HTTPS is pure AI-visibility hygiene, but the kind you cannot skip: a missing, expired or misconfigured SSL certificate is a trust and security red flag that can get your pages down-weighted, flagged as insecure, or skipped by the crawlers assistants rely on, and it undermines the 'legitimate, real business' signal models look for before naming you. It won't earn you a recommendation on its own — no security setting does — but running your whole site on valid HTTPS, with no mixed-content warnings and clean http-to-https redirects, ensures nothing about your basic security posture quietly disqualifies you or scatters your authority across insecure and secure URL variants. In 2026 this is universal table stakes; the only real work is confirming the certificate is valid, every page redirects to the secure version, and there are no lingering insecure resources dragging down pages you want AI to read and trust.
