Images, videos and animations are often the most important multimedia resources on a page. By optimizing these files, we can reduce loading times and cut emissions.

Web pages that use scripts, media or other unnecessary elements can slow down page performance, frustrate users and increase download times and broadcasts. We offer users fast, lightweight pages by removing all unnecessary elements.

Third-party plugins, widgets and frameworks often introduce unnecessary code snippets into our page, which can have a negative impact on download speed and performance.

Broadcast images of appropriate size to save cellular data and improve loading time.

Remove large, duplicate JavaScript modules from bundles to reduce unnecessary bytes consumed by network activity.

Third-party code can have a significant impact on loading performance. Limit the number of redundant third-party providers and try to load third-party code once our main page has finished loading.

Studies have shown that users quickly leave pages that don’t display content. Page content “above the waterline” must be displayed on a user’s device in no more than 2.5 seconds. This is particularly crucial in low-bandwidth areas and for users with older devices.

Pages that respond slowly or don’t respond as expected to user interactions (such as button clicks, key presses, form entries, etc.) consume more energy and frustrate users.

Pages that use SEO best practices help users find content more quickly, thus reducing the energy used during search. Search-optimized pages also tend to be more accessible and work on a wider range of devices and platforms. This reduces the amount of energy (and frustration) expended by users when obstacles exist.

Accessible pages tend to work on a wider range of devices and platforms, including assistive technologies used by people with disabilities. Prioritizing accessibility reduces the amount of energy (and frustration) expended by users when obstacles exist. What’s more, it’s exactly the right thing to do.

A long cache life can speed up repeat visits to your page.

Set an explicit width and height on image elements to reduce layout changes and improve the experience.

Page redirects lead to slower page speeds. Pages are flagged if they contain two or more redirects. To avoid this, we consult the list of redirects and update the links to point directly to the actual location of each resource. This will eliminate unnecessary redirects and reduce loading times.

Consider marking your touch and wheel event listeners as “passive” to improve your page’s scrolling performance.

Consider adding “preconnect” or “dns-prefetch” resource hints to establish early connections with important third-party origins.

Every time your page makes a request to the server, energy is required to transfer and display the data. Reducing the number of requests made to our pages can improve performance and reduce emissions.
