Mobile Page Weight and Media Audit
Check heavy elements on small screens.
The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.
Audit weight. Page assets with sizes: [ASSET_LIST]. Target page weight: [TARGET_WEIGHT]. Identify oversized images, unneeded scripts and fonts, autoplay media and layout shifts. Propose savings with arithmetic, such as converting an image of 1.2 MB to 300 KB. Return a table and a quick-win list. Add a worked saving: hero image 1.8 MB to 250 KB after resizing and compression saves 1.55 MB; two unused scripts of 90 KB and 140 KB removed save 230 KB; font files 300 KB reduced to 120 KB by subsetting. Total saving about 1.55 MB + 0.23 MB + 0.18 MB = 1.96 MB. Estimate load time change on a slow connection and verify by testing. Add a performance budget of 1 MB for the first load and a monthly check. Add a closing step: re-measure after changes and record the new page weight, comparing it with the budget. Add a closing note: set a performance budget in the build process so heavy additions are caught before they reach customers, and review the budget each quarter.
