SSL for webshops: why an SSL certificate is essential

For every webshop, an SSL certificate is not optional - it's an absolute necessity. SSL (Secure Sockets Layer) encrypts the communication between your customers and your web server, keeping sensitive information like credit card details and personal data secure. In this article, we explain why SSL is essential and what type of certificate you need.

Why SSL is crucial for webshops

Trust and conversion

• Padlock icon builds customer trust
• "Not secure" warning scares customers away
• Higher conversion rates with HTTPS
• Professional appearance

Legal requirements

• GDPR requires data protection
• Payment processors require SSL
• PCI-DSS compliance requires encryption

SEO benefits

• Google favors HTTPS sites
• Better rankings in search results
• Required for many Google features

Payment processing

• All payment providers require SSL
• iDEAL, credit cards, PayPal
• Cannot process payments without it

Types of SSL for webshops

Domain Validation (DV)

Basic encryption

• Validates domain ownership only
• Issued within minutes
• Free via Let's Encrypt
• Sufficient for small shops

Organization Validation (OV)

Business verification

• Validates company exists
• Shows company name in certificate
• 1-3 days for issuance
• €50-200/year

Extended Validation (EV)

Highest trust level

• Extensive company verification
• Formerly showed green bar
• Most trusted by consumers
• €150-500/year

Which certificate for your webshop?

Small webshop (starting out)

Recommendation: Free DV (Let's Encrypt)

• Encryption is identical
• Zero cost
• Automatic renewal
• Sufficient for most shops

Growing webshop

Recommendation: DV or OV

• DV is usually sufficient
• OV if you want company validation
• Consider based on transaction values

Large webshop / enterprise

Recommendation: OV or EV

• Company validation shows legitimacy
• Required for some B2B
• Consider insurance/warranty

Setting up SSL for your webshop

Step 1: Obtain certificate

Most hosting includes free SSL:

• Let's Encrypt (automatic)
• Control panel activation
• Usually one-click setup

Step 2: Configure webshop

• Update WordPress/WooCommerce URLs to HTTPS
• Update internal links
• Configure 301 redirects

Step 3: Update external services

• Payment provider settings
• Analytics tracking codes
• Email service configurations

Step 4: Test thoroughly

• Check all pages load via HTTPS
• Test checkout process
• Verify no mixed content warnings

Common SSL mistakes with webshops

1. Mixed content

HTTP resources on HTTPS pages. Fix by updating all URLs to HTTPS.

2. Forgetting redirects

Both HTTP and HTTPS accessible. Add 301 redirects to force HTTPS.

3. Certificate expiration

Let's Encrypt expires every 90 days. Ensure auto-renewal works.

4. Wrong certificate type

Wildcard needed for subdomains. Check coverage before buying.

5. Not testing checkout

SSL issues often appear in payment flows. Test complete purchase process.

SSL and payment providers

iDEAL

• Requires valid SSL
• Any DV/OV/EV works
• Must be active before integration

Credit cards (Stripe, Mollie)

• SSL mandatory
• Recommend EV for high-value transactions
• PCI-DSS compliance related

PayPal

• Requires HTTPS checkout
• Works with any valid SSL
• Additional security checks

Our recommendation

For most webshops, free Let's Encrypt SSL is sufficient. The encryption is identical to paid certificates, and it's included with most hosting providers.

Consider paid certificates only when:

• You need warranty/insurance
• B2B clients expect company validation
• Very high transaction values
• Compliance requirements demand it
