Set up caching plugin

Site performance is poor on the storefront page. Install and configure a caching plugin: enable page cache, set cache lifetime to 12 hours, enable gzip compression, and activate browser caching for static assets. Purge the cache and check the storefront, 10 product pages, and the cart to confirm faster load times. Tell Sam the change is live and include before-and-after load times.

Before I install a caching plugin, make it easy for stakeholders to approve changes: list which dynamic areas need cache exclusions (cart, account, checkout), surface plugin compatibility risks with our current theme and security plugin, and flag how caching will alter testing for QA and deployment windows.

I enabled page caching and customers now see stale cart contents. I’m afraid I broke checkout behavior but I don’t know which cache rule is at fault. What checks will identify which pages need bypassing, and what is the quickest safe rollback to restore correct cart behavior while keeping site speed improvements elsewhere?

We keep deploying caching rules that speed the site but break dynamic features like the cart and account pages. Where are we losing time—insufficient cache exclusion lists, poor testing, or rollout timing—and what single habit should we adopt to prevent caching regressions across client sites?
