Since 2018 Google has used HTTPS as a ranking factor and Chrome shows "Not secure" on every site that does not use it. 85% of web users leave a site that displays that warning, and the figure rises to 95% for e-commerce sites and contact forms. If your site is still on HTTP in 2026, you are losing Google rankings and customers, every single day.
The good news: SSL certificates have been free since 2016 thanks to Let's Encrypt, and the move from HTTP to HTTPS takes under an hour on most hosting. This guide explains why it is urgent and how to do it without losing your rankings.
Why is HTTPS essential in 2026?
1. A direct Google ranking signal
Google officially confirmed HTTPS as a ranking signal back in 2014. In 2026, with billions of sites on HTTPS, those still on HTTP are clearly penalised in search results. In a competitive market, having no SSL certificate automatically puts you behind every secured competitor.
2. An immediate loss of trust and conversions
Chrome, Safari and Firefox show a "Not secure" warning on HTTP sites, in red in the address bar, sometimes with a full alert page before the visitor can reach the site. The result: 85% of visitors leave without even seeing your content, and the figure rises to 95% on pages with contact or payment forms.
3. A GDPR obligation
Sending personal data over HTTP (names, emails, passwords, card numbers) without encryption is a clear GDPR breach and exposes you to CNIL penalties. Any contact form on an HTTP site is legally problematic.
4. Access to modern protocols
HTTP/2 and HTTP/3, which speed up loading significantly by multiplexing requests, both require HTTPS. Without SSL your site is stuck on HTTP/1.1, the slowest version, which hits your Core Web Vitals and your PageSpeed score directly.
HTTP vs HTTPS compared:
| Criterion | HTTP | HTTPS |
|---|---|---|
| Data encryption | None | TLS 1.3 |
| Google SEO factor | Penalised | Positive signal |
| Chrome display | "Not secure" in red | Secure padlock |
| Visitor trust | Very low | High |
| Forms / payments | Data can be intercepted | Encrypted end to end |
| HTTP protocol available | HTTP/1.1 only | HTTP/2 + HTTP/3 |
| GDPR | Non-compliant with personal data | Compliant |
Which type of SSL certificate should you choose?
There are 3 levels of SSL certification, each with its own use case:
DV, Domain Validation (free)
Only proves that you control the domain. Supplied free by Let's Encrypt and renewed automatically every 90 days. Recognised by 100% of browsers. Best for: brochure sites, blogs, portfolios, small business sites, landing pages. This is the certificate you should be using: 95% of websites need nothing more.
OV, Organization Validation (50 to 200€ a year)
Validates the domain AND the legal existence of the company (Kbis extract, phone verification). Offers visitors slightly stronger assurance. Best for: e-commerce, sites with a customer area, B2B.
EV, Extended Validation (200 to 490€ a year)
Full validation with an in-depth legal check. It used to show the company name in green in the address bar (Chrome removed that display in 2019). Best for: banks, insurers, financial institutions.
Let's Encrypt in practice:
A free, open source certificate authority backed by Mozilla, Google, Microsoft and Cisco. Available automatically on Vercel (included, zero configuration), Netlify (included), OVH (control panel), PlanetHoster and Infomaniak. In 2026 every professional host includes it, and if yours does not, that is your signal to move.
How do you migrate your site from HTTP to HTTPS without losing rankings?
Moving from HTTP to HTTPS is simple, but it has to follow a precise order so you do not break your SEO.
Step 1, Install the SSL certificate
Step 2, Set up the 301 redirects
Every HTTP URL must redirect permanently (code 301) to its HTTPS equivalent. That is what passes your pages' "PageRank" to the new version. Set it in the .htaccess file (Apache) or nginx.conf (Nginx). Check it with Redirect Checker (free tool).
Step 3, Update your internal links
Replace http:// with https:// everywhere: in your database (WordPress: the Velvet Blues or Better Search Replace plugin), in your CSS and JS files, in embedded image URLs and in your sitemap.xml. A single remaining HTTP link can trigger "Mixed Content" warnings.
Step 4, Fix the Mixed Content
"Mixed Content" happens when an HTTPS page loads HTTP resources (images, scripts, iframes). Chrome blocks them and shows a broken padlock. Diagnostic tool: Why No Padlock (free), which lists every HTTP resource you need to fix.
Step 5, Update Google Search Console
Add the HTTPS property in Search Console (it is a separate property from the HTTP one). Submit your updated sitemap. Check for crawl errors in the 48 hours after the migration.
Performance bonus: switch on HSTS (HTTP Strict Transport Security) in your server's HTTP headers. After the first visit the browser remembers that your site is HTTPS and skips the redirect on every later visit, saving 50 to 100ms per load.

Frequently asked questions about SSL and HTTPS
Is my WordPress site automatically on HTTPS?
No. The SSL certificate comes from your host, not from WordPress. If your host offers Let's Encrypt (OVH, PlanetHoster, Infomaniak), switch it on from your control panel, then install the Really Simple SSL plugin to migrate every internal URL automatically. If your host does not offer free SSL in 2026, change host: it is an absolute standard and should not cost anything. Once it is active, clear the WordPress cache (through WP Rocket, LiteSpeed Cache or W3 Total Cache) and check that Yoast or Rank Math has updated the sitemap with https:// URLs, because a sitemap still on http:// would delay Google's re-indexing by several weeks.
Does moving to HTTPS cost you rankings?
Done properly (301 redirects, Search Console updated, Mixed Content fixed), moving to HTTPS keeps your SEO entirely intact. Google passes PageRank through permanent 301 redirects. A botched migration can cause a temporary dip of 2 to 4 weeks, usually the time Google needs to re-index the new URLs. Follow the 5 steps in order and you will not lose ground.
Are there sites that cannot get a free SSL certificate?
Let's Encrypt covers every standard domain name. The rare unsupported cases: bare IP addresses with no domain name, and very old hosts running on infrastructure that was never updated. In those cases a paid DV certificate (under 50€ a year from Sectigo or DigiCert) solves it. The simplest answer is still to move to a modern host: in 2026, Vercel, Netlify and any recent shared hosting all include HTTPS automatically.
Does HTTPS slow the site down because of the encryption?
No, that is a myth from an era when encryption was expensive in CPU terms. In 2026, with TLS 1.3, the performance cost of encryption is close to zero (< 1ms). The opposite is true for modern sites: HTTPS is faster than HTTP because it unlocks HTTP/2 and HTTP/3, which load resources in parallel and compress headers. Moving to HTTPS usually improves your PageSpeed score by 5 to 15 points.
How do you check that your site really is on HTTPS?
Three quick checks: (1) open your site in Chrome and look at the address bar, a padlock means valid HTTPS, an orange triangle means Mixed Content, and "Not secure" means plain HTTP, (2) type site:yourdomain.com into Google, every URL listed should start with https://, (3) test with SSL Labs (ssllabs.com/ssltest), which grades your certificate configuration from A to F and flags any weaknesses.
