HTTPS encrypts all data traveling between the user's browser and your server; HTTP sends it in plain text, readable by anyone who intercepts the connection. If your site still runs on HTTP, you're exposing visitors and leaving SEO points on the table.
What Is HTTP and What Is HTTPS?
HTTP (HyperText Transfer Protocol) is the foundational protocol that defines how web pages are requested and delivered — it has been in use since 1991. It operates over TCP/IP and includes no encryption mechanism whatsoever.
HTTPS (HTTP Secure) is the same protocol with a security layer on top: TLS (Transport Layer Security, the successor to SSL). That layer guarantees three things:
- Confidentiality: data travels encrypted; an interceptor sees only unreadable ciphertext.
- Integrity: data cannot be altered in transit without the browser detecting it.
- Authentication: the SSL certificate verifies that the server is genuinely who it claims to be.
The most visible difference is in the URL: http:// versus https://, plus the padlock icon in the browser address bar.
Key Technical Differences Between HTTP and HTTPS
| Feature | HTTP | HTTPS |
|---|---|---|
| Default port | 80 | 443 |
| Encryption | None | Yes (TLS 1.2 / 1.3) |
| Certificate required | No | Yes (SSL/TLS) |
| Raw speed | Slightly faster without handshake | HTTP/2 + TLS 1.3 close the gap |
| Chrome security indicator | "Not secure" warning | Padlock / neutral |
| Google ranking signal | Negative | Positive tiebreaker |
Why HTTPS Matters for SEO
Google confirmed in 2014 that HTTPS is a ranking factor. Its weight has grown since then. Today it acts as a tiebreaker: between two equally relevant pages, the HTTPS version wins positions.
But the impact goes beyond the algorithm:
- Referral data in Google Analytics: when a user arrives at your HTTP site from an HTTPS site, the browser strips the referrer — that traffic appears as "direct" and you lose marketing intelligence.
- Core Web Vitals and page load: HTTP/2 (which requires HTTPS in all modern browsers) parallelizes requests and speeds up loading, improving metrics like LCP.
- User trust and conversion rate: Chrome displays "Not secure" on HTTP sites. That warning spikes form and cart abandonment.
- Requirement for modern browser features: geolocation, push notifications, camera and microphone access work only in secure contexts (HTTPS).

How to Migrate from HTTP to HTTPS Without Hurting SEO
A poorly executed migration can cost rankings even when the destination is HTTPS. Follow these steps:
- Install a valid SSL certificate. Let's Encrypt offers free certificates; quality hosting plans include them already activated.
- Redirect all HTTP traffic → HTTPS with 301 redirects at the server level (Apache:
RewriteRule; Nginx:return 301). Never use 302. - Update internal URLs and resources (images, CSS, JS, fonts) to
https://to avoid mixed content that breaks the padlock. - Update your sitemap and robots.txt with HTTPS URLs.
- Re-verify the property in Google Search Console under the HTTPS prefix and request indexing.
- Enable HSTS (HTTP Strict Transport Security) in server headers so browsers always remember to use HTTPS.
A specialized team can complete this migration in just a few hours. At elenlace.com we guide our clients through every step, from certificate installation to post-migration verification.
How Much Does an SSL Certificate Cost?
| Type | Validation | Approximate cost | Best for |
|---|---|---|---|
| DV (Domain Validation) | Domain only | Free – $12 USD/year | Blogs, portfolios, landing pages |
| OV (Organization Validation) | Company + domain | $50 – $200 USD/year | Corporate sites |
| EV (Extended Validation) | Thorough verification | $100 – $500 USD/year | Banking, large e-commerce |
| Wildcard DV | Domain + * subdomains | $70 – $300 USD/year | Multiple subdomains |
For most sites, a DV certificate (included in many hosting plans) is all you need.
Key Takeaways
- HTTP sends data in plain text; HTTPS encrypts it with TLS, protecting the privacy and integrity of the connection.
- Google has used HTTPS as a positive ranking signal since 2014, and Chrome labels HTTP sites "Not secure."
- A correct migration requires 301 redirects, resource URL updates, and re-verification in Search Console.
- DV certificates are free (Let's Encrypt) and sufficient for the vast majority of websites.
- HTTPS enables HTTP/2, improves Core Web Vitals, and preserves referral data in Analytics.

FAQ
What is the main difference between HTTP and HTTPS?
HTTPS adds a TLS encryption layer on top of HTTP. This means data travels encrypted between the browser and server, while HTTP sends it in plain text where it can be intercepted and read by third parties.
Does HTTPS affect site speed?
The TLS handshake adds a small initial latency, but in practice HTTPS is equal to or faster than HTTP because it enables HTTP/2, which multiplexes multiple requests over a single connection. With TLS 1.3, the handshake is reduced to a single round trip.
Do I need HTTPS if my site doesn't sell anything?
Yes. Even a blog or portfolio without payment forms benefits: Google ranks it better, Chrome doesn't show the "Not secure" warning, and Analytics data is more accurate. Additionally, many browser features (geolocation, service workers) only work over HTTPS.
Can migrating to HTTPS temporarily drop my rankings?
With a correct migration (301 redirects, sitemap updates, Search Console re-verification), the impact is minimal and transient — typically less than two weeks. Without 301 redirects, Google treats the HTTP and HTTPS versions as duplicate content and significant ranking losses can occur.
