HTTPS vs HTTP: Why Unencrypted Websites Get Flagged

January 29, 20169 min readWebsite Security

HTTPS is no longer optional — if your website still loads over plain HTTP, modern browsers actively warn visitors that the connection is "Not Secure," and search engines quietly push you down the rankings. What began as a gentle nudge from Google has become a hard baseline: an encrypted, trustworthy website is the price of entry for being taken seriously online. In this guide you'll learn what HTTPS actually does, why it matters for security, SEO and conversions, how to migrate without losing rankings, and the practical steps Indian businesses should take to keep their sites safe and visible.

Editor's note: this article was first published in 2016, when Google engineers were just beginning to publicly "call out" unencrypted HTTP sites and Chrome started experimenting with security warnings in the address bar. That experiment has since become standard behaviour across every major browser. The piece below has been rewritten as an evergreen guide; specific product states from 2016 are not presented as current.

HTTPS (Hypertext Transfer Protocol Secure) is the standard HTTP protocol wrapped in an encryption layer (TLS) that protects data travelling between a visitor's browser and your web server from snooping, interception and tampering. Where old-style HTTP sends everything in plain text that anyone on the network can read, HTTPS scrambles it — which is exactly why browsers and search engines now treat unencrypted sites as a liability.

Illustration contrasting an insecure HTTP connection with a secure HTTPS padlock in the browser address bar — Browsers now display a clear security indicator: a padlock for HTTPS, and a "Not Secure" warning for plain HTTP.

Why Google Started "Coming to Get" Unencrypted Sites

The shift was deliberate and public. Google's security engineers argued that users have no easy way to tell whether a connection is private, so the browser should make the risk obvious. The plan was simple: instead of a neutral, blank indicator for HTTP, browsers would mark unencrypted pages with a visible warning — first a subtle change, then an explicit "Not Secure" label.

That philosophy stuck. Today, when a visitor lands on an HTTP page — especially one with a login box or a payment form — the browser flags it plainly. For a business, that warning appears at the worst possible moment: just as a potential customer is deciding whether to trust you with their details.

What the Warning Actually Means to a Visitor

Most people don't know what TLS is, but they understand "Not Secure." It reads as "this company is careless" or "my information isn't safe here." On a brochure site it dents credibility; on a checkout or enquiry page it can quietly kill the conversion. The encryption is technical, but the consequence is purely commercial.

The Three Reasons HTTPS Is Non-Negotiable

Encryption isn't a single benefit — it solves three different problems at once, which is why it has become a universal standard rather than a nice-to-have.

Security and privacy: TLS encrypts form submissions, passwords, payment data and browsing activity so they can't be read or altered in transit by attackers on shared or public networks.
Search visibility: Google has publicly confirmed HTTPS as a ranking signal. It is a lightweight signal on its own, but when competing pages are otherwise equal, the secure one has the edge — and an unencrypted site sends the wrong trust signals across the board.
User trust and conversions: The padlock and the absence of a warning reassure visitors. Trust is the foundation of every enquiry, sign-up and sale, and a "Not Secure" label erodes it instantly.

HTTP vs HTTPS: A Side-by-Side Comparison

Aspect	HTTP (unencrypted)	HTTPS (encrypted)
Data in transit	Plain text, readable by anyone on the network	Encrypted via TLS
Browser indicator	"Not Secure" warning	Padlock / neutral secure state
Tampering / injection	Possible (e.g. injected ads, malware)	Protected against in-transit tampering
SEO treatment	No ranking benefit; trust signals weakened	Confirmed positive ranking signal
Suitability for forms/payments	Unsafe and discouraged	Required
Modern features (HTTP/2, PWAs, etc.)	Often unavailable	Supported

How HTTPS Encryption Works (In Plain English)

When a browser connects to an HTTPS site, it performs a quick "handshake" with the server. The server presents an SSL/TLS certificate — a digital document, issued by a trusted Certificate Authority, that proves the site is who it claims to be. The browser verifies that certificate, and the two sides agree on encryption keys for the session.

From that point on, everything exchanged is scrambled. Even if someone intercepts the traffic — on café Wi-Fi, a shared office network, or anywhere in between — they see meaningless ciphertext rather than your customer's password or card number. The certificate also confirms identity, which helps guard against impersonation and certain phishing tactics.

Migrating from HTTP to HTTPS Without Losing Rankings

Switching to HTTPS is a routine, well-understood project — but it must be done carefully so search engines treat the secure version as the same site, not a brand-new one. A clean migration protects the rankings and traffic you've already earned.

Get a valid SSL/TLS certificate. Many hosts and CDNs offer free, automatically renewing certificates; choose one appropriate to your site and renew it reliably.
Install and configure it on your server so the whole site — not just the checkout — is served over HTTPS.
Redirect HTTP to HTTPS with permanent (301) redirects so old links and bookmarks land on the secure version and pass on their value.
Fix mixed content. Update any images, scripts, stylesheets or embeds still referenced over HTTP, otherwise the browser may still show a partial-security warning.
Update internal links, canonical tags and sitemaps to point to the HTTPS URLs.
Re-verify in Google Search Console and resubmit your sitemap so Google re-crawls the secure version.
Test thoroughly across pages, forms and devices, and monitor traffic and rankings for a few weeks afterwards.

If migrations make you nervous, that's reasonable — a botched redirect map or unresolved mixed content can dent visibility temporarily. This is the kind of work where an experienced web development and SEO services team pays for itself, getting the transition right the first time.

HTTPS Is the Foundation, Not the Finish Line

Encryption secures the connection, but a genuinely safe and high-performing website needs more. HTTPS sits at the base of a broader stack of good practice that protects both your business and your customers.

Security Beyond the Padlock

A certificate doesn't patch vulnerable plugins, weak passwords or outdated software. Pair HTTPS with regular updates, sensible access controls and periodic checks — our guide to a cyber security audit for your website and app and our overview of cybersecurity for Indian SMEs walk through what a layered approach looks like in practice. Protecting customer information also means thinking about data protection for SMEs.

Speed, Mobile and Conversions

HTTPS unlocks modern performance features and is expected by mobile users. A secure, fast, responsive website keeps visitors engaged — and if you're getting traffic but few enquiries, the cause is often trust and experience rather than volume, as we explain in why website traffic doesn't convert into leads.

Security Signals and Modern SEO

Trust signals like HTTPS feed into the wider picture of how search engines — and increasingly AI answer engines — judge your site. For the bigger strategy, see our complete SEO guide for Indian businesses and how to prepare for AI-driven search results.

Frequently Asked Questions

Will switching to HTTPS improve my Google ranking?

Google has confirmed HTTPS as a positive ranking signal, though it is a lightweight one. On its own it won't vault you to the top, but it removes a trust disadvantage and, when other pages are equal, gives the secure site the edge. It is best seen as a necessary foundation rather than a growth tactic by itself.

What does the "Not Secure" warning in the browser mean?

It means the page is being served over plain HTTP without encryption, so data sent between the visitor and the site could be intercepted or read. Browsers show this to warn users, and it is especially damaging on pages with login or payment forms because it appears right when visitors are deciding whether to trust you.

Is an SSL certificate the same as HTTPS?

They're closely related. An SSL/TLS certificate is the digital credential that proves your site's identity and enables encryption; HTTPS is the secure protocol that uses that certificate. In short, installing and configuring a valid certificate is what turns your HTTP site into an HTTPS one.

Can I move to HTTPS without losing my existing SEO rankings?

Yes, if the migration is done properly. The key steps are using permanent 301 redirects from HTTP to HTTPS, fixing any mixed-content references, updating internal links and canonical tags, and re-verifying the site in Google Search Console. Done carefully, rankings transfer to the secure version.

Does HTTPS make my website completely secure?

No. HTTPS secures data in transit, but it doesn't protect against vulnerable software, weak passwords or unpatched plugins. It's a vital foundation that should be combined with regular updates, access controls and periodic security audits for genuine protection.

Do small business and brochure websites really need HTTPS?

Yes. Even sites without logins or payments are flagged as "Not Secure" over HTTP, which undermines credibility, and they still miss out on the trust and SEO benefits. With free certificates widely available, there is no practical reason for any business site to remain unencrypted.

Bottom line: HTTPS is the baseline of a trustworthy online presence. If your website still loads over HTTP, or you migrated long ago and aren't sure it's configured correctly, it's worth a proper review.
