react negatively if the browser suggests that a website is not secure.

For a business website, that can damage credibility before the visitor has even read the page.

A professional website should not create uncertainty about whether it is safe to use.

The Padlock Is Not a Guarantee That a Business Is Trustworthy

Historically, people were often told to look for a padlock icon as proof that a website was safe.

That advice needs more context today.

HTTPS confirms that the connection is encrypted and that the certificate is valid for the website being visited.

It does not prove that:

• the business is reputable
• the products are genuine
• the website has not been compromised
• the company will provide good service
• the offer is not a scam

Malicious websites can also obtain valid certificates.

Visitors should therefore assess the wider credibility of the website as well.

HTTPS Supports Website Credibility

Although HTTPS cannot prove that a business is trustworthy, the absence of HTTPS can certainly undermine confidence.

A potential customer may hesitate to:

• submit a form
• create an account
• make a purchase
• enter personal details

if the browser indicates that the connection is insecure.

For businesses seeking web design Osborne Park, HTTPS should therefore be part of the overall user experience and credibility strategy, not simply a server setting hidden from visitors.

Does HTTPS Help SEO?

HTTPS has been used by Google as a ranking signal for many years.

However, businesses should not migrate to HTTPS because they expect a dramatic ranking increase.

The main reason to use HTTPS is to provide a secure, modern website experience.

Search visibility is influenced by many other factors, including:

• useful content
• relevance
• site structure
• internal links
• local relevance
• page experience
• authority

HTTPS should be considered part of the technical foundation of a good website rather than an SEO trick.

A Certificate Must Match the Domain

An SSL/TLS certificate is issued for specific domain names.

For example, a website may need coverage for:

• example.com
• www.example.com
• shop.example.com

If a visitor reaches a hostname that is not covered correctly by the certificate, the browser may display a certificate warning.

This is one reason certificate configuration needs to match the real DNS and website setup.

Certificates Have Expiry Dates

Certificates are issued for a limited period.

They therefore need to be renewed.

Modern hosting platforms and certificate authorities can automate much of this process.

Let’s Encrypt, for example, uses the ACME protocol to automate domain validation, certificate issuance and renewal.

You can read more here: How Let’s Encrypt works.

Automatic renewal greatly reduces manual administration, but the system should still be monitored.

A failed renewal can eventually lead to browser warnings if the certificate expires.

Free Certificates Can Provide Strong Encryption

A business does not necessarily need to purchase an expensive certificate to have a properly encrypted website.

Free certificate authorities such as Let’s Encrypt provide browser-trusted certificates, while platforms such as Cloudflare can also provide managed certificates.

The cost of a certificate is not a direct measure of the strength of the HTTPS encryption.

Different certificate products may offer different validation, management or commercial features, but a free certificate can still provide the secure connection required by a normal business website.

Domain Validation Does Not Verify the Whole Business

Many modern website certificates use domain validation.

This means the certificate authority verifies that the person or system requesting the certificate has control over the domain.

That is different from independently verifying every aspect of the organisation operating the website.

This reinforces why visitors should not interpret the presence of HTTPS as proof that a business itself has been fully vetted.

Cloudflare Can Manage HTTPS at the Edge

When a website uses Cloudflare, visitors may connect first to Cloudflare rather than directly to the origin web server.

Cloudflare can provide an edge certificate for that visitor connection.

There can then be a second connection between Cloudflare and the origin server.

This means a Cloudflare-protected website can effectively involve two secure connections:

• visitor to Cloudflare
• Cloudflare to the origin server

Cloudflare’s current documentation explains that both connections should be encrypted for end-to-end protection.

You can read the guidance here: Enforce HTTPS and encrypt all traffic.

Cloudflare SSL Modes Matter

Using Cloudflare does not automatically mean every connection behind it is configured in the same way.

The SSL/TLS encryption mode determines how Cloudflare connects to the origin server.

A properly configured site should provide secure communication through the full path rather than encrypting only the visitor-facing portion.

For websites using Cloudflare, certificate setup and origin-server configuration therefore need to work together.

Redirect HTTP Visitors to HTTPS

Installing a valid certificate is only part of the process.

If the website still responds separately over plain HTTP, visitors may continue reaching the insecure version.

A normal HTTPS setup should redirect requests such as:

http://example.com/page/

to:

https://example.com/page/

This ensures visitors and search engines consistently use the secure version.

Cloudflare also recommends enforcing HTTPS even after an edge certificate has been activated. citeturn746776search3

Choose One Canonical Website Address

HTTPS migration is also a good time to ensure the website has a consistent canonical hostname.

For example, the site might use:

https://www.example.com/

as its preferred version.

Other versions such as:

• http://example.com/
• http://www.example.com/
• https://example.com/

can then redirect to the preferred address.

This provides visitors and search systems with one consistent website location.

Mixed Content Can Break an HTTPS Migration

A page can load over HTTPS while still requesting individual files over HTTP.

This is known as mixed content.

Examples may include:

• images
• stylesheets
• JavaScript
• embedded resources
• fonts

Browsers may block insecure resources or display security concerns.

This can lead to:

• missing images
• broken layouts
• scripts failing
• security warnings

A proper HTTP-to-HTTPS migration should therefore check internal URLs and embedded resources rather than simply installing the certificate.

Old WordPress URLs Can Cause Mixed Content

WordPress websites that have existed for many years may contain older absolute URLs inside:

• page-builder content
• media references
• theme settings
• custom fields
• widgets

If those references still use http://, the site may need a careful database update or configuration change.

This should be handled carefully because indiscriminate database replacement can damage serialized or structured data on older websites.

HTTPS Should Be Considered During Website Migration

Moving a website between servers or hosting providers can affect certificates, redirects and DNS.

A migration plan should check:

• certificate issuance
• DNS configuration
• HTTP redirects
• canonical URLs
• mixed content
• Cloudflare settings
• Search Console configuration where relevant

Our article Planning a Website Migration Without Losing Important Search Visibility covers the wider migration process.

HTTPS Does Not Encrypt Everything Everywhere

HTTPS protects information while it travels across the encrypted connection.

Once information reaches the website or another system, it still needs to be stored and handled appropriately.

For example, HTTPS does not automatically determine:

• how contact form entries are stored
• who has administrator access
• whether databases are encrypted at rest
• how email is protected
• how backups are secured

Those are separate security and privacy considerations.

HTTPS Does Not Protect Email After a Form Is Submitted

A common example is a website contact form.

HTTPS can protect the information as the visitor submits the form to the website.

If the website then sends that information by email, the security of the next stage depends on the mail systems involved.

This is one reason businesses should think about the complete information flow rather than assuming HTTPS solves every privacy concern.

Certificate Warnings Should Be Treated Seriously

A browser may warn visitors if:

• the certificate has expired
• the domain name does not match
• the certificate chain is invalid
• the certificate authority is not trusted

Website owners should not tell visitors simply to ignore these warnings.

The cause should be investigated and corrected.

A certificate warning can stop visitors from reaching the website entirely and can seriously damage trust.

Certificate Renewal Should Be Monitored

Automated certificate renewal is extremely reliable when configured correctly, but failures can still happen.

Possible causes include:

• DNS changes
• domain expiry
• incorrect validation records
• server changes
• firewall rules
• misconfigured redirects

A managed website environment should monitor certificate health so that expiry problems can be addressed before visitors are affected.

Domain Expiry Can Affect HTTPS Too

A certificate cannot rescue a domain that is no longer properly registered or controlled.

If the domain expires or its DNS stops resolving correctly, certificate validation and renewal may eventually fail as well.

This is another reason domain ownership and renewal should be actively managed.

Our article Who Owns and Controls Your Business Domain Name? explains why domain administration should not be overlooked.

HTTPS Should Cover the Entire Website

Years ago, some websites used HTTPS only for login or checkout pages.

That approach is no longer appropriate for a normal modern website.

The whole site should generally use HTTPS, including:

• home page
• service pages
• blog articles
• contact pages
• customer portals
• checkout
• administration areas

This provides consistent security and avoids unnecessary switching between protocols.

Subdomains Need Appropriate Certificate Coverage

A business may operate several web services under one domain.

For example:

• www.example.com
• shop.example.com
• portal.example.com
• members.example.com

Each relevant hostname needs appropriate certificate coverage.

This may be handled with separate certificates, multi-domain certificates, wildcard certificates or managed platform certificates depending on the infrastructure.

Wildcard Certificates Have a Specific Purpose

A wildcard certificate can cover multiple first-level subdomains under a domain.

For example:

*.example.com

might cover:

• shop.example.com
• portal.example.com
• members.example.com

It does not mean the certificate automatically covers every possible hostname structure or unrelated domain.

Certificate choice should match the actual infrastructure rather than simply choosing the option that sounds most comprehensive.

HTTPS and Website Performance

Website owners sometimes worry that encryption will make a website noticeably slower.

Modern HTTPS and TLS are designed for widespread use, and secure connections are now a normal part of high-performance web delivery.

Cloudflare also optimises SSL/TLS connections across its network and provides HTTPS as part of its normal platform services.

Website performance problems are far more likely to come from issues such as:

• oversized images
• poor hosting
• heavy JavaScript
• third-party scripts
• uncached dynamic pages
• slow database queries

rather than the simple fact that HTTPS is enabled.

HTTPS Is Only One Part of Technical Website Health

A technically healthy website also needs:

• reliable hosting
• current software
• backups
• malware protection
• secure administrator accounts
• working DNS
• correct redirects
• good performance

HTTPS forms an essential foundation, but the surrounding systems still need to be managed properly.

What Should a Small Business Owner Check?

You do not need to understand cryptography to check the basics.

Start by confirming that:

• your website loads using https://
• HTTP versions redirect to HTTPS
• the browser does not display certificate warnings
• your main domain and www version resolve correctly
• contact forms work
• checkout works if applicable
• important images and scripts load correctly
• the certificate renews automatically

If the site uses Cloudflare, also confirm that encryption is configured appropriately between Cloudflare and the origin server.

What If the Website Still Uses HTTP?

An existing HTTP website should generally be migrated to HTTPS rather than left as it is.

The process may involve:

• obtaining a certificate
• configuring the web server
• updating WordPress URLs
• redirecting HTTP traffic
• fixing mixed content
• reviewing canonical tags
• checking internal links
• testing forms and integrations

On a very old website, it is worth testing carefully because there may be legacy resources or plugins that assume HTTP URLs.

Do You Need to Pay for an SSL Certificate?

For many normal small business websites, no.

Reliable free certificates are widely available through services such as Let’s Encrypt and Cloudflare.

A paid certificate may still be appropriate in particular environments where an organisation requires specific certificate management, validation, warranty or enterprise features.

But businesses should not assume that an expensive certificate automatically means stronger encryption for an ordinary website.

Should SSL Be Included With Website Hosting?

In a modern managed hosting environment, HTTPS certificate management should normally be part of the basic hosting service.

A business owner should not need to manually purchase and reinstall a basic certificate every year simply to keep an ordinary website secure.

For businesses using managed web development Osborne Park and hosting services, certificate issuance, renewal and HTTPS enforcement should generally be handled as part of the technical environment.

HTTPS Is Now a Basic Website Requirement

HTTPS is no longer something reserved for banks, online stores or websites handling highly sensitive information.

Every normal business website should use it.

It helps:

• encrypt traffic
• authenticate the server
• protect form submissions in transit
• avoid browser security warnings
• support customer confidence
• provide a modern technical foundation

It does not make a website immune from hacking, remove the need for maintenance or prove that the business itself is trustworthy.

It is one essential layer within a broader website security strategy.

For businesses looking for web design Osborne Park, website design Osborne Park or web development Osborne Park support, HTTPS should be correctly configured from the beginning and maintained throughout the life of the website.
