SSL Certificate (HTTPS)
A digital certificate that authenticates a website's identity and enables an encrypted connection.
An SSL (Secure Sockets Layer) certificate is no longer optional. It changes your site from HTTP to HTTPS, adding the “padlock” icon in browser bars. This is the first thing users and search engines look for to verify a site is safe.
Why It Matters for Authority
- User Trust: Users are trained to avoid “Not Secure” websites.
- SEO Ranking: Google explicitly uses HTTPS as a ranking signal.
- Data Protection: It encrypts sensitive information like lead form data.
