Start with display size and visual quality, then choose a format and loading strategy. A smaller file is useful only if the right image reaches the right screen.
Read the guideChoose the right cache layer
Different caches store different things. Identify which layer applies to the slow request before changing settings or installing another plugin.
Read the guideA fit-first cache decision
Choose a performance tool that fits the server and existing configuration. Neither plugin removes the need for diagnosis, exclusions and regression testing.
Read the guideDeliver closer. Cache carefully.
A CDN can improve eligible content delivery, but it does not repair every server or browser bottleneck. Define what is cached and what must remain dynamic.
Read the guideKeep the design. Reduce the work.
Audit the templates and widgets visitors actually use. Elementor performance work should preserve the editor, responsive design and important interactions.
Read the guideProtect the purchase journey
Checkout is personalised and should not be served as a shared cached page. Investigate the slow request and preserve native order and payment verification.
Read the guideKeep the page steady
Reserve space for content before it arrives and check for movement throughout the visit. A stable first screen does not rule out later layout shifts.
Read the guideRead the right speed evidence
Lab tests help diagnose a page now. Field data describes sampled real visits over time. They answer different questions and should be reported separately.
Read the guideMake every tap count
A page can look finished and still respond slowly. Reproduce the delayed action and inspect the work surrounding it before changing scripts.
Read the guideMake mobile visits easier
A mobile audit should cover loading, tapping, reading and submitting. A narrow desktop window alone does not reproduce a real phone.
Read the guideBring the main content forward
Identify the largest content element first. The right fix depends on whether the delay occurs before the document, during resource loading or before rendering.
Read the guideFind the real bottleneck
Start with the slow task and its evidence. A slow first response, a late hero image and a frozen menu need different fixes.
