What is ssl cert expiring soon?

An SSL/TLS certificate is the digital credential that proves your website is who it says it is and encrypts the connection between your store and your customers' browsers — it's what puts the padlock icon and "https://" in the address bar. Every certificate has an expiry date, after which browsers will show a full-screen red warning ("Your connection is not private") to anyone who tries to visit your site. Renewing means getting a fresh certificate installed before the old one runs out. Most certificates last 90 days to 1 year, and renewal should be started at least 30 days before expiry to allow time for any issues.

When your certificate expires, every major browser — Chrome, Safari, Firefox, Edge — will block visitors with a hard security warning before they even see your store. This instantly destroys trust and conversions: most shoppers will leave and never return. Google also uses HTTPS as a ranking signal, so an expired certificate can hurt your organic search visibility. If you collect any customer data (names, emails, payment info), operating without a valid certificate exposes that data to interception and puts you at legal risk under privacy regulations such as GDPR and PCI-DSS. Even a single day of expiry can cause lasting damage to your brand reputation.
