HTTP vs HTTPS
There is no real comparison left — HTTPS is required. Browsers mark HTTP pages as not secure, many browser features refuse to work without it, and certificates have been free with automated renewal for a decade.
Side by side
| Compared on | HTTP | HTTPS |
|---|---|---|
| Traffic readable in transit | Yes | No |
| Browser warning | Marked not secure | None |
| Modern browser features | Many unavailable | Available |
| Ranking signal | Negative in practice | Positive, lightweight |
| Cost | Free | Free |
When HTTP is the right choice
- Nothing on the public web
- Purely local development on your own machine, where certificates are inconvenient
When HTTPS is the right choice
- Every public site, without exception
- Anything accepting form input of any kind
- Anything you want indexed or trusted
Doing it properly rather than merely doing it
- HTTP redirects to HTTPS in one hop, not through www and back
- HSTS enabled so browsers refuse to downgrade
- No mixed content — a single http:// asset undermines the page
- Certificate renewal automated, because manual renewal is a diary entry somebody misses
The failure that takes a site offline
An expired certificate produces a full-page browser interstitial that stops every visitor. It is entirely preventable with automated renewal and monitoring, and it is one of the most common ways a small business site goes dark for days unnoticed.
The migration, if you are still on HTTP
- Install a certificate — free, automated, on any serious host
- Fix mixed content: search templates and the database for http:// references
- Redirect every HTTP URL to its HTTPS equivalent in one hop
- Update canonicals, sitemaps, and internal links to the HTTPS version
- Add the HTTPS property in Search Console and submit the sitemap again
- Enable HSTS once you are confident nothing is broken
The verdict
Not a decision. The only useful question is whether your HTTPS is configured properly — single-hop redirects, HSTS, no mixed content and automated renewal.
