Speeding Up a Slow WooCommerce Store, Step by Step

WooCommerce stores slow down gradually — a plugin here, an uncompressed product image there — until checkout is taking four seconds to load and nobody remembers why.

The first pass is always a plugin audit. Stores accumulate plugins for one-off tasks that never get removed, and each one adds its own database queries and script loads on every page.

Image pipelines are the second biggest win: serving properly sized, modern-format images instead of the original upload can cut page weight dramatically on product-heavy catalogues.

Database cleanup — expired transients, orphaned post meta, revision bloat — and a properly configured caching layer usually finish the job. None of this requires a full rebuild; it requires actually looking at what's slowing the site down instead of guessing.
