Static WordPress refers to replicas of WordPress sites that are delivered as pre-rendered files and pages (aka “static”), and are completely disconnected from the servers that can slow sites, or get hacked (aka “headless”). That’s why static sites are so fast, secure and resilient.
With regular WordPress websites, the front end (the website) and the backend (the WP admin) are tightly conjoined and always available – both to visitors and attackers. To generate website pages, servers publish them on-the-fly for users as they request to see them in their browser. This process is resource and time intensive, and can lead to performance issues. The conjoined nature of the site also means that all the layers of WordPress and its ongoing vulnerabilities are exposed and can get hacked at any time.
To solve the speed and security issues inherent in traditional WordPress, website owners invest huge amounts of resources in optimizing their sites.
Traditional optimization usually includes: Caching plugins, Firewalls, Security plugins, Backup plugins, Security scans and CDNs.
These tools can be complicated to implement and maintain, can conflict with one another, and often don’t generate the desired results. Sites can still get hacked, and are still sluggish.
