Security

Mixed content and the response headers a browser expects from a site served over HTTPS.

High

The server lists a directory instead of serving a page

Turn off automatic directory indexes on the server: the listing names files that were never meant to be addresses.

High

A form on a secure page posts over http

Point the form’s action at the https address: browsers warn before sending it and Chrome refuses outright, so the form is both unsafe and broken.

High

A string that looks like a live key is in the page source

Revoke the key, issue a new one and keep it on the server — the page source is public, so never print a secret into HTML or inline JavaScript.

TLS certificate expiring soon

Renew the certificate and confirm automatic renewal is running: when it lapses, every browser blocks the site outright.

Cookies set without Secure, HttpOnly or SameSite

Set Secure, HttpOnly and SameSite on the cookies the site issues, so they cannot travel over http, be read by a script, or be sent from another site.

No contact, about or privacy page

Publish and link a contact page, an about page and a privacy policy: buyers and quality raters both look for them first.

Mixed content on a secure page

Change http:// asset URLs (images, scripts, styles) to https:// so browsers stop warning.

Redirect passes through plain http

Send every hop straight to its https address; a chain that ends secure can still travel in the clear.

No verifiable business details on the site

Put a phone number, a postal address and a company or VAT number where a reader can see them, usually in the footer.
